Experimental evidence on the impacts of supplying iron-fortified salt through school lunch on children’s health and cognitive development in India
The prevalence of nutritional anemia (iron deficiency) among school-age children continues to be high and is a major concern for maternal and child health in developing countries, particularly in South Asia. While it is well documented in the efficacy studies that salt fortified with iron and iodine, known as double-fortified salt (DFS), can address iron deficiency among anemic individuals, there remains a significant gap between the efficacy (potential effect) and the effectiveness (actual effect under real-world conditions) of DFS.
We conduct a field experiment on a sample of 2,000 grade II children in Bihar, India. Children in the treated schools consumed iron-fortified school lunches for a year. We collect data on hemoglobin level, cognitive tests, reading and math scores, and school attendance to econometrically test the impacts of DFS intervention on anemia reduction and cognitive development.
