Commercial sex venues (CSVs) and public sex environments (PSEs) offer men who have sex with men (MSM) sexual privacy and anonymity. Sociodemographic characteristics (e.g., race/ethnicity, sexual identity, age, HIV status) are correlated with individuals' choice of sexual venue, potentially suggesting environmental associations with both sociodemographics and sexual risk. From March 2005 through March 2012, 1298 substance-using MSM provided information on their most recent sexual encounter; iterative logit models estimated associations between sociodemographics and sexual venue, and/or whether sexual venue was associated with sexual risk-taking while controlling for sociodemographics. More than a third of participants' most recent sexual encounters took place in either a PSE (23.0%) or a CSV (11.3%); anonymous, HIV-serodiscordant, and/or sex while on methamphetamine and/or marijuana was significantly more likely to occur in CSVs/PSEs than in a private location, even when controlling for sociodemographics. Findings demonstrate that socioenvironmental factors were associated with sexual risk-taking among high-risk, urban MSM.
商业性性交易场所（CSV）和公共性性交易环境（PSE）为男男性行为者（MSM）提供了性隐私和匿名性。社会人口学特征（如种族/民族、性取向、年龄、艾滋病毒感染状况）与个人对性交易场所的选择相关，这可能表明环境与社会人口学特征以及性风险之间存在关联。从2005年3月到2012年3月，1298名使用毒品的男男性行为者提供了他们最近一次性接触的相关信息；迭代逻辑模型估计了社会人口学特征与性交易场所之间的关联，以及在控制社会人口学特征的情况下，性交易场所是否与性冒险行为相关。超过三分之一的参与者最近一次性接触发生在公共性性交易环境（23.0%）或商业性性交易场所（11.3%）；即使在控制社会人口学特征的情况下，在商业性性交易场所/公共性性交易环境中，匿名、艾滋病毒血清学不一致的性行为，以及/或者在使用甲基苯丙胺和/或大麻时发生的性行为，比在私人场所发生的可能性显著更高。研究结果表明，社会环境因素与高危城市男男性行为者的性冒险行为相关。
