Racial and Ethnic Disparities in HIV Diagnosis Rates by Social Determinants of Health at the Census Tract Level among Adults in the United States and Puerto Rico, 2021.

BACKGROUND: To compare racial and ethnic disparities in HIV diagnosis rates among adults in census tracts with most disadvantaged vs advantaged levels of social determinants of health (SDOH). METHODS: In this ecological analysis, we used the National HIV Surveillance System data in 2021 and SDOH data from 2017-2021 American Community Survey. We measured racial and ethnic disparities stratified by sex in the most disadvantaged quartiles and advantaged quartiles for: 1) Poverty 2) Education level 3) Median household income and 4) Insurance coverage. We calculated 8 relative disparity measures (Black-to-White rate ratio [RR], Hispanic/Latino-to-White RR, Index of Disparity [ID], population-weighted ID, Mean Log Deviation, Theil Index, Population Attributable Proportion, Gini coefficient) and 4 absolute disparity measures (Black-to-White rate difference [RD], Hispanic/Latino-to-White RD, absolute ID, and population-weighted absolute ID). RESULTS: Comparing the most disadvantaged quartiles to the most advantaged quartiles, all four absolute disparity measures decreased, but 7 of the 8 relative disparity measures increased: the median percentage decrease in the absolute measures for males and females respectively was 38.1% and 47.6% for poverty, 12.4% and 42.6% for education level, 43.6% and 44.0% for median household income, and 44.2% and 45.4% for insurance coverage. The median percentage increases for the relative measures for males and females respectively were 44.3% and 61.3% for poverty, 54.9% and 95.3% for education level, 19.6% and 90.0% for median household income, and 32.8% and 46.4% for insurance coverage. CONCLUSION: Racial and ethnic disparities in the most disadvantaged and advantaged quartiles highlight the need for strategies addressing the root causes of disparities.

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.

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.

A Census Tract-Level Examination of HIV Care Outcomes and Social Vulnerability Among Black/African American, Hispanic/Latino, and White Adults in the Southern United States, 2018.

We examined the association between social vulnerability and HIV diagnoses, linkage to HIV medical care, and viral suppression among adults in the Southern U.S. Data from CDC's National HIV Surveillance System (NHSS) were used to determine census tract-level HIV diagnosis rates and percentages of persons linked to care within one month and with viral suppression within six months of diagnosis among Black/African American, Hispanic/Latino, and White adults aged ≥ 18 years residing in the Southern U.S. in 2018. Census tract-level social vulnerability data were obtained from the 2018 CDC Social Vulnerability Index (SVI). Rate and proportion ratios were used to determine the difference between the lowest quartile of SVI scores (Q1) and the highest quartile (Q4) by age group, transmission category, and region of residence and stratified by sex assigned at birth. Areas with the highest social vulnerability (Q4) had the highest rates of HIV diagnoses (Black: 56.5, Hispanic/Latino: 27.2, and White: 10.3). Those in Q4 also had the lowest percentages of adults linked to care (Black: 76.1%, Hispanic/Latino: 81.2%, and White: 77.8%), and the lowest percentages of adults with viral suppression (Black: 59.8%, Hispanic/Latino: 68.4%, and White: 65.7%). This ecological study found an association between social vulnerability, HIV diagnoses, and poorer care outcomes among Black/African American, Hispanic/Latino, and White adults. Tailoring interventions and improving access for persons residing in areas with the highest social vulnerability is necessary to reduce HIV transmission and improve health outcomes in the Southern U.S.

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.

HIV Services and Outcomes During the COVID-19 Pandemic - United States, 2019-2021.

