The impact of diabetes insurance mandates on infant health

Among the factors thought to contribute to lagging improvements in infant health in recent years are increasing obesity and diabetes prevalence among women of childbearing age. This article uses a difference‐in‐difference‐in‐difference empirical strategy to investigate the impact of mandated insurance coverage for diabetes on adverse pregnancy outcomes. Among educated women, who have high rates of coverage through private insurance that is subject to insurance mandates, diabetes mandates are associated with a reduction in low birth weight and premature birth prevalence. These gains are concentrated among older women and are larger for African‐Americans. There is a weaker effect on the prevalence of high birth weight, potentially because of the deleterious effects of an increased probability of pregnancy weight gain in excess of 35 pounds among diabetic women in states with mandates.
