Background This study was conducted to summarise the HIV epidemic, sexual behaviours and HIV testing among men who have sex with men (MSM) attending university in China.
Five databases were searched for student MSM information in English and Chinese language publications. Meta-analyses were performed to calculate the pooled prevalence of HIV and syphilis, pooled mean age at first anal intercourse (AFAI) and the rate of other HIV-related behaviours among MSM attending university in China. Univariate meta-regression and subgroup analysis were conducted to explore potential sources of heterogeneity. Publication bias was measured using Egger's test.
Thirty-three articles representing 31 studies were included in the analysis. The pooled HIV prevalence was 4.1% (95% CI 3.1-5.0%). The estimated AFAI was 18.7 years, but 37.5% of students had their first anal intercourse before 18 years of age. Most (88.2%) had their first sexual intercourse with a male partner. Of the MSM attending university, 4.2% of MSM engaged in commercial sex (either selling or buying sex), 10.3% had ever engaged in group sex, 13.1% had had sex with a female partner in the past month and 10.1% had ever used drugs. Most (77.7%) sought sex partners via geosocial networking gay apps or the Internet, and 42.9% had ever tested for HIV. There was a tendency for an increase in lifetime HIV testing rate from 32% in 2005-07 to 53% in 2014-16.
This review found high HIV prevalence, early AFAI and a high prevalence of sexual risk behaviours among MSM attending university in China. Interventions aimed at increasing HIV testing and reducing sexual risk behaviours are urgently needed among this young population.
背景 本研究旨在总结中国大学生男男性行为者(MSM)中的艾滋病流行情况、性行为及艾滋病检测情况。
检索五个数据库,查找中英文出版物中有关大学生男男性行为者的信息。进行荟萃分析,以计算中国大学生男男性行为者中艾滋病病毒(HIV)和梅毒的合并患病率、首次肛交的合并平均年龄(AFAI)以及其他与HIV相关行为的发生率。进行单变量荟萃回归和亚组分析,以探索异质性的潜在来源。使用Egger检验评估发表偏倚。
分析纳入了代表31项研究的33篇文章。HIV合并患病率为4.1%(95%置信区间3.1 - 5.0%)。估计首次肛交年龄为18.7岁,但37.5%的学生在18岁之前首次肛交。大多数(88.2%)与男性伴侣首次发生性行为。在大学生男男性行为者中,4.2%的人有商业性行为(卖淫或嫖娼),10.3%的人曾有过群交,13.1%的人在过去一个月内与女性伴侣发生过性行为,10.1%的人曾使用过毒品。大多数(77.7%)通过基于地理位置的社交同性恋应用程序或互联网寻找性伴侣,42.9%的人曾进行过HIV检测。终身HIV检测率有从2005 - 2007年的32%上升到2014 - 2016年的53%的趋势。
本综述发现中国大学生男男性行为者中HIV患病率高、首次肛交年龄早且性风险行为患病率高。迫切需要针对这一年轻人群开展旨在增加HIV检测和减少性风险行为的干预措施。
