ObjectiveTo systematically review the infection and colonization of Mycoplasma genitalium (Mg) in the reproductive tract of pregnant females in China. MethodsPubMed, Web of Science, SinoMed, CNKI, VIP and WanFang Data databases were electronically searched to collect cross-sectional studies on Mg infection in pregnant females in China from inception to October 10, 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies; then, meta-analysis was performed by using R1.1.463 software. ResultsA total of 23 cross-sectional studies were included. The results of meta-analysis showed that the prevalence rate of Mg infection in pregnant females was 4.86% (95%CI 2.84% to 7.38%). The prevalence rates of Mg infection in females with ectopic pregnancy, spontaneous abortion, induced abortions and PROM were 13.01% (95%CI 6.90% to 20.69%), 11.81% (95%CI 3.30% to 24.59%), 6.11% (95%CI 2.70% to 10.77%), and 12.63% (95%CI 9.56% to 16.06%), respectively. ConclusionCurrent evidence shows that the prevalence rate of Mg infection in females with ectopic pregnancy, spontaneous abortion and premature rupture of membranes are higher than those in other pregnant females. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
