目的了解鞍山市男男性行为者(MSM)的人类免疫缺陷病毒(HIV)感染情况及其影响因素,为开展有针对性的监测和干预工作提供依据。方法对鞍山市2012—2014年MSM艾滋病哨点的监测数据进行统计分析。结果 1 208例MSM调查对象,HIV阳性率为6.71%,梅毒阳性率6.71%,丙型肝炎(丙肝)阳性率0.99%;艾滋病知识知晓率为92.80%。最近6个月,82.78%的调查对象发生过肛交性行为,最近1次肛交性行安全套使用率为88.80%,安全套坚持使用率为65.70%;近1年中,93.87%的MSM接受过安全套宣传和发放/艾滋病咨询与检测或同伴教育服务;单因素分析结果 ,是否接受过艾滋病预防服务和安全套使用情况是该人群HIV感染的主要影响因素(P<0.05);logistic多因素分析显示,接受过艾滋病预防服务的MSM人群的HIV感染率较低(OR=0.402,P<0.05),梅毒抗体检测结果呈阳性的MSM人群感染HIV的风险较高(OR=0.655,P<0.05)。结论 MSM的HIV感染率达到了较高水平,危险因素广泛存在,建议深入开展艾滋病宣传、安全套推广以及规范性病诊疗等综合干预工作,控制HIV的传播。
