目的了解杭州市男性同性恋者的性行为及对艾滋病知识的知晓率。方法2003年5月至2004年1月,采用自行设计的调查问卷,对927名男性同性恋者进行匿名式问卷调查。结果被调查者平均年龄为(298±99)岁。1年内平均同性性伴侣数为(734±561)人,其中具有1个同性性伴侣者为199人(2146%),具有2～5个同性性伴侣者为165人(1779%),超过5个以上同性性伴侣者为563人(6073%);179人(1930%)有异性性伴侣,其平均异性性伴侣人数为(112±02)人。其性行为方式中,378人(4066%)有肛交行为,584人(6299%)有口交行为,687人(7411%)有相互手淫行为;34人(366%)有口肛门接触;在179名有异性性伴侣者中,有阴道性交者为107人(5977%),有肛交行为者为66人(3687%),有相互口交者72人(3687%),相互手淫者为47人(2625%)。这部分人群艾滋病知识的正确知晓率比较高,但采取高危险性行为的比例却非常高。只有1111%的男性同性恋者在每次肛交时使用安全套,而绝大多数男性同性恋者在与同性发生性行为时偶尔或根本不采取安全措施,而在与异性发生性行为时,几乎不使用安全套。结论男性同性恋是艾滋病传播的高危人群,应该采取适宜且实用的措施进行干预。
