We combine estimates from the two sets of analyses to construct estimates of the effect of health insurance on use of prenatal care and infant health. We find that the eligibility expansions reduced the proportion of pregnant women who were uninsured by approximately 10 percent, although this decrease in uninsured came with the expense of a substantial reduction in private insurance coverage. Changes in Medicaid eligibility were associated with very small and statistically insignificant changes in prenatal care use, birth weight, and incidence of low-birth weight. ER -
