The Use of HIV Pre-exposure Prophylaxis Among Men Accessing Routine Sexual and Reproductive Health Services in South Africa

Abstract

PurposeThis study describes a cohort of men seeking oral pre-exposure prophylaxis (PrEP) services and explores their patterns of PrEP use within an implementation project seeking to integrate PrEP provision within sexual and reproductive health services in public health clinics in South Africa. MethodsRoutine program and survey data from 364 males initiated on oral PrEP between July 2020 and May 2022 were analyzed. PrEP use was examined, including time to first discontinuation and restart patterns. Factors associated with early PrEP discontinuation and PrEP restart were analyzed. ResultsDespite primarily focusing on access for adolescent girls and young women, PrEP services reached males with HIV prevention needs. PrEP use for ≤1 month (early discontinuation) was high at 58%; however, 18% restarted on PrEP, with 4% restarting repeatedly. Having depression symptoms was associated with early PrEP discontinuation (adjusted odds ratio [AOR]: 1.71, 95% CI [confidence interval]: 1.06–2.78). Those ≥25 years were less likely to discontinue early, as were those with a partner treated for a sexually transmitted infection in the preceding three months (AOR: 0.33, 95% CI: 0.13–0.84) and those who had been circumcised (AOR: 0.59, 95% CI: 0.36–0.96). Those 18–20 years old were less likely to restart PrEP than those ≥25 years (AOR: 0.43, 95% CI: 0.19–0.97), as were those whose partner's HIV status was unknown (AOR: 0.33, 95% CI: 0.12–0.88). DiscussionThis study identified interest and uptake of oral PrEP among an underrepresented population of predominantly heterosexual males seeking sexual and reproductive health services. It found high rates of early PrEP discontinuation, with a subset returning to restart PrEP. Further research is needed to determine whether these periods of PrEP use are associated with periods of HIV risk.
