Addressing micronutrient deficiencies in Zambia is recognized as a national priority by the government due to its major contribution to morbidity and mortality among children, especially infants in their formative years. One of the most successful, cost-effective, and recommended strategy to address micronutrient malnutrition is 'in-home fortification' with micronutrient powders (Sprinkles being the most widely recognized) along with nutrition education. While this intervention has proven to be safe, effective, and efficacious in numerous other countries, a specific national protocol must be developed to maximize its effect on reducing anaemia in Zambian children. The proposed research aims to inform such protocol.
