The effect of nutrition education and counseling on the nutritional status of pregnant women in Ethiopia, 2025: a systematic review and meta-analysis

Abstract

OBJECTIVES: This systematic review and meta-analysis aimed to evaluate the effect of nutrition education and counseling on the nutritional status of pregnant women in Ethiopia, to guide future public health efforts. STUDY DESIGN: Systematic review and meta-analysis. METHOD: test, funnel plot, and Egger's test were performed. A weighted mean difference was used to measure the outcome. RESULT: Nine studies were included in the analysis. nutritional interventions significantly improved mid-upper arm circumference in the intervention group compared to the control group (mean difference = 0.75, 95% confidence interval: 0.37, 1.13). Community-based interventions showed greater effectiveness (mean difference = 1.03, 95% CI 0.66, 1.41), and interventions lasting 6 months or more were more impactful (mean difference = 0.75, 95% CI 0.37, 1.13). Medium-intensity counseling also yielded better results than high-intensity counseling (mean difference = 0.76, 95% CI 0.28, 1.24). Individual-based interventions had a larger effect (mean difference = 0.98, 95% CI 0.17-1.78) compared to group-based ones (mean difference = 0.64, 95% CI 0.20-1.08). Theory-based counseling significantly improved mid-upper arm circumference (mean difference = 0.99, 95% CI 0.58, 1.40). CONCLUSION: Nutrition education has a significant positive impact on the nutritional status of pregnant women, with the most effective results observed in community-based settings, extended interventions, medium-intensity counseling, individualized approaches, and theory-driven frameworks.
