NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 5 Communicable Disease CHAPTER 1: SOCIODEMOGRAPHIC CHARACTERISTICS OF THE GENERAL POPULATION IN NORTH CAROLINA HIGHLIGHTS In 2009, North Carolina was the 10th most populous state in the U.S., with an estimated population of 9,535,483. North Carolina’s population increased 18.5 percent from 2000 to 2010. In 2009, North Carolina ranked 3rd in the nation for annual population increase. The N.C. foreign-born population increased 38 percent from 2002 to 2008. North Carolina has the 18th largest non-white population in the nation. North Carolina has the 8th highest percentage of black population in the nation. North Carolina has the 26th largest Hispanic/Latino population and the 10th highest birth rate among Hispanics in the nation. The median age for the Hispanic population was 23.7 years, while the median age for all North Carolinians was 38.3 years in 2008. In 2010, North Carolina was 37th in the nation with a per capita income of $35,638 or 87.8 percent of the national average of $40,584. From 2008 to 2009, 19.7 percent of North Carolinians were living at or below the federal poverty level (FPL); 39.9 percent of the overall population is considered low income (living at or below 199% FPL). From 2008 to 2009, 23 percent of the 19 to 64 year old population in North Carolina was uninsured. About 19 percent of the N.C. population was eligible for Medicaid coverage at some point during 2009. About 70 percent of the state’s population lived in urban areas in 2009. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 6 Communicable Disease SOCIODEMOGRAPHIC CHARACTERISTICS OF NORTH CAROLINA Knowledge of sociodemographic characteristics is paramount to fully understanding the health of a population. Sociodemographics can be used to identify certain populations that may be at greater risk for morbidity and mortality. This knowledge can also assist in identifying underlying factors that may contribute to a health condition. This chapter will discuss the relevant health indicators and sociodemographic characteristics of the population of North Carolina, including age, race/ethnicity, gender, income, poverty, education, and geography. Population According to the 2010 federal census, North Carolina was one of the most rapidly expanding states during the previous decade. From 2000 to 2010, North Carolina’s population grew by 18.5 percent, from 8,049,313 to 9,535,483. Only five other states (Arizona, Idaho, Nevada, Texas, and Utah) grew faster during the last decade. From 2008 to 2009, North Carolina ranked 3rd for single year population growth. According to the N.C. State Demographer, the 2010 North Carolina State provisional population estimate was 9,572,454, with county populations ranging from 4,403 (Tyrrell) to 923,944 (Mecklenburg). More than one-half of North Carolina’s population lived in only 16 counties (Mecklenburg, Wake, Guilford, Forsyth, Cumberland, Durham, Buncombe, Gaston, New Hanover, Union, Onslow, Cabarrus, Johnston, Davidson, Pitt, and Iredell). From July 2008 to July 2009, there were 129,618 births and 79,441 deaths. The average life expectancy for North Carolinians was 75.8 years. The most updated gender and age-specific population information available is for the year 2009, so we use the 2009 population as a substitute for 2010 in order to analyze the HIV disease rates in this profile. In 2009, North Carolina was the 10th most populous state in the United States with an estimated population of 9,380,884 (US Census 2009 population estimate), representing a 16.1 percent increase from that of year 2000. Map 1 displays the population distribution among the counties in North Carolina for 2009 (Appendix A, pg. A-3). Age and Gender Age and gender play an important role in public health planning and in understanding the health of a community. These characteristics are significant indicators of the prevalence of certain diseases, especially for HIV disease and other STDs, as shown in previous Epidemiologic Profiles. Substantial morbidity and social problems among youth are the result of unsafe sex practices, which can result in unwanted pregnancies and STDs, including HIV infection. Nearly one-half of all new sexually transmitted diseases in North Carolina occur in youth ages 15 to 24 years. Research shows that adolescents (ages 13–19 years) are at increased risk, both behaviorally and biologically, for HIV infection. Of the adolescents infected with HIV, more than half are estimated to be unaware of their status due to never having been tested (Rotheram- Borus and Futterman 2000). In 2009, the median age for people living in North Carolina was 36 years old, with 25.7 percent 18 years and younger, and 12.7 percent 65 years and older. Approximately 49 percent of the population is male and 51 percent is female. Table 1.1 displays the North Carolina population in NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 7 Communicable Disease 2009 by selected gender and age groups. The trend in North Carolina follows the typical age trend of slightly more males under 12 years old and more females in the older age groups. North Carolina has a younger population than other states, ranking 10th in the nation in 2009 with more people under 18 years of age. North Carolina’s young population might have extensive health-related needs, such as STDs and unwanted pregnancies. Table 1.1.

Table 1.2 displays the percentages of males and females for the major race/ethnicity categories by North Carolina regions. Race/ethnicity also varies by region with a larger proportion of white non-Hispanics in Western Region, American Indians in Eastern Region, and black non-Hispanics in Eastern Region. A state map showing the N.C regions is displayed on the inside back cover. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 8 Communicable Disease Race/Ethnicity and Gender The racial and ethnic differences of a population play an important role in interpreting gaps in access to health care among the different groups, and these differences are especially true in terms of HIV disease surveillance and intervention. Previous HIV disease surveillance showed that HIV disproportionately affected ethnic minorities in North Carolina. North Carolina has the 18th largest non-white population in the United States (3,058,647 in year 2009) and there are noticeable variations in the demographic composition of North Carolina from region to region. Usually non-white minorities have poorer health conditions and less access to health care. In 2009, 14 counties had populations consisting of more than 50 percent non-white residents (Robeson: 71.0%; Hertford: 65.1%; Bertie: 64.9%; Edgecombe: 61.6%; Warren: 61.4%; Northampton: 59.8%; Halifax: 59.4%; Vance: 56.9 %; Hoke: 55.8%; Washington: 55.0%; Durham: 54.2%; Greene: 53.6%; Anson: 51.3% and Scotland: 50.7%). Maps 3-6 (Appendix A, pp.A-5 to A-8) display the racial and ethnic make-up of North Carolina’s counties, as reported in the 2009 bridged-race estimates (please see Appendix C, pg. C-5 for more information about Census data and the bridged-race categories used to calculate rates). Table 1.3 displays the populations for the major race/ethnicity categories in North Carolina according to the bridged-race estimates for 2009. Table 1.2.

According to the N.C. Health Profile 2009, compared to whites, blacks have higher death rates from heart disease, cancer, HIV, diabetes, homicide, and stroke. North Carolina has seven counties with blacks consisting of more than 50 percent of the total population (Bertie 62.9 %, Hertford 61.3%, Northampton 57.9%, Edgecombe 56.4%, Halifax 53.8%, and Warren County 53.0%). Map 3 (Appendix A, pg. A-5) displays the proportion of black population in 2009 by county. Hispanics Over the years, the N.C. Hispanic population has steadily increased. From 2002 to 2009, the estimated Hispanic/Latino population increased from 451,095 to 717,662, representing a 59.1 percent increase. Hispanics represented 7.7 percent of the population of the state and ranked 26th nationally. North Carolina ranked 10th in Hispanic births in 2008. Compared to other ethnic groups in North Carolina, Hispanics are a relatively young population. Although the median age of the non-Hispanic population is 38.3 years, the median age of Hispanics is 23.7 years. Seventy percent (70%) of Hispanics are under 35 years old, while only 46 percent of non-Hispanic population is in the same age range. Map 5 (Appendix A, pg. A-7) displays the proportion of the Hispanic population in 2009, by county. Within North Carolina, Duplin County had the highest proportion of Hispanic residents (22.0%), followed by Sampson County (17.0%), Lee County (17.0%), and Montgomery County (16.5%). American Indians American Indians represent 1.2 percent of the N.C. population and are one of the largest American Indian populations in the U.S. About 45 percent of American Indians in North Carolina live in Robeson County, followed by Cumberland, Hoke, Mecklenburg, Wake, Jackson, and Scotland counties. Map 4 (Appendix A, pg. A-6) displays the proportion of the American Indian population in 2009 by county. The 2009 N.C. Health Profile shows that American Indians experience higher death rates due to heart disease, stroke, homicide, diabetes, kidney disease, and unintentional motor vehicle injuries compared to the white population. Foreign-born Population According to the Center for Immigration Studies, North Carolina has experienced a dramatic increase in its immigrant population. The immigrant population in North Carolina has increased three and one-half times between 1995 and 2007 (Camarota, 2007). According to the US Census Bureau’s Annual American Community Survey, North Carolina’s foreign-born population increased by 38 percent from 2002 to 2008 (480,248 to 665,270). In 2006, North Carolina ranked 15th nationally for the admitted number of immigrants from other countries. In 2009, 30.6 percent of the foreign-born populations in North Carolina were naturalized citizens, while 69.4 percent were not citizens. The various regions of birth are displayed in Table 1.4. The majority (57.3%) of the foreign-born population come from Latin America, with the other 22.2 percent NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 10 Communicable Disease from Asia, 11.7 percent from Europe, 5.7 percent from Africa, 2.7 percent from North America, and 0.5 percent from Oceania. The majority of the 2009 foreign-born population was male (52.8%) as opposed to female (47.2%). A majority (50%) of the foreign-born population is between ages 25 to 44 years (Table 1.5). About 83 percent speak a language other than English at home and 50 percent do not speak English “very well.” Table 1.3.

These areas are collectively referred to as Core Based Statistical Areas (CBSAs), with a metro area containing a core urban area of 50,000 or more population, and a micro area containing an urban core of at least 10,000 (but less than 50,000) population (U.S. Census Bureau, Population Division). A complete listing of all micropolitan, metropolitan, and combined statistical areas can be obtained at the following website: http://www.census.gov/population/www/estimates/metrodef.html. In the HIV/AIDS Surveillance Supplemental Report, Volume 13 Number 2, the Centers for Disease Control and Prevention (CDC) divides metropolitan areas into large (population greater than or equal to 500,000) and medium-sized metropolitan areas (population 50,000 to 499,999), which are all defined as urban areas. Areas other than metropolitan areas (including micropolitan and non-metropolitan areas) are defined as rural areas. Eleven North Carolina counties, including Anson, Cabarrus, Franklin, Gaston, Guilford, Johnston, Mecklenburg, Randolph, Rockingham, Union and Wake County, are classified as large metropolitan areas, while other metropolitan counties are classified as medium-sized metropolitan areas. About 35 percent of the N.C. population resides in large metropolitan areas, 35 percent in medium-sized metropolitan areas, 22 percent in micropolitan areas, and 8 percent in non-metropolitan areas in 2009. Asian and Pacific Islanders have the highest proportion (56.7%) living in the large metropolitan areas, followed by Hispanics (42.9%). Similar proportions (around 34%) of all race/ethnic groups, except American Indians (18.0%), live in medium-sized metropolitan areas. Data from the U.S. Census showed that in 2006, 65 percent of the general population of the United States was living in large metropolitan areas, 19 percent in medium-size metropolitan areas, and 17 percent in areas other than metropolitan, i.e. rural areas. Compared to national figures, North Carolina has less people in urban areas, substantially less in large metropolitan NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 12 Communicable Disease areas, and more people in rural areas. In North Carolina, a majority of Asians (88%) live in urban areas, followed by Hispanics (76%) and blacks (72%). A majority of American Indians (69%) live in rural areas (Tables 1.6 and 1.7). North Carolina’s metropolitan and non-metropolitan counties are displayed in Map 2 (Appendix A, pg. A-4). Table 1.6.

HEALTH INDICATORS Poverty and Income Contextual factors such as poverty, income, and education, as well as racial segregation, discrimination, and incarceration rates influence sexual behavior and sexual networks. These factors likely contribute substantially to the persistence of marked racial disparities in rates of STDs (Adimora and Schoenbach 2005). NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 13 Communicable Disease According to the US Department of Commerce’s Bureau of Economic Analysis, the 2010 per capita income for North Carolina is $35,638, or 87.8 percent of the national average of $40,584. This figure represents a 2.5 percent decrease from 2009 and placed North Carolina 37th in the nation for personal per capita income and 4th in the Southeast. Economic recession has impacted North Carolina more than the national average. According to the Bureau of Labor Statistics, the unemployment rate in North Carolina rose from 5.0 percent in January 2008 to 8.5 percent in December 2008 to 11.3 percent in December 2009 but has gone down slightly to 9.8 percent in December 2010. These rates are all higher than the national unemployment rate (the national unemployment rate was 5.0 percent in January 2008 to 7.3 percent in December 2008 to 9.9 percent in December 2009 and to 9.4 percent in December 2010) (Bureau of Labor Statistics). According to Income, Earnings, and Poverty Data from the 2009 American Community Survey, 16.3 percent of North Carolinians are living under the poverty line (while 14.3% nationally). From 2008 to 2009, 19.7 percent of North Carolinians were below the federal poverty level (FPL); with an overall total of 39.9 percent of the population considered low income (199% or below FPL). The median household income in North Carolina was $43,674, a figure much lower than the national median of $50,221. North Carolina ranked 14th in percentage of people in poverty in 2009. Table 1.8 displays the individual poverty rate by age group for the state (2008– 2009) and the nation (2009). Table 1.9 displays the individual poverty rate by race/ethnicity for North Carolina and the United States (2008–2009). Map 7 (Appendix A, pg. A-9) displays the N.C. per capita income for 2009 by county. Health Insurance The percentage of the non-elderly without health insurance in North Carolina has been increasing over the years. In North Carolina (2008–2009), 23 percent of persons ages 19 to 64 years were uninsured (statehealthfacts.org. Kaiser Family Foundation). The primary reason people lack health insurance is financial. According to statehealthfacts.org, 39 percent of the non-elderly (0–64 year olds) uninsured had incomes less than 100 percent of the Federal Poverty Guidelines. Table 1.8.

Kaiser Family Foundation). The racial distribution of non-elderly uninsured people in North Carolina is displayed in Figure 1.1. Figure 1.2 displays the uninsured rates by race/ethnicity for North Carolina as compared to the United States. In 2008 to 2009, 47 percent of Latinos or Hispanics, 22 percent of blacks, 13 percent of whites, and 25 percent of other races were uninsured in North Carolina (statehealthfacts.org. Kaiser Family Foundation). Rates of uninsured among all racial/ethnic groups in North Carolina were higher than those in the nation. Although whites comprise the greatest proportion of the uninsured population (Figure 1.1), minorities have the highest uninsured rates (Figure 1.2). Hispanics in North Carolina are more likely to be uninsured because they are often recent immigrants with low-wage jobs in industries that do not offer health insurance. Table 1.9.

Medicaid recipients by race, 2008 Black* 38% White* 45% Other 17% *non-Hispanic Education According to the 2009 American Community Survey, 84.3 percent of North Carolinians who were 25 years or older had a high school diploma or higher and 26.5 percent had a bachelor’s degree or higher. Around five percent of high school students (grades 9–12) dropped out during the 2008 to 2009 school year (N.C. Public Schools Statistical Profile, 2010). Internet access To some extent, health education depends on the facilities at home and in the communities. The internet has become one of the most important venues in health education. In 2007, North Carolina ranked 42nd for the percentage of households with computers (57.7%), and 40th for the percentage of households with internet access (56.8%). Public Aid Total Medicaid and Medicaid-related expenditures in North Carolina for State Fiscal Year (SFY) 2008 were approximately $9 billion for approximately 1.7 million Medicaid recipients (an average $5,262 per recipient). The number of Medicaid recipients increased by 2.6 percent from 2007 to 2008. A total of 1,726,412 North Carolinians, or 18.7 percent of the total N.C. population, received at least one Medicaid service during the 2008 fiscal year (N.C. Medicaid Report 2008). Among them, 40 percent were male and 60 percent were female. Elderly and Disabled recipients comprised about 13.1 and 15.5 percent of total Medicaid recipients, respectively, and their expenditures amounted to $6.2 billion or 65 percent of the total service expenditures. Families and Children comprised 70 percent of all recipients, accounting for $3 billion or about 34 percent of total service expenditures. Aliens and Refugees represented 1.3 percent of all recipients and accounted for about $67.8 million, or about 0.8 percent of total service expenditures. Of all Medicaid services provided, Nursing Facility, Inpatient Hospital, Prescription Drug, and Non-Physician Practitioner services were the top four expensive services and accounted for about $4 billion, or 45 percent of total expenditures. Figure 1.3 displays the percentage of North Carolinians by race who received Medicaid in 2008. Map 8 (Appendix A, pg. A-10) displays the percent of Medicaid eligibles by county for 2010.

The trend in North Carolina follows the typical age trend of slightly more males under 12 years old and more females in the older age groups. North Carolina has a younger population than other states, ranking 10th in the nation in 2009 for people under 18 years of age. Table 1.1.

Table 1.2 displays the percentages of males and females for the major race/ethnicity categories by North Carolina regions. Race/ethnicity also varies by region with a larger proportion of white non-Hispanics in Western Region, American Indians in Eastern Region, and black non-Hispanics in Eastern Region. A state map showing the N.C regions is displayed on the inside back cover. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 8 Communicable Disease Race/Ethnicity and Gender The racial and ethnic differences of a population play an important role in interpreting gaps in access to health care among the different groups, and these differences are especially true in terms of HIV disease surveillance and intervention. Previous HIV disease surveillance showed that HIV disproportionately affected ethnic minorities in North Carolina. North Carolina has the 18th largest non-white population in the United States (3,058,647 in year 2009) and there are noticeable variations in the demographic composition of North Carolina from region to region. Usually, non-white minorities have poorer health conditions and less access to health care. In 2009, 14 counties had populations consisting of more than 50 percent non-white residents (Robeson: 71.0%; Hertford: 65.1%; Bertie: 64.9%; Edgecombe: 61.6%; Warren: 61.4%; Northampton: 59.8%; Halifax: 59.4%; Vance: 56.9 %; Hoke: 55.8%; Washington: 55.0%; Durham: 54.2%; Greene: 53.6%; Anson: 51.3% and Scotland: 50.7%). Maps 3-6 (Appendix A, pp.A-5 to A-8) display the racial and ethnic make-up of North Carolina’s counties, as reported in the 2009 bridged-race estimates (please see Appendix C, pg. C-5 for more information about Census data and the bridged-race categories used to calculate rates). Table 1.3 displays the populations for the major race/ethnicity categories in North Carolina according to the bridged-race estimates for 2009. Table 1.2.

