    Abstract:
    Objective: To understand the prevalence of facility-based HIV testing and its associated factors among men who have sex with men (MSM) in Beijing city. Methods: An application-based cross-sectional survey was employed to understand HIV site test situation and associated factors. The survey was carried out from May 14(th) to 21(st), 2016. Users of a smart phone application for gay dating were recruited and those eligible for this survey were investigated with an online self-administered questionnaire. Information of demographics, sexual behaviors, facility-based HIV testing history and recreational drug abuses were collected. The multivariate logistic regression was used to make comparison among different groups and assess associated factors. Results: A total of 7 494 participants were enrolled in the survey with mean age of (28.81 ± 7.38) years, 87.14% (6 530/7 494) sought sexual partners through internet. The proportion of facility-based HIV testing in 1 year was 42.55% (3 189/7 494), MSM who were 25-29 years had higher proportion of facility-based HIV testing in 1 year, the proportion was 45.56%(1 104/2 423). Among MSM who could insist in using condom during anal sex (50.46% (1 539/3 050)), the proportion of HIV site testing in 1 year was higher. The MSM who reported seeking healthcare for symptoms of a sexually transmitted infections (STIs) in the past year or ever using recreational drug had higher proportion of facility-based HIV testing, the proportions were 56.81% (409/720) and 52.00% (1 340/4 917), respectively. Compared with alone cohabitation, cohabitating was associated with decreased odds of HIV facility-based testing in past 1 year(odds ratio (OR)= 0.79, P<0.001). Compared with homosexual sexual orientation, bisexual sexual orientation was associated with decreased odds of facility-based HIV testing (OR=0.83, P=0.004). With the increasing of number of male anal sex partners, the odds of HIV facility-based testing was increasing (OR=1.31, P<0.001) But with the decreasing of the frequency of condom using with male anal sex partners, the odds of facility-based HIV testing was decreasing (OR=0.85, P=0.014). Using recreational drugs (OR=1.36, P<0.001) and seeking healthcare for symptoms of a STI in the past 1 year (OR=1.73, P<0.001) were associated with decreased odds of HIV site testing. Conclusion: MSM in Beijing had lower proportion of facility-based HIV testing in past 1 year. Multiple anal sex partners, using recreational drugs, seeking healthcare for symptoms of a STI in the past year, cohabitating, bisexual sexual orientation, and lower frequency of condom using with male anal sex partners were associated with the odds of HIV facility-based testing in past 1 year. 目的：分析北京市部分男男性行为人群（MSM）近1年HIV检测点检测情况及影响因素。方法：于2016年5月14—21日，以某男男同性恋交友软件的注册用户为调查对象。纳入18岁及以上，软件账号的注册地及调查期间全球卫星定位系统显示位置均为北京，截至调查当日发生过男男同性性行为、自报HIV检测结果为阴性或未知者，以及知情同意者，共8 763名。采用自行设计问卷对其进行调查（包括基本特征、自报告最近3个月性行为情况、HIV检测点检测情况、新型毒品使用情况、自报性病检测情况等），最终收集有效问卷7 494份。采用多因素二分类非条件logistic回归模型分析MSM近1年检测点检测HIV的影响因素。结果： 7 494名调查对象的年龄为（28.81±7.38）岁，通过网络寻找性伴者占87.14%（6 530/7 494）。近1年检点检测HIV的比例为42.55%（3 189/7 494），其中25~29岁者近1年HIV检测点检测率较高，为45.56%（1 104/2 423）；过去3个月中，与2个及以上性伴发生同性肛交性行为者近1年HIV检测点检测率较高，为52.94%（1 306/2 467）；过去3个月发生过同性肛交行为的调查对象中，坚持一直使用安全套者近1年HIV检测点检测率较高，为50.46%（1 539/3 050）；过去1年因性病症状去就诊者近1年HIV检测点检测率较高，为56.81 % （409/720 ）；使用过新型毒品者近1年HIV检测点检测率较高，为52.00%（1 340/4 917 ）。与独自居住者相比，非独自居住者近1年检测点检测HIV的可能性较小（OR=0.79 ，P<0.001）；与性取向为同性恋者相比，双性恋者检测的可能性较低（OR=0.83，P=0.004）；随着过去3个月同性肛交性伴数的增加，检测的可能性增加（OR= 1.31 ，P<0.001），但却随着肛交时安全套使用频率的降低而降低（OR=0.85，P=0.014）；曾使用过新型毒品者比未使用过的MSM检测点检测HIV的可能性高（OR=1.36，P<0.001）；过去1年曾因性病症状就诊者比未就诊者检测点检测HIV的可能性高（OR=1.73 ，P<0.001）。结论：北京市MSM近1年内HIV检测比例较低；最近3个月多性伴、曾使用过新型毒品、过去1年曾因性病症状就诊、非独居、性取向为双性恋和低安全套使用频率均与MSM近1年内HIV检测点检测存在相关性。.
