In Brazil, pre-exposure prophylaxis (PrEP) is currently available for gay, bisexual, and other men who have sex with men. As PrEP use depends on an individual's perceived risk, we explored pathways by which potentially modifiable behaviors lead to high perceived HIV risk. Using online surveys (N = 16,667), we conducted a path analysis on the basis of ordered sequences of multivariate logistic regressions. High perceived HIV risk was low (26.3%) compared to condomless receptive anal sex (41.4%). While younger age increased the odds of binge drinking and of condomless receptive anal sex, it was associated with decreased odds of high perceived HIV risk. In contrast, use of stimulants increased the odds of condomless receptive anal sex and of high perceived HIV risk. Our results suggest that binge drinking and use of stimulants are key points in different pathways to high-risk sexual behavior and may lead to different perceptions of HIV risk. |
