Neighborhood Deprivation and Racial/Ethnic Disparities in Human Immunodeficiency Virus Viral Suppression: A Single-center, Cross-sectional Study in the United States Midwest

Health Outcomes around Pregnancy and Exposure to HIV/Antiretrovirals (HOPE) study protocol: a prospective observational cohort study of reproductive-aged women living with HIV

INTRODUCTION

Over 265 000 women are living with HIV in the USA, but limited research has investigated the physical, mental and behavioural health outcomes among women living with HIV of reproductive age. Health status during the reproductive years before, during and after pregnancy affects pregnancy outcomes and long-term health. Understanding health outcomes among women living with HIV of reproductive age is of substantial public health importance, regardless of whether they experience pregnancy. The Health Outcomes around Pregnancy and Exposure to HIV/Antiretrovirals (HOPE) study is a prospective observational cohort study designed to investigate physical and mental health outcomes of young women living with HIV as they age, including HIV disease course, engagement in care, reproductive health and choices and cardiometabolic health. We describe the HOPE study design, and characteristics of the first 437 participants enrolled as of 1 January 2024.

METHODS AND ANALYSIS

The HOPE study seeks to enrol and follow 1630 women living with HIV of reproductive age, including those with perinatally-acquired HIV, at 12 clinical sites across 9 US states and Puerto Rico. HOPE studies multilevel dynamic determinants influencing physical, mental and social well-being and behaviours of women living with HIV across the reproductive life course (preconception, pregnancy, post partum, not or never-pregnant), informed by the socioecological model. Key research areas include the clinical course of HIV, relationship of HIV and antiretroviral medications to reproductive health, pregnancy outcomes and comorbidities and the influence of racism and social determinants of health. HOPE began enrolling in April 2022.

ETHICS AND DISSEMINATION

The HOPE study received approval from the Harvard Longwood Campus Institutional Review Board, the single institutional review board of record for all HOPE sites. Results will be disseminated through conference presentations, peer-reviewed journals and lay summaries.

Neighborhood characteristics and HIV treatment outcomes: A scoping review

Recognizing challenges faced by people living with HIV is vital for improving their HIV treatment outcomes. While individual-level interventions play a crucial role, community factors can shape the impact of individual interventions on treatment outcomes. Understanding neighborhood characteristics' association with HIV treatment outcomes is crucial for optimizing effectiveness. This review aims to summarize the research scope on the association between neighborhood characteristics and HIV treatment outcomes. The databases PubMed, CINAHL (EBSCOhost), Embase (Elsevier), and PsychINFO (EBSCOhost) were searched from the start of each database to Nov 21, 2022. Screening was performed by three independent reviewers. Full-text publications of all study design meeting inclusion criteria were included in the review. There were no language or geographical limitations. Conference proceedings, abstract only, and opinion reports were excluded from the review. The search yielded 7,822 publications, 35 of which met the criteria for inclusion in the review. Studies assessed the relationship between neighborhood-level disadvantage (n = 24), composition and interaction (n = 17), social-economic status (n = 18), deprivation (n = 16), disorder (n = 8), and rural-urban status (n = 7) and HIV treatment outcomes. The relationship between all neighborhood characteristics and HIV treatment outcomes was not consistent across studies. Only 7 studies found deprivation had a negative association with HIV treatment outcomes; 6 found that areas with specific racial/ethnic densities were associated with poor HIV treatment outcomes, and 5 showed that disorder was associated with poor HIV treatment outcomes. Three studies showed that rural residence was associated with improved HIV treatment outcomes. There were inconsistent findings regarding the association between neighborhood characteristics and HIV treatment outcomes. While the impact of neighborhood characteristics on disease outcomes is highly recognized, there is a paucity of standardized definitions and metrics for community characteristics to support a robust assessment of this hypothesis. Comparative studies that define and assess how specific neighborhood indicators independently or jointly affect HIV treatment outcomes are highly needed.

