Antenatal nutrition programmes are crucial for improving maternal and child health outcomes in resource-limited settings such as Northern Ethiopia. A systematic review and meta-analysis were conducted using data from randomized controlled trials (RCTs) published between and . Studies included those assessing outcomes such as maternal weight gain, blood hemoglobin levels, and birth outcomes. The pooled analysis indicated a significant increase in mean maternal weight gain of 7.8 kg (95% CI: 6.4-9.2) among participants receiving the intervention compared to controls. This meta-analysis supports the efficacy of an antenatal nutrition programme in improving maternal health outcomes, particularly regarding increased weight gain during pregnancy. Future research should focus on long-term follow-up studies and explore cost-effectiveness analyses to inform policy decisions. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
