Multiple studies reported a fast-spreading human immunodeficiency virus (HIV) epidemic among men who have sex with men (MSM) in China. This study aimed to estimate the magnitude and time trends of HIV prevalence among MSM in different geographical regions of China through a systemic review and meta-analysis.
A total of 94 articles were identified (25 in English and 69 in Chinese) and analyzed. National HIV prevalence among Chinese MSM has increased over this period, from 1.4% (95% confidence interval [CI]: 0.8%-2.4%) in 2001 to 5.3% (95% CI: 4.8%-5.8%) in 2009. MSM in Southwest China have the highest HIV prevalence, of 11.4% (95% CI: 9.6%-13.5%) in comparison with other regions, which range 3.5% to 4.8%.
Significant increases in HIV prevalence among MSM were consistently observed across all Chinese regions. There is an urgent need for implementation of effective public health interventions to curb the spread of HIV infection among MSM across China, especially in the Southwest.
多项研究报告称，中国男男性行为者（MSM）中艾滋病毒（HIV）呈快速传播态势。本研究旨在通过系统综述和荟萃分析，估计中国不同地区 MSM 中 HIV 流行的规模和时间趋势。
共确定了 94 篇文章（25 篇英文，69 篇中文）并进行了分析。中国 MSM 中的 HIV 流行率在此期间呈上升趋势，从 2001 年的 1.4%（95%置信区间[CI]：0.8%-2.4%）上升至 2009 年的 5.3%（95%CI：4.8%-5.8%）。与其他地区相比，中国西南部的 MSM 艾滋病毒流行率最高，为 11.4%（95%CI：9.6%-13.5%），其他地区的流行率为 3.5%至 4.8%。
中国所有地区的 MSM 中 HIV 流行率均持续显著上升。迫切需要实施有效的公共卫生干预措施，以遏制中国各地 MSM 中 HIV 感染的传播，特别是在西南部地区。