Association of Neighborhood Economic Status and Race With Developing Pelvic Inflammatory Disease After Sexually Transmitted Infections

OBJECTIVE

To explore the association of neighborhood-level socioeconomic status (SES) and race with developing pelvic inflammatory disease (PID) after sexually transmitted infection (STI) among female adolescents and young adults in Maryland.

METHODS

We used Maryland statewide hospital claims data (outpatient and inpatient visits) for this retrospective cohort study. Female adolescents and young adults aged 15-24 years who had at least one STI from July 1, 2013, to March 31, 2015, were included. A participant entered the cohort on the date of the first STI diagnosis and was followed up until PID occurrence or 3 years after the first STI. Median household income of the participant's residential ZIP code tabulation area was used as the neighborhood-level SES. Discrete-time hazard models were used to estimate the hazard of PID.

RESULTS

Of the 2,873 participants, 88.5% were of Black race, and 67.2% were aged 20-24 years. The hazard of PID after an STI among Black women was 1.40 times that of White women (95% CI 1.06-1.85). After adjustment for age, insurance type, and number of STI events, the hazard ratio (HR) did not change. However, adding neighborhood-level SES to the model attenuated the disparity in PID after STI between Black and White women (HR 1.25, 95% CI 0.94-1.67).

CONCLUSION

Racial disparities in PID diagnosis are mitigated by neighborhood-level SES.

Resilience and Its Limits: The Roles of Individual Resilience, Social Capital, Racial Discrimination, and Binge Drinking on Sexual Behavior Among Black Heterosexual Men

In response to the increased recognition of racism as a public health crisis, we assessed links between racial discrimination and HIV-related risk behavior for Black men. Specifically, using survey data from 530 Black heterosexual men (18-44 years old, M = 31.0, SD = 7.8), we tested two moderated-mediation models: (1) a protective model, in which resilience and social capital protected against the indirect effect of racial discrimination on alcohol-related sexual behavior via binge drinking, and (2) a bounded model, in which racial discrimination limited the indirect effects of resilience and social capital on alcohol-related sexual behavior via binge drinking. We found support for the bounded model only. Specifically, resilience was indirectly associated with decreased alcohol-related sexual behavior via lower binge drinking when racial discrimination was low to moderately high, but not when racial discrimination was at its highest levels. Resilience was not directly associated with alcohol-related sexual behavior. Social capital was directly related to lower odds of alcohol-related sexual behavior. At high levels of racial discrimination, however, social capital was indirectly related to increased alcohol-related sexual behavior via binge drinking. High levels of racial discrimination limit beneficial effects of resilience on alcohol-related sexual behavior. Social capital maintains a beneficial effect if social bonds are not associated with binge-drinking norms or behaviors. Results highlight the limitations of individual-level resilience and the need to conceptualize and support resilience as a social-structural resource.

The relationship between state-level structural racism and disparities between the non-hispanic black and non-hispanic white populations in multiple health outcomes

AIMS

While several studies have examined the impact of individual indicators of structural racism on single health outcomes, few have explicitly modeled racial disparities in a wide range of health outcomes using a multidimensional, composite structural racism index. This paper builds on the previous research by examining the relationship between state-level structural racism and a wider array of health outcomes, focusing on racial disparities in mortality from firearm homicide, infant mortality, stroke, diabetes, hypertension, asthma, HIV, obesity, and kidney disease.

METHODS

We used a previously developed state structural racism index that consists of a composite score derived by averaging eight indicators across five domains: (1) residential segregation; (2) incarceration; (3) employment; (4) economic status/wealth; and (5) education. Indicators were obtained for each of the 50 states using Census data from 2020. We estimated the Black-White disparity in each health outcome in each state by dividing the age-adjusted mortality rate for the non-Hispanic Black population by the age-adjusted mortality rate for the non-Hispanic White population. These rates were obtained from the CDC WONDER Multiple Cause of Death database for the combined years 1999-2020. We conducted linear regression analyses to examine the relationship between the state structural racism index and the Black-White disparity in each health outcome across the states. In multiple regression analyses, we controlled for a wide range of potential confounding variables.

RESULTS

Our calculations revealed striking geographic differences in the magnitude of structural racism, with the highest values generally being observed in the Midwest and Northeast. Higher levels of structural racism were significantly associated with greater racial disparities in mortality for all but two of the health outcomes.

