Autistic adults experience disparities in physical health and health care access. A major barrier to addressing these disparities is a lack of federal funding for research on this topic. In seeking funding from the National Institutes of Health (NIH), we discovered nodes that contribute to structural discrimination in physical health--related research for autistic adults. To examine this structural discrimination, we systematically searched funded research on all physical health--disparity conditions in autistic adults using NIH RePORTER. Among 61 unique studies, none focused on improving the relevant physical health condition through intervention, programs, or services for autistic adults. Thus, we need updated policies and procedures that support research on physical health disparities in populations with developmental or mental health conditions.