According to the N.C. Health Profile 2009, compared to whites, blacks have higher death rates from heart disease, cancer, HIV, diabetes, homicide, and stroke. North Carolina has seven counties in which blacks comprise more than 50 percent of the total population (Bertie 62.9 %, Hertford 61.3%, Northampton 57.9%, Edgecombe 56.4%, Halifax 53.8%, and Warren County 53.0%). Map 3 (Appendix A, pg. A-5) displays the proportion of black population in 2009 by county. Hispanics From 2002 to 2009, the estimated Hispanic/Latino population in North Carolina increased by 59.1 percent, from 451,095 to 717,662. Hispanics represented 7.7 percent of the population of the state and ranked 26th nationally. North Carolina ranked 10th in Hispanic births in 2008. Compared to other ethnic groups in North Carolina, Hispanics are a relatively young population. Although the median age of the non-Hispanic population is 38.3 years, the median age of Hispanics is 23.7 years. Seventy percent (70%) of Hispanics are under 35 years old, while only 46 percent of the non-Hispanic population is under 35. Map 5 (Appendix A, pg. A-7) displays the proportion of the Hispanic population in 2009 by county. In North Carolina, Duplin County had the highest proportion of Hispanic residents (22.0%), followed by Sampson County (17.0%), Lee County (17.0%), and Montgomery County (16.5%). American Indians American Indians represent 1.2 percent of the N.C. population and are one of the largest American Indian populations in the United States. About 45 percent of American Indians in North Carolina live in Robeson County, followed by Cumberland, Hoke, Mecklenburg, Wake, Jackson, and Scotland counties. Map 4 (Appendix A, pg. A-6) displays the proportion of Hispanic population in 2009 by county. The 2009 N.C. Health Profile shows that American Indians experience higher death rates due to heart disease, stroke, homicide, diabetes, kidney disease, and unintentional motor vehicle injuries compared to the white population. Foreign-born Population According to the Center for Immigration Studies, North Carolina has experienced a dramatic increase in its immigrant population. The immigrant population in North Carolina has increased three and one-half times between 1995 and 2007 (Camarota, 2007). According to the U.S. Census Bureau’s Annual American Community Survey, North Carolina’s foreign-born population increased by 38 percent from 2002 to 2008 (480,248 to 665,270). In 2006, North Carolina ranked 15th nationally for the admitted number of immigrants from other countries. In 2009, 30.6 percent of the foreign-born populations in North Carolina were naturalized citizens, while 69.4 percent were not citizens. The various regions of birth are displayed in Table 1.4. The majority (57.3%) of the foreign-born population comes from Latin America, with the other 22.2 percent from Asia, 11.7 percent from Europe, 5.7 percent from Africa, 2.7 percent from North America, and 0.5 percent from Oceania. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 10 Communicable Disease The majority of the 2009 foreign-born population was male (52.8%) as opposed to female (47.2%). A majority (50%) of the foreign-born population is between ages 25 to 44 years (Table 1.5). About 83 percent speak a language other than English at home and 50 percent do not speak English “very well.” Table 1.3.

These areas are collectively referred to as Core Based Statistical Areas (CBSAs), with a metro area containing a core urban area of 50,000 or more population, and a micro area containing an urban core of at least 10,000 (but less than 50,000) population (U.S. Census Bureau, Population Division). A complete listing of all micropolitan, metropolitan, and combined statistical areas can be obtained at the following website: http://www.census.gov/population/metro/data/metrodef.html. In the HIV/AIDS Surveillance Supplemental Report, Volume 13 Number 2, the Centers for Disease Control and Prevention (CDC) divides metropolitan areas into large (population greater than or equal to 500,000) and medium-sized metropolitan areas (population 50,000 to 499,999), which are all defined as urban areas. Areas other than metropolitan areas (including micropolitan and non-metropolitan areas) are defined as rural areas. Eleven North Carolina counties, including Anson, Cabarrus, Franklin, Gaston, Guilford, Johnston, Mecklenburg, Randolph, Rockingham, Union and Wake County, are classified as large metropolitan areas, while other metropolitan counties are classified as medium-sized metropolitan areas. About 35 percent of the N.C. population resides in large metropolitan areas, 35 percent in medium-sized metropolitan areas, 22 percent in micropolitan areas, and 8 percent in non-metropolitan areas in 2009. Asian and Pacific Islanders have the highest proportion (56.7%) living in the large metropolitan areas, followed by Hispanics (42.9%). Similar proportions (around 34%) of all race/ethnic groups, except American Indians (18.0%), live in medium-sized metropolitan areas. Data from the U.S. Census showed that in 2006, 65 percent of the general population of the United States was living in large metropolitan areas, 19 percent in medium-size metropolitan areas, and 17 percent in areas other than metropolitan, i.e. rural areas. Compared to national NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 12 Communicable Disease figures, North Carolina has less people in urban areas, substantially less in large metropolitan areas, and more people in rural areas. In North Carolina, a majority of Asians (88%) live in urban areas, followed by Hispanics (76%) and blacks (72%). A majority of American Indians (69%) live in rural areas (Tables 1.6 and 1.7). North Carolina’s metropolitan and non-metropolitan counties are displayed in Map 2 (Appendix A, pg. A-4). Table 1.6.

HEALTH INDICATORS Poverty and Income Contextual factors such as poverty, income, and education, as well as racial segregation, discrimination, and incarceration rates influence sexual behavior and sexual networks. These NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 13 Communicable Disease factors likely contribute substantially to the persistence of marked racial disparities in rates of STDs (Adimora and Schoenbach 2005). According to the U.S. Department of Commerce’s Bureau of Economic Analysis, the 2010 per capita income for North Carolina is $35,638, or 87.8 percent of the national average of $40,584. This figure represents a 2.5 percent decrease from 2009 and placed North Carolina 37th in the nation for personal per capita income and 4th in the Southeast. The economic recession has impacted North Carolina more than the national average. According to the Bureau of Labor Statistics, the unemployment rate in North Carolina rose from 5.0 percent in January 2008 to 8.5 percent in December 2008 to 11.3 percent in December 2009, but went down slightly to 9.8 percent in December 2010. These rates are all higher than the national unemployment rate (the national unemployment rate was 5.0 percent in January 2008 to 7.3 percent in December 2008 to 9.9 percent in December 2009 and to 9.4 percent in December 2010) (Bureau of Labor Statistics). According to Income, Earnings, and Poverty Data from the 2009 American Community Survey, 16.3 percent of North Carolinians were living under the poverty line (while 14.3% nationally). From 2008 to 2009, 19.7 percent of North Carolinians were below the federal poverty level (FPL); with an overall total of 39.9 percent of the population considered low income (199% or below FPL). The median household income in North Carolina was $43,674, a figure much lower than the national median of $50,221. North Carolina ranked 14th in percentage of people in poverty in 2009. Table 1.8 displays the individual poverty rate by age group for the state (2008– 2009) and the nation (2009). Table 1.9 displays the individual poverty rate by race/ethnicity for North Carolina and the United States (2008–2009). Map 7 (Appendix A, pg. A-9) displays the N.C. per capita income for 2009 by county. Health Insurance The percentage of the non-elderly without health insurance in North Carolina has been increasing over the years. In North Carolina (2008–2009), 23 percent of persons ages 19 to 64 years were uninsured (statehealthfacts.org. Kaiser Family Foundation). According to statehealthfacts.org, 39 percent of the non-elderly (0–64 year olds) uninsured had incomes less than 100 percent of the Federal Poverty Guidelines. Table 1.8.

The racial distribution of non-elderly uninsured people in North Carolina is displayed in Figure 1.1. Figure 1.2 displays the uninsured rates by race/ethnicity for North Carolina as compared to the United States. In 2008 to 2009, 47 percent of Latinos or Hispanics, 22 percent of blacks, 13 percent of whites, and 25 percent of other races were uninsured in North Carolina (statehealthfacts.org. Kaiser Family Foundation). Rates of uninsured among all racial/ethnic groups in North Carolina were higher than those in the nation. Although whites comprise the greatest proportion of the uninsured population (Figure 1.1), minorities have the highest uninsured rates (Figure 1.2). Hispanics in North Carolina are more likely to be uninsured because they are often recent immigrants with low-wage jobs in industries that do not offer health insurance. Table 1.9.

Around 5 percent of high school students (grades 9–12) dropped out during the 2008 to 2009 school year (N.C. Public Schools Statistical Profile, 2010). Internet access The internet has become one of the most important venues for health education. In 2007, North Carolina ranked 42nd for the percentage of households with computers (57.7%), and 40th for the percentage of households with internet access (56.8%). Public Aid Total Medicaid and Medicaid-related expenditures in North Carolina for State Fiscal Year (SFY) 2008 were approximately $9 billion for approximately 1.7 million Medicaid recipients (an average $5,262 per recipient). The number of Medicaid recipients increased by 2.6 percent from 2007 to 2008. A total of 1,726,412 North Carolinians, or 18.7 percent of the total N.C. population, received at least one Medicaid service during the 2008 fiscal year (N.C. Medicaid Report 2008). Among them, 40 percent were male and 60 percent were female. Elderly and Disabled recipients comprised about 13.1 and 15.5 percent of total Medicaid recipients, respectively, and their expenditures amounted to $6.2 billion or 65 percent of the total service expenditures. Families and Children comprised 70 percent of all recipients, accounting for $3 billion or about 34 percent of total service expenditures. Aliens and Refugees represented 1.3 percent of all recipients and accounted for about $67.8 million, or about 0.8 percent of total service expenditures. Of all Medicaid services provided, Nursing Facility, Inpatient Hospital, Prescription Drug, and Non-Physician Practitioner services were the top four expensive services and accounted for about $4 billion, or 45 percent of total expenditures. Figure 1.3 displays the percentage of North Carolinians by race who received Medicaid in 2008. Map 8 (Appendix A, pg. A-10) displays the percent of Medicaid eligibles by county for 2010.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 17 Communicable Disease CHAPTER 2: SCOPE OF THE HIV DISEASE EPIDEMIC IN NORTH CAROLINA HIGHLIGHTS As of December 31, 2010, the cumulative number of individuals in North Carolina diagnosed with HIV infection was 38,397 people. An estimated 35,000 people were living with HIV/AIDS in North Carolina (including 7,000 individuals who may have been unaware of their infections) as of December 31, 2010. The total number of new HIV diagnoses in 2010 was 1,487 (15.9 per 100,000 population) and the number of new diagnoses of HIV infection among adults/adolescents was 1,482 (19.2 per 100,000 adult/adolescent population). In 2010, the rate of new HIV diagnoses for adult/adolescent blacks (59.7 per 100,000) was more than 10 times greater than that for adult/adolescent whites (5.6 per 100,000). The rate of new HIV diagnosis for adult/adolescent Hispanics (24.7 per 100,000) was more than four times greater than for whites. The highest rate of new HIV diagnoses in 2010 was among adult/adolescent, black males (94.0 per 100,000). This rate was eight times greater than the rate for adult/adolescent white males (11.6 per 100,000). The rate of new HIV diagnoses for adult/adolescent Hispanic males (35.5 per 100,000) was three times the rate among white males. The largest disparity in 2010 was for adult/adolescent black females; with a rate of new HIV diagnoses (30.5 per 100,000) that was nearly 17 times higher than that of white females (1.8 per 100,000). The rate among Hispanic adult/adolescent females (10.0 per 100,000) was more than five times the rate among white females. For 2010 adult/adolescent HIV disease cases, men who have sex with men (MSM) was the risk category in an estimated 57 percent of total cases, heterosexual transmission risk was estimated in 39 percent, and IDU was estimated in 4 percent of total cases (including 1 percent among MSM who also indicated injection drug use). In 2010, MSM (including MSM/IDU) accounted for 76 percent of new HIV disease cases among adult/adolescent males. In 2010, heterosexual contact accounted for about 95 percent and injecting drug use accounted for 5 percent of HIV disease cases for adult/adolescent females. Twenty percent (20%) of newly diagnosed HIV disease cases in 2010 were among adolescent males ages 13 to 24 years old. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 18 Communicable Disease In 2010, 26.0 percent of newly diagnosed HIV disease cases also represented new AIDS cases (i.e., HIV and AIDS diagnosed at the same time or within six months). Mecklenburg County had the most HIV cases diagnosed in 2010 (n=312), followed by Wake County (n=172) and Guilford County (n=118). In 2010, Edgecombe County had the highest three-year average HIV disease rate (41.0 per 100,000), followed by Mecklenburg County (38.1 per 100,000), Durham County (33.7 per 100,000), Northampton County (31.2 per 100,000), Wilson County (29.0 per 100,000), and Guilford County (27.5 per 100,000). In 2010, HIV/AIDS was listed as the 7th leading cause of death for N.C. adults from 25 to 44 years old. The crude HIV disease death rate for blacks is more than 13 times higher than for whites (12.1 vs. 0.9 per 100,000). From the beginning of the epidemic through December 2010 (1983–2010), 19,761 AIDS cases have been reported in North Carolina North Carolina ranked 11th among the 50 states in AIDS cases diagnosed in 2009 (the most recent year available for national comparisons) and 13th in the nation in 2008 for estimated persons living with AIDS. Seven hundred ninety-six AIDS cases were diagnosed in North Carolina in 2010 (8.5 per 100,000 population). Special notes: HIV disease includes all initial diagnoses of HIV as well as those diagnosed with AIDS as their initial diagnosis. More information about this designation of HIV disease can be found in Appendix C (pg. C-3). The HIV disease and AIDS case totals and rates presented in the demographic tables (See Appendix D: Tables A–H, O–P) and discussed in this document are restricted to adults/adolescents only for comparability across states and with national data reported by the Centers for Disease Control and Prevention (CDC). All county totals and references to cumulative cases and persons living with HIV/AIDS do include the 0 to 12 age group. Unless otherwise noted, year refers to year of diagnosis, not year of report, as in previous publications. Unless otherwise noted, references to all racial groups in surveillance data are presented in a race/ethnic designation. Hispanics are considered a separate racial/ethnic group. Thus, “white” refers to white non-Hispanics; “black” refers to black non-Hispanics, etc. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 19 Communicable Disease OVERALL HIV DISEASE TRENDS Figure 2.1 displays the number of HIV disease cases diagnosed from 1992 to 2010 by the year of HIV diagnosis for the individual. New diagnoses for 2010 reflect a continuation of the decline seen in 2009 and the lowest number of new cases diagnosed since the year 2000. The highest point in the HIV epidemic occurred in 1992 in North Carolina with 2,202 cases diagnosed and then moderated from 1995 to 2010 with an average of 1,600 cases (range: 1,400–1,800) each year. The number of HIV disease cases diagnosed in 1992 represented a time when HIV incidence was likely at its peak. From 1995 to 2010, the epidemic was relatively stable; however, changes in reporting practices contributed to the fluctuations during this period, especially for 2002. The increase in cases in 2007 and 2008 was at least partially a result of Communicable Disease Branch efforts to increase HIV testing, including the Get Real. Get Tested campaign, and might not necessarily represent increased incidence. The fact that a decrease was seen in 2009 and further in 2010 might be evidence of a true decline in incidence; however, only additional years of data will determine whether this is actually the case.

Information about persons living with HIV disease is very critical for case follow-up, AIDS care provision, and strategic intervention and testing activities. From the first HIV disease case diagnosed and reported to the Division of Public Health in 1983, through December 31, 2010, the cumulative number of HIV disease cases diagnosed in North Carolina is 38,397, of whom 25,074 are living and 13,323 have died. This number includes some HIV-positive individuals that died of non AIDS-related causes (see pg. 49 for HIV disease related deaths). Figure 2.2 displays the numbers of people living with HIV disease, which represent prevalent cases at the end of each year from 2006 to 2010. The number of people living with HIV disease has been increasing every year, indicating that the number of newly diagnosed HIV disease cases exceeds the number of people who died. Due to the advancement of highly effective anti-retroviral treatment and opportunistic infection control, people with HIV disease may live longer and healthier lives. Persons living with HIV represent individuals that have been diagnosed and subsequently reported to the North Carolina public health surveillance system. Case counts are affected by some amount of under-reporting by clinicians as well as people who are infected with HIV but have not been tested and reported. Efforts to identify the unaware positive population will increase new diagnoses in the future. However, the current number of total living cases in Figure 2.2 under-represents true HIV prevalence and must be adjusted to account for those who have been diagnosed but not reported and those who are unaware of their status. One method for estimating people who are unaware they are HIV positive is based on the CDC estimate that 80 percent of people living with HIV have been tested and know their status. Studies indicate that the N.C. HIV surveillance system currently captures 85 to 95 percent of HIV diagnoses (Appendix B, pg. B-3). Applying these two statistics to our current surveillance total of 25,074 people living in North Carolina with HIV/AIDS increases the estimated HIV disease prevalence in the state to approximately 35,000 people. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 21 Communicable Disease Please note HIV disease reports are periodically updated with vital status data available from the State Center for Health Statistics, thus “living totals” for earlier years, especially for the last two years, have been revised. Demographics of Persons Living with HIV Disease Gender, race/ethnicity, and age distribution Table 2.1 and Table J (Appendix D, pg. D-13) display the demographics of people living with HIV disease as of December 31, 2010. Male prevalent cases were 70 percent of the total and more than double the female prevalence. Blacks comprised the majority (66%) of cases, followed by whites (26%) and Hispanics (6%). Older individuals represented a larger percentage of people living with HIV, as people can live for many years on HAART (Highly Active AntiRetroviral Treatment) with an HIV diagnosis. The greater percentages of males (70%) and blacks (66%) living with HIV disease indicates that these groups are most affected by the HIV epidemic in North Carolina. Table 2.1.

