目的了解男男性接触者(MSM)艾滋病防治知识的知晓率和高危行为的发生率,为疫情预测和干预工作提供依据。方法采用国家统一的行为监测问卷,通过多种方法进行匿名监测,包括直接到同性恋酒吧、桑拿浴池、公园等同性恋聚集地进行调查,以及通过滚雪球的方法和网络宣传吸引人群到自愿咨询检测点进行调查。结果(1)25.55%的监测对象认为自己有感染艾滋病的风险,不同来源的监测对象自认为有感染风险的比例不同(x2=40.45,Ρ<0.0001);基本知识完全答对率为40.82%,不同来源的监测对象答对率差异有统计学意义(x2=15.71,Ρ=0.0013);65.75%的监测对象知道做艾滋病检测的地方,不同来源的监测对象间亦有统计学差异(x2=8.01,Ρ=0.0458)。(2)67.40%的监测对象在半年内有过同性性伴,性伴数的中位数为3人;最近6个月有同性性行为的监测对象中,3.09%承认通过付钱的方式得到过男性提供的性服务,1.54%承认为了得到钱,为男性提供过性服务;11.51%的监测对象在半年内有女性伴侣。(3)84.89%的监测对象为防艾滋病愿意使用安全套。最近6个月肛交行为中,11.20%的人从未使用安全套,每次都使用的占45.56%;最近一次肛交时,使用安全套的比例为56.76%,未用安全套的比例为29.34%。结论MSM群体对感染艾滋病的风险认识不足,感染艾滋病的危险行为还广泛存在,应该加强对浴室和公园等场所MSM人群的干预。
Objective To understand the awareness of HIV / AIDS and the incidence of high-risk behaviors in MSM and to provide a basis for the prediction and intervention of SARS. Methods A unified national behavioral monitoring questionnaire was used to conduct anonymous monitoring through a variety of methods, including direct gay bars, sauna pools, homosexuality in parks, and the use of snowballs and online publicity to attract people to voluntary counseling and testing sites survey. Results (1) 25.55% of the respondents considered themselves as having the risk of contracting AIDS, and the proportion of subjects from different sources considered themselves at different risk of infection (x2 = 40.45, P <0.0001). The completeness of basic knowledge was 40.82% (X2 = 15.71, P = 0.0013); 65.75% of the respondents knew about HIV testing and there were significant differences among the monitoring subjects from different sources (x2 = 8.01, P = 0.0458). (2) 67.40% of the respondents had homosexual partners in half a year, the median number of partners was 3; 3.09% of those who had homosexual behaviors in the recent 6 months admitted that they were paid by way of payment 1.54% admitted that they had provided sexual services to men in order to get money; 11.51% of them had female partners within six months. (3) 84.89% of the respondents are willing to use condoms to prevent AIDS. In the last 6 months, 11.20% of people never used condoms during the last 6 months, accounting for 45.56% of the total. In the last anal sex, 56.76% used condoms and 29.34% did not. Conclusion The MSM population is not aware of the risk of HIV infection and the risk of HIV infection is widespread. Intervention should be strengthened for MSM in bathroom and parks.
