Men who have sex with men (MSM) are substantially impacted by HIV/AIDS in the United States. Alcohol use is frequently studied as a predictor of sexual risk in MSM, but findings for this association have been mixed. Developmental differences in this effect may help to explain equivocal findings. 143 MSM (analytic sample 137) ages 16-40 completed weekly diaries of sexual encounters and associated situational factors for 12 weeks. Analyses were conducted with Hierarchical Linear Modeling. Alcohol use before sex was not associated with sexual risk across all participants. Participant age moderated this effect; alcohol use before sex was associated with increased odds of sexual risk in younger MSM only. These analyses expand on previous findings by utilizing a wider age range than most prior studies and adjusting for the effects of several theoretically-selected covariates. Young MSM are an important group to target for addressing alcohol use in the context of sexual behavior.
男男性行为者（MSM）在美国受到艾滋病毒/艾滋病的严重影响。饮酒经常被研究作为 MSM 性风险的预测因素，但这方面的研究结果却存在差异。这种影响的发展差异可能有助于解释结果的不确定性。143 名年龄在 16-40 岁的 MSM（分析样本 137 名）完成了为期 12 周的每周性接触和相关情境因素的日记。使用分层线性建模进行了分析。在所有参与者中，性行为前的饮酒与性风险无关。参与者年龄对此效应有调节作用；只有在年轻的 MSM 中，性行为前的饮酒与性风险的几率增加有关。这些分析利用比大多数先前研究更广泛的年龄范围，并考虑了几个理论上选择的协变量的影响，扩展了以前的研究结果。年轻的 MSM 是一个重要的群体，需要在性行为的背景下解决饮酒问题。
