【摘要】 目的了解河北省男男性行为者(MSM)的人口学特征、艾滋病相关高危行为、艾滋病病毒(HIV)感染情况及其影响因素,为探索针对性的干预工作模式提供依据。方法 2010-2014年,每年4-6月招募2 000名调查对象,由经过培训的工作人员进行问卷调查,收集调查对象的人口学特征、高危行为发生情况,采集血样进行HIV、梅毒和丙型肝炎病毒(HCV)抗体检测。结果 2010-2014年,共监测MSM 10 000人,HIV抗体阳性率为5.21%(521例),梅毒阳性率5.80%(580例),HCV阳性率0.33%(33例)。最近6个月与同性发生肛交的比例分别为75.0%、87.2%、90.0%、87.7%、87.6%,发生肛交时一直使用安全套的比例分别为57.8%、49.3%、38.4%、50.6%、42.0%,艾滋病知识知晓率在90%左右。梅毒阳性、高年龄组、已婚是HIV感染的危险因素,高文化程度、高知晓率、有异性性行为、接受过同伴教育是HIV感染的保护性因素。结论 MSM中各种高危行为仍然存在,应加强对MSM的行为干预,制定针对性的干预措施。更多还原
