A global meta-analysis of gonorrhoea and chlamydia prevalence among men who have sex with men from 2000 to 2022.

IntroductionWe conducted a global systematic review and meta-analysis of gonorrhoea and chlamydia among men who have sex with men (MSM) from 2000 to 2022.MethodsWe searched four databases to identify studies conducted between 1 January 2000 and 19 April 2022 that reported prevalence from aetiological assays. We extracted data, calculated point estimates, corrected and then pooled them using random-effects models. We stratified results by United Nations regions and conducted subgroup analyses established Results172 studies met our inclusion criteria, providing 387 prevalence data points from 57 countries. The overall pooled prevalence for gonorrhoea was 7.2% [95% CI: 6.0 to 8.5; 188 data points; = 347,253] and for chlamydia was 9.9% (95% CI: 8.8 to 11.0; 190 data points; = 342,799). For gonorrhoea, pooled prevalence between 2000 and 2010 was 5.0% (95% CI: 3.7 to 6.5; 89 data points; = 78,557) compared to 9.3% (7.7-11.1; 99 data points; = 268,696) between 2011 and 2022, < 0.001. For chlamydia, pooled prevalence between 2000 to 2010 was 6.6% (95% CI: 5.4 to 7.9; 95 data points; = 91,015) compared to 13.6% (12.0-15.2; 95 data points; = 251,784) between 2011 and 2022, < 0.001.ConclusionA holistic approach is needed to reduce the curable STIs burden among MSM.