Table I (Appendix D, pg. D-12) shows that 46 percent of living cases were likely infected through MSM activities, 38 percent through heterosexual transmission, 11 percent through injection drug use practices (IDU), and 3 percent through MSM/IDU activities. NEWLY DIAGNOSED HIV DISEASE CASES IN 2010 In 2010, 1,487 (15.9 per 100,000) individuals were newly diagnosed with HIV infection in North Carolina. Of the newly diagnosed persons, 1,482 of them were over 13 years old, which makes the rate of HIV infection among adults/adolescents 19.2 per 100,000 (Table 2.2.). Gender and race/ethnicity Among individuals diagnosed with HIV disease in 2010, about three times as many were male compared to female. Table 2.2 displays the gender and race/ethnicity distribution of newly diagnosed HIV disease among adults/adolescents for 2010. Among the adult/adolescent population newly diagnosed with HIV disease in 2010, blacks made up the majority of cases (65.7%), followed by whites (23.9%), and Hispanics (7.8%). Over the previous five years (2006–2010), blacks have consisted of about 65 percent, whites 26 percent, and Hispanics around 8 percent of total cases, as shown in Figure 2.3 and Table B (Appendix D, pg. D-5). HIV disease rates are different from the proportion of HIV cases because rates take into account the race/ethnicity of the state’s population. The highest rate of newly diagnosed HIV disease was among black males (94.0 per 100,000 adult/adolescent population), which was eight times that for white males (11.6 per 100,000 adult/adolescent population). The HIV disease rate among adult/adolescent black females (30.5 per 100,000 adult/adolescent population) was nearly 17 times higher than the rate for adult/adolescent white females (1.8 per 100,000), which represented the largest disparity noted within gender and race/ethnicity categories.

Adult/adolescent HIV disease rates by race/ethnicity and gender, 2006–2010 Disparities also existed for Hispanics as compared to whites. The rate for adult/adolescent Hispanic men (35.5 per 100,000) was more than three times the rate for white men, and Hispanic males ranked second highest among the gender and race/ethnicity rates. The rate for adult/adolescent Hispanic women (10.0 per 100,000) was more than five times that for white women. Rates for other racial/ethnic groups are based on numbers too small for meaningful comparisons but are displayed in Table 2.2. Figure 2.3 shows that the proportions of racial composition of HIV disease cases remained stable over the last five years, and blacks have consistently represented over 60 percent of HIV disease cases. Figure 2.4 shows the gender and race/ethnicity (for whites, blacks, and Hispanics) specific HIV disease rates. From 2006 to 2010, HIV disease rates for black males have increased slightly while the rates for black females, Hispanic females, and white men have decreased slightly. 0% 10% 20% 30% 40% 50% 60% 70% 2006 2007 2008 2009 2010 Proportion White* Black* Hispanic 0 20 40 60 80 100 120 2005 2006 2007 2008 2009 Rate per 100,000 White* male White* female Black* male Black* female Hispanic male Hispanic female Figure 2.3.

Overall, adults ages 20 to 29 years and 40 to 49 years accounted for the greatest proportion (about 54% together) of individuals diagnosed in 2010 (Table 2.3). Figure 2.5 displays the difference of ages between males and females diagnosed with HIV disease in 2010. More males between ages 20 to 29 years (20%) were diagnosed, while proportionately more females between ages 35 to 39 years (16%) and 45 to 49 years (16%) were diagnosed. The difference of ages at diagnosis reflects the difference in risk for male and females. In recent years, HIV disease has been increasing among young black men in North Carolina, unlike previous years, when the HIV epidemic was increasing primarily among an older population. Table 2.3.

Interviewing the patient, the sex and/or drug-using partners, and the treating physician are all methods used to determine risk factors. Ultimately, each case is assigned to one primary risk category based on a hierarchy of disease transmission developed by the CDC and others. Table 2.4 displays the mode of transmission for adult/adolescent HIV disease cases diagnosed in 2010. The principal risk categories were: men who have sex with men (MSM), injection drug use (IDU), and heterosexual sex. The proportion of cases for which there was no identified risk (NIR) reported was substantial (38%). A portion of these NIR cases were classified as NIR not due to missing or incomplete information, but rather because the reported risk(s) did not meet one of the CDC-defined risk classifications; this was especially common for the heterosexual risk category. Meeting the CDC-defined risk of heterosexual transmission includes the requirement of knowing a partner’s risk (sex with known MSM or IDU, or sex with known HIV-positive person). Consequently, some NIR cases have been reevaluated and reassigned to a “presumed heterosexual” risk category based on additional information gathered from follow-up interviews with newly diagnosed individuals (such as the exchange of sex for drugs or money, previous diagnoses with other STDs, or multiple sexual partners). Even with the reassignment of presumed heterosexual risk for some NIR cases, a substantial proportion (24%) of cases remained assigned as no identified risk. 0% 5% 10% 15% 20% 13-14 15-19 20-24 25-29 30-34 35-39 40-44 45-49 50-54 55-59 60-64 65+ Male 0% 5% 10% 15% 20% 13-14 15-19 20-24 25-29 30-34 35-39 40-44 45-49 50-54 55-59 60-64 65+ Female Figure 2.5.

Over the period of 2006 to 2010, MSM have been the leading mode of transmission, increasing from 50 percent in 2006 to 57 percent in 2010 (14% increase). During the same time period, IDU (including MSM/IDU) transmission decreased 43 percent and heterosexual transmission decreased 9 percent. Table 2.5.

Table 2.5 shows that in 2010, MSM were estimated to represent about 57 percent of all HIV disease cases. Heterosexual transmission risk represented about 39 percent of all HIV disease cases and IDU and MSM/IDU (men who have sex with men and inject drugs) represented about 4 percent (including MSM/IDU). More explanation of this general risk reassignment of NIR cases can be found in Appendix C (pg. C-4). In addition, the redistributed risk assignment of NIR cases for all living cases can found in Table I (Appendix D, pg. D-12).

For males, MSM accounted for about 75 percent of HIV disease cases diagnosed in 2010; heterosexual contact cases accounted for about 21 percent of cases; and IDU cases (including MSM/IDU) accounted for about 4 percent.

For males, the proportion of MSM cases has risen in recent years, from 70 percent in 2006 to 75 percent in 2010. The proportion of IDU cases (including MSM/IDU) for males has declined from 6 percent to 4 percent from 2006 through 2010. For females, the proportion of heterosexual contact reports has increased from 91 to 95 percent and proportion of IDU transmission decreased from 9 to 4 percent from 2006 through 2010. Gender, race/ethnicity, and mode of transmission Among white males, MSM represented 87 percent of cases, heterosexual risk represented 8 percent of cases, and IDU risk represented 2 percent of cases. For black males, MSM represented about 72 percent of HIV cases, heterosexual risk represented about 25 percent of cases, and IDU risk (including MSM/IDU) about 4 percent of cases. The risk breakdown for other races/ethnicities (Hispanics, American Indians, and Asian/Pacific Islanders) are grouped together as “All other” because of low case numbers. Within this aggregated group, MSM risk represented 76 percent of male cases, heterosexual risk 34 percent of cases, and IDU risk (including MSM/IDU) 4 percent of cases. The proportions of HIV cases attributed to heterosexual risk among black males (25%) and other races (34%) are higher than the proportion among white males (8%). Although some of this observed difference may be due to underreporting of MSM activity among minority males, some is attributed to the difference in disease prevalence for each racial/ethnic group and the subsequent affect on risk. Unlike the differences in risk observed for males among the racial/ethnic groups, the majority of all HIV cases among females, regardless of race/ethnicity, are attributed to heterosexual sex. IDU is attributed to a greater proportion of white female cases (17%) than to minority females (2–5%; Figures 2.9 and 2.10).

Because there can be significant delay between infection and subsequent testing and reporting, the age group 13 to 24 years better describes infections that likely occurred during adolescence. In 2010, while just 5.5 percent of total cases diagnosed were found among teenagers from 13 to 19 years, the percentage increased to 22.9 percent when 20 to 24 year olds were included. From 2006 to 2010, the proportion of adolescents among HIV disease cases has increased from 15.9 percent to 22.9 percent of all reports. The proportion of cases among each racial group for adolescents is similar to that of HIV cases overall: minorities are disproportionally affected. Examining the race of new adolescent HIV cases 2010 shows that infections were concentrated among blacks for both men (81%) and women (85%; Figures 2.11 and 2.12). Although adolescent cases do not represent the majority of HIV cases diagnosed in each year, adolescence is the critical age for health education and HIV prevention.

In 2010, all new HIV disease cases among adolescent females were attributed to heterosexual contact. For adolescent males, the proportion of HIV disease cases attributed to heterosexual contact was only 6 percent and the proportion attributed to MSM risk accounted for 92 percent, up from the 88 percent of the diagnosed in 2006. As compared to cases for older persons, adolescent cases are more likely to be associated with sexual activity (99% vs. 96%) and not injection drug use practices. Table C (Appendix D, pg.

For this reason, special emphasis is placed on follow-up for known HIV-infected mothers in North Carolina. Table 2.6 displays the proportion of HIV-infected women who were of child-bearing age (15–44 years old). Approximately 300 women of child-bearing age are diagnosed with HIV each year in North Carolina (65% of total female HIV cases). Note that the number and proportion of HIV diagnoses among N.C. females has decreased in recent years. Readers should keep in mind that the delays in testing and diagnosis can significantly affect the assessment of the actual number of females in this category. Table 2.7 displays the numbers of likely perinatal HIV transmissions that have occurred from 2001 to 2010 by year of birth. These numbers represent pediatric reports that indicate likely perinatal transmission based on exposure categories in HIV surveillance data. Since 2007, there have been decreases noted in the number of HIV-positive babies born in North Carolina. Confirming HIV in perinatal cases takes time, so case totals for recent years should be considered preliminary. In November 2007, North Carolina implemented new HIV testing statues that require every pregnant woman be offered HIV testing by her attending physician at her first prenatal visit and in the third trimester. If there is no HIV result test on record during the current pregnancy, the pregnant woman will be tested at labor and delivery and/or the infant will be tested for HIV. HIV DISEASE AMONG FOREIGN-BORN RESIDENTS Information about foreign-born HIV cases is important for planning outreach and prevention initiatives because messages and information must be tailored or designed for the appropriate culture and language.

The number of HIV disease cases identified among foreign-born people in North Carolina (Figure 2.15) has increased in the last eight years. These increases reflect the greater pattern of migration to the state and may indicate better data collection of country of origin in surveillance data. The number of foreign-born HIV disease cases in 2010 (n=93) represented approximately 9 percent of all foreign-born HIV cases (987) for the last 10 years (2001–2010). Table 2.8 shows the race/ethnicity of the foreign-born HIV cases. Hispanics comprised the highest proportion (61.2%). Non-Hispanic blacks comprised 27.5 percent of cases; whites and Asian/PI made up 5.4 and 4.5 percent respectively. Table 2.8.

The majority (63%) of foreign-born HIV disease cases were diagnosed in urban counties including Wake (20%), Mecklenburg (20%), Durham (9%), Guilford (9%), and Forsyth (5%). About 7 percent of foreign-born cases were diagnosed in rural counties, including Duplin, Davidson, Rowan, Hertford, Craven, Robeson, Sampson, and Lee counties. Figure 2.15.

Large and medium-sized metropolitan areas are usually referred to as urban areas, and micropolitan and non-metropolitan areas as rural areas. According to CDC, 79 percent of national AIDS reports are from large metropolitan areas and 13 percent are from medium-sized metropolitan areas, resulting in 92 percent of reports from urban areas and 8 percent from rural areas in 2009. New HIV Diagnoses in Urban/Rural and Metropolitan Areas While 77 percent of new diagnosis in 2010 were from urban areas, (See Table 2.9, Map 9, Appendix A, pg. A-11), some of the highest HIV disease rates (per 100,000 population) are found in rural areas, especially among blacks and Hispanics (See Table 2.13, Map 10, pg. A-12). The HIV disease rate in medium metropolitan areas in 2010 was slightly higher than the rates in micropolitan and non-metropolitan areas (Table 2.10). Figure 2.16.

Edgecombe County ranked highest with an HIV disease three-year average rate of 41.0 per 100,000 population in 2010, followed by Mecklenburg County (38.1), Durham County (33.7), Northampton County (31.2), Wilson County (29.0), and Guilford County (27.5). Readers are cautioned to view rates carefully, as rates based on small numbers (generally less than 20) are considered unreliable. Persons diagnosed in long-term institutions, such as prisons, are removed from county totals for a better comparison of HIV impact among communities. Table 2.10.

More than 50 percent of living cases diagnosed in North Carolina were from seven counties, which included Mecklenburg (17.6%), Wake (10.4%), Guilford (7.4%), Durham (5.8%), Forsyth (4.9%), Cumberland (4.7%), and New Hanover (2.4%) counties. About 75 percent of living HIV cases were in urban areas and 20 percent in rural areas. Roughly, the prevalence rates for blacks and whites were higher in urban than in rural areas (Table 2.11). County of residence is based on where an individual was living when diagnosed with HIV disease. People may move to other areas in the years after diagnosis. Assuming no significant difference between the numbers of HIV disease cases moving in and out of the original residence county, the statistics still indicate roughly the number and rate of living HIV disease cases in the corresponding counties. Although the highest prevalence rates for whites and blacks were in urban (large and medium-sized metropolitan areas), the highest rate for Hispanics was in non-metropolitan areas (Table 2.12). As with new HIV diagnoses in 2010, more American Indian prevalent cases were diagnosed and reported in micropolitan areas, making the rate in that area much higher than the rate in other areas (Table 2.12). The number of prevalent cases for Asian/Pacific Islanders and American Indians/Alaska Natives were still too small to make comparisons, especially in non-metropolitan areas. Table 2.11.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 36 Communicable Disease Physiographic Regions Geographic areas can be defined in many ways. In this HIV/STD Epidemiologic Profile, data are presented in three categories of geographic areas for the convenience of readers: metropolitan areas, rural/urban areas, and physiographic regions. The distribution of HIV disease is uneven across North Carolina, as can be seen in Maps 9 and 10 (Appendix A, pg. A-11 to A-12). Cases are assigned to the county of residence at first diagnosis. This distribution can be partly explained by the population distribution in Map 1 (Appendix A, pg. A-3), as the epidemic tends to be concentrated in urban areas. The North Carolina state demographer and the GIS lab at the State Center for Health Statistics have produced a Geographic Regional Classification scheme based on "physiographic" qualities. According to this scheme, North Carolina has three regions, West Region, Piedmont Region, and East Region (Table 2.16). Western Region includes counties west of (and including) Surry, Wilkes, Caldwell, Burke, and Rutherford; Eastern Region includes everything east of (and including) Northampton, Halifax, Nash, Johnston, Cumberland, Hoke, Harnett, and Scotland. Piedmont Region includes the counties in between the Western Region and the Eastern Region. Table 2.12.

For American Indian/Alaska Natives, most HIV disease cases were diagnosed in the Eastern Region. For Asian/Pacific Islanders, HIV cases were most prominent in the Piedmont Region, while the rate in the Eastern Region is higher than the Piedmont Region because of a smaller Asian/PI population in Eastern Region (Table 2.13). Among the HIV disease cases living through the end of 2010, a majority of whites, blacks, and Hispanics were diagnosed and reported from Piedmont Region (66%), followed by the Eastern Region. Because the American Indian population in the Piedmont Region is smaller than in the Eastern Region, the prevalence rate in the Piedmont Region is higher than the rate in the Eastern Region (Table 2.14). The Western Region had fewer HIV cases and rates for both new diagnoses and prevalent cases in 2010. Table 2.14.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 38 Communicable Disease HIV DISEASE CASES DIAGNOSED LATE Late testers represent a significant proportion of new HIV diagnoses in North Carolina, indicating the need for increased HIV testing and linkage to medical care. People who test late in the course of HIV infection may already have serious HIV-associated complications and are not able to benefit fully from antiretroviral therapy and prophylaxis to prevent opportunistic infections. Late testing also results in missed opportunities for preventing new HIV infections, as knowledge of positive HIV status promotes adoption of safer sex practices (CDC, 2000). The estimated 20 percent of people in the United States who have HIV and do not know it are estimated to account for 54 percent of new transmissions (Marks, 2006). Table 2.15 shows the proportion of individuals diagnosed as AIDS when they were first diagnosed as HIV infected (late HIV diagnosis or concurrent AIDS cases) in 2010. These persons with concurrent diagnosis are generally referred to as “late testers” and include any person who receives an AIDS diagnosis within six months of the initial HIV positive screening. Hispanic males had the highest proportion (43.9%) of late testers, reflecting possible cultural and language barriers to testing and access to care. Overall, 26.0 percent of newly diagnosed individuals had a concurrent AIDS or late HIV diagnosis in 2010, indicating that they probably had HIV for at least five to seven years (CDC, 2006). Hispanic men experienced a much higher proportion of late testers than other racial/ethnic groups, with nearly 44 percent of new infections diagnosed late. This figure represents an increase from the proportion of late testers among Hispanic men in 2009 (36.5%). As shown in Table 2.16, roughly 25 to 30 percent of individuals newly diagnosed with HIV disease each year also represent AIDS cases (i.e. late testers) during the 2006–2010 period. The significant proportions of late diagnoses indicate the need for increased HIV testing within North Carolina. These figures support the recommendation to include voluntary HIV testing as part of routine medical examinations for all U.S. residents ages 13 to 64 years (CDC, 2006). Table 2.17 displays the gender and race specific proportions of all late testers (concurrent AIDS cases) diagnosed from 2006 to 2010. Blacks comprise 57 to 61 percent of total late testers, whites comprise 23 to 27 percent, and Hispanics comprise 10 to 15 percent in the past five years. Table 2.15.

The N.C. Division of Public Health is actively pursuing new policies and guidelines aimed at making HIV testing part of routine medical care settings and continues to work with HIV-infected persons and their partners to reduce transmission. Rapid HIV tests have also created new opportunities to expand HIV testing into nontraditional and high prevalence settings (e.g. emergency rooms, correctional facilities, community settings and mobile testing sites). In addition, specific initiatives such as the statewide Get Real. Get Tested. Campaign have been designed to encourage North Carolinians to get educated about and tested for HIV.

