This study examines the impact of school-based nutrition programmes in Kampala slums, focusing on at-risk children. An ethnographic study was conducted over two years, involving participant observation, interviews with stakeholders, and documentary analysis. Data collection focused on nutrition education initiatives, meal provision systems, and community feedback mechanisms. A significant proportion (45%) of participating children showed improved nutritional status after the programme implementation, attributed to increased access to nutritious meals and enhanced dietary knowledge among caregivers. The study concludes that school-based nutrition programmes have a positive impact on improving nutritional outcomes in slum communities, though challenges persist regarding sustainability and resource allocation. To further enhance effectiveness, the programme should be integrated with broader community health initiatives, including parental education and regular monitoring of child development indicators.
