在美国，与男性发生性关系的男性（MSM）占新感染艾滋病毒的一半以上。了解与从事危险性行为有关的因素对于制定有效的预防干预措施是很重要的。狂饮（≥1次≥5杯）是最常见的过度饮酒形式。本研究调查了当前饮酒者、艾滋病毒阴性或不知道自己的艾滋病毒状况的男男性接触者中酗酒与性风险行为之间的关系。利用2011年国家艾滋病行为监测系统和多变量泊松模型，我们评估了酗酒与当前饮酒者性风险行为之间的关系。给出了患病率（PR）和95%置信区间（CI）。总体而言，85%的男男性行为者目前是饮酒者，59%饮酒的男男性行为者在过去30天内报告了≥1次酗酒事件。在多变量模型中，酗酒与最后一次与hiv阳性或身份不明的伴侣进行无套肛交（CAI）相关（接受性：PR 1.3, 95% CI 1.1-1.6；插入性：PR 1.2, 95% CI 1.0-1.4），在最后一次性行为中以性换取金钱或毒品（PR: 1.4, 95% CI 1.1-1.7），在过去一年中有同时性伴侣（PR: 1.1, 95% CI 1.1-1.2），与非酗酒者相比，在过去一年中有更多的CAI伴侣（PR: 1.2, 95% CI 1.0-1.4）。减少酗酒的循证策略可以帮助减少男男性接触者的危险性行为。
Men who have sex with men (MSM) represent over half of new HIV infections in the United States. It is important to understand the factors associated with engaging in risky sexual behavior to develop effective prevention interventions. Binge drinking (≥5 drinks on ≥1 occasion) is the most common form of excessive alcohol consumption. This study examines the relationship between binge drinking and sexual risk behaviors among MSM who are current drinkers and who were either HIV-negative or unaware of their HIV status. Using the 2011 National HIV Behavioral Surveillance system and multivariable Poisson models with robust error estimates, we assessed the association between binge drinking and sexual risk behaviors among current drinkers. Prevalence ratios (PR) and 95% confidence intervals (CI) are presented. Overall, 85% of MSM were current drinkers, and 59% of MSM who drank reported ≥1 episode of binge drinking in the preceding 30 days. In multivariable models, binge drinking was associated with condomless anal intercourse (CAI) at last sex with an HIV-positive or unknown status partner (receptive: PR 1.3, 95% CI 1.1-1.6; insertive: PR 1.2, 95% CI 1.0-1.4), having exchanged sex for money or drugs at last sex (PR: 1.4, 95% CI 1.1-1.7), having concurrent partners in the past year (PR: 1.1, 95% CI 1.1-1.2), and having more CAI partners in the past year (PR: 1.2, 95% CI 1.0-1.4) compared to non-binge drinkers. Evidence-based strategies for reducing binge drinking could help reduce risky sexual behavior among MSM.
