Millions of people worldwide are affected by iron deficiency anemia (IDA). IDA is a widespread serious public health problem, especially for infants in developing countries mainly because of inadequate intake of iron due to the poor bioavailability of dietary iron in predominately cereal based diets. One of the ways to combat iron deficiency anemia is by supplementation to targeted populations. Although iron drops have been used, they have been largely unsuccessful in reducing the prevalence of anemia because of compliance, distribution and supply issues. Sprinkles® are a new approach to iron delivery that is as efficacious as iron drops and more acceptable. For Sprinkles® to be implemented into nation-wide programs as a sustainable alternative to current iron supplementation approaches, an optimal model of use and distribution for Sprinkles® needs to be established. By comparing daily versus flexible use of Sprinkles® (60 sachets over 60, 90 and 120 days) among infants and young children aged 6-24 months, the primary objectives are to study the effect of the three administration models of Sprinkles® on changes in:
