Medicaid family planning expansions and related preventive care.

I examined the impact of state expansions in eligibility for Medicaid family planning services on the utilization of Papanicolaou (Pap) tests, clinical breast examinations, HIV testing, and routine doctor check-ups among women aged 21 to 44 years using the Behavioral Risk Factor Surveillance System (1993-2009). Using a natural experiment approach, I found significant increases in Pap tests and clinical breast examinations among women eligible for services under the expansions but no significant change in HIV testing or routine doctor check-ups.
