It's time for the NIH to formally designate people with disabilities as a US health disparity population.

This commentary discusses the implications of the report and recommendations of the Working Group on Diversity's Subgroup on Individuals with Disabilities, recently endorsed by the full Advisory Committee to the Director (ACD) of the National Institutes of Health (NIH). We suggest that one of these recommendations, the formal designation of people with disabilities as a US health disparity population, can be enacted immediately, which would spur new federal investment in disability-based disparities research.
