This systematic review aimed to estimate the prevalence of gonorrhea among two high-risk populations in China and explore the epidemiological features. The review included 49 studies with a total of 88 data points, involving 30,853 female sex workers (FSWs) and 5,523 men who have sex with men (MSM). The pooled prevalence of gonorrhea among FSWs and MSM were 6.9% and 2.5% respectively. The prevalence of gonorrhea showed a decreasing trend among FSWs, but no significant change was observed among MSM in China.
Objectives: This systematic review was conducted to estimate the respective prevalence of gonorrhea among two high-risk populations in China and determine the epidemiological features of gonorrhea in them. Study design: Systematic review. Methods: PubMed, Web of Science, China National Knowledge Infrastructure, and Wanfang databases were searched to identify studies published between January 1, 1990, and October 31, 2022, with gonorrhea prevalence tested by polymerase chain reaction among female sex workers (FSWs) and men who have sex with men (MSM). Meta-regression and subgroup analyses were used to investigate potential factors of heterogeneity across studies. Trend analysis of prevalence was conducted by the Jonckheere-Terpstra method. Results: We identified 88 prevalence data points from 49 studies in China, with 30,853 participants of FSWs and 5523 participants of MSM. Pooled prevalence of gonorrhea among FSWs and MSM were 6.9% (95% confidence interval: 4.6-9.7%) and 2.5% (95% confidence interval: 1.5-3.7%), respectively. The subgroup analyses showed there were period, regional, and specimen collection methods diversities among FSWs, and diversities of the regions and specimen collection anatomical sites were found among MSM, in which the prevalence of rectum and pharynx was significantly higher than the urethra. A decreasing trend in the prevalence of gonorrhea was seen among FSWs (z = -4.03) from 1999 to 2021, not found for MSM in China. (c) 2023 The Authors.
