Men who have sex with men (MSM) have a high prevalence of hazardous alcohol consumption. While network-level characteristics such as social network size have been indicated as upstream determinants of alcohol use in general population samples, no studies have examined factors associated with alcohol using network size (ANS), among MSM.This secondary analysis examined demographic, substance use, and sexual behavior correlates of ANS using data from a diverse sample of alcohol-using MSM in San Francisco ( = 252). Associations were calculated using multivariable negative binomial regression, adjusting for age, race, education, and employment.The median ANS was 10. Factors associated with larger ANS in multivariable analyses included identifying as Hispanic/Latino, having completed a college education or higher, having a higher Alcohol Use Disorders Identification Test (AUDIT) score, having a greater number of sexual partners, polysubstance use, and being unaware of one's own HIV status. Factors associated with smaller ANS included being between 18 and 24 years of age, reporting a low income, and having any lifetime history of injection drug use.For MSM, ANS was associated with increased likelihood of hazardous alcohol use, as well specific individual-level substance use and sexual risk behaviors. These results highlight the role of ANS in hazardous alcohol consumption and sexually transmitted infection transmission among MSM. These results also indicate ways that research and intervention programs aimed at reducing alcohol use among MSM might be improved through network-based recruitment or engagement. Finally, these results suggest the need for further research on HIV-unknown MSM.
男男性行为者（MSM）中存在较高比例的危险饮酒行为。尽管网络层面的特征，如社交网络规模，已被指出是一般人群样本中饮酒行为的上游决定因素，但尚无研究调查与 MSM 群体的饮酒网络规模（ANS）相关的因素。本二次分析使用来自旧金山多样化的饮酒 MSM 样本（n=252）的数据，考察了 ANS 与人口统计学、物质使用和性行为的相关性。采用多变量负二项回归，调整年龄、种族、教育和就业等因素后，计算了关联。中位数 ANS 为 10。多变量分析中与更大的 ANS 相关的因素包括认定为西班牙裔/拉丁裔、完成大学教育或更高学历、酒精使用障碍识别测试（AUDIT）得分较高、性伴侣数量较多、多种物质使用以及不知道自己的 HIV 状况。与较小的 ANS 相关的因素包括年龄在 18 至 24 岁之间、报告收入较低以及有任何终生注射毒品使用史。对于 MSM 而言，ANS 与危险饮酒行为以及特定的个体物质使用和性风险行为的可能性增加相关。这些结果突出了 ANS 在 MSM 中危险饮酒和性传播感染传播中的作用。这些结果还表明，旨在减少 MSM 饮酒行为的研究和干预计划可以通过基于网络的招募或参与来得到改善。最后，这些结果表明需要进一步研究 HIV 未知的 MSM 群体。
