Waste and raw-cooked conversion factors were applied to obtain a net weight of each food item registered in the recall surveysFood items were classified into ten food groups, based on those identified in the Minimum Dietary Diversity for Women guide,Urine samples were analysed using the ion-selective electrode method to determine the mEq of Na/l of urine in 24 h
