Antenatal Care Reduces Neonatal Mortality in Ethiopia: A Systematic Review and Meta-Analysis of Observational Studies

BackgroundNeonatal deaths remain a serious public health concern in Ethiopia; being one of the top five countries contributing to half of the neonatal deaths worldwide. Although antenatal care (ANC) is assumed as one of the viable options that contribute to neonatal survival, findings from original studies indicated disparities in the effect of ANC on neonatal mortality. Thus, this review aimed to determine the pooled effect of ANC on neonatal mortality in Ethiopia.MethodsDatabases such as PubMed, EMBASE, CINAHL, HINARI, and Cochrane Central Library were searched for articles using keywords. Selection of eligible articles and data extraction were conducted by an independent author. The risk of a bias assessment tool for non-randomized studies was used to assess the quality of the articles. Comprehensive meta-analysis version 2 software was used for meta-analysis. Heterogeneity and publication bias of included studies were assessed using I2 test statistic and Egger test, respectively. The random-effect model was employed; an outcome is reported using a risk ratio with a 95% confidence interval.ResultsOf 28 included studies, 20 showed receiving at least one ANC visit had a significant association with neonatal mortality. Accordingly, the estimated pooled risk ratio for neonatal mortality was 0.59 (95% CI 0.45, 0.77) among infants born to women who had at least one ANC visit compared to infants born to women who had no ANC visits.ConclusionThis finding indicated that neonatal mortality was decreased among infants born to women who had at least one ANC visit compared to infants born to women who had no ANC visit. Therefore, promoting and strengthening ANC service utilization during pregnancy would accelerate the reduction of neonatal mortality in Ethiopia. In some studies, providing ANC services reduces the risk of neonatal mortality, in others, the ANC visits did not significantly decrease neonatal mortality in Ethiopia, which represents a dismal picture of neonatal mortality (NM) in sub-Saharan Africa (SSA) region. Therefore, evidence emanated from comprehensive searches of review performed with several studies represented from various regions of the country which determine the effect of ANC on NM is essential to reinforce strategies that could help for newborn survival and wellbeing of neonates in Ethiopia. Hence, this study aimed to systematically examine the effect of ANC on NM by combining a wide range of reviews, to provide concrete evidence for policymakers.
