TABLE 3—

Impact of ACA’s Dependent Coverage Extension on Young Adults’ Health Insurance Coverage and Avoided Health Care Services Because of Cost Issues, by Race/Ethnicity: United States, 2007–2009 to 2011–2013

Race/ethnicity	Change in Health Insurance Coverage, Percentage Point Change (SE)	Change in Avoiding Health Care Services Because of Cost, Percentage Point Change (SE)
Non-Hispanic White	7.05*** (0.30)	‒3.21*** (0.28)
Non-Hispanic Black	1.18* (0.61)	‒0.08 (0.58)
Hispanic	6.09*** (0.52)	‒1.72*** (0.48)
Asian	4.61*** (0.92)	‒2.59*** (0.81)
Hawaiian/Pacific Islander	5.08*** (1.21)	‒3.33*** (1.07)
American Indian/Alaska Native	8.43*** (0.13)	‒2.44* (1.13)
Other non-Hispanic	4.09* (1.85)	0.28 (1.86)
Multiple race, non-Hispanic	4.74*** (0.92)	‒3.06*** (0.90)

Note. ACA = Affordable Care Act. We survey-weighted estimates and adjusted SEs for a complex survey design of the Behavioral Risk Factor Surveillance System Annual Surveys. We included all covariates. Results are from an augmented model that included additional triple interaction terms of the policy group indicator, post-ACA period indicator, and race/ethnicity category (Table A, available as a supplement to the online version of this article at http://www.ajph.org). We computed the marginal effect presented for each racial/ethnic subpopulation as the linear combination of coefficients for the reference group plus the interaction term coefficient for that racial/ethnic category. Table A shows a significant P value for the interaction term for each racial/ethnic group. We conducted Wald tests for the joint significance of all interaction terms: F = 2394.74; P < .001 for change in health insurance coverage; F = 1322.25; P < .001 for change in avoid health care services because of cost.
