Note. ACA = Affordable Care Act; CI = confidence interval; Coef = coefficient; OR = odds ratio. We used the conceptual framework of Andersen social behavioral model to select the covariates that were associated with health care expenditures. Model 1 = covariates included predisposition factors (i.e., race/ethnicity, gender, marital status, US-born, and interview language); model 2 = model 1 + enabling factors (i.e., education, family income, health care access, urban/rural, and US Census region); model 3 = model 2 + clinical need factors (i.e., self-reported physical and mental health). Full sets of results are omitted for brevity but are available upon request. Multivariate logistic regressions were estimated for any use of physician visit, prescription drug, emergency department visit, and hospital inpatient use. The coefficients of interaction terms of race/ethnicity or age with year indicator were not significant. Results of these regressions are omitted for brevity but are available upon request. All the estimates are nationally representative.
