Substance-using men who have sex with men (MSM) are among the groups at highest risk for HIV infection in the United States. We report the results of a randomized trial testing the efficacy of a small group sexual and substance use risk reduction intervention based on empowerment theory compared to an enhanced efficacious control condition among 515 high risk not-in-treatment MSM substance users. Effect sizes for sexual risk and substance use outcomes were moderate to large: HIV transmission risk frequency, d = 0.71 in the control versus 0.66 in the experimental group; number of anal sex partners, d = 1.04 versus 0.98; substance dependence symptoms, d = 0.49 versus 0.53; significant differences were not observed between conditions. Black MSM reduced their risks at a greater rate than White or Latino men. The findings point to a critically important research agenda to reduce HIV transmission among MSM substance users.
在美国，有性取向为男性且与男性发生性行为的男性（MSM）和其他一些群体，是感染艾滋病毒的高危人群。我们报告了一项随机试验的结果，该试验测试了一种基于赋权理论的小型群体性和物质使用风险降低干预措施的效果，与增强的有效对照组相比，该干预措施针对的是 515 名高危、未接受治疗的 MSM 物质使用者。性风险和物质使用结果的效果大小为中等至较大：HIV 传播风险频率，对照组为 0.71，实验组为 0.66；肛交伴侣人数，d = 1.04 对 0.98；物质依赖症状，d = 0.49 对 0.53；两组之间未观察到显著差异。黑人 MSM 比白人或拉丁裔男性降低风险的速度更快。这些发现为减少 MSM 物质使用者中的 HIV 传播指明了一个至关重要的研究议程。
