Intra‐Ethnic Coverage Disparities among Latinos and the Effects of Health Reform
研究分析了九个拉丁裔亚群体在医保覆盖上的差异，发现亚群体间覆盖差距高达30个百分点，且《平价医疗法案》对各亚群体的影响显著不同。
OBJECTIVE: To examine the patterns of insurance coverage among nine Latino subgroups and assess heterogeneous effects of the Affordable Care Act (ACA) among these groups. DATA SOURCES: American Community Survey (2010-2014). STUDY DESIGN: We examined pre-ACA disparities in coverage using linear probability models. Then, we used interrupted time series and triple-difference models to evaluate coverage changes associated with the ACA and Medicaid expansion, respectively. PRINCIPAL FINDINGS: Pre-ACA coverage disparities between Latino subgroups were nearly 30 percentage points-larger than the gap between whites and Latinos as a whole. Coverage changes associated with the ACA and Medicaid expansion differed significantly between subgroups, with the largest gains among South Americans, Central Americans, and Mexicans. CONCLUSIONS: Latino subgroups show marked heterogeneity in baseline coverage rates and responses to the ACA.
