摘要目的 探讨在不同主要场所进行性交往的男男性行为者(MSM)艾滋病高危行为状况.方法 采用定向抽样("滚雪球")法进行横断面调查,对9城市1834例MSM的有效匿名问卷进行分析,比较以互联网、酒吧、浴池为主要性交往场所MSM的艾滋病高危行为差异.结果 浴池组累计同性性伴数、累计同性肛交性伴数、累计同性口交性伴数、近6个月同性肛交性伴数(M 分别40、16、20、4例)均显著高于互联网组和酒吧组(P<0.01).浴池组28.9%的人近1年曾参加群交,显著高于酒吧组和互联网组(P<0.01);互联网组36.4%的人近1年性交出过血,显著高于酒吧组和浴池组(P<0.01).酒吧组和浴池组分别有14.9%和13.3%的人为性工作者,显著高于互联网组(P<0.01).浴池组分别有79.6%的人与MSM性交和45.3%的人与女性性交时使用过安全套,均低于其他两组(分别P<0.01,P<0.05).浴池组HIV感染率为4.2%,显著高于其他两组(P<0.01).结论 在不同主要性交往场所的MSM具有不同的艾滋病高危行为,需针对不同亚人群制定相应的艾滋病干预策略,尤应加强对浴池等场所的艾滋病干预.
