Acceptability of venue-based HIV testing and prevention interventions for men who have sex with transgender women and transgender women in Lima, Perú: a formative, qualitative study.

Background: Despite being at elevated risk for HIV, men who have sex with transgender women (MSTW) are an overlooked population in the global HIV response. Venue-based HIV interventions have previously had success reaching other HIV priority populations, including transgender women (TW). Similar approaches could be applied for MSTW.

Objective: To evaluate the prospective acceptability of venue-based HIV testing and prevention interventions for MSTW and TW in Lima, Peru.

Methods: In this exploratory qualitative study, we conducted in-depth interviews (IDI) and focus group discussions (FGD) with three types of participants: MSTW (7 IDIs, 1 FGD), TW (1 FGD), and owners of social venues frequented by MSTW/TW in Lima (2 IDIs). We elicited participants' attitudes and perceptions related to the following four hypothetical interventions delivered at social venues in Lima: rapid HIV testing; HIV self-test distribution; condom/lubricant distribution; and enrolment in a mobile app supporting HIV prevention. We performed a mixed deductive-inductive thematic analysis using the framework method, then applied the Theoretical Framework of Acceptability to classify the overall acceptability of each intervention.

Results: Condom/lubricant distribution and app-based HIV prevention information were highly acceptable among all participant types. The two HIV testing interventions had relatively lower acceptability; however, participants suggested this could be overcome if such interventions focused on ensuring discretion, providing access to healthcare professionals, and offering appropriate incentives.

Conclusions: Overall, MSTW and TW shared similar favourable attitudes towards venue-based HIV interventions. Venue-based outreach warrants further exploration as a strategy for engaging MSTW and TW in HIV prevention activities.