In 2010, the State Laboratory of Public Health performed about 227,038 HIV tests, which represents a 55 percent increase in testing since 2006 when about 146,548 tests were performed (See Chapter 3 for more information about HIV testing in North Carolina). HIV DISEASE STAGING The Centers for Disease Control and Prevention (CDC) uses a new staging system for HIV disease to monitor the epidemic. This staging system is based on CD4+ cell counts as well as the existence of certain HIV-related clinical conditions at the time of diagnosis and is meant to assess the severity of HIV disease. Table 2.18 below shows the current staging definitions used by the CDC. The nine mutually exclusive categories allow clinicians and epidemiologists to view HIV disease on a spectrum, ranging from acute HIV infection (A1) to advanced AIDS (C3). In order to properly stage HIV infection using these new categories, it will be important to increase CD-4 reporting in North Carolina. Table 2.18.

THE IMPACT OF AIDS IN NORTH CAROLINA All 50 states, the District of Columbia, and the U.S. dependent areas report AIDS cases to the Centers for Disease Control and Prevention (CDC) by using a uniform surveillance case definition and a case report form. For persons with laboratory-confirmed HIV infection, AIDS cases represent individuals with CD4+ T-lymphocyte percentages of less than 14 or CD4+ T-lymphocyte counts of fewer than 200 cells/μL or the presence of one of 23 clinical conditions indicating an impaired immune system. The date of AIDS diagnosis represents the date that an individual is diagnosed with AIDS based on the above case definition. Ideally, individuals are diagnosed with HIV infection long before they are diagnosed with AIDS. In North Carolina, however, 49 percent of 2010 AIDS diagnoses were made at the same time or within six months of HIV diagnoses. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 41 Communicable Disease Monitoring cases that transition from HIV to AIDS in North Carolina provides both a valuable measure of the continuing efficacy of treatment and also indicates which patients may not have access to care. Increases in AIDS diagnoses have several implications. First, these increases may indicate that more HIV-infected individuals are being tested and reported in North Carolina. Another possible implication is that HIV-infected (status aware) individuals are not receiving proper medical care. Finally, increases in AIDS diagnoses may suggest that current treatments are no longer as effective or patients are not adherent to their HIV drug regimes. Because changes in AIDS cases and rates may indicate changes in the anticipated care needs, agencies that provide medical care and support services to persons living with HIV/AIDS should closely monitor cases. NORTH CAROLINA AND THE U.S. All states have name-based AIDS case reporting by law and provide data that are acceptable for state–to–state and state–to–U.S. comparisons. Comparing North Carolina to the nation is limited to earlier years because national surveillance data is released later than state data. According to the Centers for Disease Control and Prevention (CDC), the national AIDS case rate in 2009 was 11.2 per 100,000 population (CDC, HIV/AIDS Surveillance Report, 2009). During the same time period, North Carolina’s AIDS case rate was 11.6 per 100,000 population. North Carolina ranked 9th among all states and the District of Columbia in the number of new AIDS cases reported (Table 2.19). Please note that comparisons made between other states, North Carolina, and the U.S. are based on counts and rates calculated by the CDC and have been statistically adjusted for delays in reporting; these numbers may differ slightly from North Carolina’s unadjusted case counts and rates. The impact of HIV/AIDS in the South is a growing concern. In 2009, the South had 49 percent of new AIDS cases overall, including five of the top 10 states reporting the most AIDS cases (Table 2.19). The South also had the highest regional rate in 2009 (13.9 per 100,000). In 2009, seven of the top 10 states by AIDS case rate were in the South (Top 10: DC, NY, FL, MD, LA, Puerto Rico, DE, NJ, SC, and GA); Mississippi (11th) and North Carolina (12th) followed.

Table 2.20 displays HIV disease prevalence in North Carolina by HIV disease stage (HIV/AIDS), demographic characteristics, and transmission categories. AIDS cases were notably higher (proportionately) than HIV (non AIDS) cases for males, Hispanics, injection drug users (IDU), heterosexuals (CDC defined), and persons ages 45 years and older. Sixty seven percent (67%) of both AIDS and HIV (non AIDS) cases were among blacks in North Carolina. North Carolina ranked 7th in the nation and D.C. for the percentage of all AIDS cases among blacks in 2007 (CDC special request, 2/2010). Table 2.20.

In 2010, 796 new AIDS cases were diagnosed in North Carolina with a rate of 8.5 per 100,000 population (10.3 per 100,000 adult/adolescent population). Most subpopulations in North Carolina have experienced stable or decreasing rates of AIDS. Particularly large decreases were seen among black males ages 35-39 (63% decrease; from 68 cases in 2006 to 25 cases in 2010), black males ages 40 to 44 (45% decrease; from 74 cases in 2006 to 41 cases in 2010) and Hispanic males ages 25 to 29 (67% decrease; from 15 in 2006 to 5 in 2010). However, over the past five years, AIDS cases have increased 60 percent among white males ages 45 to 49 (from 28 cases in 2006 to 45 cases in 2010) and 50 percent among white males ages 50 to 54 (from 16 cases in 2006 to 24 cases in 2010). Although AIDS cases among females have generally decreased over the past five years, increases were observed among younger black females ages 20 to 24 (67% increase; from 6 cases in 2006 to 10 cases in 2010) as well as older black females ages 60 to 64 (200% increase; from 5 cases in 2006 to 15 cases in 2010) and black females age 65 years and older (300% increase; from 2 cases in 2006 to 8 cases in 2010). The number of AIDS cases among American Indians has decreased over the past five years to a minimum of three cases in 2010. Asians experienced a return to pre-2009 levels with three AIDS cases in 2010. AIDS IMPACT ON RACIAL AND ETHNIC MINORITIES As observed for HIV disease, racial and ethnic minorities continue to be disproportionately affected by the AIDS epidemic in North Carolina (Figure 2.17). Blacks account for a disproportionate share of AIDS cases, relative to their size in the population of North Carolina. Figure 2.17.

The disparity between blacks and whites is slightly greater for AIDS than for HIV disease in North Carolina. The AIDS rate among blacks is nearly 10 times higher than for whites while the rate for HIV disease is nine times higher among blacks than whites. In 2010, black males represented 60 percent of all adult/adolescent male AIDS cases and the AIDS rate among adult/adolescent black men (45.7 per 100,000) was 7.5 times the rate for white men in 2010 (6.1 per 100,000). Hispanics represented six percent of all 2010 AIDS cases and the AIDS rate among Hispanic males (18.7 per 100,000 adult/adolescent population) was 3.1 times higher than for whites (Figure 2.18).

Latinas represented three percent of female AIDS cases in 2010 and the AIDS rate among Latinas (3.0 per 100,000) was almost more than three times the rate among white women (Figure 2.19). TREATMENT The lifetime cost of treating HIV disease is approximately $367,000 (CDC, 2010). Identifying HIV infected individuals early in the course of disease and linking those individuals to medical care extends life expectancy, reduces medical costs, and reduces the spread of HIV to others. Current treatment for HIV infection consists of highly active antiretroviral therapy (HAART). Without treatment, progression from HIV infection to AIDS has been observed to occur at a median of between nine to ten years with the median survival time after developing AIDS only 9.2 months (Morgan, 2002). Since the mid 1990s and the introduction of antiretroviral drugs to combat the progression of HIV disease, increases in the length of time between HIV and AIDS diagnosis have been observed in North Carolina surveillance data, generally indicating an improvement in health status and access to care for many HIV infected persons (Figure 2.20). *Average excludes late testers or persons with an AIDS diagnosis within six months of their initial HIV diagnoses Figure 2.20.

HAART does not cure the patient of HIV, nor does it remove all symptoms. If treatment is stopped, high levels of HIV-1 virus return, and may be anti-retroviral drug resistant (Dybul, 2002). Non-adherence to antiretroviral therapy is the major reason individuals fail to benefit from HAART (Becker, 2002). The reasons for non-adherence with HAART are varied and include: poor access to medical care, inadequate social supports, psychiatric disease, and drug abuse (Nieuwkerk, 2001). The complexity of HAART regimens, whether due to pill number, dosing frequency, meal restrictions or side effects of the medication, contribute to the problem of intentional non-adherence (Heath, 2002). Although antiretroviral therapy frequently improves quality of life among symptomatic patients, antiretrovirals may also be associated with reduced quality of life in asymptomatic patients. Adverse effects, including nausea, vomiting, diarrhea, and abdominal pain, as well as the inconvenience of taking medication every day, may outweigh the overall benefit in some patients. As a result, the patient may decide to delay therapy whenever possible. Known complications related to cumulative use of antiretroviral drugs include increased incidence of cardiovascular disease, loss of bone density, loss of subcutaneous fat, the accumulation of fat in some parts of the body, and insulin resistance (DHHS, 2009; Montessori, 2004). SURVIVAL In North Carolina, survival (the estimated proportion of persons surviving a given length of time after diagnosis) increased with the year of diagnosis for HIV diagnoses made during 2001 to 2005, although year-to-year differences were small. Survival decreased as age increased, particularly among the 65+ age group. Survival was greatest for persons ages under 13 and ages 13 to 24 and lowest among the ages 65+ group. Survival was greater among Asians and Hispanics than among blacks, American Indians, and whites (Table 2.21). Survival was greater among MSM and lowest among females who were injecting drug users (IDU). Vital status may not be determined or reported for all cases, however, the reporting of deaths for persons reported as having AIDS is estimated to be more than 90 percent complete.

The North Carolina State Center for Health Statistics reported 321 HIV/AIDS deaths in 2010 (3.4 per 100,000) (Table 2.22). Together with 1,095 deaths occurring from 2007-2009, the total number of deaths caused by HIV disease in North Carolina through 2010 is 11,837 (different from the total number of deaths for persons infected with HIV/AIDS mentioned in pg. 20). Unlike chronic diseases with high death rates among older populations (such as cancer or cardiovascular diseases), HIV/AIDS death rates are concentrated among young and middle-aged people. According to the State Center for Health Statistics, the crude death rate is about 13 times higher for blacks (12.1 per 100,000) than for whites (0.9 per 100,000). Advances in treatment of HIV with antiretrovirals (ARVs) have been reflected with a major increase in life expectancy for people diagnosed with HIV infection. Between 1996 and 2005, average life expectancy after HIV diagnosis increased from 10.5 to 22.5 years (Harrison, 2010). Despite advances in combating HIV, eventually most HIV-infected individuals develop AIDS. However, individuals diagnosed with AIDS have also seen increases in life expectancy: among individuals diagnosed with HIV having an initial CD4 count of <200 or a CD4 count of <200 within 6 months of their initial diagnosis, the average survival time had nearly quadrupled from 1996 to 2005 (5.5 years in 1996 to 19.4 years in 2005; Harrison, 2010). Patients with AIDS mostly die from opportunistic infections or malignancies associated with the progressive failure of the immune system. The age adjusted death rate for HIV disease in North Carolina for 2008 (the last year of data for national comparisons) was 4.2 per 100,000 (the U.S. death rate was 5.3 per 100,000) (CDC, 2011). HIV Disease is a leading cause of death among younger individuals ages 25 to 64 and varies by race/ethnicity in North Carolina (Table 2.23). According to North Carolina’s State Center for Health Statistics (SCHS, 2011), in 2009, HIV disease was the 3rd leading cause of death among black females ages 25 to 44 (n=46 deaths) and the 5th leading cause of death among black males of the same age (n=53 deaths). HIV disease was the 7th leading cause of death among Hispanic males ages 25 to 44 in 2009 (n=10 deaths) and HIV was not listed in the top 10 leading cause of death among Hispanic females of the same age. HIV disease was not listed among the top 10 causes of death among white males or females ages 25 to 44 in 2009. HIV disease was the 8th leading cause of death among American Indian males ages 25 to 44 in 2009 (n=1) and was not a leading cause of death among American Indian females of the same age.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 3 NC DHHS 51 Communicable Disease CHAPTER 3: HIV TESTING AND PREVENTION INNORTH CAROLINA HIGHLIGHTS Since November 2002, 176 people have been identified with acute HIV infection by the N.C. State Lab of Public Health (N.C. SLPH). Acute HIV infection refers to the very early, particularly infectious stages of HIV infection. The diagnosis of acute HIV provides an opportunity for early linkage to HIV care and helps reduce potential HIV transmission by newly infected patients. In 2010, 24 acute infections were detected by N.C. SLPH. In 2010, a total of 246,458 persons were tested through state-sponsored HIV testing programs. Of those tested, 1,103 were positive (501 new cases, 546 previous positives, and 56 unknown). In 2010, 49 percent (n=244) of all new HIV cases were found through testing done at STD clinics, where a majority of the testing takes place. New case positivity rates were highest for testing done through partner counseling and referral services (5.7%). HIV positivity rates were also elevated for those tested in HIV test sites (usually nontraditional testing sites, 0.9% positivity), and community health sites (0.5%). In 2010, 69 percent of those tested were female and 30.7 percent were male. Positivity rates were higher for males (0.55%) compared to females (0.06%). Overall, 44 percent of those tested for HIV in 2010 were black non-Hispanic, 27.5 percent were white non-Hispanic, 18.1 percent Hispanic, 1 percent American Indian, 1.1 percent Asian/Pacific Islanders, and 0.1 percent other race/ mixed race . HIV positivity rates were highest for males in the other/mixed race group (1.25%) followed by black non-Hispanic males (0.67%). The disparity was greatest among women. In 2010, the HIV positivity rate for black non-Hispanic women (0.31%) was 2.6 times the rate for white women (0.12%). In 2010, the largest number of new HIV cases was found in the group with the most tests (age 20-29 years, n=250 cases). Overall the highest positivity rates were seen among those 40 years and older (0.29%). The highest new positivity rates in 2010 were among those in the MSM (3.7%) and MSM/IDU (1.0%). The highest new HIV positivity for women was among those with heterosexual high risk (0.13%). NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 3 NC DHHS 52 Communicable Disease During 2010, 20,741 people were tested through the N.C. Rapid HIV Testing Program (40 new cases, 0.2% positivity); 22,171 people were tested through the nontraditional testing site program (68 new cases, 0.3% positivity); 45,861 people were tested through the expanded testing program (96 new cases, 0.3% positive) and 2,230 people were tested through the substance abuse testing program (7 new cases, 0. 3% positive). During 2010, 2,617 people participated in health education and risk reduction programs that were supported by the Communicable Disease Control Branch of the N.C. Division of Public Health. BACKGROUND The information in this chapter will focus on state-supported HIV testing programs and on prevention activities that encourage testing for HIV. In North Carolina, HIV testing is offered at no charge to clients in all local health departments and a number of community-based organizations (CBOs). In addition, the Communicable Disease Branch provides resources and technical support to community health centers, emergency departments, health departments, and state prisons to expand HIV testing in clinical and jail settings. HIV Prevention activities include health education and risk reduction projects conducted by local health departments and CBOs and the Get Real. Get Tested. campaign. History of State-Sponsored HIV Testing in North Carolina The North Carolina State Laboratory of Public Health (SLPH) has been processing blood samples for HIV testing since about 1987. When the state-sponsored program began, testing was available anonymously at 100 local health departments. In September 1991, North Carolina began to evaluate the use of confidential (client’s name obtained), rather than anonymous HIV testing. All 100 sites offered confidential tests, and 18 of these sites continued to offer anonymous testing as an option. Effective in May 1997, anonymous testing in North Carolina was eliminated through a ruling made by the North Carolina Commission of Health Services. The North Carolina Commission for Health Services’ ruling raised some concern that by removing the anonymous test option, testing among people with high risk for HIV infection would be reduced. Prior to implementation of the ruling, the Communicable Disease Branch implemented procedures to increase access to HIV testing by making testing available in nontraditional settings. Some nontraditional test sites are operated by CBOs or local health departments and offer HIV testing in venues outside of traditional health department testing sites. Others are physically located in a local health department but operate outside the normal working hours. Changes in policy, HIV testing technology and funding have enabled the Branch to expand the numbers of people tested for HIV each year. In 2006, the Centers for Disease Control and Prevention (CDC) published revised HIV testing guidelines that encouraged HIV testing for adults as part of their routine healthcare (CDC 2006). Screening for HIV infection should be NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 3 NC DHHS 53 Communicable Disease performed routinely for all patients ages 13 to 64 years, and should be included in the routine panel of prenatal screening tests for all pregnant women. The CDC further recommended that separate written consent for HIV testing should not be required (general consent for medical care should be considered sufficient to encompass consent for HIV testing) and that prevention counseling should not be required with HIV diagnostic testing or as part of screening programs in clinical settings. In response to these new guidelines, North Carolina passed a rule change to the administrative code on November 1, 2007. For tests done in clinical settings, a written HIV consent form and pre-test counseling were no longer required, thereby removing some of the barriers to routine HIV testing (10A N.C.AC 41A.0202(10); 10A N.C.AC 41A.0202(16) ). Additional rule changes require that pregnant women shall be offered HIV tests at the first prenatal visit and in the third trimester (10A N.C.AC 41A.0202(14)). In total, these policy changes have resulted in increased testing in prenatal/obstetric clinics, STD clinics, jails, and prisons in N.C. and greatly facilitated the establishment of new testing programs in emergency departments and community health centers. The N.C. Communicable Disease Branch initiated a rapid testing program in 2004 that has provided new opportunities for improving access to testing in both clinical and outreach settings. Rapid HIV testing technology was first approved by the Food and Drug Administration in 2002. Currently there are 6 FDA approved rapid tests, four of which have Clinical Laboratory Improvement Amendment (CLIA) waivers (Oraquick Advance Rapid HIV1/2 antibody test, Unigold recombigen HIV, Clearview HIV 1/2 Stat Pak, Clearview Complete HIV1/2). Rapid tests with a CLIA waiver can be processed outside of a clinical setting, which allows HIV testing to be done more easily in outreach settings. Rapid HIV tests can be performed using oral fluid, finger stick blood, serum, plasma, or whole blood collected by venipuncture. Preliminary rapid test results can be obtained in 10 to 20 minutes (all preliminary rapid tests should then be followed by a confirmatory conventional HIV test). Because clients undergoing rapid HIV testin

