Researchers used a special test to see if pregnant and breastfeeding women knew more about nutrition when they got special care during pregnancy. They also wanted to know if encouraging families to spend money on good food, without giving them food directly, could help make sure they had enough to eat at home. The "Alive & Thrive" plan combined different ways to improve nutrition during pregnancy and childbirth in Bangladesh. They used talks with health workers, videos, and other things to help families eat better. The program used talking and getting the community involved, including men, to help pregnant women eat better. This made families more likely to have enough food and husbands felt better about buying food. The group getting this special care had less trouble getting enough food, better diets, and healthier babies compared to the regular care group.
