Among men who have sex with men (MSM), acute alcohol consumption is associated with higher rates of condomless anal intercourse, which is linked with a greater likelihood of exposure to HIV and other sexually transmitted infections. While pre-exposure prophylaxis (PrEP) to prevent HIV infection has become more widespread in this population in recent years, so too have concerns that PrEP uptake may be associated with health risk behaviors. This study investigated differences in sexual behaviors and drug use habits between PrEP users and nonusers in a sample of moderate- and heavy-drinking MSM. Results indicated that PrEP use was associated with riskier sexual practices, weaker self-regulatory cognitions related to condom use, and more frequent illicit drug use. These findings suggest that moderate-and heavy-drinking MSM who use PrEP may comprise a unique risk group that could benefit from targeted counseling or other interventions to reduce their risk of negative health consequences.

暴露前预防（PrEP）的使用与中度和重度饮酒的MSM中的健康风险行为有关

在与男性发生性关系（MSM）的男性中，急性饮酒与无避孕套的肛门性交比例较高有关，这与暴露于HIV和其他性传播感染的可能性更大有关。尽管近年来预防暴露前预防（PrEP）预防HIV感染在该人群中变得越来越普遍，但也有人担心PrEP摄入可能与健康风险行为有关。这项研究调查了中度和重度饮用MSM样本中PrEP使用者和非使用者之间性行为和药物使用习惯的差异。结果表明，使用PrEP与危险的性行为，与使用安全套有关的较弱的自我调节认知以及更频繁的非法药物使用有关。
