在俄罗斯，大多数早期艾滋病毒感染者是男男性行为者（MSM）。尽管如此，以及目前艾滋病毒在全球男男性行为者中的死灰复燃，几乎没有系统的工作来评估目前的艾滋病毒风险。我们对俄罗斯男男性接触者中的艾滋病病毒和相关危险行为进行了快速评估。在莫斯科和彼得堡的男男性行为者中进行了一项匿名的横断面研究（2008年1月）。参与者由当地非政府组织合作伙伴通过同行招募招募，进行了简短的行为调查，并提供快速，口服艾滋病毒筛查。与HIV感染相关的因素采用Logistic回归进行评估。共有401名参与者入组。两个城市的艾滋病毒流行率相当（莫斯科为6.0%，彼得堡为5.5%）。大约一半（49.3%）年龄在25岁以下，75.1%的男性报告了无保护的肛交（UAI），21.5%的男性报告在过去12个月内进行了无保护的交换性行为。年龄在18-22岁的最年轻男男性行为者中艾滋病毒感染率最高（7.7%）。从未检测过HIV（AOR = 6.2; 95% CI：1.8，21.9）和曾经注射毒品（AOR = 11.3; 95% CI：2.6，50.4）与HIV感染独立相关。我们发现，在莫斯科和彼得堡的男男性行为者中，特别是在最年轻的男性中，艾滋病毒的总体流行率很高。大多数男性报告了持续的高风险行为，表明有进一步传播的可能性。艾滋病毒预防工作需要特别关注俄罗斯的城市男男性行为者，鼓励检测，并针对注射风险来解决这一流行病。
The majority of early cases of HIV in Russia were among men who have sex with men (MSM). Despite this and the current resurgence of HIV among MSM globally, little systematic work has been done to assess current HIV risks. We conducted a rapid assessment of HIV and associated risk behaviors among MSM in Russia. An anonymous, cross-sectional study was performed among MSM in Moscow and St. Petersburg (January 2008). Participants were enrolled by local NGO partners via peer-recruitment, underwent a brief behavioral survey, and were offered rapid, oral HIV screening. Factors associated with HIV infection were assessed using logistic regression. A total of 401 participants were enrolled. HIV prevalence was comparable in the two cities (6.0% in Moscow, 5.5% in St. Petersburg). Approximately half (49.3%) were under age 25, 75.1% of all men reported unprotected anal intercourse (UAI), and 21.5% reported engaging in unprotected exchange sex in the prior 12 months. HIV infection was the highest (7.7%) among the youngest MSM, those aged 18-22 years. Never having tested for HIV (AOR = 6.2; 95% CI: 1.8, 21.9) and ever injecting drugs (AOR = 11.3; 95% CI: 2.6, 50.4) were independently associated with HIV infection. We found significant overall HIV prevalence among MSM in Moscow and St. Petersburg, particularly among the youngest men. The majority of men reported ongoing high-risk behaviors, indicating the potential for further spread. HIV prevention efforts need to specifically focus on urban MSM in Russia, encourage testing, and target injection risks to address this epidemic.
