Factors Associated with Condomless Anal Sex and Absence of Pre-Exposure Prophylaxis (PrEP) Use Among Brazilian Men Who Have Sex with Men: A Cross-Sectional Study.

ABSTRACT:

Background

Men who have sex with men (MSM) in Brazil remain disproportionately affected by HIV. Combination prevention strategies, including Pre-Exposure Prophylaxis (PrEP), are critical, yet adherence remains a challenge. This study aimed to identify factors associated with the simultaneous practice of condomless anal sex and non-use of PrEP among Brazilian MSM.

Methods

A national cross-sectional study was conducted in 2020 via an online questionnaire disseminated on social media and dating apps. The outcome was defined as reporting condomless anal sex and no PrEP use in the previous year. Bivariate and multivariate logistic regression analyses were performed.

Results

Among 1357 MSM participants, a high proportion (69.4%) reported condomless anal sex without PrEP use
