目的了解北京市朝阳区男男性行为者(MSM)中艾滋病相关知识、性行为和HIV感染情况,为制定干预措施提供科学依据。方法以男男性行为者作为种子,采用滚雪球的方法招募研究对象,通过问卷对男男性行为者进行性行为调查。用ELISA方法对研究对象进行HIV、梅毒的血清学检测。结果 1 008名MSM人群年龄轻、学历高、未婚者居多。对艾滋病防治知识知晓率为87.8%,不同职业、不同文化程度的调查对象艾滋病相关知识的知晓情况差异有统计学意义(P<0.05)。其中56.2%的调查对象同时有男女性伴,女性临时性伴中一夜情和/或网友/客人的占72.2%,且安全套从不使用率高达28.8%。1 008人中HIV感染率5.8%,梅毒感染率16.5%。结论 MSM人群对艾滋病/性病存在明显的知识、行为分离情况,性行为的安全套使用率低,对大专以上文化程度的MSM人群宣传干预是今后艾滋病防控重点。
