This report summarizes the findings of the Rang-Din Nutrition Study evaluation of participant adherence among pregnant and lactating women. Researchers evaluated several aspects of a program to distribute supplements to pregnant and lactating women. They assessed adherence to iron-folic aid and the formulation of lipid-based nutrient supplements being distributed at the time of the interview to determine whether the type of supplement affects adherence and whether adherence to lipid-based nutrients is sustained through 6 months postpartum.
