Abstract:

目的了解北京市大学在校生男男性行为者的HIV感染状况及其相关危险性行为。方法研究对象主要通过网络招募，采用自填式问卷调查。问卷内容包括人口学信息与艾滋病相关危险行为等。问卷完成后采集血液样本进行HW血清学检测。单因素分析采用f检验，多因素分析采用logistic回归。结果研究成功招募157人。平均年龄为(22．7--+2．8)岁，少数民族占12．1％，77．7％自我认同为同性恋。98．1％曾有肛交行为，73．9％报告肛交是常采用的性行为方式。157人中近6个月有58．6％发生过无保护肛交，有58．O％口交时从不使用安全套，其中59．2％存在多性伴(性伴数≥2)行为。近50．O％认为自己不可能感染HIV或者风险很小，检测发现HW阳性率为2．5％。logistic回归分析结果显示，曾与陌生人发生性行为(OR=13．10)、了解“肛交时做主动方比做被动方感染HIV风险小”(OR=3．37)以及曾去同性恋酒吧(0R=2．49)是近6个月发生多性伴行为的独立危险因素。结论大学在校生男男性行为者无保护肛交和多性伴行为较普遍。亟需开展有针对性的干预活动，预防HIV在该人群中传播。
