Abstract

Background: The HIV/AIDS epidemic in Brazil remains concentrated in populations with high vulnerability to infection, including men who have sex with men (MSM). This indicates an urgent need to develop alternative HIV prevention strategies. Pre-exposure prophylaxis (PrEP) and home HIV test kits are two promising approaches that can be utilized in an optimal comprehensive HIV prevention package targeted toward MSM.
Objective: The purpose of this study was to assess willingness to use PrEP and home HIV testing and their associated factors among MSM in Brazil, and to evaluate knowledge of and attitudes toward these alternative HIV prevention methods.
Methods: Data were collected through an online men's health survey conducted in April 2011 and targeted toward MSM in Brazil. The primary outcomes measured were likelihood of using PrEP and likelihood of using home HIV test kits. Logistic regression was used to model participant characteristics with each outcome in bivariate and multivariate analyses.
Results: Overall willingness to use PrEP and home HIV test kits among MSM was high: 67% were extremely or very likely to take PrEP, and 90% agreed that they would be likely to use home HIV tests. Only 22% had previously heard of PrEP. MSM who were aware of PrEP were more willing to use it compared with men who were unaware (OR = 1.7, 95% CI: 1.04-2.6), and these odds increased with age. Men who had anal sex recently also had increased odds of being willing to use PrEP (OR = 3.1, 95% CI: 1.1-8.3). The only significant predictor of probable home HIV test use was age (P = 0.04). MSM reported overall high willingness to use at-home testing under various hypothetical situations (P < 0.05).
Conclusions: MSM in Brazil are likely to use PrEP and home HIV testing as alternative methods of HIV prevention. Additional research is needed to determine the optimal components of a tailored HIV prevention package utilizing a combination of interventions for MSM and other high-risk populations.
