Transitions in insurance coverage from before pregnancy through delivery in nine states, 1996-1999

Efforts to extend coverage to pregnant women, along with an expanding economy, did not prevent increases in the uninsured in the latter 1990s. Welfare reform may have led to declining Medicaid enrollments and caseloads. Data representative of live births in nine states show that in some states more than one-third of all pregnant women and almost two-thirds of low-income pregnant women lacked insurance before their pregnancy in 1996 and 1999. More than one-third of all pregnant women made some change in coverage by the time they delivered their baby. Among low-income women, the largest change was from uninsured status before pregnancy to Medicaid at delivery.
