County-Level New HIV Diagnoses, Social Determinants of Health, and Residential Segregation by U.S. Region 2013 to 2023
Health disparities persist along the HIV care continuum. As new HIV diagnoses are a key indicator of the HIV epidemic, we aimed to assess associations of the social determinants of health (SDOH; non-medical factors that are related to health outcomes) and residential segregation, as a proxy for systemic racism, with new HIV diagnosis rates across the major regions of the United States. Publicly available county-level data (i.e., 2013–2023) from a…
Post-transition Care Retention and Viral Suppression Outcomes Among Youth Living with HIV in South Carolina
Youth living with HIV (YLWH) face substantial challenges following transition from pediatric to adult HIV care, yet evidence on post-transition outcomes in the Southern United States remains limited. Using statewide HIV surveillance and administrative data, we conducted a retrospective cohort study of 493 YLWH in South Carolina (SC) who transitioned to adult care between 2005 and 2021. Retention in adult care was defined as ≥ 2 viral load or CD4 …
Geospatial Accessibility Factors Influencing HIV Care Continuum Outcomes in South Carolina
Ending the HIV epidemic in the U.S. requires access to comprehensive care. Traditional measures of service access have focused on distance and time. This study used the enhanced two-step floating catchment area (E2SFCA) method to measure geospatial accessibility and its association with HIV care continuum outcomes. Data from South Carolina’s 2020 enhanced HIV/AIDS reporting system (eHARS) were used to calculate aggregated county-level percentage …
Association between sleep quality and perceived stress among people living with HIV in China
Poor sleep quality and perceived stress are common among people living with HIV (PLWH), but the underlying mechanisms linking the two remain unclear. This study examined whether resilience mediates the relationship between sleep quality and perceived stress, and whether this mediation is moderated by age. We analyzed baseline data from 800 PLWH enrolled in a longitudinal cohort study in Guangxi, China. Validated scales assessed sleep quality, res…
The Association Between Social Determinants of Health and HIV Risk Behaviors and HIV Testing Among Sexual and Gender Minority Individuals
Social determinants of health (SDOH) predispose Sexual and Gender Minority (SGM) individuals to HIV infection through risky behaviors and less HIV testing. This study used data from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) survey to evaluate the association between composite measures of SDOH and HIV risk behaviors and HIV testing among adult SGM population in the US. SGM individuals were identified through two questions that as…
Resilience Mediates the Association Between Discrimination and Psychological Distress Among Rural, Black Women in South Carolina
Introduction The marginalization of intersecting racial, gender, and rural identities compounds the structural vulnerabilities (e.g., discrimination, stigma, health disparities) experienced by Black women in South Carolina's rural areas. Discriminatory experiences can deteriorate mental health; however, resilience can potentially reduce the ill effects of discrimination by decreasing associated psychological distress. This study examines the medi…
