Abstract
Bangladesh have made a remarkable change of nutritional status of children over the decade despite of poverty. Stunting, underweight and wasting in children under age five years were gradually reduced from 1990s to 2020s and improved children health status over the year. This paper explains the trends of nutritional status of children in Bangladesh over the decades by different age groups of children, causes of changing nutrition status, and future challenges for development in Bangladesh. The national level survey (BDHS), national plan and policy paper, and existing literature are used for the study. Changing nutritional status of children aged under five years from high level stunting, underweight and wasting to gradual improved is remarkable for Bangladesh. Aged between 12-23 months children are more vulnerable for being stunt, waste and underweight than other ages. There have a rural-urban, wealth status and mother’s education affect the nutritional status of children. Income and poverty reduction, improve water and sanitation, maternal and child health, food and dietary practice and many policies and programs are the main causes for changing nutrition level of children in Bangladesh. But there are many challenges for future development for children nutrition status in Bangladesh like child and under five mortality, child malnutrition, double burden of malnutrition, and gaps of policies and programs in Bangladesh to achieve national plan, SDGs target and achieving demographic dividend with healthy population.
