BackgroundThere are substantial disparities in breast and cervical cancer screening that stem from lack of health insurance. Although the Affordable Care Act (ACA) expands insurance coverage to many Americans, there are differences in availability of Medicaid coverage across states.PurposeTo understand the potential impact of Medicaid expansions on disparities in preventive care for low-income women by assessing pre-ACA breast and cervical cancer screening across states currently expanding and not expanding Medicaid to low-income adults.MethodsData from the 2012 Behavioral Risk Factor Surveillance System (analyzed in 2014) were used to consider differences in demographics among women for whom screening is recommended, including income and race/ethnicity, across expansion and nonexpansion states. Self-reported screening was compared by state expansion status overall, for the uninsured, and for low-income women. Logistic regressions were estimated to assess differences in self-reported screening across expansion and nonexpansion states controlling for demographics.ResultsWomen in states that are not expanding Medicaid had significantly lower odds of receiving recommended mammograms (OR=0.87, 95% CI=0.79, 0.95) or Pap tests (OR=0.87, 95% CI=0.79, 0.95). The difference was larger among the uninsured (OR=0.72, 95% CI=0.56, 0.91 for mammography; OR=0.78, 95% CI=0.65, 0.94 for Pap tests).ConclusionsAs women in nonexpansion states remain uninsured and others gain coverage, existing disparities in cancer screening by race and socioeconomic status are likely to widen. Health risks and associated costs to underserved populations must be taken into account in ongoing debates over expansion.Copyright © 2015 American Journal of Preventive Medicine.
