Psychological Problems Mediate the Relationship Between Minority Stress and HIV Sexual Risk Among Nigerian Men Who Have Sex with Men: Testing the Minority Stress Model.

Gay, bisexual, and other men who have sex with men (GBMSM) in Nigeria bear a disproportionately higher burden of HIV. Meyer's minority stress theory posits that social stress due to the discrimination, violence, and stigma experienced by lesbian, gay, and bisexual men and women (LGBs)—due to their sexual orientation—may contribute to psychological problems, including mental health problems, substance use, and HIV sexual risk-taking. Between March and June 2019, we recruited 406 GBMSM from four states in Nigeria (Abuja, Delta, Lagos, and Plateau) to complete a cross-sectional survey at local community-based organizations. We utilized structural equation modeling to test whether psychological problems and substance use mediated the relationship between minority stress and HIV sexual risk-taking (condomless anal sex and number of sexual partners) among GBMSM in Nigeria. Minority stress (β = 0.60, 95% CI: 0.44–0.72, p ≤.001), substance use (β = 0.43, 95% CI: 0.27–0.59, p =.004), and psychological problems (β = 0.35, 95% CI: 0.28–0.45 p =.012) had moderate associations with HIV sexual risk-taking. We found that psychological problems mediated the relationship between minority stress and HIV sexual risk-taking. Interventions focused on addressing psychological problems may help mitigate the effects of minority stress on HIV sexual risk-taking among GBMSM in Nigeria. [ABSTRACT FROM AUTHOR]