CONCLUSIONS

There is a robust relationship between structural racism and Black-White disparities in multiple health outcomes across states. Programs and policies to reduce racial heath disparities must include strategies to help dismantle structural racism and its consequences.

Moderation effect of community health on the relationship between racial/ethnic residential segregation and HIV viral suppression in South Carolina: A county-level longitudinal study from 2013 to 2018

Background

Viral suppression is the ultimate goal of the HIV treatment cascade and a primary endpoint of antiretroviral therapy. Empirical evidence found racial/ethnic disparities in viral suppression among people living with HIV (PWH), but the evidence of the relationship between racial/ethnic residential segregation and place-based viral suppression is scarce. Further exploring potential structural moderators in this relationship has substantial implications for healthcare policymaking and resource allocation. The current study aimed to investigate the spatial-temporal disparities in the HIV viral suppression rate across 46 counties in South Carolina from 2013 to 2018. We also examined the impact of racial/ethnic residential segregation and the moderation effect of community health, one measurement of community engagement and volunteerism.

Methods

The proportion of PWH who achieved viral suppression for each county and calendar year was calculated using de-identified electronic medical records. The isolation index was calculated and used to measure racial/ethnic residential segregation. The community health index and other county-level factors were directly extracted from multiple publicly available datasets. We used geospatial mapping to explore the spatial-temporal variations of HIV viral suppression rates. Hierarchical quasi-binominal regression models were used to examine the impacts of racial/ethnic residential segregation on county-level viral suppression rate by the extent of community health.

Results

From 2013 to 2018, the average viral suppression rate across 46 counties in SC increased from 64.3% to 65.4%. Regression results revealed that counties with high racial/ethnic residential segregation were more likely to have a low viral suppression rate (β = -0.56, 95% CI: -0.75 to -0.37). In counties with high levels of community health, the impact of racial/ethnic residential segregation on viral suppression rate decreased as compared with those with low levels of community health (β = 5.50, 95% CI: 0.95-10.05).

Conclusions

Racial/ethnic residential segregation acts as a structural barrier to placed-based viral suppression rates and compromises the goal of the HIV treatment cascade. Concentrated and sustained county-level interventions aiming to improve community health can be practical approaches to promote health equity in HIV treatment and care.

Structural vulnerability among patients with HIV and SARS-CoV-2 Co-infection: descriptive case series from the U.S. Midwest

HIV and COVID-19 disproportionately impact marginalized populations, especially racial and ethnic minorities. This descriptive case series from an HIV clinic in the U.S. Midwest explores the sociodemographic and clinical characteristics of 37 individuals with HIV and SARS-CoV-2 co-infection. All 37 had suppressed viral loads prior to diagnosis with COVID-19, and all 37 survived. Relative to our overall HIV clinic population, over twice as many Hispanic patients, three times as many undocumented patients, and four times as many refugee patients contracted COVID-19, highlighting the structural vulnerability of these sub-populations.

Social Disparities among Sudden Death victims with HIV

Although cardiovascular death is a growing source of mortality for people living with human immunodeficiency virus (HIV), the risk factors and circumstances surrounding sudden death in this population are poorly understood. We compared 399 adult sudden death victims reported by Emergency Medical Services in North Carolina to 1,114 controls. Sudden death was more common among HIV-positive than HIV-negative individuals (OR: 2.59, 95% CI: 1.15-5.83). In a multivariable model of sudden death victims including Black race, BMI, and history of divorce, incarceration, substance abuse, and respiratory disease, HIV-positive individuals were more likely to be Black (adjusted OR [aOR]: 6.04, 95% CI: 1.08-33.7) or divorced (aOR: 4.71, 95% CI: 1.04-21.3), adjusted for all other variables in the model. Compared to controls with HIV, sudden death victims with HIV were more likely to have a history of incarceration, divorce, respiratory disease, alcohol abuse, or dyslipidemia. A qualitative assessment of victims suggested that many died in isolation, suffering from past and current substance abuse and depression. HIV infection appears to be an important risk factor for sudden death, and incarceration history, social isolation, and medical comorbidities contribute to sudden death risk for HIV-positive individuals.