Increasing HIV testing, preexposure prophylaxis (PrEP), and antiretroviral therapy (ART) are pillars of the federal Ending the HIV Epidemic in the U.S. (EHE) initiative, with a goal of decreasing new HIV infections by 90% by 2030.* In response to the COVID-19 pandemic, a national emergency was declared in the United States on March 13, 2020, resulting in the closure of nonessential businesses and most nonemergency health care venues; stay-at-home orders also limited movement within communities (1). As unemployment increased during the pandemic (2), many persons lost employer-sponsored health insurance (3). HIV testing and PrEP prescriptions declined early in the COVID-19 pandemic (4-6); however, the full impact of the pandemic on use of HIV prevention and care services and HIV outcomes is not known. To assess changes in these measures during 2019-2021, quarterly data from two large U.S. commercial laboratories, the IQVIA Real World Data - Longitudinal Prescription Database (IQVIA),† and the National HIV Surveillance System (NHSS)§ were analyzed. During quarter 1 (Q1)¶ 2020, a total of 2,471,614 HIV tests were performed, 190,955 persons were prescribed PrEP, and 8,438 persons received a diagnosis of HIV infection. Decreases were observed during quarter 2 (Q2), with 1,682,578 HIV tests performed (32% decrease), 179,280 persons prescribed PrEP (6% decrease), and 6,228 persons receiving an HIV diagnosis (26% decrease). Partial rebounds were observed during quarter 3 (Q3), with 2,325,554 HIV tests performed, 184,320 persons prescribed PrEP, and 7,905 persons receiving an HIV diagnosis. The proportion of persons linked to HIV care, the number who were prescribed ART, and proportion with a suppressed viral load test (<200 copies of HIV RNA per mL) among those tested were stable during the study period. During public health emergencies, delivery of HIV services outside of traditional clinical settings or that use nonclinical delivery models are needed to facilitate access to HIV testing, ART, and PrEP, as well as to support adherence to ART and PrEP medications.

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.

HIV Care Outcomes in Relation to Racial Redlining and Structural Factors Affecting Medical Care Access Among Black and White Persons with Diagnosed HIV-United States, 2017.

Black/African American (Black) versus White persons are unequally burdened by human immunodeficiency virus (HIV) in the United States. Structural factors can influence social determinants of health, key components in reducing HIV-related health inequality by race. This analysis examined HIV care outcomes among Black and White persons with diagnosed HIV (PWDH) in relation to three structural factors: racial redlining, Medicaid expansion, and Ryan White HIV/AIDS Program (RWHAP) use. Using National HIV Surveillance System, U.S. Census, and Home Mortgage Disclosure Act data, we examined linkage to HIV care and viral suppression (i.e., viral load < 200 copies/mL) in relation to the structural factors among 12,996 Black and White PWDH with HIV diagnosed in 2017/alive at year-end 2018, aged ≥ 18 years, and residing in 38 U.S. jurisdictions with complete laboratory data, geocoding, and census tract-level redlining indexes. Compared to White PWDH, a lower proportion of Black PWDH were linked to HIV care within 1 month after diagnosis and were virally suppressed in 2018. Redlining was not associated with the HIV care outcomes. A higher prevalence of PWDH residing (v. not residing) in states with Medicaid expansion were linked to HIV care ≤ 1 month after diagnosis. A higher prevalence of those residing (v. not residing) in states with > 50% of PWDH in RWHAP had viral suppression. Direct exposure to redlining was not associated with poor HIV care outcomes. Structural factors that reduce the financial burden of HIV care and improve care access like Medicaid expansion and RWHAP might improve HIV care outcomes of PWDH.

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

Linkage to HIV Medical Care and Social Determinants of Health Among Adults With Diagnosed HIV Infection in 41 States and the District of Columbia, 2017.

OBJECTIVES: To reduce the number of new HIV infections and improve HIV health care outcomes, the social conditions in which people live and work should be assessed. The objective of this study was to describe linkage to HIV medical care by selected demographic characteristics and social determinants of health (SDH) among US adults with HIV at the county level. METHODS: We used National HIV Surveillance System data from 42 US jurisdictions and data from the American Community Survey to describe differences in linkage to HIV medical care among adults aged ≥18 with HIV infection diagnosed in 2017. We categorized SDH variables into higher or lower levels of poverty (where <13% or ≥13% of the population lived below the federal poverty level), education (where <13% or ≥13% of the population had

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.

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.

Exploring Changes in Racial/Ethnic Disparities of HIV Diagnosis Rates Under the "Ending the HIV Epidemic: A Plan for America" Initiative.

