【摘要】 目的了解安徽省MSM人群艾滋病知识水平、行为特征和HIV感染率,为制定防治策略提供依据。方法 2008-2009年每隔6个月分3次分别在合肥市和芜湖市招募MSM人群,进行面对面问卷调查,并采血样进行HIV、梅毒和丙肝检测。结果三轮共调查1641人(次),其中第一轮调查490人,第二轮调查443人,第三轮调查708人。大多数人参加调查是为了做艾滋病检测,了解自身感染状况,分别占72.4%、71.8%和74.7%。大多数自认为是"同性恋"或"双性恋",通过互联网联系寻找性伴。三轮艾滋病防治知识知晓率分别为89.4%、83.1%、89.3%(x~2=0.003,P=11.32)。每轮都有10%以上的人在最近6个月中从来没有使用安全套。买性和卖性现象明显,且坚持使用安全套的比例不高。每轮都有两三成的人有异性性行为,且不用安全套的比例很高。自报在最近1年,出现过性病相关症状的比例分别为13.9%、11.1%和10.6%。三轮调查的HIV阳性率分别为2.9%、1.6%和1.4%,梅毒阳性率11.0%、6.8%和8.8%。结论安徽省MSM人群艾滋病知识知晓率较高,但各知识点的知晓率不平衡;艾滋病病毒感染率不高,但艾滋病流行传播的隐患很大。需要采取针对性的健康教育措施,全面提高MSM人群的艾滋病防治知识水平;加大综合干预力度,改变危险行为,减少和消除艾滋病性病传播的隐患,以保持低HIV感染率水平。更多还原
