Abstract summary 

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.
