目的了解2012年辽宁省男男性行为人群(MSM)的艾滋病病毒(HIV)感染现状及其高危行为情况,为在该人群中进一步开展干预工作提供参考。方法采取滚雪球的方法,招募2012年居住在辽宁省的MSM进行问卷调查,收集社会人口学特征、艾滋病知识知晓情况和高危行为特征等信息,并抽血检测HIV抗体。使用Epidata3.1建立数据库并进行数据双录入,并使用SPSS 19.0进行数据分析。结果共收回调查问卷2 006份。调查对象中艾滋病知识知晓率为95.8%(1 922人),6.7%(135人)HIV抗体检测阳性。最近一次与同性发生肛交时的安全套使用率为88.4%,与同性发生商业性行为时的安全套使用率为94.1%,1.2%最近一年曾被诊断患过性病。最近一次肛交未使用安全套者,感染HIV的风险是使用者的23.29倍,最近一次与同性发生商业性行为时未使用安全套者,感染HIV的风险是使用者的122.17倍,最近一年未接受过同伴教育者,感染HIV的风险是接受过的45.43倍,居住在大连市的MSM,感染HIV的风险是营口市的2.34倍。结论虽然辽宁省MSM的艾滋病知识知晓率和安全套使用率较高,但是HIV感染率处于较高水平,需重点开展防控工作。