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 5 Communicable Disease CHAPTER 1: SOCIODEMOGRAPHIC CHARACTERISTICS OF THE GENERAL POPULATION IN NORTH CAROLINA HIGHLIGHTS In 2009, North Carolina was the 10th most populous state in the U.S., with an estimated population of 9,535,483. North Carolina’s population increased 18.5 percent from 2000 to 2010. In 2009, North Carolina ranked 3rd in the nation for annual population increase. The N.C. foreign-born population increased 38 percent from 2002 to 2008. North Carolina has the 18th largest non-white population in the nation. North Carolina has the 8th highest percentage of black population in the nation. North Carolina has the 26th largest Hispanic/Latino population and the 10th highest birth rate among Hispanics in the nation. The median age for the Hispanic population was 23.7 years, while the median age for all North Carolinians was 38.3 years in 2008. In 2010, North Carolina was 37th in the nation with a per capita income of $35,638 or 87.8 percent of the national average of $40,584. From 2008 to 2009, 19.7 percent of North Carolinians were living at or below the federal poverty level (FPL); 39.9 percent of the overall population is considered low income (living at or below 199% FPL). From 2008 to 2009, 23 percent of the 19 to 64 year old population in North Carolina was uninsured. About 19 percent of the N.C. population was eligible for Medicaid coverage at some point during 2009. About 70 percent of the state’s population lived in urban areas in 2009. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 6 Communicable Disease SOCIODEMOGRAPHIC CHARACTERISTICS OF NORTH CAROLINA Knowledge of sociodemographic characteristics is paramount to fully understanding the health of a population. Sociodemographics can be used to identify certain populations that may be at greater risk for morbidity and mortality. This knowledge can also assist in identifying underlying factors that may contribute to a health condition. This chapter will discuss the relevant health indicators and sociodemographic characteristics of the population of North Carolina, including age, race/ethnicity, gender, income, poverty, education, and geography. Population According to the 2010 federal census, North Carolina was one of the most rapidly expanding states during the previous decade. From 2000 to 2010, North Carolina’s population grew by 18.5 percent, from 8,049,313 to 9,535,483. Only five other states (Arizona, Idaho, Nevada, Texas, and Utah) grew faster during the last decade. From 2008 to 2009, North Carolina ranked 3rd for single year population growth. According to the N.C. State Demographer, the 2010 North Carolina State provisional population estimate was 9,572,454, with county populations ranging from 4,403 (Tyrrell) to 923,944 (Mecklenburg). More than one-half of North Carolina’s population lived in only 16 counties (Mecklenburg, Wake, Guilford, Forsyth, Cumberland, Durham, Buncombe, Gaston, New Hanover, Union, Onslow, Cabarrus, Johnston, Davidson, Pitt, and Iredell). From July 2008 to July 2009, there were 129,618 births and 79,441 deaths. The average life expectancy for North Carolinians was 75.8 years. The most updated gender and age-specific population information available is for the year 2009, so we use the 2009 population as a substitute for 2010 in order to analyze the HIV disease rates in this profile. In 2009, North Carolina was the 10th most populous state in the United States with an estimated population of 9,380,884 (US Census 2009 population estimate), representing a 16.1 percent increase from that of year 2000. Map 1 displays the population distribution among the counties in North Carolina for 2009 (Appendix A, pg. A-3). Age and Gender Age and gender play an important role in public health planning and in understanding the health of a community. These characteristics are significant indicators of the prevalence of certain diseases, especially for HIV disease and other STDs, as shown in previous Epidemiologic Profiles. Substantial morbidity and social problems among youth are the result of unsafe sex practices, which can result in unwanted pregnancies and STDs, including HIV infection. Nearly one-half of all new sexually transmitted diseases in North Carolina occur in youth ages 15 to 24 years. Research shows that adolescents (ages 13–19 years) are at increased risk, both behaviorally and biologically, for HIV infection. Of the adolescents infected with HIV, more than half are estimated to be unaware of their status due to never having been tested (Rotheram- Borus and Futterman 2000). In 2009, the median age for people living in North Carolina was 36 years old, with 25.7 percent 18 years and younger, and 12.7 percent 65 years and older. Approximately 49 percent of the population is male and 51 percent is female. Table 1.1 displays the North Carolina population in NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 7 Communicable Disease 2009 by selected gender and age groups. The trend in North Carolina follows the typical age trend of slightly more males under 12 years old and more females in the older age groups. North Carolina has a younger population than other states, ranking 10th in the nation in 2009 with more people under 18 years of age. North Carolina’s young population might have extensive health-related needs, such as STDs and unwanted pregnancies. Table 1.1.

Table 1.2 displays the percentages of males and females for the major race/ethnicity categories by North Carolina regions. Race/ethnicity also varies by region with a larger proportion of white non-Hispanics in Western Region, American Indians in Eastern Region, and black non-Hispanics in Eastern Region. A state map showing the N.C regions is displayed on the inside back cover. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 8 Communicable Disease Race/Ethnicity and Gender The racial and ethnic differences of a population play an important role in interpreting gaps in access to health care among the different groups, and these differences are especially true in terms of HIV disease surveillance and intervention. Previous HIV disease surveillance showed that HIV disproportionately affected ethnic minorities in North Carolina. North Carolina has the 18th largest non-white population in the United States (3,058,647 in year 2009) and there are noticeable variations in the demographic composition of North Carolina from region to region. Usually non-white minorities have poorer health conditions and less access to health care. In 2009, 14 counties had populations consisting of more than 50 percent non-white residents (Robeson: 71.0%; Hertford: 65.1%; Bertie: 64.9%; Edgecombe: 61.6%; Warren: 61.4%; Northampton: 59.8%; Halifax: 59.4%; Vance: 56.9 %; Hoke: 55.8%; Washington: 55.0%; Durham: 54.2%; Greene: 53.6%; Anson: 51.3% and Scotland: 50.7%). Maps 3-6 (Appendix A, pp.A-5 to A-8) display the racial and ethnic make-up of North Carolina’s counties, as reported in the 2009 bridged-race estimates (please see Appendix C, pg. C-5 for more information about Census data and the bridged-race categories used to calculate rates). Table 1.3 displays the populations for the major race/ethnicity categories in North Carolina according to the bridged-race estimates for 2009. Table 1.2.

According to the N.C. Health Profile 2009, compared to whites, blacks have higher death rates from heart disease, cancer, HIV, diabetes, homicide, and stroke. North Carolina has seven counties with blacks consisting of more than 50 percent of the total population (Bertie 62.9 %, Hertford 61.3%, Northampton 57.9%, Edgecombe 56.4%, Halifax 53.8%, and Warren County 53.0%). Map 3 (Appendix A, pg. A-5) displays the proportion of black population in 2009 by county. Hispanics Over the years, the N.C. Hispanic population has steadily increased. From 2002 to 2009, the estimated Hispanic/Latino population increased from 451,095 to 717,662, representing a 59.1 percent increase. Hispanics represented 7.7 percent of the population of the state and ranked 26th nationally. North Carolina ranked 10th in Hispanic births in 2008. Compared to other ethnic groups in North Carolina, Hispanics are a relatively young population. Although the median age of the non-Hispanic population is 38.3 years, the median age of Hispanics is 23.7 years. Seventy percent (70%) of Hispanics are under 35 years old, while only 46 percent of non-Hispanic population is in the same age range. Map 5 (Appendix A, pg. A-7) displays the proportion of the Hispanic population in 2009, by county. Within North Carolina, Duplin County had the highest proportion of Hispanic residents (22.0%), followed by Sampson County (17.0%), Lee County (17.0%), and Montgomery County (16.5%). American Indians American Indians represent 1.2 percent of the N.C. population and are one of the largest American Indian populations in the U.S. About 45 percent of American Indians in North Carolina live in Robeson County, followed by Cumberland, Hoke, Mecklenburg, Wake, Jackson, and Scotland counties. Map 4 (Appendix A, pg. A-6) displays the proportion of the American Indian population in 2009 by county. The 2009 N.C. Health Profile shows that American Indians experience higher death rates due to heart disease, stroke, homicide, diabetes, kidney disease, and unintentional motor vehicle injuries compared to the white population. Foreign-born Population According to the Center for Immigration Studies, North Carolina has experienced a dramatic increase in its immigrant population. The immigrant population in North Carolina has increased three and one-half times between 1995 and 2007 (Camarota, 2007). According to the US Census Bureau’s Annual American Community Survey, North Carolina’s foreign-born population increased by 38 percent from 2002 to 2008 (480,248 to 665,270). In 2006, North Carolina ranked 15th nationally for the admitted number of immigrants from other countries. In 2009, 30.6 percent of the foreign-born populations in North Carolina were naturalized citizens, while 69.4 percent were not citizens. The various regions of birth are displayed in Table 1.4. The majority (57.3%) of the foreign-born population come from Latin America, with the other 22.2 percent NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 10 Communicable Disease from Asia, 11.7 percent from Europe, 5.7 percent from Africa, 2.7 percent from North America, and 0.5 percent from Oceania. The majority of the 2009 foreign-born population was male (52.8%) as opposed to female (47.2%). A majority (50%) of the foreign-born population is between ages 25 to 44 years (Table 1.5). About 83 percent speak a language other than English at home and 50 percent do not speak English “very well.” Table 1.3.

These areas are collectively referred to as Core Based Statistical Areas (CBSAs), with a metro area containing a core urban area of 50,000 or more population, and a micro area containing an urban core of at least 10,000 (but less than 50,000) population (U.S. Census Bureau, Population Division). A complete listing of all micropolitan, metropolitan, and combined statistical areas can be obtained at the following website: http://www.census.gov/population/www/estimates/metrodef.html. In the HIV/AIDS Surveillance Supplemental Report, Volume 13 Number 2, the Centers for Disease Control and Prevention (CDC) divides metropolitan areas into large (population greater than or equal to 500,000) and medium-sized metropolitan areas (population 50,000 to 499,999), which are all defined as urban areas. Areas other than metropolitan areas (including micropolitan and non-metropolitan areas) are defined as rural areas. Eleven North Carolina counties, including Anson, Cabarrus, Franklin, Gaston, Guilford, Johnston, Mecklenburg, Randolph, Rockingham, Union and Wake County, are classified as large metropolitan areas, while other metropolitan counties are classified as medium-sized metropolitan areas. About 35 percent of the N.C. population resides in large metropolitan areas, 35 percent in medium-sized metropolitan areas, 22 percent in micropolitan areas, and 8 percent in non-metropolitan areas in 2009. Asian and Pacific Islanders have the highest proportion (56.7%) living in the large metropolitan areas, followed by Hispanics (42.9%). Similar proportions (around 34%) of all race/ethnic groups, except American Indians (18.0%), live in medium-sized metropolitan areas. Data from the U.S. Census showed that in 2006, 65 percent of the general population of the United States was living in large metropolitan areas, 19 percent in medium-size metropolitan areas, and 17 percent in areas other than metropolitan, i.e. rural areas. Compared to national figures, North Carolina has less people in urban areas, substantially less in large metropolitan NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 12 Communicable Disease areas, and more people in rural areas. In North Carolina, a majority of Asians (88%) live in urban areas, followed by Hispanics (76%) and blacks (72%). A majority of American Indians (69%) live in rural areas (Tables 1.6 and 1.7).

HEALTH INDICATORS Poverty and Income Contextual factors such as poverty, income, and education, as well as racial segregation, discrimination, and incarceration rates influence sexual behavior and sexual networks. These factors likely contribute substantially to the persistence of marked racial disparities in rates of STDs (Adimora and Schoenbach 2005). NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 13 Communicable Disease According to the US Department of Commerce’s Bureau of Economic Analysis, the 2010 per capita income for North Carolina is $35,638, or 87.8 percent of the national average of $40,584. This figure represents a 2.5 percent decrease from 2009 and placed North Carolina 37th in the nation for personal per capita income and 4th in the Southeast. Economic recession has impacted North Carolina more than the national average. According to the Bureau of Labor Statistics, the unemployment rate in North Carolina rose from 5.0 percent in January 2008 to 8.5 percent in December 2008 to 11.3 percent in December 2009 but has gone down slightly to 9.8 percent in December 2010. These rates are all higher than the national unemployment rate (the national unemployment rate was 5.0 percent in January 2008 to 7.3 percent in December 2008 to 9.9 percent in December 2009 and to 9.4 percent in December 2010) (Bureau of Labor Statistics). According to Income, Earnings, and Poverty Data from the 2009 American Community Survey, 16.3 percent of North Carolinians are living under the poverty line (while 14.3% nationally). From 2008 to 2009, 19.7 percent of North Carolinians were below the federal poverty level (FPL); with an overall total of 39.9 percent of the population considered low income (199% or below FPL). The median household income in North Carolina was $43,674, a figure much lower than the national median of $50,221. North Carolina ranked 14th in percentage of people in poverty in 2009. Table 1.8 displays the individual poverty rate by age group for the state (2008– 2009) and the nation (2009). Table 1.9 displays the individual poverty rate by race/ethnicity for North Carolina and the United States (2008–2009). Map 7 (Appendix A, pg. A-9) displays the N.C. per capita income for 2009 by county. Health Insurance The percentage of the non-elderly without health insurance in North Carolina has been increasing over the years. In North Carolina (2008–2009), 23 percent of persons ages 19 to 64 years were uninsured (statehealthfacts.org. Kaiser Family Foundation). The primary reason people lack health insurance is financial. According to statehealthfacts.org, 39 percent of the non-elderly (0–64 year olds) uninsured had incomes less than 100 percent of the Federal Poverty Guidelines. Table 1.8.

Kaiser Family Foundation). The racial distribution of non-elderly uninsured people in North Carolina is displayed in Figure 1.1. Figure 1.2 displays the uninsured rates by race/ethnicity for North Carolina as compared to the United States. In 2008 to 2009, 47 percent of Latinos or Hispanics, 22 percent of blacks, 13 percent of whites, and 25 percent of other races were uninsured in North Carolina (statehealthfacts.org. Kaiser Family Foundation). Rates of uninsured among all racial/ethnic groups in North Carolina were higher than those in the nation. Although whites comprise the greatest proportion of the uninsured population (Figure 1.1), minorities have the highest uninsured rates (Figure 1.2). Hispanics in North Carolina are more likely to be uninsured because they are often recent immigrants with low-wage jobs in industries that do not offer health insurance. Table 1.9.

Around five percent of high school students (grades 9–12) dropped out during the 2008 to 2009 school year (N.C. Public Schools Statistical Profile, 2010). Internet access To some extent, health education depends on the facilities at home and in the communities. The internet has become one of the most important venues in health education. In 2007, North Carolina ranked 42nd for the percentage of households with computers (57.7%), and 40th for the percentage of households with internet access (56.8%). Public Aid Total Medicaid and Medicaid-related expenditures in North Carolina for State Fiscal Year (SFY) 2008 were approximately $9 billion for approximately 1.7 million Medicaid recipients (an average $5,262 per recipient). The number of Medicaid recipients increased by 2.6 percent from 2007 to 2008. A total of 1,726,412 North Carolinians, or 18.7 percent of the total N.C. population, received at least one Medicaid service during the 2008 fiscal year (N.C. Medicaid Report 2008). Among them, 40 percent were male and 60 percent were female. Elderly and Disabled recipients comprised about 13.1 and 15.5 percent of total Medicaid recipients, respectively, and their expenditures amounted to $6.2 billion or 65 percent of the total service expenditures. Families and Children comprised 70 percent of all recipients, accounting for $3 billion or about 34 percent of total service expenditures. Aliens and Refugees represented 1.3 percent of all recipients and accounted for about $67.8 million, or about 0.8 percent of total service expenditures. Of all Medicaid services provided, Nursing Facility, Inpatient Hospital, Prescription Drug, and Non-Physician Practitioner services were the top four expensive services and accounted for about $4 billion, or 45 percent of total expenditures. Figure 1.3 displays the percentage of North Carolinians by race who received Medicaid in 2008. Map 8 (Appendix A, pg. A-10) displays the percent of Medicaid eligibles by county for 2010.

The trend in North Carolina follows the typical age trend of slightly more males under 12 years old and more females in the older age groups. North Carolina has a younger population than other states, ranking 10th in the nation in 2009 for people under 18 years of age. Table 1.1.

Table 1.2 displays the percentages of males and females for the major race/ethnicity categories by North Carolina regions. Race/ethnicity also varies by region with a larger proportion of white non-Hispanics in Western Region, American Indians in Eastern Region, and black non-Hispanics in Eastern Region. A state map showing the N.C regions is displayed on the inside back cover. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 8 Communicable Disease Race/Ethnicity and Gender The racial and ethnic differences of a population play an important role in interpreting gaps in access to health care among the different groups, and these differences are especially true in terms of HIV disease surveillance and intervention. Previous HIV disease surveillance showed that HIV disproportionately affected ethnic minorities in North Carolina. North Carolina has the 18th largest non-white population in the United States (3,058,647 in year 2009) and there are noticeable variations in the demographic composition of North Carolina from region to region. Usually, non-white minorities have poorer health conditions and less access to health care. In 2009, 14 counties had populations consisting of more than 50 percent non-white residents (Robeson: 71.0%; Hertford: 65.1%; Bertie: 64.9%; Edgecombe: 61.6%; Warren: 61.4%; Northampton: 59.8%; Halifax: 59.4%; Vance: 56.9 %; Hoke: 55.8%; Washington: 55.0%; Durham: 54.2%; Greene: 53.6%; Anson: 51.3% and Scotland: 50.7%). Maps 3-6 (Appendix A, pp.A-5 to A-8) display the racial and ethnic make-up of North Carolina’s counties, as reported in the 2009 bridged-race estimates (please see Appendix C, pg. C-5 for more information about Census data and the bridged-race categories used to calculate rates).

