摘要
目的了解北京市男男性接触者人群(MSM)行为特征、艾滋病病毒(HIV)感染状况及影响因素。方法利用北京市2009-2013年MSM人群监测数据进行HIV感染的单因素χ2检验和多因素logistic回归分析,P<0.05为差异有统计学意义。结果本研究共调查2 992例MSM,HIV、梅毒抗体阳性检出率分别为7.72%(231/2 992)和11.11%(264/2 376)。艾滋病基本知识总体知晓率为94.02%(2 813/2 992)。最近1年接受过安全套宣传和发放/艾滋病咨询与检测的比例为74.36%(2 225/2 992),接受过同伴教育的比例为35.93%(1 075/2 992),做过艾滋病检测的比例为55.08%(1 648/2 992)。多因素分析显示,在本地居住时间≤1年(OR=1.779)、最近6个月与同性发生肛交性行为时未坚持使用安全套(OR=1.474)、最近6个月与同性发生过商业性行为(OR=1.826)、最近1年未做过艾滋病检测(OR=1.607)、梅毒检测结果阳性(OR=2.658)是MSM人群感染的危险因素。结论北京市MSM人群中HIV感染率较高,存在同性商业性行为和安全套使用率低等危险因素,应采取有效的干预措施,降低HIV在MSM中的传播。
Objective To understand HIV infection and its influencing factors among men who have sex with men（MSM）in Beijing. Methods Surveillance data of MSM in Beijing from 2009 to 2013were collected and analyzed by Chi-square test and multivariate logistic regression analysis. Results Totally,2 992 MSM were interviewed from 2009 to 2013and 7.72%（231/2 992）were HIV antibody positive and 11.11%（264/2 376）were positive for syphilis.The overall awareness rate of HIV/AIDS knowledge was 94.02%（2 813/2 992）.The percentage of MSM receiving free condom and VCT was 74.36%（2 225/2 992）in the most recent year,which was higher than those receiving peer education（35.93%）and HIV testing（55.08%）.Multivariate logistic regression analysis showed that being in Beijing less than 1year（OR=1.779）,having unprotected anal sex in recent 6months（OR=1.474）and having commercial sex with males（OR=1.826）,not receiving HIV testing in the most recent year（OR=1.607）and syphilis infection（OR=2.658）were risk factors associated with HIV infection. Conclusions The prevalence of HIV among MSM was relatively high especially those having commercial sex with males and having unprotected sex.Specific and effective intervention should be strengthened to avoid HIV spreading among MSM.
