A Census Tract-Level Examination of Diagnosed HIV Infection and Social Vulnerability Themes Among Black/African American, Hispanic/Latino, and White Adults, 2019-USA.

BACKGROUND: Assessing HIV diagnosis and the social vulnerability index (SVI) by themes (socioeconomic status, household composition and disability, minority status and English proficiency, and housing type and transportation) might help to identify specific social factors contributing to disparities across census tracts with high rates of diagnosed HIV infection in the USA. METHODS: We examined HIV rate ratios in 2019 using data from CDC's National HIV Surveillance System (NHSS) for Black/African American, Hispanic/Latino, and White persons aged ≥ 18 years. NHSS data were linked to CDC/ATSDR SVI data to compare census tracts with the lowest SVI (Q1) and highest SVI (Q4) scores. Rates and rate ratios were calculated for 4 SVI themes by sex assigned at birth for age group, transmission category, and region of residence. RESULTS: In the socioeconomic theme analysis, we observed wide within-group disparity among White females with diagnosed HIV infection. In the household composition and disability theme, we observed high HIV diagnosis rates among Hispanic/Latino and White males who lived in the least socially vulnerable census tracts. In the minority status and English proficiency theme, we observed a high percentage of Hispanic/Latino adults with diagnosed HIV infection in the most socially vulnerable census tracts. In the housing type and transportation theme, we observed a high percentage of HIV diagnoses attributed to injection drug use in the most socially vulnerable census tracts. CONCLUSION: The development and prioritization of interventions that address specific social factors contributing to disparities in HIV across census tracts with high diagnosis rates are critical to reducing new HIV infections in the USA.

A Census Tract-Level Examination of Diagnosed HIV Infection and Social Vulnerability among Black/African American, Hispanic/Latino, and White Adults, 2018: United States.

BACKGROUND: To reduce health disparities and improve the health of Americans overall, addressing community-level social and structural factors, such as social vulnerability, may help explain the higher rates of HIV diagnoses among and between race/ethnicity groups. METHODS: Data were obtained from CDC's National HIV Surveillance System (NHSS) and the CDC/ATSDR social vulnerability index (SVI). NHSS data for Black, Hispanic/Latino, and White adults with HIV diagnosed in 2018 were linked to SVI data. To measure the relative disparity, rate ratios (RRs) with 95% CIs were calculated to examine the relative difference comparing census tracts with the lowest SVI scores (quartile 1, Q1) to those with the highest SVI scores (quartile 4, Q4) by sex assigned at birth for age group and region of residence. Differences in the numbers of diagnoses across the quartiles were analyzed by sex assigned at birth and transmission category. RESULTS: There were 13,807 Black, 8747 Hispanic/Latino, and 8325 White adults who received a diagnosis of HIV infection in the United States in 2018-with the highest HIV diagnosis rates among adults who lived in census tracts with the highest vulnerability (Q4). For each race/ethnicity and both sexes, the rate of HIV diagnoses increased as social vulnerability increased. The highest disparities in HIV diagnosis rates by SVI were among persons who inject drugs, and the highest within-group RRs were typically observed among older persons and persons residing in the Northeast. CONCLUSION: To reach the goals of several national HIV initiatives, efforts are needed to address the social vulnerability factors that contribute to racial and ethnic disparities in acquiring HIV and receiving care and treatment.

Geographic Differences in Reaching Selected National HIV Strategic Targets Among People With Diagnosed HIV: 16 US States and Puerto Rico, 2017-2020.

Objectives. To assess geographic differences in reaching national targets for viral suppression, homelessness, and HIV-related stigma among people with HIV and key factors associated with these targets. Methods. We used data from the Medical Monitoring Project (2017-2020) and the National HIV Surveillance System (2019) to report estimates nationally and for 17 US jurisdictions. Results. Viral suppression (range = 55.3%-74.7%) and estimates for homelessness (range = 3.6%-11.9%) and HIV-related stigma (range for median score = 27.5-34.4) varied widely by jurisdiction. No jurisdiction met any of the national 2025 targets, except for Puerto Rico, which exceeded the target for homelessness (3.6% vs 4.6%). Viral suppression and antiretroviral therapy dose adherence were lowest, and certain social determinants of health (i.e., housing instability, HIV-related stigma, and HIV health care discrimination) were highest in Midwestern states. Conclusions. Jurisdictions have room for improvement in reaching the national 2025 targets for ending the HIV epidemic and in addressing other measures associated with adverse HIV outcomes-especially in the Midwest. Working with local partners will help jurisdictions determine a tailored approach for addressing barriers to meeting national targets.

Changes in Diagnoses of Heterosexually Acquired HIV Infection Among Black/African American Males and Females in Seven Southern United States, 2014-2018.

Racial and geographical disparities exist in HIV infections in the USA. The highest burden of HIV diagnoses remains among Black/African American persons and is concentrated in the Southern region. This paper describes within-race changes in HIV diagnoses among heterosexually active Black/African American persons in seven states with the highest rates/100,000 population of HIV diagnoses in the South, during 2014-2018. The total number of diagnoses among Black males and females with infection attributed to heterosexual contact decreased in 2018 compared to 2014. Diagnoses decreased among Black males and females in Louisiana and among Black females in Texas. While the declines indicate progress, Black males and females in the South remain disproportionately affected by HIV. Results support a need for the development, implementation, and evaluation of evidence-based HIV prevention interventions and strategies for heterosexually active persons in jurisdictions that have not seen decreases in HIV diagnoses.

