Racial and Ethnic Disparities in Health Insurance Coverage in the USA: Findings from the 2018 National Health Interview Survey

Under the broad context of health care reforms, I explored racial and ethnic disparities in health insurance coverage as well as potential mechanisms that might contribute to these disparities for an extensive list of groups. The study used the 2018 National Health Interview Survey to analyze the effects of race/ethnicity on uninsurance, with adjustment for other predisposing characteristics (age, gender, marital status, and immigration status), enabling resources (education, income, language proficiency, and region), and need (self-reported health status). Results from the study documented an average uninsured rate of 13%, with substantial variations across different racial and ethnic groups, ranging from over 30% among Native Americans and Mexicans to less than 10% among whites and Asian subgroups. Enabling resources significantly reduced uninsurance among African Americans, Puerto Ricans, and Cubans compared to whites. On the other hand, these confounding factors only partially contributed to uninsurance among Native Americans, Mexicans, Mexican Americans, Dominicans, and other Central and South Americans. This study revealed substantial racial/ethnic disparities in uninsured rates, with Native Americans and a few Hispanic subgroups (Mexicans, Mexican Americans, and Dominicans) having higher and Asian Indians having lower rates than whites in uninsurance. Pathways leading to coverage varied by race/ethnicity. The main findings yielded empirical, theoretical, and policy implications that contributed to health care disparity research.
