目的分析2016—2019年无锡市男男性行为者HIV感染情况及其影响因素,为制订防治对策和干预措施提供依据。方法采用滚雪球、网络等方法招募对象,由经过专业培训的调查员对其进行面对面问卷调查,并采集血液样本进行艾滋病(HIV)抗体检测。结果共监测男男性行为者1451人,其中HIV知识知晓率为93.52%,HIV检测抗体阳性率5.86%。人口学特征分析显示不同年龄组(χ2=18.81,P<0.05)、不同性取向间(χ2=28.84,P<0.05)差异具有统计学意义;高危行为分析显示最近6个月是否与同性发生过肛交性行为(χ2=12.63,P<0.05)、最近6个月是否与发生同性商业性行为(χ2=10.15,P<0.05)和最近6个月是否与异性发生过性行为(χ2=33.15,P<0.05),差异具有统计学意义。其他情况下HIV抗体检测阳性率差异均无统计学意义(P>0.05)。结论应继续加强男男性行为人群的健康教育和干预措施。
