The Rang-Din Nutrition Study was designed to evaluate the effectiveness, within a community-based program, of home fortification approaches for the prevention of maternal and child undernutrition during the first 1,000 days. This report describes results of a follow-up assessment of the study participants when the children were 40 to 52 months of age (i.e., 16–28 months after the interventions ended). It includes indicators of child growth and body composition, cognitive development, and food preferences, as well as information on maternal height and body composition, blood pressure, and hemoglobin.
