Abstract
Research has documented disparities in health care and access for people with intellectual and developmental disabilities (IDD) and people in racial and ethnic minority groups. Though both populations are underserved, the additive impact of being both a member of a racial/ethnic minority and having IDD is largely unknown. This study uses data from a nationally representative survey to explore health service utilization among adults with IDD belonging to minority racial/ethnic groups compared to adults with IDD who are White. The results of this study indicated that racial/ethnic minority groups are disadvantaged in several essential areas of health care utilization and that Hispanic Americans are particularly underserved. Additional research is needed to identify and address the factors driving this difference.
