The associations of income and Black-White racial segregation with HIV outcomes among adults aged ≥18 years-United States and Puerto Rico, 2019.

OBJECTIVE(S): To examine associations between Index of Concentration at the Extremes (ICE) measures for economic and racial segregation and HIV outcomes in the United States (U.S.) and Puerto Rico. METHODS: County-level HIV testing data from CDC's National HIV Prevention Program Monitoring and Evaluation and census tract-level HIV diagnoses, linkage to HIV medical care, and viral suppression data from the National HIV Surveillance System were used. Three ICE measures of spatial polarization were obtained from the U.S. Census Bureau's American Community Survey: ICEincome (income segregation), ICErace (Black-White racial segregation), and ICEincome+race (Black-White racialized economic segregation). Rate ratios (RRs) for HIV diagnoses and prevalence ratios (PRs) for HIV testing, linkage to care within 1 month of diagnosis, and viral suppression within 6 months of diagnosis were estimated with 95% confidence intervals (CIs) to examine changes across ICE quintiles using the most privileged communities (Quintile 5, Q5) as the reference group. RESULTS: PRs and RRs showed a higher likelihood of testing and adverse HIV outcomes among persons residing in Q1 (least privileged) communities compared with Q5 (most privileged) across ICE measures. For HIV testing percentages and diagnosis rates, across quintiles, PRs and RRs were consistently greatest for ICErace. For linkage to care and viral suppression, PRs were consistently lower for ICEincome+race. CONCLUSIONS: We found that poor HIV outcomes and disparities were associated with income, racial, and economic segregation as measured by ICE. These ICE measures contribute to poor HIV outcomes and disparities by unfairly concentrating certain groups (i.e., Black persons) in highly segregated and deprived communities that experience a lack of access to quality, affordable health care. Expanded efforts are needed to address the social/economic barriers that impede access to HIV care among Black persons. Increased partnerships between government agencies and the private sector are needed to change policies that promote and sustain racial and income segregation.

Trends in HIV care outcomes among adults and adolescents in the U.S. South, 2015-2019.

PURPOSE: HIV disparities continue to persist in the southern United States and among some populations. Early HIV diagnosis, prompt linkage to care, and viral suppression among persons with HIV in the South, in particular the Deep South, are critical to reduce disparities and achieve national prevention goals. METHODS: Estimated annual percent changes were calculated to assess trends during 2015-2019 in percentage distributions for stage of disease at the time of diagnosis, linkage to HIV medical care, and viral suppression. RESULTS: Among 95,488 persons with HIV diagnosed in the South (Deep South: 81,848; Other South:13,640), the overall percentage that received a diagnosis classified as stage 0 increased 9.0%, stages 1-2 increased 1.8%, linkage to HIV care increased 2.9%, and viral suppression increased 5.9%. Changes in care outcomes among American Indian/Alaska Native persons and persons with infection attributed to injection drug use were minimal. CONCLUSIONS: To reach the goals of Ending the HIV Epidemic (EHE) and other federal initiatives, efforts need to focus on prevention and care among persons residing in the South. Addressing factors such as stigma and discrimination and elimination of barriers to HIV testing, care, and treatment are needed to effectively address these disparities in HIV-related care outcomes.

Association Between Social Vulnerability and Rates of HIV Diagnoses Among Black Adults, by Selected Characteristics and Region of Residence - United States, 2018.

During 2018, Black or African American (Black) persons accounted for 43% of all new diagnoses of HIV infection in the United States (1). The annual diagnosis rate (39.2 per 100,000 persons) among Black persons was four times the rate among all other racial/ethnic groups combined, indicating a profound disparity in HIV diagnoses (1,2). Community-level social and structural factors, such as social vulnerability, might help explain the higher rate of HIV diagnoses among Black persons. Social vulnerability refers to the potential negative health effects on communities caused by external stresses (3). CDC used National HIV Surveillance System (NHSS)* and Social Vulnerability Index (SVI)† data to examine the association between diagnosed HIV infections and social vulnerability among Black adults aged ≥18 years. Black adults in communities in the highest quartile of SVI were 1.5 times (rate ratio [RR] = 1.5; 95% CI = 1.4-1.6) as likely to receive a diagnosis of HIV infection as were those in communities in the lowest quartile. Because of a history of racial discrimination and residential segregation, some Black persons in the United States reside in communities with the highest social vulnerability (4,5), and this finding is associated with experiencing increased risk for HIV infection. The development and prioritization of interventions that address social determinants of health (i.e., the conditions in which persons are born, grow, live, work, and age), are critical to address the higher risk for HIV infection among Black adults living in communities with high levels of social vulnerability. Such interventions might help prevent HIV transmission and reduce disparities among Black adults.