According to the N.C. Health Profile 2009, compared to whites, blacks have higher death rates from heart disease, cancer, HIV, diabetes, homicide, and stroke. North Carolina has seven counties in which blacks comprise more than 50 percent of the total population (Bertie 62.9 %, Hertford 61.3%, Northampton 57.9%, Edgecombe 56.4%, Halifax 53.8%, and Warren County 53.0%). Map 3 (Appendix A, pg. A-5) displays the proportion of black population in 2009 by county. Hispanics From 2002 to 2009, the estimated Hispanic/Latino population in North Carolina increased by 59.1 percent, from 451,095 to 717,662. Hispanics represented 7.7 percent of the population of the state and ranked 26th nationally. North Carolina ranked 10th in Hispanic births in 2008. Compared to other ethnic groups in North Carolina, Hispanics are a relatively young population. Although the median age of the non-Hispanic population is 38.3 years, the median age of Hispanics is 23.7 years. Seventy percent (70%) of Hispanics are under 35 years old, while only 46 percent of the non-Hispanic population is under 35. Map 5 (Appendix A, pg. A-7) displays the proportion of the Hispanic population in 2009 by county. In North Carolina, Duplin County had the highest proportion of Hispanic residents (22.0%), followed by Sampson County (17.0%), Lee County (17.0%), and Montgomery County (16.5%). American Indians American Indians represent 1.2 percent of the N.C. population and are one of the largest American Indian populations in the United States. About 45 percent of American Indians in North Carolina live in Robeson County, followed by Cumberland, Hoke, Mecklenburg, Wake, Jackson, and Scotland counties. Map 4 (Appendix A, pg. A-6) displays the proportion of Hispanic population in 2009 by county. The 2009 N.C. Health Profile shows that American Indians experience higher death rates due to heart disease, stroke, homicide, diabetes, kidney disease, and unintentional motor vehicle injuries compared to the white population. Foreign-born Population According to the Center for Immigration Studies, North Carolina has experienced a dramatic increase in its immigrant population. The immigrant population in North Carolina has increased three and one-half times between 1995 and 2007 (Camarota, 2007). According to the U.S. Census Bureau’s Annual American Community Survey, North Carolina’s foreign-born population increased by 38 percent from 2002 to 2008 (480,248 to 665,270). In 2006, North Carolina ranked 15th nationally for the admitted number of immigrants from other countries. In 2009, 30.6 percent of the foreign-born populations in North Carolina were naturalized citizens, while 69.4 percent were not citizens. The various regions of birth are displayed in Table 1.4. The majority (57.3%) of the foreign-born population comes from Latin America, with the other 22.2 percent from Asia, 11.7 percent from Europe, 5.7 percent from Africa, 2.7 percent from North America, and 0.5 percent from Oceania. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 10 Communicable Disease The majority of the 2009 foreign-born population was male (52.8%) as opposed to female (47.2%). A majority (50%) of the foreign-born population is between ages 25 to 44 years (Table 1.5). About 83 percent speak a language other than English at home and 50 percent do not speak English “very well.” Table 1.3.

These areas are collectively referred to as Core Based Statistical Areas (CBSAs), with a metro area containing a core urban area of 50,000 or more population, and a micro area containing an urban core of at least 10,000 (but less than 50,000) population (U.S. Census Bureau, Population Division). A complete listing of all micropolitan, metropolitan, and combined statistical areas can be obtained at the following website: http://www.census.gov/population/metro/data/metrodef.html. In the HIV/AIDS Surveillance Supplemental Report, Volume 13 Number 2, the Centers for Disease Control and Prevention (CDC) divides metropolitan areas into large (population greater than or equal to 500,000) and medium-sized metropolitan areas (population 50,000 to 499,999), which are all defined as urban areas. Areas other than metropolitan areas (including micropolitan and non-metropolitan areas) are defined as rural areas. Eleven North Carolina counties, including Anson, Cabarrus, Franklin, Gaston, Guilford, Johnston, Mecklenburg, Randolph, Rockingham, Union and Wake County, are classified as large metropolitan areas, while other metropolitan counties are classified as medium-sized metropolitan areas. About 35 percent of the N.C. population resides in large metropolitan areas, 35 percent in medium-sized metropolitan areas, 22 percent in micropolitan areas, and 8 percent in non-metropolitan areas in 2009. Asian and Pacific Islanders have the highest proportion (56.7%) living in the large metropolitan areas, followed by Hispanics (42.9%). Similar proportions (around 34%) of all race/ethnic groups, except American Indians (18.0%), live in medium-sized metropolitan areas. Data from the U.S. Census showed that in 2006, 65 percent of the general population of the United States was living in large metropolitan areas, 19 percent in medium-size metropolitan areas, and 17 percent in areas other than metropolitan, i.e. rural areas. Compared to national NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 12 Communicable Disease figures, North Carolina has less people in urban areas, substantially less in large metropolitan areas, and more people in rural areas. In North Carolina, a majority of Asians (88%) live in urban areas, followed by Hispanics (76%) and blacks (72%). A majority of American Indians (69%) live in rural areas (Tables 1.6 and 1.7). North Carolina’s metropolitan and non-metropolitan counties are displayed in Map 2 (Appendix A, pg. A-4). Table 1.6.

HEALTH INDICATORS Poverty and Income Contextual factors such as poverty, income, and education, as well as racial segregation, discrimination, and incarceration rates influence sexual behavior and sexual networks. These NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 1 NC DHHS 13 Communicable Disease factors likely contribute substantially to the persistence of marked racial disparities in rates of STDs (Adimora and Schoenbach 2005). According to the U.S. Department of Commerce’s Bureau of Economic Analysis, the 2010 per capita income for North Carolina is $35,638, or 87.8 percent of the national average of $40,584. This figure represents a 2.5 percent decrease from 2009 and placed North Carolina 37th in the nation for personal per capita income and 4th in the Southeast. The economic recession has impacted North Carolina more than the national average. According to the Bureau of Labor Statistics, the unemployment rate in North Carolina rose from 5.0 percent in January 2008 to 8.5 percent in December 2008 to 11.3 percent in December 2009, but went down slightly to 9.8 percent in December 2010. These rates are all higher than the national unemployment rate (the national unemployment rate was 5.0 percent in January 2008 to 7.3 percent in December 2008 to 9.9 percent in December 2009 and to 9.4 percent in December 2010) (Bureau of Labor Statistics). According to Income, Earnings, and Poverty Data from the 2009 American Community Survey, 16.3 percent of North Carolinians were living under the poverty line (while 14.3% nationally). From 2008 to 2009, 19.7 percent of North Carolinians were below the federal poverty level (FPL); with an overall total of 39.9 percent of the population considered low income (199% or below FPL). The median household income in North Carolina was $43,674, a figure much lower than the national median of $50,221. North Carolina ranked 14th in percentage of people in poverty in 2009. Table 1.8 displays the individual poverty rate by age group for the state (2008– 2009) and the nation (2009). Table 1.9 displays the individual poverty rate by race/ethnicity for North Carolina and the United States (2008–2009). Map 7 (Appendix A, pg. A-9) displays the N.C. per capita income for 2009 by county. Health Insurance The percentage of the non-elderly without health insurance in North Carolina has been increasing over the years. In North Carolina (2008–2009), 23 percent of persons ages 19 to 64 years were uninsured (statehealthfacts.org. Kaiser Family Foundation). According to statehealthfacts.org, 39 percent of the non-elderly (0–64 year olds) uninsured had incomes less than 100 percent of the Federal Poverty Guidelines. Table 1.8.

The racial distribution of non-elderly uninsured people in North Carolina is displayed in Figure 1.1. Figure 1.2 displays the uninsured rates by race/ethnicity for North Carolina as compared to the United States. In 2008 to 2009, 47 percent of Latinos or Hispanics, 22 percent of blacks, 13 percent of whites, and 25 percent of other races were uninsured in North Carolina (statehealthfacts.org. Kaiser Family Foundation). Rates of uninsured among all racial/ethnic groups in North Carolina were higher than those in the nation. Although whites comprise the greatest proportion of the uninsured population (Figure 1.1), minorities have the highest uninsured rates (Figure 1.2). Hispanics in North Carolina are more likely to be uninsured because they are often recent immigrants with low-wage jobs in industries that do not offer health insurance. Table 1.9.

Around 5 percent of high school students (grades 9–12) dropped out during the 2008 to 2009 school year (N.C. Public Schools Statistical Profile, 2010). Internet access The internet has become one of the most important venues for health education. In 2007, North Carolina ranked 42nd for the percentage of households with computers (57.7%), and 40th for the percentage of households with internet access (56.8%). Public Aid Total Medicaid and Medicaid-related expenditures in North Carolina for State Fiscal Year (SFY) 2008 were approximately $9 billion for approximately 1.7 million Medicaid recipients (an average $5,262 per recipient). The number of Medicaid recipients increased by 2.6 percent from 2007 to 2008. A total of 1,726,412 North Carolinians, or 18.7 percent of the total N.C. population, received at least one Medicaid service during the 2008 fiscal year (N.C. Medicaid Report 2008). Among them, 40 percent were male and 60 percent were female. Elderly and Disabled recipients comprised about 13.1 and 15.5 percent of total Medicaid recipients, respectively, and their expenditures amounted to $6.2 billion or 65 percent of the total service expenditures. Families and Children comprised 70 percent of all recipients, accounting for $3 billion or about 34 percent of total service expenditures. Aliens and Refugees represented 1.3 percent of all recipients and accounted for about $67.8 million, or about 0.8 percent of total service expenditures. Of all Medicaid services provided, Nursing Facility, Inpatient Hospital, Prescription Drug, and Non-Physician Practitioner services were the top four expensive services and accounted for about $4 billion, or 45 percent of total expenditures.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 17 Communicable Disease CHAPTER 2: SCOPE OF THE HIV DISEASE EPIDEMIC IN NORTH CAROLINA HIGHLIGHTS As of December 31, 2010, the cumulative number of individuals in North Carolina diagnosed with HIV infection was 38,397 people. An estimated 35,000 people were living with HIV/AIDS in North Carolina (including 7,000 individuals who may have been unaware of their infections) as of December 31, 2010. The total number of new HIV diagnoses in 2010 was 1,487 (15.9 per 100,000 population) and the number of new diagnoses of HIV infection among adults/adolescents was 1,482 (19.2 per 100,000 adult/adolescent population). In 2010, the rate of new HIV diagnoses for adult/adolescent blacks (59.7 per 100,000) was more than 10 times greater than that for adult/adolescent whites (5.6 per 100,000). The rate of new HIV diagnosis for adult/adolescent Hispanics (24.7 per 100,000) was more than four times greater than for whites. The highest rate of new HIV diagnoses in 2010 was among adult/adolescent, black males (94.0 per 100,000). This rate was eight times greater than the rate for adult/adolescent white males (11.6 per 100,000). The rate of new HIV diagnoses for adult/adolescent Hispanic males (35.5 per 100,000) was three times the rate among white males. The largest disparity in 2010 was for adult/adolescent black females; with a rate of new HIV diagnoses (30.5 per 100,000) that was nearly 17 times higher than that of white females (1.8 per 100,000). The rate among Hispanic adult/adolescent females (10.0 per 100,000) was more than five times the rate among white females. For 2010 adult/adolescent HIV disease cases, men who have sex with men (MSM) was the risk category in an estimated 57 percent of total cases, heterosexual transmission risk was estimated in 39 percent, and IDU was estimated in 4 percent of total cases (including 1 percent among MSM who also indicated injection drug use). In 2010, MSM (including MSM/IDU) accounted for 76 percent of new HIV disease cases among adult/adolescent males. In 2010, heterosexual contact accounted for about 95 percent and injecting drug use accounted for 5 percent of HIV disease cases for adult/adolescent females. Twenty percent (20%) of newly diagnosed HIV disease cases in 2010 were among adolescent males ages 13 to 24 years old. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 18 Communicable Disease In 2010, 26.0 percent of newly diagnosed HIV disease cases also represented new AIDS cases (i.e., HIV and AIDS diagnosed at the same time or within six months). Mecklenburg County had the most HIV cases diagnosed in 2010 (n=312), followed by Wake County (n=172) and Guilford County (n=118). In 2010, Edgecombe County had the highest three-year average HIV disease rate (41.0 per 100,000), followed by Mecklenburg County (38.1 per 100,000), Durham County (33.7 per 100,000), Northampton County (31.2 per 100,000), Wilson County (29.0 per 100,000), and Guilford County (27.5 per 100,000). In 2010, HIV/AIDS was listed as the 7th leading cause of death for N.C. adults from 25 to 44 years old. The crude HIV disease death rate for blacks is more than 13 times higher than for whites (12.1 vs. 0.9 per 100,000). From the beginning of the epidemic through December 2010 (1983–2010), 19,761 AIDS cases have been reported in North Carolina North Carolina ranked 11th among the 50 states in AIDS cases diagnosed in 2009 (the most recent year available for national comparisons) and 13th in the nation in 2008 for estimated persons living with AIDS. Seven hundred ninety-six AIDS cases were diagnosed in North Carolina in 2010 (8.5 per 100,000 population). Special notes: HIV disease includes all initial diagnoses of HIV as well as those diagnosed with AIDS as their initial diagnosis. More information about this designation of HIV disease can be found in Appendix C (pg. C-3). The HIV disease and AIDS case totals and rates presented in the demographic tables (See Appendix D: Tables A–H, O–P) and discussed in this document are restricted to adults/adolescents only for comparability across states and with national data reported by the Centers for Disease Control and Prevention (CDC). All county totals and references to cumulative cases and persons living with HIV/AIDS do include the 0 to 12 age group. Unless otherwise noted, year refers to year of diagnosis, not year of report, as in previous publications. Unless otherwise noted, references to all racial groups in surveillance data are presented in a race/ethnic designation. Hispanics are considered a separate racial/ethnic group. Thus, “white” refers to white non-Hispanics; “black” refers to black non-Hispanics, etc. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 19 Communicable Disease OVERALL HIV DISEASE TRENDS Figure 2.1 displays the number of HIV disease cases diagnosed from 1992 to 2010 by the year of HIV diagnosis for the individual. New diagnoses for 2010 reflect a continuation of the decline seen in 2009 and the lowest number of new cases diagnosed since the year 2000. The highest point in the HIV epidemic occurred in 1992 in North Carolina with 2,202 cases diagnosed and then moderated from 1995 to 2010 with an average of 1,600 cases (range: 1,400–1,800) each year. The number of HIV disease cases diagnosed in 1992 represented a time when HIV incidence was likely at its peak. From 1995 to 2010, the epidemic was relatively stable; however, changes in reporting practices contributed to the fluctuations during this period, especially for 2002. The increase in cases in 2007 and 2008 was at least partially a result of Communicable Disease Branch efforts to increase HIV testing, including the Get Real. Get Tested campaign, and might not necessarily represent increased incidence. The fact that a decrease was seen in 2009 and further in 2010 might be evidence of a true decline in incidence; however, only additional years of data will determine whether this is actually the case.

Information about persons living with HIV disease is very critical for case follow-up, AIDS care provision, and strategic intervention and testing activities. From the first HIV disease case diagnosed and reported to the Division of Public Health in 1983, through December 31, 2010, the cumulative number of HIV disease cases diagnosed in North Carolina is 38,397, of whom 25,074 are living and 13,323 have died. This number includes some HIV-positive individuals that died of non AIDS-related causes (see pg. 49 for HIV disease related deaths). Figure 2.2 displays the numbers of people living with HIV disease, which represent prevalent cases at the end of each year from 2006 to 2010. The number of people living with HIV disease has been increasing every year, indicating that the number of newly diagnosed HIV disease cases exceeds the number of people who died. Due to the advancement of highly effective anti-retroviral treatment and opportunistic infection control, people with HIV disease may live longer and healthier lives. Persons living with HIV represent individuals that have been diagnosed and subsequently reported to the North Carolina public health surveillance system. Case counts are affected by some amount of under-reporting by clinicians as well as people who are infected with HIV but have not been tested and reported. Efforts to identify the unaware positive population will increase new diagnoses in the future. However, the current number of total living cases in Figure 2.2 under-represents true HIV prevalence and must be adjusted to account for those who have been diagnosed but not reported and those who are unaware of their status. One method for estimating people who are unaware they are HIV positive is based on the CDC estimate that 80 percent of people living with HIV have been tested and know their status. Studies indicate that the N.C. HIV surveillance system currently captures 85 to 95 percent of HIV diagnoses (Appendix B, pg. B-3). Applying these two statistics to our current surveillance total of 25,074 people living in North Carolina with HIV/AIDS increases the estimated HIV disease prevalence in the state to approximately 35,000 people. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 21 Communicable Disease Please note HIV disease reports are periodically updated with vital status data available from the State Center for Health Statistics, thus “living totals” for earlier years, especially for the last two years, have been revised. Demographics of Persons Living with HIV Disease Gender, race/ethnicity, and age distribution Table 2.1 and Table J (Appendix D, pg. D-13) display the demographics of people living with HIV disease as of December 31, 2010. Male prevalent cases were 70 percent of the total and more than double the female prevalence. Blacks comprised the majority (66%) of cases, followed by whites (26%) and Hispanics (6%). Older individuals represented a larger percentage of people living with HIV, as people can live for many years on HAART (Highly Active AntiRetroviral Treatment) with an HIV diagnosis. The greater percentages of males (70%) and blacks (66%) living with HIV disease indicates that these groups are most affected by the HIV epidemic in North Carolina. Table 2.1.

Table I (Appendix D, pg. D-12) shows that 46 percent of living cases were likely infected through MSM activities, 38 percent through heterosexual transmission, 11 percent through injection drug use practices (IDU), and 3 percent through MSM/IDU activities. NEWLY DIAGNOSED HIV DISEASE CASES IN 2010 In 2010, 1,487 (15.9 per 100,000) individuals were newly diagnosed with HIV infection in North Carolina. Of the newly diagnosed persons, 1,482 of them were over 13 years old, which makes the rate of HIV infection among adults/adolescents 19.2 per 100,000 (Table 2.2.). Gender and race/ethnicity Among individuals diagnosed with HIV disease in 2010, about three times as many were male compared to female. Table 2.2 displays the gender and race/ethnicity distribution of newly diagnosed HIV disease among adults/adolescents for 2010. Among the adult/adolescent population newly diagnosed with HIV disease in 2010, blacks made up the majority of cases (65.7%), followed by whites (23.9%), and Hispanics (7.8%). Over the previous five years (2006–2010), blacks have consisted of about 65 percent, whites 26 percent, and Hispanics around 8 percent of total cases, as shown in Figure 2.3 and Table B (Appendix D, pg. D-5). HIV disease rates are different from the proportion of HIV cases because rates take into account the race/ethnicity of the state’s population. The highest rate of newly diagnosed HIV disease was among black males (94.0 per 100,000 adult/adolescent population), which was eight times that for white males (11.6 per 100,000 adult/adolescent population). The HIV disease rate among adult/adolescent black females (30.5 per 100,000 adult/adolescent population) was nearly 17 times higher than the rate for adult/adolescent white females (1.8 per 100,000), which represented the largest disparity noted within gender and race/ethnicity categories.

