Abstract BACKGROUND: Distinct homosexual and heterosexual HIV epidemics have previously been recognised in South Africa. However, linked HIV prevalence and self-reported sexual risk behaviour data have not been reported for men who have sex with men (MSM) in Cape Town since 1986. METHODS: We conducted a cross-sectional, anonymous, venue-based HIV risk behaviour and prevalence study of 542 self-identified MSM in greater Cape Town using a self-administered risk questionnaire and the OraSure testing device to asses HIV-1 prevalence. RESULTS: This sample had an overall HIV prevalence of 10.4\% (56/539). We found that self-identifying as gay, homosexual or queer (adjusted odds ratio (AOR) 4.5, 95\% confidence interval (CI) 1.0-20.0) and reporting ever having had a sexually transmissible infection diagnosis (AOR 4.3, 95\% CI: 2.3-8.3) were significantly predictive of testing HIV-1 positive, while reporting unprotected anal intercourse with a known HIV-negative partner (AOR 0.4, 95\% CI: 0.2-0.9) was significantly protective. CONCLUSION: These data suggest a mature epidemic with consistent high-risk taking among MSM in Cape Town, and significant associations of select self-reported risk behaviours and HIV-1 serostatus. There is a need for continued and robust HIV surveillance along with detailed risk behaviour trends over time to inform the development of targeted risk-reduction interventions for this population.
