| dc.description.abstract | Background:
Schistosomiasis is a highly prevalent parasitic disease that can lead to adverse maternal and perina tal outcomes. To our knowledge, there has been no systematic review and meta-analysis of schistosomiasis during pregnancy.
Methods:
We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Relevant published studies were searched in international databases (PubMed, Science Direct, Scopus, Web of Science, and Google Scholar), from their inception until May 31, 2020. The retrieved studies were assessed for quality using the Modifed Newcastle-Ottawa Scale. OpenMeta Analyst software was used for the statistical analysis.
Results:
Thirty-two studies enrolling 21024 pregnant women were included in this meta-analysis. All 32 of these studies were conducted in Africa. Of these studies, 19, 11, and 2 investigated S. mansoni, S. haematobium, and com bined S. mansoni and S. haematobium infections, respectively. The pooled prevalence estimate of schistosomiasis during pregnancy was 13.2% (95 CI 11.0–15.4). A random model was used because of high heterogeneity (Q = 99.14; P < 0.001). In subgroup analyses, the pooled prevalence estimate of S. haematobium was signifcantly higher than the pooled prevalence estimates of S. mansoni [22.5% (95% CI 1.6–43.5) vs 8.7% (95% CI 6.0–11.3, P = 0.016), respectively]. The results of meta-regression analyses showed a non-signifcant diference in the prevalence of schistosomiasis during pregnancy according to the study sample sizes and year of publication. Only six studies evaluated the associa tion between schistosomiasis during pregnancy and anemia. Schistosomiasis was associated with anemia in these six studies (OR = 3.02, 95% = 1.25‒7.28, P = 0.014).
Conclusion:
The present meta-analysis suggests that schistosomiasis during pregnancy is an existing health problem. This meta-analysis also highlights the lack of data on the determinants and outcomes of schistosomia sis during pregnancy. Preventive measures are needed and could be part of antenatal care in areas endemic with schistosomiasis. | en_US |