Adult/adolescent HIV disease rates by race/ethnicity and gender, 2006–2010 Disparities also existed for Hispanics as compared to whites. The rate for adult/adolescent Hispanic men (35.5 per 100,000) was more than three times the rate for white men, and Hispanic males ranked second highest among the gender and race/ethnicity rates. The rate for adult/adolescent Hispanic women (10.0 per 100,000) was more than five times that for white women. Rates for other racial/ethnic groups are based on numbers too small for meaningful comparisons but are displayed in Table 2.2. Figure 2.3 shows that the proportions of racial composition of HIV disease cases remained stable over the last five years, and blacks have consistently represented over 60 percent of HIV disease cases. Figure 2.4 shows the gender and race/ethnicity (for whites, blacks, and Hispanics) specific HIV disease rates. From 2006 to 2010, HIV disease rates for black males have increased slightly while the rates for black females, Hispanic females, and white men have decreased slightly. 0% 10% 20% 30% 40% 50% 60% 70% 2006 2007 2008 2009 2010 Proportion White* Black* Hispanic 0 20 40 60 80 100 120 2005 2006 2007 2008 2009 Rate per 100,000 White* male White* female Black* male Black* female Hispanic male Hispanic female Figure 2.3. Adult/adolescent HIV disease proportions by race/ethnicity, 2006–2010 *non-Hispanic *non-Hispanic NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 24 Communicable Disease Age distribution Most HIV disease diagnoses in 2010 were for adults and adolescents, with less than 1 percent (n=5) of newly diagnosed cases representing infants or children younger than 13 years. Overall, adults ages 20 to 29 years and 40 to 49 years accounted for the greatest proportion (about 54% together) of individuals diagnosed in 2010 (Table 2.3). Figure 2.5 displays the difference of ages between males and females diagnosed with HIV disease in 2010. More males between ages 20 to 29 years (20%) were diagnosed, while proportionately more females between ages 35 to 39 years (16%) and 45 to 49 years (16%) were diagnosed. The difference of ages at diagnosis reflects the difference in risk for male and females. In recent years, HIV disease has been increasing among young black men in North Carolina, unlike previous years, when the HIV epidemic was increasing primarily among an older population. Table 2.3.

Interviewing the patient, the sex and/or drug-using partners, and the treating physician are all methods used to determine risk factors. Ultimately, each case is assigned to one primary risk category based on a hierarchy of disease transmission developed by the CDC and others. Table 2.4 displays the mode of transmission for adult/adolescent HIV disease cases diagnosed in 2010. The principal risk categories were: men who have sex with men (MSM), injection drug use (IDU), and heterosexual sex. The proportion of cases for which there was no identified risk (NIR) reported was substantial (38%). A portion of these NIR cases were classified as NIR not due to missing or incomplete information, but rather because the reported risk(s) did not meet one of the CDC-defined risk classifications; this was especially common for the heterosexual risk category. Meeting the CDC-defined risk of heterosexual transmission includes the requirement of knowing a partner’s risk (sex with known MSM or IDU, or sex with known HIV-positive person). Consequently, some NIR cases have been reevaluated and reassigned to a “presumed heterosexual” risk category based on additional information gathered from follow-up interviews with newly diagnosed individuals (such as the exchange of sex for drugs or money, previous diagnoses with other STDs, or multiple sexual partners). Even with the reassignment of presumed heterosexual risk for some NIR cases, a substantial proportion (24%) of cases remained assigned as no identified risk. 0% 5% 10% 15% 20% 13-14 15-19 20-24 25-29 30-34 35-39 40-44 45-49 50-54 55-59 60-64 65+ Male 0% 5% 10% 15% 20% 13-14 15-19 20-24 25-29 30-34 35-39 40-44 45-49 50-54 55-59 60-64 65+ Female Figure 2.5.

Over the period of 2006 to 2010, MSM have been the leading mode of transmission, increasing from 50 percent in 2006 to 57 percent in 2010 (14% increase). During the same time period, IDU (including MSM/IDU) transmission decreased 43 percent and heterosexual transmission decreased 9 percent. Table 2.5.

Table 2.5 shows that in 2010, MSM were estimated to represent about 57 percent of all HIV disease cases. Heterosexual transmission risk represented about 39 percent of all HIV disease cases and IDU and MSM/IDU (men who have sex with men and inject drugs) represented about 4 percent (including MSM/IDU). More explanation of this general risk reassignment of NIR cases can be found in Appendix C (pg. C-4). In addition, the redistributed risk assignment of NIR cases for all living cases can found in Table I (Appendix D, pg. D-12).

Adult/adolescent males HIV disease cases, 2010 HIV disease cases, 2010 N=354 N=1,128 Gender and mode of transmission HIV risk is very different for males and females; therefore, risk is discussed separately for each gender (Figures 2.7 and 2.8 display adult/adolescent risk categories for each gender). For males, MSM accounted for about 75 percent of HIV disease cases diagnosed in 2010; heterosexual contact cases accounted for about 21 percent of cases; and IDU cases (including MSM/IDU) accounted for about 4 percent. For females, heterosexual contact accounted for about 95 percent of cases and IDU about 5 percent.

D-7 to D-8) display the risk categories by gender for HIV disease cases from 2006 to 2010. For males, the proportion of MSM cases has risen in recent years, from 70 percent in 2006 to 75 percent in 2010. The proportion of IDU cases (including MSM/IDU) for males has declined from 6 percent to 4 percent from 2006 through 2010. For females, the proportion of heterosexual contact reports has increased from 91 to 95 percent and proportion of IDU transmission decreased from 9 to 4 percent from 2006 through 2010. Gender, race/ethnicity, and mode of transmission Among white males, MSM represented 87 percent of cases, heterosexual risk represented 8 percent of cases, and IDU risk represented 2 percent of cases. For black males, MSM represented about 72 percent of HIV cases, heterosexual risk represented about 25 percent of cases, and IDU risk (including MSM/IDU) about 4 percent of cases. The risk breakdown for other races/ethnicities (Hispanics, American Indians, and Asian/Pacific Islanders) are grouped together as “All other” because of low case numbers. Within this aggregated group, MSM risk represented 76 percent of male cases, heterosexual risk 34 percent of cases, and IDU risk (including MSM/IDU) 4 percent of cases. The proportions of HIV cases attributed to heterosexual risk among black males (25%) and other races (34%) are higher than the proportion among white males (8%). Although some of this observed difference may be due to underreporting of MSM activity among minority males, some is attributed to the difference in disease prevalence for each racial/ethnic group and the subsequent affect on risk. Unlike the differences in risk observed for males among the racial/ethnic groups, the majority of all HIV cases among females, regardless of race/ethnicity, are attributed to heterosexual sex. IDU is attributed to a greater proportion of white female cases (17%) than to minority females (2–5%; Figures 2.9 and 2.10).

Because there can be significant delay between infection and subsequent testing and reporting, the age group 13 to 24 years better describes infections that likely occurred during adolescence. In 2010, while just 5.5 percent of total cases diagnosed were found among teenagers from 13 to 19 years, the percentage increased to 22.9 percent when 20 to 24 year olds were included. From 2006 to 2010, the proportion of adolescents among HIV disease cases has increased from 15.9 percent to 22.9 percent of all reports. The proportion of cases among each racial group for adolescents is similar to that of HIV cases overall: minorities are disproportionally affected. Examining the race of new adolescent HIV cases 2010 shows that infections were concentrated among blacks for both men (81%) and women (85%; Figures 2.11 and 2.12). Although adolescent cases do not represent the majority of HIV cases diagnosed in each year, adolescence is the critical age for health education and HIV prevention.

In 2010, all new HIV disease cases among adolescent females were attributed to heterosexual contact. For adolescent males, the proportion of HIV disease cases attributed to heterosexual contact was only 6 percent and the proportion attributed to MSM risk accounted for 92 percent, up from the 88 percent of the diagnosed in 2006. As compared to cases for older persons, adolescent cases are more likely to be associated with sexual activity (99% vs. 96%) and not injection drug use practices. Table C (Appendix D, pg. D-6) shows the detailed statistics about the percentage by gender over the past five years (2006-2010).

For this reason, special emphasis is placed on follow-up for known HIV-infected mothers in North Carolina. Table 2.6 displays the proportion of HIV-infected women who were of child-bearing age (15–44 years old). Approximately 300 women of child-bearing age are diagnosed with HIV each year in North Carolina (65% of total female HIV cases). Note that the number and proportion of HIV diagnoses among N.C. females has decreased in recent years. Readers should keep in mind that the delays in testing and diagnosis can significantly affect the assessment of the actual number of females in this category. Table 2.7 displays the numbers of likely perinatal HIV transmissions that have occurred from 2001 to 2010 by year of birth. These numbers represent pediatric reports that indicate likely perinatal transmission based on exposure categories in HIV surveillance data. Since 2007, there have been decreases noted in the number of HIV-positive babies born in North Carolina. Confirming HIV in perinatal cases takes time, so case totals for recent years should be considered preliminary. In November 2007, North Carolina implemented new HIV testing statues that require every pregnant woman be offered HIV testing by her attending physician at her first prenatal visit and in the third trimester. If there is no HIV result test on record during the current pregnancy, the pregnant woman will be tested at labor and delivery and/or the infant will be tested for HIV. HIV DISEASE AMONG FOREIGN-BORN RESIDENTS Information about foreign-born HIV cases is important for planning outreach and prevention initiatives because messages and information must be tailored or designed for the appropriate culture and language.

The number of HIV disease cases identified among foreign-born people in North Carolina (Figure 2.15) has increased in the last eight years. These increases reflect the greater pattern of migration to the state and may indicate better data collection of country of origin in surveillance data. The number of foreign-born HIV disease cases in 2010 (n=93) represented approximately 9 percent of all foreign-born HIV cases (987) for the last 10 years (2001–2010). Table 2.8 shows the race/ethnicity of the foreign-born HIV cases. Hispanics comprised the highest proportion (61.2%). Non-Hispanic blacks comprised 27.5 percent of cases; whites and Asian/PI made up 5.4 and 4.5 percent respectively. Table 2.8.

The majority (63%) of foreign-born HIV disease cases were diagnosed in urban counties including Wake (20%), Mecklenburg (20%), Durham (9%), Guilford (9%), and Forsyth (5%). About 7 percent of foreign-born cases were diagnosed in rural counties, including Duplin, Davidson, Rowan, Hertford, Craven, Robeson, Sampson, and Lee counties. Figure 2.15.

Large and medium-sized metropolitan areas are usually referred to as urban areas, and micropolitan and non-metropolitan areas as rural areas. According to CDC, 79 percent of national AIDS reports are from large metropolitan areas and 13 percent are from medium-sized metropolitan areas, resulting in 92 percent of reports from urban areas and 8 percent from rural areas in 2009. New HIV Diagnoses in Urban/Rural and Metropolitan Areas While 77 percent of new diagnosis in 2010 were from urban areas, (See Table 2.9, Map 9, Appendix A, pg. A-11), some of the highest HIV disease rates (per 100,000 population) are found in rural areas, especially among blacks and Hispanics (See Table 2.13, Map 10, pg. A-12). The HIV disease rate in medium metropolitan areas in 2010 was slightly higher than the rates in micropolitan and non-metropolitan areas (Table 2.10). Figure 2.16.

Edgecombe County ranked highest with an HIV disease three-year average rate of 41.0 per 100,000 population in 2010, followed by Mecklenburg County (38.1), Durham County (33.7), Northampton County (31.2), Wilson County (29.0), and Guilford County (27.5). Readers are cautioned to view rates carefully, as rates based on small numbers (generally less than 20) are considered unreliable. Persons diagnosed in long-term institutions, such as prisons, are removed from county totals for a better comparison of HIV impact among communities. Table 2.10.

More than 50 percent of living cases diagnosed in North Carolina were from seven counties, which included Mecklenburg (17.6%), Wake (10.4%), Guilford (7.4%), Durham (5.8%), Forsyth (4.9%), Cumberland (4.7%), and New Hanover (2.4%) counties. About 75 percent of living HIV cases were in urban areas and 20 percent in rural areas. Roughly, the prevalence rates for blacks and whites were higher in urban than in rural areas (Table 2.11). County of residence is based on where an individual was living when diagnosed with HIV disease. People may move to other areas in the years after diagnosis. Assuming no significant difference between the numbers of HIV disease cases moving in and out of the original residence county, the statistics still indicate roughly the number and rate of living HIV disease cases in the corresponding counties. Although the highest prevalence rates for whites and blacks were in urban (large and medium-sized metropolitan areas), the highest rate for Hispanics was in non-metropolitan areas (Table 2.12). As with new HIV diagnoses in 2010, more American Indian prevalent cases were diagnosed and reported in micropolitan areas, making the rate in that area much higher than the rate in other areas (Table 2.12). The number of prevalent cases for Asian/Pacific Islanders and American Indians/Alaska Natives were still too small to make comparisons, especially in non-metropolitan areas. Table 2.11.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 36 Communicable Disease Physiographic Regions Geographic areas can be defined in many ways. In this HIV/STD Epidemiologic Profile, data are presented in three categories of geographic areas for the convenience of readers: metropolitan areas, rural/urban areas, and physiographic regions. The distribution of HIV disease is uneven across North Carolina, as can be seen in Maps 9 and 10 (Appendix A, pg. A-11 to A-12). Cases are assigned to the county of residence at first diagnosis. This distribution can be partly explained by the population distribution in Map 1 (Appendix A, pg. A-3), as the epidemic tends to be concentrated in urban areas. The North Carolina state demographer and the GIS lab at the State Center for Health Statistics have produced a Geographic Regional Classification scheme based on "physiographic" qualities. According to this scheme, North Carolina has three regions, West Region, Piedmont Region, and East Region (Table 2.16). Western Region includes counties west of (and including) Surry, Wilkes, Caldwell, Burke, and Rutherford; Eastern Region includes everything east of (and including) Northampton, Halifax, Nash, Johnston, Cumberland, Hoke, Harnett, and Scotland. Piedmont Region includes the counties in between the Western Region and the Eastern Region. Table 2.12.

For American Indian/Alaska Natives, most HIV disease cases were diagnosed in the Eastern Region. For Asian/Pacific Islanders, HIV cases were most prominent in the Piedmont Region, while the rate in the Eastern Region is higher than the Piedmont Region because of a smaller Asian/PI population in Eastern Region (Table 2.13). Among the HIV disease cases living through the end of 2010, a majority of whites, blacks, and Hispanics were diagnosed and reported from Piedmont Region (66%), followed by the Eastern Region. Because the American Indian population in the Piedmont Region is smaller than in the Eastern Region, the prevalence rate in the Piedmont Region is higher than the rate in the Eastern Region (Table 2.14). The Western Region had fewer HIV cases and rates for both new diagnoses and prevalent cases in 2010. Table 2.14.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 38 Communicable Disease HIV DISEASE CASES DIAGNOSED LATE Late testers represent a significant proportion of new HIV diagnoses in North Carolina, indicating the need for increased HIV testing and linkage to medical care. People who test late in the course of HIV infection may already have serious HIV-associated complications and are not able to benefit fully from antiretroviral therapy and prophylaxis to prevent opportunistic infections. Late testing also results in missed opportunities for preventing new HIV infections, as knowledge of positive HIV status promotes adoption of safer sex practices (CDC, 2000). The estimated 20 percent of people in the United States who have HIV and do not know it are estimated to account for 54 percent of new transmissions (Marks, 2006). Table 2.15 shows the proportion of individuals diagnosed as AIDS when they were first diagnosed as HIV infected (late HIV diagnosis or concurrent AIDS cases) in 2010. These persons with concurrent diagnosis are generally referred to as “late testers” and include any person who receives an AIDS diagnosis within six months of the initial HIV positive screening. Hispanic males had the highest proportion (43.9%) of late testers, reflecting possible cultural and language barriers to testing and access to care. Overall, 26.0 percent of newly diagnosed individuals had a concurrent AIDS or late HIV diagnosis in 2010, indicating that they probably had HIV for at least five to seven years (CDC, 2006). Hispanic men experienced a much higher proportion of late testers than other racial/ethnic groups, with nearly 44 percent of new infections diagnosed late. This figure represents an increase from the proportion of late testers among Hispanic men in 2009 (36.5%). As shown in Table 2.16, roughly 25 to 30 percent of individuals newly diagnosed with HIV disease each year also represent AIDS cases (i.e. late testers) during the 2006–2010 period. The significant proportions of late diagnoses indicate the need for increased HIV testing within North Carolina. These figures support the recommendation to include voluntary HIV testing as part of routine medical examinations for all U.S. residents ages 13 to 64 years (CDC, 2006). Table 2.17 displays the gender and race specific proportions of all late testers (concurrent AIDS cases) diagnosed from 2006 to 2010. Blacks comprise 57 to 61 percent of total late testers, whites comprise 23 to 27 percent, and Hispanics comprise 10 to 15 percent in the past five years. Table 2.15.

The N.C. Division of Public Health is actively pursuing new policies and guidelines aimed at making HIV testing part of routine medical care settings and continues to work with HIV-infected persons and their partners to reduce transmission. Rapid HIV tests have also created new opportunities to expand HIV testing into nontraditional and high prevalence settings (e.g. emergency rooms, correctional facilities, community settings and mobile testing sites). In addition, specific initiatives such as the statewide Get Real. Get Tested. Campaign have been designed to encourage North Carolinians to get educated about and tested for HIV. As a result of the implementation of the CDC HIV testing recommendations, statewide Table 2.16.

