摘要
目的 评价中国青年男男性行为人群（YMSM）艾滋病相关行为与感染状况。方法 检索中国知网、万方数据和PubMed，检索时限为2005年1月至2016年2月，2名评价员按照纳入与排除标准独立对文献进行筛选、提取和评价，采用R软件进行Meta分析。结果 共纳入文献37篇，样本含量32 110人。75.5%（95%CI：68.8%～81.2%）YMSM以互联网为结识性伴主要场所，多性伴行为发生率为65.5%（95%CI：60.0%～70.6%）。近6个月89.1%（95%CI：84.2%～92.6%）YMSM存在肛交性行为，安全套坚持使用率为42.0%（95%CI：37.4%～46.6%）；11.4%（95%CI：8.4%～15.4%）YMSM存在阴道性行为，安全套坚持使用率为36.9%（95%CI：32.4%～41.6%）。YMSM艾滋病感染率为5.0%（95%CI：3.9%～6.5%），亚组分析显示，YMSM艾滋病感染率呈逐年递增趋势，且西部地区YMSM艾滋病合并感染率（6.3%，95%CI：4.7%～8.5%）显著高于东（4.2%，95%CI：2.6%～6.6%）、中部（1.9%，95%CI：0.8%～4.6%）地区（P〈0.05）。结论 YMSM普遍存在多性伴与无保护性行为，艾滋病流行形势严峻，亟待针对该人群开展艾滋病干预工作。
Objective To assess the prevalence of AIDS-related sexual behaviors and HIV infection status in young men who have sex with men （YMSM） in China. Methods Literature retrieval was conducted to obtain the related literature indexed by CNKI, Wangfang and PubMed databases from January 2005 to February 2015. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted data and assessed the methodological quality. Meta-analysis was performed by the R software. Results Thirty seven studies involving 32 110 YMSM were included. 75.5%（95%CI：68.8%-81.2%） YMSM sought sexual partners through Internet and 65.5% （95%CI：60.0%-70.6%） had more than 2 sexual partners. In the last 6 months, 89.1% （95%CI：84.2%-92.6%） YMSM had anal intercourse and 42.0% （95%CI：37.4%-46.6%） used condom consistently; 11.4% （95%CI：8.4%-15.4%） had vaginal intercourse and 36.9% （95%CI：32.4%-41.6%） used condom consistently. The pooled prevalence of HIV infection was 5.0% （95%CI：3.9%-6.5%）, sub-group analysis showed that the prevalence of HIV infection in the eastern, central and western China were 4.2% （95%CI：2.6%-6.6%）, 1.9% （95%CI：0.8%-4.6%）, 6.3% （95%CI：4.7%-8.5%）, respectively, and there were significant differences among different areas. Conclusion The prevalence of AIDS-related risk sexual behaviors and incidence of HIV infection in YMSM were high in China, it is necessary to conduct AIDS intervention in this population.
