title: Unprotected receptive anal intercourse among men who have sex with men in Brazil.
abstract: The aim of this study was to assess factors associated with unprotected receptive anal intercourse (URAI) in a sample of MSM recruited by respondent driven sampling in Brazil. Among 3,449 participants, 36.5 % reported URAI. Final logistic model indicated that living with a male partner, illicit drug use, having stable partnership, having sex with men only, having few friends encouraging condom use, and high self-perceived risk for HIV infection were characteristics independently associated with URAI. Intervention strategies should focus on the role of anal sex practices on HIV transmission, address illicit drug use, stigma and expansion of HIV testing and care.