OBJECTIVES: Racial/ethnic disparities in HIV diagnosis rates remain despite the availability of effective treatment and prevention tools in the United States. In 2019, President Trump announced the "Ending the HIV Epidemic: A Plan for America" (EHE) initiative to reduce new HIV infections in the United States at least 75% by 2025 and at least 90% by 2030. The objective of this study was to show the potential effect of the EHE initiative on racial/ethnic disparities in HIV diagnosis rates at the national level. METHODS: We used 2017 HIV diagnoses data from the Centers for Disease Control and Prevention National HIV Surveillance System. We developed a counterfactual scenario to determine changes in racial/ethnic disparities if the 2017 HIV diagnosis rates were reduced by 75% in the geographic regions targeted by the EHE initiative. We used 4 measures to calculate results: rate ratio, population-attributable proportion (PAP), Gini coefficient, and Index of Disparity. RESULTS: The relative measures of racial/ethnic disparity decreased by 9%-21% in the EHE scenario compared with the 2017 HIV diagnoses data. The largest decrease was in the Hispanic/Latino:white rate ratio (-20.6%) and in the black:white rate ratio (-18.2%). The PAP measure decreased by 11.5%. The absolute versions of the Index of Disparity (unweighted and weighted) were approximately 50% lower in the EHE scenario than in the 2017 HIV diagnoses data. CONCLUSIONS: EHE efforts could reduce but will not eliminate racial/ethnic disparities in HIV diagnosis rates. Efforts to address racial/ethnic disparities should continue, and innovative approaches, specifically those that focus on social and structural factors, should be developed and implemented for populations that are disproportionately affected by HIV in the United States.

Geographic Distribution of HIV Transmission Networks in the United States.

BACKGROUND: Understanding geographic patterns of HIV transmission is critical to designing effective interventions. We characterized geographic proximity by transmission risk and urban-rural characteristics among people with closely related HIV strains suggestive of potential transmission relationships. METHODS: We analyzed US National HIV Surveillance System data of people diagnosed between 2010 and 2016 with a reported HIV-1 partial polymerase nucleotide sequence. We used HIV TRAnsmission Cluster Engine (HIV-TRACE) to identify sequences linked at a genetic distance of ≤0.5%. For each linked person, we assessed median distances between counties of residence at diagnosis by transmission category and urban-rural classification, weighting observations to account for persons with multiple linked sequences. RESULTS: There were 24,743 persons with viral sequence linkages to at least one other person included in this analysis. Overall, half (50.9%) of persons with linked viral sequences resided in different counties, and the median distance from persons with linked viruses was 11 km/7 miles [interquartile range (IQR), 0-145 km/90 miles]. Median distances were highest for men who have sex with men (MSM: 14 km/9 miles; IQR, 0-179 km/111 miles) and MSM who inject drugs, and median distances increased with increasing rurality (large central metro: 0 km/miles; IQR, 0-83 km/52 miles; nonmetro: 103 km/64 miles; IQR, 40 km/25 miles-316 km/196 miles). CONCLUSION: Transmission networks in the United States involving MSM, MSM who inject drugs, or persons living in small metro and nonmetro counties may be more geographically dispersed, highlighting the importance of coordinated health department efforts for comprehensive follow-up and linkage to care.

Exploring Social Determinants of Health as Predictors of Mortality During 2012-2016, Among Black Women with Diagnosed HIV Infection Attributed to Heterosexual Contact, United States.

BACKGROUND: In 2016, black women with HIV infection attributed to heterosexual contact accounted for 47% of all women living with diagnosed HIV, and 41% of deaths that occurred among women with diagnosed HIV in the USA that year. Social determinants of health have been found to be associated with mortality risk among people with HIV. We analyzed the role social determinants of health may have on risk of mortality among black women with HIV attributed to heterosexual contact. METHODS: Data from the Center for Disease Control and Prevention's National HIV Surveillance System were merged at the county level with three social determinants of health (SDH) variables from the U.S. Census Bureau's American Community Survey for black women aged ≥ 18 years with HIV infection attributed to heterosexual contact that had been diagnosed by 2011. SDH variables were categorized into four empirically derived quartiles, with the highest quartile in each category serving as the reference variable. For black women whose deaths occurred during 2012-2016, mortality rate ratios (MRR) were calculated using age-stratified multivariate logistic regressions to evaluate associations between SDH variables and all-cause mortality risk. RESULTS: Risk of mortality was lower for black women aged 18-34 years and 35-54 years who lived in counties with the lowest quartile of poverty (adjusted mortality rate ratio aMRR = 0.56, 95% confidence interval CI [0.39-0.83], and aMRR = 0.67, 95% CI [0.58-0.78], respectively) compared to those who lived in counties with the highest quartile of poverty (reference group). Compared to black women who lived in counties with the highest quartile of health insurance coverage (reference group), the mortality risk was lower for black women aged 18-34 years and black women aged 35-54 who lived in counties with the lowest 2 quartiles of health insurance coverage. Unemployment status was not associated with mortality risk. CONCLUSIONS: This ecological analysis found poverty and lack of health insurance to be predictors of mortality, suggesting a need for increased prevention, care, and policy efforts targeting black women with HIV who live in environments characterized by increased poverty and lack of health insurance.

