Task: Question Answering
Input (English): Context: The Affordable Care Act (ACA) Medicaid expansion varies in availability across states.', 'We compared characteristics of low-income uninsured residents in both Medicaid nonexpanding and expanding states with respect to their dietary quality, health risk factors, and access to care.', 'Data from the 2007-2012 National Health and Nutrition Examination Survey was matched with the Kaiser Family Foundation Medicaid expansion data. Bivariate and multivariate regressions were estimated to assess differences across expanding and non-expanding states.', 'The non-expansion group had a lower Healthy Eating Index score (41.8 vs. 44.1, p-value=0.006), a higher Body Mass Index (29.9 vs. 28.9, p-value=0.032), higher obesity prevalence (41% vs. 33%, p-value=0.007), and lower asthma prevalence (14.8% vs. 19.7%, p-value=0.037) compared with the expansion group.\Question: States diet quality , risk factors and access to care among low-income uninsured American adults in states expanding Medicaid vs. expanding under the affordable care act?
Output (English): Differences across states in Medicaid coverage under the ACA may lead to widening disparities in health outcomes between expanding and non-expanding states.
