目的了解男男性行为人群艾滋病相关知识、行为及生物学现状,为开展健康教育和行为干预提供依据。方法通过活动场所和网络招募等方法招募男男性行为者,由经过培训的专业人员逐一进行问卷调查,并采血样作HIV抗体、HCV抗体和梅毒抗体检测。结果调查男男性行为者386名,艾滋病相关知识问题8个,总知晓率为91.65%;最近6个月与同性发生过肛交性行为的比例为78.24%,与异性发生过性行为的比例为14.77%;最近1次与同性肛交安全套使用率为73.59%,与异性发生性行为时安全套使用率为63.17%;使用过毒品的比例为1.30%;最近1年曾被诊断患过性病的比例为2.85%;最近1年接受过艾滋病咨询的比例为75.13%,接受过艾滋病检测的比例为50.26%;本次检测HIV抗体阳性率为10%,梅毒抗体阳性率为18.21%,HCV抗体阳性率为0.28%。结论男男性行为人群艾滋病相关知识知晓率较高,但安全套使用率较低,安全性行为意识不强,是当地艾滋病防治的重点人群,应大力开展以核心同伴宣传员预防干预为主的行为干预活动。
