Trichomonas vaginalis infection in Ethiopia: A systematic review and meta-analysis.

BACKGROUND

An estimated 30 million new cases of Trichomonas vaginalis are recorded annually in sub-Saharan Africa. In Ethiopia, there is no study that systematically compiled the burden of T. vaginalis. Therefore, this study aimed to estimate the pooled prevalence of T. vaginalis in Ethiopia.

METHODS

Electronic databases such as PubMed/Medline, EMBASE, Science Direct, Scopus, HINARI, Google Scholar, and Cochrane Library were systematically searched, and studies with high-quality Newcastle Ottawa Scale scores were included. Analyses were performed using STATA version 14 software, and heterogeneity of studies was assessed using the Cochrane's Q test statistics and I2 test statistics. Sub-group, sensitivity analysis, and publication bias were performed.

RESULTS

Ten eligible studies consisting of 2979 study participants were included. The overall pooled prevalence of T. vaginalis infections in Ethiopia was 9.62%. Sub-group analysis showed that the overall pooled prevalence of T. vaginalis infections in pregnant women and other study groups was 6.68% and 12.86%, respectively. Publication bias was detected by funnel plots and Egger's tests.

CONCLUSIONS

This study showed that the overall pooled prevalence of T. vaginalis infections was relatively high. This study should trigger policy makers, governmental and non-governmental organizations, and healthcare providers to give attention for prevention and control of T. vaginalis infection.
