The contribution of injection drug use to HIV risk among men who have sex with men (MSM) is understudied. MSM infected with HIV within the prior 12 months completed a questionnaire assessing sociodemographic, sexual, drug use, and social factors. Analyses were performed to identify factors associated with lifetime history of injection drug use. Among 212 participants, the mean age was 33.8 years, 72% were White, 89% had attended college, and 9.4% reported ever injecting drugs. In multivariable logistic regression analysis, ever trading sex and using methamphetamine during sex with at least one of their last three partners were associated with injection drug use. Adjusting for these variables, in separate models, ever perpetrating violence against others (Adjusted Odds Ratio [AOR] = 3.16), having physically abusive sexual partners (AOR = 3.08), or physically abusing sexual partners (AOR = 10.17) were significantly (P < 0.05) associated with injection drug use. These findings suggest that violence is more common among MSM who inject drugs, which should be considered in HIV prevention efforts.
注射吸毒对男男性行为者（MSM）中 HIV 风险的影响研究不足。在过去 12 个月内感染 HIV 的 MSM 完成了一份评估社会人口统计学、性行为、吸毒和社会因素的问卷。进行了分析以确定与终身注射吸毒史相关的因素。在 212 名参与者中，平均年龄为 33.8 岁，72%为白人，89%上过大学，9.4%报告曾注射过毒品。在多变量逻辑回归分析中，与过去三个性伴侣中的至少一个进行过性交易和在性行为中使用冰毒与注射吸毒有关。在单独的模型中，调整这些变量后，曾经对他人实施暴力（调整后的优势比 [AOR] = 3.16）、有身体虐待性伴侣（AOR = 3.08）或身体虐待性伴侣（AOR = 10.17）与注射吸毒显著相关（P < 0.05）。这些发现表明，注射吸毒的 MSM 中暴力行为更为常见，在 HIV 预防工作中应考虑这一点。
