目的：收集和分析已发表和未发表的关于成年男性同性性活动流行率的监测和研究数据（包括男变女跨性别者和性工作者）。方法：关键指标已投入运作（曾经和一个男人做爱，去年和一个男人做爱，高风险性行为（定义为无保护的肛交或商业性行为）），并设计了一个数据库来收集数据。进行了调查（PubMed，数据库（美国人口普查局，世界银行，会议）），区域信息提供者提供了帮助。参考报告被用来评估每个记录的方法和信息质量。最好的数据，每个区域的确定和指标估计被用来提出区域范围estimates.Results：男性性行为和/或男男性接触者的人口特征的561项研究中，67解决男性之间的性行为的流行率，不同的数字，每个区域和虚拟不可用在撒哈拉以南非洲，中东/北非，和讲英语的加勒比地区。总体而言，东亚与男子发生性行为的终生流行率（男性）为3-5%，南亚和东南亚为6-12%，东欧为6-15%，拉丁美洲为6-20%。去年的数据大约是终生数据的一半，去年在所有地区的MSM中高危性行为的流行率大约是40-60%，除了南亚，那里是70-90%.Conclusions：关于男性同性性行为的流行率的数据在各地区是稀缺的（在某些地区不存在），有效性和可比性的问题。在南亚和东南亚、东欧和拉丁美洲，估计终生患病率为6-20%，东亚的数字较小。需要对术语和做法进行跨文化分析，并继续对各区域社会中的男-男性行为进行流行病学和社会分析。
Objectives: To collect and analyse published and unpublished surveillance and research data on the prevalence of same sex sexual activity among male adults (including male-to-female transgenders and sex workers) in low and middle income countries.Methods: Key indicators were operationalised (ever sex with a man, sex with a man last year, high risk sex last year (as defined by unprotected anal sex or commercial sex)) and a database was designed for data collection. Searches were conducted (PubMed, databases (US Census Bureau, World Bank, conferences)) and regional informants helped. Reference reports were used to assess the methodology and quality of information in each record. The best data available per region were identified and indicator estimates were used to propose regional range estimates.Results: Of 561 studies on male sexual behaviour and/or MSM population characteristics, 67 addressed prevalence of sex between men, with diverse numbers per region and virtual unavailability in sub-Saharan Africa, Middle East/North Africa, and the English speaking Caribbean. Overall, data on lifetime prevalence of sex with men (among males) yielded figures of 3-5% for East Asia, 6-12% for South and South East Asia, 6-15% for Eastern Europe, and 6-20% for Latin America. Last year figures were approximately half of lifetime figures, and prevalence of high risk sex among MSM last year was approximately 40-60% in all regions except South Asia, where it is 70-90%.Conclusions: Data available on the prevalence of male same sex sexual activity across regions are scarce (non-existent in some areas), with validity and comparability problems. In South and South East Asia, Eastern Europe, and Latin America, a lifetime prevalence of 6-20% was estimated, with smaller figures in East Asia. A cross cultural analysis of terminology and practices is needed, as is continued work on epidemiological and social analysis of male-male sexual practices in societies across regions.