Geographic Differences and Social Determinants of Health Among People With HIV Attributed to Injection Drug Use, United States, 2017.

OBJECTIVE: People who inject drugs are among the groups most vulnerable to HIV infection. The objective of this study was to describe differences in the geographic distribution of HIV diagnoses and social determinants of health (SDH) among people who inject drugs (PWID) who received an HIV diagnosis in 2017. METHODS: We used data from the National HIV Surveillance System (NHSS) to determine the counts and percentages of PWID aged ≥18 with HIV diagnosed in 2017. We combined these data with data from the US Census Bureau's American Community Survey at the census tract level to examine regional, racial/ethnic, and population-area-of-residence differences in poverty status, education level, income level, employment status, and health insurance coverage. RESULTS: We observed patterns of disparity in HIV diagnosis counts and SDH among the 2666 PWID with a residential address linked to a census tract, such that counts of HIV diagnosis increased as SDH outcomes became worse. The greatest proportion of PWID lived in census tracts where ≥19% of the residents lived below the federal poverty level, ≥18% of the residents had

A Census Tract-Level Examination of Differences in Social Determinants of Health Among People With HIV, by Race/Ethnicity and Geography, United States and Puerto Rico, 2017.

OBJECTIVE: Social and structural factors, referred to as social determinants of health (SDH), create pathways or barriers to equitable sexual health, and information on these factors can provide critical insight into rates of diseases such as HIV. Our objectives were to describe and identify differences, by race/ethnicity and geography, in SDH among adults with HIV. METHODS: We conducted an ecological study to explore SDH among people with HIV diagnosed in 2017, by race/ethnicity and geography, at the census-tract level in the United States and Puerto Rico. We defined the least favorable SDH as the following: low income (<$40 000 in median annual household income), low levels of education (≥18% of residents have

Geographic Differences in Social Determinants of Health Among US-Born and Non-US-Born Hispanic/Latino Adults With Diagnosed HIV Infection, United States and Puerto Rico, 2017.

OBJECTIVE: HIV disproportionately affects Hispanic/Latino people in the United States, and factors other than individual attributes may be contributing to these differences. We examined differences in the distribution of HIV diagnosis and social determinants of health (SDH) among US-born and non-US-born Hispanic/Latino adults in the United States and Puerto Rico. METHODS: We used data reported to the Centers for Disease Control and Prevention's National HIV Surveillance System (NHSS) to determine US census tract-level HIV diagnosis rates and percentages among US-born and non-US-born Hispanic/Latino adults aged ≥18 for 2017. We merged data from the US Census Bureau's American Community Survey with NHSS data to examine regional differences in federal poverty level, education, median household income, employment, and health insurance coverage among 8648 US-born (n = 3328) and non-US-born (n = 5320) Hispanic/Latino adults. RESULTS: A comparison of US-born and non-US-born men by region showed similar distributions of HIV diagnoses. The largest percentages occurred in census tracts where ≥19% of residents lived below the federal poverty level, ≥18% did not finish high school, the median household income was <$40 000 per year, ≥6% were unemployed, and ≥16% did not have health insurance. A comparison of US-born and non-US-born women by region showed similar distributions. CONCLUSION: The findings of higher numbers of HIV diagnoses among non-US-born Hispanic/Latino adults than among US-born Hispanic/Latino adults, regional similarities in patterns of SDH and HIV percentages and rates, and Hispanic/Latino adults faring poorly in each SDH category are important for understanding SDH barriers that may be affecting Hispanic/Latino adults with HIV in the United States.
