Neighborhood Environments and Sexual Risk Behaviors for HIV Infection Among U.S. Women: A Systematic Review

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.

Characterizing the neighborhood risk environment in multisite clinic-based cohort studies: A practical geocoding and data linkages protocol for protected health information

BACKGROUND

Maintaining patient privacy when geocoding and linking residential address information with neighborhood-level data can create challenges during research. Challenges may arise when study staff have limited training in geocoding and linking data, or when non-study staff with appropriate expertise have limited availability, are unfamiliar with a study's population or objectives, or are not affordable for the study team. Opportunities for data breaches may also arise when working with non-study staff who are not on-site. We detail a free, user-friendly protocol for constructing indices of the neighborhood risk environment during multisite, clinic-based cohort studies that rely on participants' protected health information. This protocol can be implemented by study staff who do not have prior training in Geographic Information Systems (GIS) and can help minimize the operational costs of integrating geographic data into public health projects.

METHODS

This protocol demonstrates how to: (1) securely geocode patients' residential addresses in a clinic setting and match geocoded addresses to census tracts using Geographic Information System software (Esri, Redlands, CA); (2) ascertain contextual variables of the risk environment from the American Community Survey and ArcGIS Business Analyst (Esri, Redlands, CA); (3) use geoidentifiers to link neighborhood risk data to census tracts containing geocoded addresses; and (4) assign randomly generated identifiers to census tracts and strip census tracts of their geoidentifiers to maintain patient confidentiality.

RESULTS

Completion of this protocol generates three neighborhood risk indices (i.e., Neighborhood Disadvantage Index, Murder Rate Index, and Assault Rate Index) for patients' coded census tract locations.

CONCLUSIONS

This protocol can be used by research personnel without prior GIS experience to easily create objective indices of the neighborhood risk environment while upholding patient confidentiality. Future studies can adapt this protocol to fit their specific patient populations and analytic objectives.

The Effects of Trauma, Violence, and Stress on Sexual Health Outcomes Among Female Clinic Clients in a Small Northeastern U.S. Urban Center

Background: Threats to sexual health can emerge across one's life span and are influenced by individual and interpersonal experiences, as well as certain environmental exposures. Although previous research has recognized the importance of ecological frameworks to understand the complexity of health and behaviors in marginalized communities, there continues to be a dearth of research that truly utilizes this perspective to gain insight into the multifaceted factors that can concurrently influence threats to sexual health among women. Methods: A sample of 279 ethnoracially diverse women were recruited from a U.S. northeastern small urban center health clinic to participate in a parent study on trauma and immunity. A hierarchical block analysis was conducted to investigate associations between women's experiences of trauma, stress and violence (i.e., childhood trauma (CHT), intimate partner violence (IPV), neighborhood stressors), and sexual health outcomes and behaviors (i.e., lifetime sexually transmitted infection [STI] diagnosis, concurrent partnerships, and lifetime sex trading). Results: In the full hierarchical model, IPV and life stress trauma were associated with lifetime sex trading and partner concurrency. Also in the full model, sexual CHT was associated with lifetime STI acquisition and partner concurrency, while emotional CHT was associated with lifetime sex trading. Lastly, as neighborhood disorder increased, so did the number of lifetime sex trading partners. Conclusion: Sexual health assessments in clinical and community settings require a holistic, comprehensive, and meaningful approach to inform person-centered health promotion intervention. Prevention and treatment interventions require a focus on parents and families, and should assist adolescents and young adults to adopt therapies for healing from these experiences of trauma, violence, and stress. Interventions to enhance sexual health promotion must also include the following: advocacy for safe environments, social policy that addresses lifelong impacts of CHT, and fiscal policy that addresses economic vulnerability among women and threatens sexual health. Further recommendations are discussed.

The Intersection of HIV, Social Vulnerability, and Reproductive Health: Analysis of Women Living with HIV in Rio de Janeiro, Brazil from 1996 to 2016

Comprehensive care for sexual and reproductive health (SRH) and social needs for women living with HIV remains limited globally. We aimed to assess trends in baseline sociodemographic, clinical, sexual, and reproductive characteristics among a cohort of HIV-infected women in Rio de Janeiro from 1996 to 2016. Participants were stratified into four time periods based on year of enrollment; we compared cross-sectional data from each period. Of 1361 participants (median age 36), most were black or mixed race (60.1%), unemployed (52.1%), and without secondary education (54%). Adolescent pregnancy was common (51.5%), and 18.3% reported sexual debut at < 15 years old. Nearly half (45.2%) had < 5 lifetime sexual partners, yet prior syphilis and oncogenic human papillomavirus prevalence were 10.9% and 43.1%, respectively. Lifetime prevalence of induced abortion was 30.3%, and 16% used no contraceptive method. Future research should explore interactions between social vulnerability, HIV, and poor SRH outcomes and healthcare models to alleviate these disparities.
