目的了解温州市男男性行为人群(MSM)的艾滋病知识知晓情况、高危行为特征及艾滋病病毒(HIV)感染状况,为今后制定有效的干预措施和防控政策提供参考。方法在知情同意的前提下,由经过培训的调查员分别在2011-2013年的4-6月,对MSM进行匿名问卷调查及抽血检测,采用Logistic回归分析。结果共调查MSM 1204人,艾滋病防治知识总知晓率84.3%(1015人),HIV抗体、梅毒抗体检测阳性率分别为7.4%(89人)、9.3%(112人)。单因素分析显示,艾滋病知识总知晓率与HIV、梅毒抗体阳性率存在分离现象(P>0.05),非条件Logistic回归多因素分析显示:MSM 1年内接受过咨询或宣传、同伴员宣传、6个月内与同性发生过商业性行为、调查时间,与艾滋病知识总知晓率差异有统计学意义(P<0.05)。75.7%的调查对象(911人)6个月内与男性发生过肛交,32.0%的调查对象(385人)同时拥有男女性伴,17.6%MSM(212人)提供过有偿性服务,5.3%的MSM(48/911)每次与男性发生肛交时都使用安全套。结论 MSM存在同时有男女性伴、高危性性行为等感染HIV的潜在危险,同伴教育、咨询、宣传有利于提高艾滋病知识知晓率,知晓率与HIV阳性率存在分离现象,提高知晓率可减少商业性性行为的发生。
