Abstract
PURPOSE: Previous work has demonstrated the Affordable Care Act (ACA) increased young adults' health care access during its first years. However, it is unclear if these trends continued through 2017; recent policies enacted by the Trump administration may have decreased the ACA's effectiveness. Our purpose was to determine changes in young adults' health care access during the transition from Obama to Trump administrations. METHODS: Data on noninstitutionalized U.S. young adults (18-24 years) was obtained from the Behavioral Risk Factor Surveillance System 2011-2017 (N = 173,848). We used interrupted time series and difference-in-differences analysis to quantify changes in self-reported insurance coverage, access to a primary care physician, and unmet care because of cost from 2013 to 2017. RESULTS: Young adults' health care access continued to improve through 2016; for instance, the percentage of respondents experiencing uninsurance declined by 8.7 points from 2013 to 2016 (95% confidence interval [CI] -9.4 to -8.0). However, these trends began to reverse and from 2016 to 2017, the percentage of young adults who experienced uninsurance increased by 1.4 points (95% CI .6-2.1), not having a personal doctor increased by 1.1 points (95% CI .2-2.0), and unmet care because of cost increased by 1.0 points (95% CI .3-1.7). The 2017 declines in access were concentrated in states which did not expand Medicaid and in households earning above 138% of federal poverty level. CONCLUSIONS: Health care access declined for young adults in 2017, after several years of improvements. These changes correspond with recent policy actions, which may have weakened the ACA's reforms.
