我们评估了中国北京男男性行为者（MSM）的HIV感染率、相关行为和危险因素。在2009年，我们招募了500名男男性接触者，使用应答者驱动抽样（RDS）进行生物和行为调查。检测血清标本的HIV和梅毒感染标志物。计算机辅助个人访谈（CAPI）管理的问卷调查收集的信息，包括人口特征，性行为，艾滋病毒检测和社会规范有关的安全套的使用。调整后的HIV感染率为8.0%，梅毒感染率为22.0%。艾滋病毒检测和披露率很低;只有39.3%的人在过去12个月内进行了艾滋病毒检测，49.7%的人知道自己的艾滋病毒状况，22.8%的人知道最后一个男性伴侣的艾滋病毒状况。艾滋病毒感染与梅毒有关，曾经与女性发生性关系，不知道最近男性伴侣的艾滋病毒状况，并且在过去12个月内从未购买避孕套。对使用安全套的积极社会规范的大力支持，预示着艾滋病毒感染率的降低。与最近类似设计的调查相比，艾滋病病毒在北京的男男性接触者中继续迅速传播。我们的研究结果确定了干预点，如果及时解决，仍然可能改变流行病的进程，包括促进艾滋病毒检测和伴侣披露，梅毒控制，特别是改变安全套使用的社会规范。
We assessed HIV prevalence and associated behaviors and risk factors among men who have sex with men (MSM) in Beijing, China. Five hundred MSM were recruited for a biological and behavioral survey using respondent-driven sampling (RDS) in 2009. Serologic specimens were tested for markers of HIV and syphilis infection. A computer-assisted personal interview (CAPI) administered questionnaire gathered information including demographic characteristics, sexual behaviors, HIV testing, and social norms concerning condom use. The adjusted HIV prevalence was 8.0%, syphilis 22.0%. HIV testing and disclosure was low; only 39.3% had HIV tested in the past 12 months, 49.7% knew their own HIV status and 22.8% knew their last male partner's HIV status. HIV infection was associated with syphilis, ever having sex with a woman, not knowing the HIV status of the most recent male partner, and never buying condoms in the past 12 months. Stronger endorsement of positive social norms around condom use strongly and predicted lower prevalence of HIV infection. Compared to surveys of similar design in the recent past, HIV continues to spread rapidly among Beijing's MSM. Our results identify points of intervention that, if addressed in time, may still alter the course of the epidemic including the promotion of HIV testing and partner disclosure, syphilis control and particularly changing social norms around condom use.
