Compared to the general population, people with intellectual and developmental disabilities (IDD) face worse health outcomes, and outcomes are even worse for children and adults with IDD from minoritized populations. Examining the intersection of people with IDD from minoritized groups is critical to understanding appropriate policies and services that promote health among all people with IDD. People with IDD from minoritized racial and ethnic groups have greater exposure to detrimental social determinants of health, which leads to poor access to adequate healthcare and poor health outcomes. Policies that aim to improve health outcomes among people with IDD and that are related to their disability and appropriate accommodations are not enough. Policies need to address poverty in families, racism and discrimination, poor housing, and other social determinants that are more prevalent among minoritized populations. Most research on racial and ethnic disparities among children and adults with IDD has been conducted in the United States. While there is emerging research globally on racial and ethnic disparities, there a paucity of this research in the field of IDD. Furthermore, there may be detrimental health effects for other minoritized groups, such as religious minorities, but research is lacking in this area. Clearly, more research on these intersections is needed in the global context.