Vital Signs: HIV Infection, Diagnosis, Treatment, and Prevention Among Gay, Bisexual, and Other Men Who Have Sex with Men - United States, 2010-2019.

BACKGROUND: Men who have sex with men (MSM) accounted for two thirds of new HIV infections in the United States in 2019 despite representing approximately 2% of the adult population. METHODS: CDC analyzed surveillance data to determine trends in estimated new HIV infections and to assess measures of undiagnosed infection and HIV prevention and treatment services including HIV testing, preexposure prophylaxis (PrEP) use, antiretroviral therapy (ART) adherence, and viral suppression, as well as HIV-related stigma. RESULTS: The estimated number of new HIV infections among MSM was 25,100 in 2010 and 23,100 in 2019. New infections decreased significantly among White MSM but did not decrease among Black or African American (Black) MSM and Hispanic/Latino MSM. New infections increased among MSM aged 25-34 years. During 2019, approximately 83% of Black MSM and 80% of Hispanic/Latino MSM compared with 90% of White MSM with HIV had received an HIV diagnosis. The lowest percentage of diagnosed infection was among MSM aged 13-24 years (55%). Among MSM with a likely PrEP indication, discussions about PrEP with a provider and PrEP use were lower among Black MSM (47% and 27%, respectively) and Hispanic/Latino MSM (45% and 31%) than among White MSM (59% and 42%). Among MSM with an HIV diagnosis, adherence to ART and viral suppression were lower among Black MSM (48% and 62%, respectively) and Hispanic/Latino MSM (59% and 67%) compared with White MSM (64% and 74%). Experiences of HIV-related stigma among those with an HIV diagnosis were higher among Black MSM (median = 33; scale = 0-100) and Hispanic/Latino MSM (32) compared with White MSM (26). MSM aged 18-24 years had the lowest adherence to ART (45%) and the highest median stigma score (39). CONCLUSION: Improving access to and use of HIV services for MSM, especially Black MSM, Hispanic/Latino MSM, and younger MSM, and addressing social determinants of health, such as HIV-related stigma, that contribute to unequal outcomes will be essential to end the HIV epidemic in the United States.

Trends in HIV Care Outcomes Among Adults and Adolescents-33 Jurisdictions, United States, 2014-2018.

BACKGROUND: With significant improvements in the diagnosis and treatment of HIV, the number of people with HIV in the United States steadily increases. Monitoring trends in HIV-related care outcomes is needed to inform programs aimed at reducing new HIV infections in the United States. SETTING: The setting is 33 United States jurisdictions that had mandatory and complete reporting of all levels of CD4 and viral load test results for each year during 2014-2018. METHODS: Estimated annual percentage change and 95% confidence intervals were calculated to assess trends in stage of disease at time of diagnosis, linkage to HIV medical care within 1 month of HIV diagnosis, and viral suppression within 6 months after HIV diagnosis. Differences in percentages were analyzed by sex, age, race/ethnicity, and transmission category for persons with HIV diagnosed from 2014 to 2018. RESULTS: Among 133,477 persons with HIV diagnosed during 2014-2018, the percentage of persons who received a diagnosis classified as stage 0 increased 13.7%, stages 1-2 (early infections) increased 2.9%, stage 3 (AIDS) declined 1.5%, linkage to HIV medical care within 1 month of HIV diagnosis increased 2.3%, and viral suppression within 6 months after HIV diagnosis increased 6.5% per year, on average. Subpopulations and areas that showed the least progress were persons aged 45-54 years, American Indian/Alaska Native persons, Asian persons, Native Hawaiian/other Pacific Islander persons, and rural areas with substantial HIV prevalence, respectively. CONCLUSIONS: New infections will continue to occur unless improvements are made in implementing the Ending the HIV Epidemic: A Plan for America strategies of diagnosing, treating, and preventing HIV infection.

Care Outcomes Among Black or African American Persons with Diagnosed HIV in Rural, Urban, and Metropolitan Statistical Areas - 42 U.S. Jurisdictions, 2018.

During 2018, Black or African American (Black) persons accounted for 43% of all diagnoses of human immunodeficiency virus (HIV) infection in the United States (1). Among Black persons with diagnosed HIV infection in 41 states and the District of Columbia for whom complete laboratory reporting* was available, the percentages of Black persons linked to care within 1 month of diagnosis (77.1%) and with viral suppression within 6 months of diagnosis (62.9%) during 2018 were lower than the Ending the HIV Epidemic initiative objectives of 95% for linkage to care and viral suppression goals (2). Access to HIV-related care and treatment services varies by residence area (3-5). Identifying urban-rural differences in HIV care outcomes is crucial for addressing HIV-related disparities among Black persons with HIV infection. CDC used National HIV Surveillance System† (NHSS) data to describe HIV care outcomes among Black persons with diagnosed HIV infection during 2018 by population area of residence§ (area). During 2018, Black persons in rural areas received a higher percentage of late-stage diagnoses (25.2%) than did those in urban (21.9%) and metropolitan (19.0%) areas. Linkage to care within 1 month of diagnosis was similar across all areas, whereas viral suppression within 6 months of diagnosis was highest in metropolitan areas (63.8%). The Ending the HIV Epidemic initiative supports scalable, coordinated, and innovative efforts to increase HIV diagnosis, treatment, and prevention among populations disproportionately affected by or who are at higher risk for HIV infection (6), especially during syndemics (e.g. with coronavirus disease 2019).
