目的了解芜湖市男男性行为者(MSM)艾滋病相关知识知晓率、性行为学特征及其影响因素,为开展有效干预措施提供依据。方法采用分类滚雪球的抽样方法对MSM进行匿名问卷调查。结果共对434名男同性恋者进行了调查,艾滋病相关知识知晓率为80.4%。经Logistic回归分析发现,寻找性伴的场所档次和文化程度越高,其知晓率越高,年龄越高知晓率越低。最近6个月所有MSM均与同性发生过性行为,36.9%与同性发生性行为时每次都使用安全套。最近6个月,10.8%的调查对象与同性发生过商业性性行为,25.1%的调查对象与异性发生过性行为。样本来源、艾滋病知识知晓率、是否进行过性病诊疗和最近1年是否做过AIDS检测对最近6个月MSM性行为时每次都用安全套有影响。结论在MSM中存在知识与行为脱离现象,应针对不同年龄组的MSM采取不同的干预措施。
