The Affordable Care Act (ACA) reformed and expanded healthcare coverage with an exchange-based health insurance program. While millions of Americans have benefited from enrollment in ACA marketplace insurance plans, many individuals are likely to be affected by potential future policy changes. Since few studies on the features of marketplace enrollees exist, we adopted a retrospective, cross-sectional study design using 2016 National Health Interview data to identify sociodemographic and health characteristics of enrollees, comparing them to those without insurance. Chi-square tests and logistic regression examined factors associated with enrollees. Adults with multiple chronic diseases (AOR = 1.90, 95% CI = 1.44, 2.50), a history of smoking (AOR = 2.44, 95% CI = 1.82, 3.26), females, married, age 50–64 years, higher educational attainment, and retirees (AOR = 1.86, 95% CI = 1.06, 3.27) were more likely to be enrollees. Since enrollees are largely higher risk individuals with greater healthcare needs, policies that modify the ACA should take these factors into account to reduce potential adverse impacts on enrollees.