Association of Race and Other Social Determinants of Health With HIV Pre-Exposure Prophylaxis Use: A County-Level Analysis Using the PrEP-to-Need Ratio

Research is limited on the effect of racism and social determinants of health on HIV pre-exposure prophylaxis (PrEP) use. This study used the PrEP-to-Need Ratio (PNR), which measures PrEP prescriptions divided by HIV diagnoses in the county, to evaluate sufficient PrEP use. AIDSVu datasets were compared to county-level social determinants of health. Standardized regression coefficients (β) were compared to identify strongest associations with PNR. Overall, factors including percent African American and percent uninsured had negative correlations with PNR, whereas median household income and severe housing cost burden had positive associations. Stratifying for population size, percent African American, percent uninsured, and severe housing cost burden were significant for low population areas, whereas median household income, percent in poverty, percent uninsured, and percent African American were significant for large populations. To reduce PrEP disparities, public health must develop strategies to reach those most in need, especially historically disadvantaged communities.

A Systematic Review of Neighborhood-Level Influences on HIV Vulnerability

A better understanding of the social-structural factors that influence HIV vulnerability is crucial to achieve the goal of ending the HIV epidemic by 2030. Given the role of neighborhoods in HIV outcomes, synthesis of findings from such research is key to inform efforts toward HIV eradication. We conducted a systematic review to examine the relationship between neighborhood-level factors (e.g., poverty) and HIV vulnerability (via sexual behaviors and substance use). We searched six electronic databases for studies published from January 1, 2007 through November 30, 2017 (PROSPERO CRD42018084384). We also mapped the studies' geographic distribution to determine whether they aligned with high HIV prevalence areas and/or the "Ending the HIV Epidemic: A Plan for the United States". Fifty-five articles met inclusion criteria. Neighborhood disadvantage, whether measured objectively or subjectively, is one of the most robust correlates of HIV vulnerability. Tests of associations more consistently documented a relationship between neighborhood-level factors and drug use than sexual risk behaviors. There was limited geographic distribution of the studies, with a paucity of research in several counties and states where HIV incidence/prevalence is a concern. Neighborhood influences on HIV vulnerability are the consequence of centuries-old laws, policies and practices that maintain racialized inequities (e.g., racial residential segregation, inequitable urban housing policies). We will not eradicate HIV without multi-level, neighborhood-based approaches to undo these injustices. Our findings inform future research, interventions and policies.

Ending the HIV epidemic for all, not just some: structural racism as a fundamental but overlooked social-structural determinant of the US HIV epidemic

PURPOSE OF REVIEW

We review the recent theoretical and empirical literature on structural racism, social determinants of health frameworks within the context of HIV prevention and treatment, and criticism of the national responses to the US epidemic.

RECENT FINDINGS

In line with growing mainstream attention to the role of structural racism and health inequities, recent editorials and studies cite ending structural racism as an essential step to ending the US HIV epidemic. Recent studies demonstrate that barriers rooted in structural racism such as incarceration, housing instability, police discrimination, neighborhood disadvantage, health service utilization and community violence, and poor or no access to social services, transportation, and childcare, are barriers to HIV prevention. Recent articles also criticize national responses to HIV such as the ending the HIV epidemic (EHE) and National HIV/AIDS Strategy plans for failing to address structural racism and prioritize community engagement in EHE efforts.

SUMMARY

Collectively, the articles in this review highlight a growing consensus that the US has no real chance of EHE for all, absent a meaningful and measurable commitment to addressing structural racism and intersectional discrimination as core determinants of HIV, and without more equitable engagement with community-based organizations and communities disproportionately affected by HIV.