Trends in Geographic Rates of HIV Diagnoses Among Black Females in the United States, 2010-2015.

BACKGROUND: HIV diagnoses among females in the United States declined 22% from 2010 to 2015, including a 27% decline in diagnoses among black females. Despite this progress, disparities persist. Black females accounted for 60% of new HIV diagnoses among females in 2015. Geographic disparities also exist. This article describes geographic differences in HIV diagnoses among black females in the United States, from 2010 to 2015. MATERIALS AND METHODS: We examined HIV surveillance data from 2010 to 2015 to determine in which geographic areas decreases or increases in HIV diagnoses occurred. We used data from the National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention's (NCHHSTP) AtlasPlus to calculate percent changes in HIV diagnosis rates by geographic region for black females ≥13 years of age. RESULTS: The number of new HIV diagnoses declined 27% among black females from 2010 to 2015. The highest rates of HIV diagnosis per 100,000 population of black females, from 2010 to 2015, were in the Northeast and the South. In 2015, five of the eight states reporting the highest rates of HIV diagnosis (i.e., the highest quartile) were in the South. CONCLUSIONS: HIV diagnosis rates decreased nationally among black females, but the decreases were not uniform within regions or across the United States. Some states experienced increases, and black females in the South and Northeast remain disproportionately affected. Additional research is needed to ascertain factors associated with the increases to continue progress toward reducing HIV-related disparities among females in the United States.

HIV Infection-Related Care Outcomes among U.S.-Born and Non-U.S.-Born Blacks with Diagnosed HIV in 40 U.S. Areas: The National HIV Surveillance System, 2016.

HIV care outcomes must be improved to reduce new human immunodeficiency virus (HIV) infections and health disparities. HIV infection-related care outcome measures were examined for U.S.-born and non-U.S.-born black persons aged ≥13 years by using National HIV Surveillance System data from 40 U.S. areas. These measures include late-stage HIV diagnosis, timing of linkage to medical care after HIV diagnosis, retention in care, and viral suppression. Ninety-five percent of non-U.S.-born blacks had been born in Africa or the Caribbean. Compared with U.S.-born blacks, higher percentages of non-U.S.-born blacks with HIV infection diagnosed during 2016 received a late-stage diagnoses (28.3% versus 19.1%) and were linked to care in ≤1 month after HIV infection diagnosis (76.8% versus 71.3%). Among persons with HIV diagnosed in 2014 and who were alive at year-end 2015, a higher percentage of non-U.S.-born blacks were retained in care (67.8% versus 61.1%) and achieved viral suppression (68.7% versus 57.8%). Care outcomes varied between African- and Caribbean-born blacks. Non-U.S.-born blacks achieved higher care outcomes than U.S.-born blacks, despite delayed entry to care. Possible explanations include a late-stage presentation that requires immediate linkage and optimal treatment and care provided through government-funded programs.

Exploring Factors Associated with Declining HIV Diagnoses Among African American Females.

HIV diagnoses among females in the USA declined 40% during 2005-2014 with the largest decline (42%) among Black/African Americans. African American females remain disproportionately affected. We explored contributions of STD rates and sexual risk behaviors among African American females, HIV diagnoses among potential male partners, and sexual risk behaviors and viral suppression rates among HIV-positive potential male partners to declining rates of HIV diagnoses among African American females. Results suggest temporal trends in the factors that increase HIV infectiousness and transmissibility within sexual networks, i.e., decreases in rates of other sexually transmitted infections among African American females, decreases in HIV diagnoses among potential male partners, and increases in viral suppression among heterosexual and bisexual HIV-positive potential male partners in care, may explain the decline. Findings highlight a need for future research that provides context to the sexual risk behaviors and sexual network factors in order to continue progress.