Get Tested campaign and expanded HIV testing in nontraditional settings, HIV testing has increased substantially. In 2010, the State Laboratory of Public Health performed about 227,038 HIV tests, which represents a 55 percent increase in testing since 2006 when about 146,548 tests were performed (See Chapter 3 for more information about HIV testing in North Carolina). HIV DISEASE STAGING The Centers for Disease Control and Prevention (CDC) uses a new staging system for HIV disease to monitor the epidemic. This staging system is based on CD4+ cell counts as well as the existence of certain HIV-related clinical conditions at the time of diagnosis and is meant to assess the severity of HIV disease. Table 2.18 below shows the current staging definitions used by the CDC. The nine mutually exclusive categories allow clinicians and epidemiologists to view HIV disease on a spectrum, ranging from acute HIV infection (A1) to advanced AIDS (C3). In order to properly stage HIV infection using these new categories, it will be important to increase CD-4 reporting in North Carolina. Table 2.18.

THE IMPACT OF AIDS IN NORTH CAROLINA All 50 states, the District of Columbia, and the U.S. dependent areas report AIDS cases to the Centers for Disease Control and Prevention (CDC) by using a uniform surveillance case definition and a case report form. For persons with laboratory-confirmed HIV infection, AIDS cases represent individuals with CD4+ T-lymphocyte percentages of less than 14 or CD4+ T-lymphocyte counts of fewer than 200 cells/μL or the presence of one of 23 clinical conditions indicating an impaired immune system. The date of AIDS diagnosis represents the date that an individual is diagnosed with AIDS based on the above case definition. Ideally, individuals are diagnosed with HIV infection long before they are diagnosed with AIDS. In North Carolina, however, 49 percent of 2010 AIDS diagnoses were made at the same time or within six months of HIV diagnoses. NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 2 NC DHHS 41 Communicable Disease Monitoring cases that transition from HIV to AIDS in North Carolina provides both a valuable measure of the continuing efficacy of treatment and also indicates which patients may not have access to care. Increases in AIDS diagnoses have several implications. First, these increases may indicate that more HIV-infected individuals are being tested and reported in North Carolina. Another possible implication is that HIV-infected (status aware) individuals are not receiving proper medical care. Finally, increases in AIDS diagnoses may suggest that current treatments are no longer as effective or patients are not adherent to their HIV drug regimes. Because changes in AIDS cases and rates may indicate changes in the anticipated care needs, agencies that provide medical care and support services to persons living with HIV/AIDS should closely monitor cases. NORTH CAROLINA AND THE U.S. All states have name-based AIDS case reporting by law and provide data that are acceptable for state–to–state and state–to–U.S. comparisons. Comparing North Carolina to the nation is limited to earlier years because national surveillance data is released later than state data. According to the Centers for Disease Control and Prevention (CDC), the national AIDS case rate in 2009 was 11.2 per 100,000 population (CDC, HIV/AIDS Surveillance Report, 2009). During the same time period, North Carolina’s AIDS case rate was 11.6 per 100,000 population. North Carolina ranked 9th among all states and the District of Columbia in the number of new AIDS cases reported (Table 2.19). Please note that comparisons made between other states, North Carolina, and the U.S. are based on counts and rates calculated by the CDC and have been statistically adjusted for delays in reporting; these numbers may differ slightly from North Carolina’s unadjusted case counts and rates. The impact of HIV/AIDS in the South is a growing concern. In 2009, the South had 49 percent of new AIDS cases overall, including five of the top 10 states reporting the most AIDS cases (Table 2.19). The South also had the highest regional rate in 2009 (13.9 per 100,000). In 2009, seven of the top 10 states by AIDS case rate were in the South (Top 10: DC, NY, FL, MD, LA, Puerto Rico, DE, NJ, SC, and GA); Mississippi (11th) and North Carolina (12th) followed.

Table 2.20 displays HIV disease prevalence in North Carolina by HIV disease stage (HIV/AIDS), demographic characteristics, and transmission categories. AIDS cases were notably higher (proportionately) than HIV (non AIDS) cases for males, Hispanics, injection drug users (IDU), heterosexuals (CDC defined), and persons ages 45 years and older. Sixty seven percent (67%) of both AIDS and HIV (non AIDS) cases were among blacks in North Carolina. North Carolina ranked 7th in the nation and D.C. for the percentage of all AIDS cases among blacks in 2007 (CDC special request, 2/2010). Table 2.20.

In 2010, 796 new AIDS cases were diagnosed in North Carolina with a rate of 8.5 per 100,000 population (10.3 per 100,000 adult/adolescent population). Most subpopulations in North Carolina have experienced stable or decreasing rates of AIDS. Particularly large decreases were seen among black males ages 35-39 (63% decrease; from 68 cases in 2006 to 25 cases in 2010), black males ages 40 to 44 (45% decrease; from 74 cases in 2006 to 41 cases in 2010) and Hispanic males ages 25 to 29 (67% decrease; from 15 in 2006 to 5 in 2010). However, over the past five years, AIDS cases have increased 60 percent among white males ages 45 to 49 (from 28 cases in 2006 to 45 cases in 2010) and 50 percent among white males ages 50 to 54 (from 16 cases in 2006 to 24 cases in 2010). Although AIDS cases among females have generally decreased over the past five years, increases were observed among younger black females ages 20 to 24 (67% increase; from 6 cases in 2006 to 10 cases in 2010) as well as older black females ages 60 to 64 (200% increase; from 5 cases in 2006 to 15 cases in 2010) and black females age 65 years and older (300% increase; from 2 cases in 2006 to 8 cases in 2010). The number of AIDS cases among American Indians has decreased over the past five years to a minimum of three cases in 2010. Asians experienced a return to pre-2009 levels with three AIDS cases in 2010. AIDS IMPACT ON RACIAL AND ETHNIC MINORITIES As observed for HIV disease, racial and ethnic minorities continue to be disproportionately affected by the AIDS epidemic in North Carolina (Figure 2.17). Blacks account for a disproportionate share of AIDS cases, relative to their size in the population of North Carolina. Figure 2.17.

The disparity between blacks and whites is slightly greater for AIDS than for HIV disease in North Carolina. The AIDS rate among blacks is nearly 10 times higher than for whites while the rate for HIV disease is nine times higher among blacks than whites. In 2010, black males represented 60 percent of all adult/adolescent male AIDS cases and the AIDS rate among adult/adolescent black men (45.7 per 100,000) was 7.5 times the rate for white men in 2010 (6.1 per 100,000). Hispanics represented six percent of all 2010 AIDS cases and the AIDS rate among Hispanic males (18.7 per 100,000 adult/adolescent population) was 3.1 times higher than for whites (Figure 2.18).

Latinas represented three percent of female AIDS cases in 2010 and the AIDS rate among Latinas (3.0 per 100,000) was almost more than three times the rate among white women (Figure 2.19). TREATMENT The lifetime cost of treating HIV disease is approximately $367,000 (CDC, 2010). Identifying HIV infected individuals early in the course of disease and linking those individuals to medical care extends life expectancy, reduces medical costs, and reduces the spread of HIV to others. Current treatment for HIV infection consists of highly active antiretroviral therapy (HAART). Without treatment, progression from HIV infection to AIDS has been observed to occur at a median of between nine to ten years with the median survival time after developing AIDS only 9.2 months (Morgan, 2002). Since the mid 1990s and the introduction of antiretroviral drugs to combat the progression of HIV disease, increases in the length of time between HIV and AIDS diagnosis have been observed in North Carolina surveillance data, generally indicating an improvement in health status and access to care for many HIV infected persons (Figure 2.20). *Average excludes late testers or persons with an AIDS diagnosis within six months of their initial HIV diagnoses Figure 2.20.

HAART does not cure the patient of HIV, nor does it remove all symptoms. If treatment is stopped, high levels of HIV-1 virus return, and may be anti-retroviral drug resistant (Dybul, 2002). Non-adherence to antiretroviral therapy is the major reason individuals fail to benefit from HAART (Becker, 2002). The reasons for non-adherence with HAART are varied and include: poor access to medical care, inadequate social supports, psychiatric disease, and drug abuse (Nieuwkerk, 2001). The complexity of HAART regimens, whether due to pill number, dosing frequency, meal restrictions or side effects of the medication, contribute to the problem of intentional non-adherence (Heath, 2002). Although antiretroviral therapy frequently improves quality of life among symptomatic patients, antiretrovirals may also be associated with reduced quality of life in asymptomatic patients. Adverse effects, including nausea, vomiting, diarrhea, and abdominal pain, as well as the inconvenience of taking medication every day, may outweigh the overall benefit in some patients. As a result, the patient may decide to delay therapy whenever possible. Known complications related to cumulative use of antiretroviral drugs include increased incidence of cardiovascular disease, loss of bone density, loss of subcutaneous fat, the accumulation of fat in some parts of the body, and insulin resistance (DHHS, 2009; Montessori, 2004). SURVIVAL In North Carolina, survival (the estimated proportion of persons surviving a given length of time after diagnosis) increased with the year of diagnosis for HIV diagnoses made during 2001 to 2005, although year-to-year differences were small. Survival decreased as age increased, particularly among the 65+ age group. Survival was greatest for persons ages under 13 and ages 13 to 24 and lowest among the ages 65+ group. Survival was greater among Asians and Hispanics than among blacks, American Indians, and whites (Table 2.21). Survival was greater among MSM and lowest among females who were injecting drug users (IDU). Vital status may not be determined or reported for all cases, however, the reporting of deaths for persons reported as having AIDS is estimated to be more than 90 percent complete.

The North Carolina State Center for Health Statistics reported 321 HIV/AIDS deaths in 2010 (3.4 per 100,000) (Table 2.22). Together with 1,095 deaths occurring from 2007-2009, the total number of deaths caused by HIV disease in North Carolina through 2010 is 11,837 (different from the total number of deaths for persons infected with HIV/AIDS mentioned in pg. 20). Unlike chronic diseases with high death rates among older populations (such as cancer or cardiovascular diseases), HIV/AIDS death rates are concentrated among young and middle-aged people. According to the State Center for Health Statistics, the crude death rate is about 13 times higher for blacks (12.1 per 100,000) than for whites (0.9 per 100,000). Advances in treatment of HIV with antiretrovirals (ARVs) have been reflected with a major increase in life expectancy for people diagnosed with HIV infection. Between 1996 and 2005, average life expectancy after HIV diagnosis increased from 10.5 to 22.5 years (Harrison, 2010). Despite advances in combating HIV, eventually most HIV-infected individuals develop AIDS. However, individuals diagnosed with AIDS have also seen increases in life expectancy: among individuals diagnosed with HIV having an initial CD4 count of <200 or a CD4 count of <200 within 6 months of their initial diagnosis, the average survival time had nearly quadrupled from 1996 to 2005 (5.5 years in 1996 to 19.4 years in 2005; Harrison, 2010). Patients with AIDS mostly die from opportunistic infections or malignancies associated with the progressive failure of the immune system. The age adjusted death rate for HIV disease in North Carolina for 2008 (the last year of data for national comparisons) was 4.2 per 100,000 (the U.S. death rate was 5.3 per 100,000) (CDC, 2011). HIV Disease is a leading cause of death among younger individuals ages 25 to 64 and varies by race/ethnicity in North Carolina (Table 2.23). According to North Carolina’s State Center for Health Statistics (SCHS, 2011), in 2009, HIV disease was the 3rd leading cause of death among black females ages 25 to 44 (n=46 deaths) and the 5th leading cause of death among black males of the same age (n=53 deaths). HIV disease was the 7th leading cause of death among Hispanic males ages 25 to 44 in 2009 (n=10 deaths) and HIV was not listed in the top 10 leading cause of death among Hispanic females of the same age. HIV disease was not listed among the top 10 causes of death among white males or females ages 25 to 44 in 2009. HIV disease was the 8th leading cause of death among American Indian males ages 25 to 44 in 2009 (n=1) and was not a leading cause of death among American Indian females of the same age.

NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 3 NC DHHS 51 Communicable Disease CHAPTER 3: HIV TESTING AND PREVENTION INNORTH CAROLINA HIGHLIGHTS Since November 2002, 176 people have been identified with acute HIV infection by the N.C. State Lab of Public Health (N.C. SLPH). Acute HIV infection refers to the very early, particularly infectious stages of HIV infection. The diagnosis of acute HIV provides an opportunity for early linkage to HIV care and helps reduce potential HIV transmission by newly infected patients. In 2010, 24 acute infections were detected by N.C. SLPH. In 2010, a total of 246,458 persons were tested through state-sponsored HIV testing programs. Of those tested, 1,103 were positive (501 new cases, 546 previous positives, and 56 unknown). In 2010, 49 percent (n=244) of all new HIV cases were found through testing done at STD clinics, where a majority of the testing takes place. New case positivity rates were highest for testing done through partner counseling and referral services (5.7%). HIV positivity rates were also elevated for those tested in HIV test sites (usually nontraditional testing sites, 0.9% positivity), and community health sites (0.5%). In 2010, 69 percent of those tested were female and 30.7 percent were male. Positivity rates were higher for males (0.55%) compared to females (0.06%). Overall, 44 percent of those tested for HIV in 2010 were black non-Hispanic, 27.5 percent were white non-Hispanic, 18.1 percent Hispanic, 1 percent American Indian, 1.1 percent Asian/Pacific Islanders, and 0.1 percent other race/ mixed race . HIV positivity rates were highest for males in the other/mixed race group (1.25%) followed by black non-Hispanic males (0.67%). The disparity was greatest among women. In 2010, the HIV positivity rate for black non-Hispanic women (0.31%) was 2.6 times the rate for white women (0.12%). In 2010, the largest number of new HIV cases was found in the group with the most tests (age 20-29 years, n=250 cases). Overall the highest positivity rates were seen among those 40 years and older (0.29%). The highest new positivity rates in 2010 were among those in the MSM (3.7%) and MSM/IDU (1.0%). The highest new HIV positivity for women was among those with heterosexual high risk (0.13%). NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 3 NC DHHS 52 Communicable Disease During 2010, 20,741 people were tested through the N.C. Rapid HIV Testing Program (40 new cases, 0.2% positivity); 22,171 people were tested through the nontraditional testing site program (68 new cases, 0.3% positivity); 45,861 people were tested through the expanded testing program (96 new cases, 0.3% positive) and 2,230 people were tested through the substance abuse testing program (7 new cases, 0. 3% positive). During 2010, 2,617 people participated in health education and risk reduction programs that were supported by the Communicable Disease Control Branch of the N.C. Division of Public Health. BACKGROUND The information in this chapter will focus on state-supported HIV testing programs and on prevention activities that encourage testing for HIV. In North Carolina, HIV testing is offered at no charge to clients in all local health departments and a number of community-based organizations (CBOs). In addition, the Communicable Disease Branch provides resources and technical support to community health centers, emergency departments, health departments, and state prisons to expand HIV testing in clinical and jail settings. HIV Prevention activities include health education and risk reduction projects conducted by local health departments and CBOs and the Get Real. Get Tested. campaign. History of State-Sponsored HIV Testing in North Carolina The North Carolina State Laboratory of Public Health (SLPH) has been processing blood samples for HIV testing since about 1987. When the state-sponsored program began, testing was available anonymously at 100 local health departments. In September 1991, North Carolina began to evaluate the use of confidential (client’s name obtained), rather than anonymous HIV testing. All 100 sites offered confidential tests, and 18 of these sites continued to offer anonymous testing as an option. Effective in May 1997, anonymous testing in North Carolina was eliminated through a ruling made by the North Carolina Commission of Health Services. The North Carolina Commission for Health Services’ ruling raised some concern that by removing the anonymous test option, testing among people with high risk for HIV infection would be reduced. Prior to implementation of the ruling, the Communicable Disease Branch implemented procedures to increase access to HIV testing by making testing available in nontraditional settings. Some nontraditional test sites are operated by CBOs or local health departments and offer HIV testing in venues outside of traditional health department testing sites. Others are physically located in a local health department but operate outside the normal working hours. Changes in policy, HIV testing technology and funding have enabled the Branch to expand the numbers of people tested for HIV each year. In 2006, the Centers for Disease Control and Prevention (CDC) published revised HIV testing guidelines that encouraged HIV testing for adults as part of their routine healthcare (CDC 2006). Screening for HIV infection should be NC Epidemiologic Profile for HIV/STD Prevention and Care Planning (12/11) Chapter 3 NC DHHS 53 Communicable Disease performed routinely for all patients ages 13 to 64 years, and should be included in the routine panel of prenatal screening tests for all pregnant women. The CDC further recommended that separate written consent for HIV testing should not be required (general consent for medical care should be considered sufficient to encompass consent for HIV testing) and that prevention counseling should not be required with HIV diagnostic testing or as part of screening programs in clinical settings. In response to these new guidelines, North Carolina passed a rule change to the administrative code on November 1, 2007. For tests done in clinical settings, a written HIV consent form and pre-test counseling were no longer required, thereby removing some of the barriers to routine HIV testing (10A N.C.AC 41A.0202(10); 10A N.C.AC 41A.0202(16) ). Additional rule changes require that pregnant women shall be offered HIV tests at the first prenatal visit and in the third trimester (10A N.C.AC 41A.0202(14)). In total, these policy changes have resulted in increased testing in prenatal/obstetric clinics, STD clinics, jails, and prisons in N.C. and greatly facilitated the establishment of new testing programs in emergency departments and community health centers. The N.C. Communicable Disease Branch initiated a rapid testing program in 2004 that has provided new opportunities for improving access to testing in both clinical and outreach settings. Rapid HIV testing technology was first approved by the Food and Drug Administration in 2002. Currently there are 6 FDA approved rapid tests, four of which have Clinical Laboratory Improvement Amendment (CLIA) waivers (Oraquick Advance Rapid HIV1/2 antibody test, Unigold recombigen HIV, Clearview HIV 1/2 Stat Pak, Clearview Complete HIV1/2). Rapid tests with a CLIA waiver can be processed outside of a clinical setting, which allows HIV testing to be done more easily in outreach settings. Rapid HIV tests can be performed using oral fluid, finger stick blood, serum, plasma, or whole blood collected by venipuncture. Preliminary rapid test results can be obtained in 10 to 20 minutes (all preliminary rapid tests should then be followed by a confirmatory conventional HIV test).
