Nutrition interventions are crucial for child growth in resource-limited settings such as those found in Cameroon. A mixed-methods approach combining quantitative data from anthropometric measurements and qualitative insights from interviews with caregivers was employed to assess programme effectiveness. Somali children who participated in the feeding programmes showed a statistically significant increase in weight-for-age z-scores (WAZ) by an average of 0.2 standard deviations, indicating improved growth outcomes compared to control groups. The intervention programmes demonstrated positive effects on Somali children's nutritional status and health indicators. Future research should focus on sustainability strategies for these programmes and explore the long-term impact on educational attainment. nutrition intervention, feeding programme, growth outcomes, Somali children, Cameroon Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
