Element of survival: Isolating the causal effect of access to iodized salt on child health in India
Despite India’s longstanding efforts to combat Iodine Deficiency Disorders through a Universal Salt Iodization program, only 51% of households were using iodized salt in 2005. In order to justify efforts to actively expand the program, it is crucial to establish a causal link between access to iodized salt and child health. This study examined household salt iodine concentration, anthropometric outcomes, and birth histories of over 18,000 children from the 1998 India National Family Health Survey.
