Data from the 1997 National Survey of America's Families (NSAF) are used to analyze access to care and use of health care services for low-income women. Three groups of women are examined: those with Medicaid coverage, those with private coverage, and those with no insurance. Findings show that uninsured women faced larger access barriers and utilized fewer services, particularly preventive care services, than women with either public or private coverage. Access and use did not differ greatly between Medicaid and privately covered women. The results suggest that expansions in coverage, either through Medicaid or through private options, could improve access to care for uninsured women.
