ABSTRACT
The prevalence of HIV among men who have sex with men (MSM) has become a major public health challenge in China. However, our understanding of the nationwide epidemiology is far from complete. We performed a large-scale systematic review and meta-analysis to comprehensively evaluate HIV epidemiology among MSM in China based on studies published up to March 2016. In total, 325 studies met our eligibility criteria. The results showed that the overall national prevalence of HIV among MSM was 6.32% (95% CI: 6.05–6.60%) and that the HIV prevalence dramatically increased over the past 14 years from 1.31% to 11.44%, with the highest HIV prevalence in those aged 50 years and older (19.31%). HIV prevalence was greater in the illiterate population (16.76%) than those who had received an education. MSM who sought partners at bathhouses/saunas had the highest associated prevalence of HIV (14.58%). Additionally, an extraordinarily high HIV prevalence of MSM was found in the southwest compared to other regions. Finally, participants who had never used a condom during the past 6 months had an increased risk of HIV infection. Our analysis provides valuable information for HIV prevention among MSM in China.
