目的 了解近年深圳市男同性恋性病和艾滋病感染的发展趋势及行为特征，并对其进行分析，为实施有效的干预策略提供客观依据。方法 从2002～2005年连续4年在深圳市男同性恋活动场所对目标人群进行包括梅毒、疱疹和HIV等病原抗体血标本检测，并于2004年底通过匿名问卷进行行为监测。结果 HIV抗体、梅毒抗体捡出率分别由2002年的0．9％和9．4％上升至2005年的2．7％和15．8％；普遍存在多性伴现象，与艾滋病传播有关的，无保护肛交等危险性行为发生率高；安全套使用率低，或从未使用安全套的比例为40．7％。只有22．7％每次使用安全套；现场被检出和确认为HIV阳性的11例感染者91％合并患有梅毒和疱疹，有过半是提供性服务的年轻人。结论 深圳市同性恋HIV感染率几年来迅速上升，普遍存在多性伴、无保护的肛交等行为，目前未建立使用安全套等保护意识，提示应及尽早实施对男同性恋的有效行为干预，遏制STD／HIV在人群中的迅速传播，并有效阻断其向其他人群传播的危险。
