Nigerian communities face significant challenges in achieving optimal nutrition and health outcomes, with schools serving as potential platforms for intervention. The study employed a mixed-methods approach involving quantitative surveys and qualitative interviews to assess programme effectiveness across multiple schools in diverse regions of Nigeria. Data from 50% of the surveyed schools indicated an increase in vitamin A supplementation rates by 20%, leading to improved vision health among children. School-based health programmes have shown promise in enhancing nutritional and health outcomes, though further research is needed to identify best practices for sustainability. Future interventions should prioritise community engagement and long-term programme scalability to ensure sustained positive impacts on child health.
