Systematic review finds nutritional interventions improve maternal health outcomes in pregnant women, suggesting the need for policy change.
Nutritional deficiencies during pregnancy are prevalent in northern Nigerian townships, leading to adverse health outcomes for both mothers and infants. A comprehensive search strategy was employed using multiple databases to identify relevant studies. Studies were assessed based on predefined inclusion criteria, including language and publication type. Nutritional supplementation significantly improved maternal health outcomes such as anemia reduction by a mean of $0.5$ standard deviation (SD) within the first trimester. The systematic review highlighted the effectiveness of nutritional interventions in improving maternal health, though heterogeneity across studies limited generalizability. Further randomized controlled trials are recommended to validate findings and inform policy development for nutrition support during pregnancy.
