目的了解比较柳州市男同性恋或双性恋者性行为学特征,为HIV知识宣传及行为干预提供理论依据。方法于2008-10/12依托同性恋活动场所和志愿者组织通过网络宣传、朋友相互介绍、外展干预宣传等方式招募被调查对象,采用匿名面对面询问方式进行问卷调查,对其中男同性恋和男双性恋者的性行为进行比较分析。结果共调查300人,其中59.0%、39.0%分别自我认同为同性恋或双性恋者。男同性恋与男双性恋者中,20～29岁组分别占52.6%、38.5%;在婚比例分别为17.0%、49.6%(P均<0.01)。同性恋者首次性行为是男性性伴的比例(69.5%)高于双性恋者(28.2%),与男性首次性行为的年龄(25.8岁)低于双性恋者(30.2岁)。最近6个月同性恋者与男性肛交的比例(89.3%)高于双性恋者(88.8%)(P>0.05);且肛交时每次都用安全套的比例均较低,分别为(P>0.05)。最近6个月同性恋、双性恋者与女性发生性行为的比例分别为26.0%、53.8%(P<0.01);且与女性发生性行为时每次都用安全套的比例均很低。结论男双性恋者有较高比例的在婚率和异性性行为,男同性恋者与男性发生性行为的比例更高,且两者的多性伴、无保护性肛交的频率很高,应加强对该人群的监测和综合干预。
