[Seroprevalence of Toxoplasmosis among Pregnant Women in Benin: Meta-Analysis and Meta-Regression].

To assess the seroprevalence of toxoplasmosis among pregnant women in Benin, we conducted a meta-analysis using the PRISMA criteria. Al research published between 1990 and 2018 on toxoplasmosis among pregnant women Benin were eligible. A total of five databases were investigated, and the extracted data were subjected to a meta-analysis under R 3.1 using both random effect model and fixed effect model. The overall prevalence of toxoplasma-specific IgG among pregnant women was 47% (CI 95%: 40-53) and that of specific IgM was 2% (CI 95%: 1-3). The infection rate in urban areas (52%) was significantly higher than in rural areas (33%). The two main risk factors identified by the various eligible studies were the age of the pregnant women and the consumption of raw vegetables. We show that toxoplasmosis is endemic in pregnant women in Benin, implying that primary prevention measures must be put in place by the competent authorities to control this infection.
