Optimizing child nutrition in resource-limited settings: Sustainable community-based interventions and global lessons

Optimal child nutrition is fundamental to physical growth, cognitive development, immune function, and long-term health outcomes. However, millions of children in resource-limited settings are still affected by malnutrition in its many forms, including undernutrition, micronutrient deficiencies, and increasing rates of childhood obesity. This review article examines the burden and determinants of malnutrition in low-resource settings, analyzes successful community-based interventions, highlights global case studies, and proposes a roadmap for sustainable and scalable nutrition improvement. Based on a comprehensive synthesis of global research and public health initiatives, this review is intended to inform healthcare professionals, community leaders, NGOs, and policy makers engaged in pediatric and maternal-child health.
