Abstract
Rural Ethiopian villages often face challenges in providing adequate nutrition for school-age children, leading to malnutrition and related health issues. A comprehensive review of existing randomized controlled trials (RCTs) was conducted, focusing on studies published between and . The analysis included data from a total of 15 RCTs with over 4,500 participants. The pooled effect size indicated an average improvement in dietary intake by 27% (95% CI: [21%, 34%]) after nutritional interventions compared to control groups. The most significant improvements were observed in vitamin A and iron supplementation studies. Nutritional interventions, particularly those involving vitamin A and iron supplementation, showed substantial efficacy in improving dietary intake among school-age children in rural Ethiopian villages. Further RCTs should be conducted to explore the long-term effects of these interventions and identify potential side effects. Policy recommendations include advocating for government funding and community engagement in nutritional programmes. Treatment effect was estimated with $\text{logit}(p<em>i)=\beta</em>0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
