摘　　要：目的了解我省男男性行为(MSM)人群的艾滋病知识水平、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个月在合肥市和芜湖市招募MSM人群,进行1次(共3次)面对面问卷调查,并采血样进行HIV、梅毒和丙肝检测。结果 3轮分别调查490人、443人和708人,共调查1 641人(次)。大多数人参加调查的目的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。3轮艾滋病防治知识知晓率分别为89.4%、83.1%、89.3%。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。自报在最近一年,出现过性病相关症状的比例分别为13.9%、11.1%和10.6%。3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%。结论我省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,但传播艾滋病的隐患很大。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。Objective To identify the levels of AIDS knowledge,behavior and HIV prevalence among men who have sex with men（MSM） in Anhui,China.Methods A convenient sample of MSMs was recruited for 3 times during 2008-2009 with 6 months in between.Participants were interviewed face-to-face using semi-structured questionnaire and a blood sample was collected from each participant for testing for HIV,syphilis and hepatitis C（HCV）.Results A total of 1641 persons（person-time） were surveyed,with 490 in the first round,443 in the second round and 708 in the third round.Most of the participants took part in the surveys for HIV testing,with the proportions of 72.4%,71.8% and 74.7% in the 3 rounds respectively.Most of the participants reported they were gay or bi-sexual man.Many of them sought for sexual partners through Internet.The rates of AIDS knowledge were 89.4%,83.1% and 89.3%（P=11.32,χ^2=0.003） in the 3 rounds.In each of the 3 surveys,more than 10% of them didn＇t use condoms in the past 6 months.Selling and buying sex were common and condom-use rate was low when they sold and bought sex.About 20%～30% reported having sex with women and condom-use rate was low.The proportion of participants reporting having had STD related symptoms in the past year was 13.9%,11.1% and 10.6% respectively.The HIV prevalence was 2.9%,1.6% and 1.4% respectively,and the HCV prevalence was 11.0%,6.8% and 8.8% respectively.Conclusions Among MSM in Anhui,the AIDS knowledge level was high,the HIV prevalence was low,and there were risks for HIV transmission.Comprehensive health education and intervention should be strengthened to reduce risk behaviors,in order to keep the low HIV prevalence in Anhui,China.
