目的了解北京市男男性接触者（MSM）无保护肛交（UAI）的发生率及影响因素。方法于2009年9月至10月，采用调查者驱动抽样（RDS）方法，对500名男男性行为者进行调查。一个计算机辅助的，由访谈者管理的问卷被用来收集信息，包括人口统计学，性行为和安全套使用的社会规范（一个比例数字）。采用RDSAT和SAS软件对变量进行评价。结果调查对象平均年龄30.6岁，汉族占96.0%，高中及以上文化程度占68.5%。未婚者占72.8%，自认为同性恋者占61.7%，近6个月内有1名以上男性伴侣者占61.2%，UAI患病率为42.0%。UAI的显著双变量预测因素包括安全套使用社会规范评分、与男性性伴侣肛交的角色、过去6个月内男性性伴侣的数量和饮酒量。在多变量分析中，UAI与较高的安全套使用社会规范评分（AOR = 1.2，95%CI：1.1 - 1.3）、接受性肛交（AOR = 2.0，95%CI：1.3 - 3.2）和过去12个月内每月饮酒超过3次（AOR = 1.6，95%CI：1.1 - 2.5）相关。结论北京市男男性行为人群中UAI的流行率较高，提示如何使安全套的使用成为一种社会规范，并加以推广。
OBJECTIVE To understand the prevalence of and factors associated with unprotected anal intercourse (UAI) among men who have sex with men (MSM) in Beijing. METHODS Five hundred MSM were recruited for a survey using Respondent Driven Sampling (RDS) method, from September to October in 2009. A computer-assisted, interviewer-administered questionnaire was used to gather information including demographics, sexual behaviors and condom use social norms (a scaled number). Variables were evaluated by using RDSAT and SAS software. RESULTS Mean age of the participants was 30.6 years, with 96.0% of them as Han ethnicity and 68.5% having had at least high school or higher education level. 72.8% of them were unmarried, with 61.7% of them identified themselves as homosexual, 61.2% had > 1 male partners in the past six months, and the prevalence of UAI was 42.0%. Significant bivariate predictors of UAI would include condom use social norms score, role for anal sex with male sex partner, number of male sexual partners in the past 6 months and amount of alcohol consumed. In multivariable analysis, UAI was associated with a higher condom use social norms score (AOR = 1.2, 95%CI: 1.1 - 1.3), receptive anal intercourse (AOR = 2.0, 95%CI: 1.3 - 3.2) and drinking alcohol more than 3 times per month in the past 12 months (AOR = 1.6, 95%CI: 1.1 - 2.5). CONCLUSION The prevalence of UAI was high in the MSM community in Beijing, suggesting that efforts should be targeting on how to make the condom use a social norm and being promoted.
