Scoping review of HIV-related intersectional stigma among sexual and gender minorities in sub-Saharan Africa.

OBJECTIVES: Sexual and gender minority (SGM) populations in sub-Saharan Africa (SSA) are disproportionately impacted by HIV and often face multiple HIV-related stigmas. Addressing these stigmas could reduce SGM HIV vulnerability but little is known about how the stigmas operate and intersect. Intersectional stigma offers a lens for understanding the experiences of stigmatised populations and refers to the synergistic negative health effects of various systems of oppression on individuals with multiple stigmatised identities, behaviours or conditions. This review aims to (1) assess how often and in what ways an intersectional lens is applied in HIV-related stigma research on SGM populations in SSA and (2) understand how intersectional stigma impacts HIV risk in these populations. DESIGN: Scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. DATA SOURCES: Public health and regional databases were searched in 2020 and 2022. ELIGIBILITY CRITERIA: Articles in French and English on HIV-related stigma and HIV outcomes among men who have sex with men, women who have sex with women and/or transgender individuals in SSA. DATA EXTRACTION AND SYNTHESIS: Articles were screened and extracted twice and categorised by use of an intersectional approach. Study designs and stigma types were described quantitatively and findings on intersectional stigma were thematically analysed. RESULTS: Of 173 articles on HIV-related stigma among SGM in SSA included in this review, 21 articles (12%) applied an intersectional lens. The most common intersectional stigmas investigated were HIV and same-sex attraction/behaviour stigma and HIV, same-sex attraction/behaviour and gender non-conformity stigma. Intersectional stigma drivers, facilitators and manifestations were identified across individual, interpersonal, institutional and societal socioecological levels. Intersectional stigma impacts HIV vulnerability by reducing HIV prevention and treatment service uptake, worsening mental health and increasing exposure to HIV risk factors. CONCLUSION: Intersectional approaches are gaining traction in stigma research among SGM in SSA. Future research should prioritise quantitative and mixed methods investigations, diverse populations and intervention evaluation.

Equitable bivalent booster allocation strategies against emerging SARS-CoV-2 variants in US cities with large Hispanic communities: The case of El Paso County, Texas.

COVID-19 is a disease that disproportionately impacts the Hispanic population, due to the prevalence of certain risk factors and the high number of essential workers in this community. In this work, we analyze the vaccination strategies that would minimize the COVID-19 health disparities in El Paso County, TX, in the context of the emergence of a new highly transmissible and immune-escaping SARS-CoV-2 variant. We stratify an age-structure stochastic SEIR model that tracks the evolution of immunity derived from infections and vaccination according to Hispanic vs non-Hispanic ethnicity and parameterize it to the demographic, health and immunization data of El Paso County, TX. After fitting the model, the results show that increasing vaccination with bivalent boosters by five-fold in anticipation of highly transmissible and immune escaping variants would decrease the cumulative hospital admissions and mortality from Mar 1, 2023, to Dec 31, 2023, by 62.72% and 61.41%, respectively. Further, our projections reveal that the disproportionate impact on the Hispanic community would be eliminated if approximately half of the doses that are given to the non-Hispanic group according to the equal distribution, would be re-allocated to the Hispanic population. Our findings can guide public health officials in US cities with large Hispanic communities and help them design vaccination strategies that minimize COVID-19 health disparities caused by emerging variants using specific vaccination strategies.

HIV Education, Empathy, and Empowerment (HIVE3): A Peer Support Intervention for Reducing Intersectional Stigma as a Barrier to HIV Testing among Men Who Have Sex with Men in Ghana.

Men who have sex with men (MSM) in Ghana remain at heightened risk of HIV infection, and face challenges in accessing HIV prevention and care services. Previous research in Ghana shows that MSM face intersectional stigma across ecological levels (family, peers, healthcare settings, and community level) and the criminalization of same-gender sexual behaviors in the country. To protect their wellbeing from exposure to stigma, many MSM avoid interactions with healthcare systems and services, which inadvertently inhibits their opportunities for early detection and treatment of HIV. Consequently, MSM in Ghana carry a disproportionate burden of HIV prevalence (18%) compared to the general population (2%), highlighting the need for culturally relevant processes in HIV/STI prevention, and care communication to optimize sexual health and wellness among MSM in Ghana. To this effect, we collaborated with community partners to use the Assessment, Decision, Adaptation, Production, Topical Experts, Training, Testing (ADAPT-ITT) model to modify a theory-driven smartphone-based peer support intervention to enhance its focus on intersectional stigma reduction, and improve HIV health-seeking behaviors among MSM, including HIV testing and linkage to care. We used the Dennis Peer Support Model to develop the peer support components (emotional, informational, and appraisal support) to increase peer social support, decrease social isolation, and minimize intersectional stigma effects on HIV-related healthcare-seeking behaviors. This paper shows the preliminary acceptability and effectiveness of employing culturally relevant techniques and communication strategies to provide secure peer support to improve HIV prevention and care among key populations in highly stigmatized environments.