Act Healthy: A Randomized Clinical Trial Evaluating a Behavioral Activation Intervention to Address Substance Use and Medication Adherence Among Low-Income, Black/African American Individuals Living with HIV/AIDS

There is a need for parsimonious behavioral interventions to support HIV and substance use treatment outcomes for low-income, Black/African American individuals living with HIV. This randomized clinical trial (N = 61) evaluated Act Healthy (AH), an integrated behavioral intervention to reduce substance use and improve medication adherence, compared to supportive counseling (SC) plus Life-Steps medication adherence counseling on substance use, craving, adherence-related outcomes, and depression over one year. Participants in AH had significantly steeper decreases in cravings compared to SC, but no significant differences in substance use. Across both groups, there was a significant increase in probability of being on antiretroviral therapy (ART) (86% on ART at 12 months vs. 56% at baseline), and a significant decrease in medication nonadherence. Findings provide preliminary support for an intervention to reduce cravings and strategies to improve ART use in a hard-to-reach, vulnerable population at high risk for poor treatment outcomes and ongoing HIV transmission. TRIAL REGISTRATION: ClinicalTrials.gov trial registration number: identifier: NCT01351454. Retrospectively registered on May 10, 2011.

Racial/Ethnic Inequities in Healthcare-associated Infections Under the Shadow of Structural Racism: Narrative Review and Call to Action

Purpose of Review

The purpose of this study is to review racial and ethnic inequities in the incidence and prevention of healthcare-associated infections (HAIs) in the USA, identify gaps in the literature, and recommend future directions to mitigate these inequities.

Recent Findings

While some existing literature has identified the presence of racial/ethnic inequities in HAI incidence and outcomes, few studies to date have evaluated whether HAI prevention efforts have mitigated these inequities. Factors contributing to inequities in HAI prevention may include unconscious bias of healthcare professionals towards minoritized patients; socioeconomic and structural inequities disparately affecting minoritized communities; the racial segregation of quality healthcare through hospital price discrimination; divergent reimbursement rates between public and private insurers; policies or performance metrics which underfund and financially penalize safety-net hospitals; and insufficient research evaluating and addressing HAI inequities.

Summary

Expansion of the literature is needed to further interrogate root causes and evaluate the impact of interventions on racial/ethnic inequities in HAI incidence. Measures to mitigate inequities might include teaching healthcare workers how to recognize and mitigate unconscious biases, expanding community resources which address the social and structural determinants of health, increasing access to preventive health services, reforming federal and institutional policies to better support safety-net hospitals and disincentivize price discrimination, and improving diversity and inclusion within the health workforce.

Adopting a "Compound" Exposome Approach in Environmental Aging Biomarker Research: A Call to Action for Advancing Racial Health Equity

BACKGROUND

In June 2020, the National Academies of Sciences, Engineering, and Medicine hosted a virtual workshop focused on integrating the science of aging and environmental health research. The concurrent COVID-19 pandemic and national attention on racism exposed shortcomings in the environmental research field's conceptualization and methodological use of race, which have subsequently hindered the ability of research to address racial health disparities. By the workshop's conclusion, the authors deduced that the utility of environmental aging biomarkers-aging biomarkers shown to be specifically influenced by environmental exposures-would be greatly diminished if these biomarkers are developed absent of considerations of broader societal factors-like structural racism-that impinge on racial health equity.

OBJECTIVES

The authors reached a post-workshop consensus recommendation: To advance racial health equity, a "compound" exposome approach should be widely adopted in environmental aging biomarker research. We present this recommendation here.

DISCUSSION

The authors believe that without explicit considerations of racial health equity, people in most need of the benefits afforded by a better understanding of the relationships between exposures and aging will be the least likely to receive them because biomarkers may not encompass cumulative impacts from their unique social and environmental stressors. Employing an exposome approach that allows for more comprehensive exposure-disease pathway characterization across broad domains, including the social exposome and neighborhood factors, is the first step. Exposome-centered study designs must then be supported with efforts aimed at increasing the recruitment and retention of racially diverse study populations and researchers and further "compounded" with strategies directed at improving the use and interpretation of race throughout the publication and dissemination process. This compound exposome approach maximizes the ability of our science to identify environmental aging biomarkers that explicate racial disparities in health and best positions the environmental research community to contribute to the elimination of racial health disparities. https://doi.org/10.1289/EHP8392.
