Two significant programs that invested in research on diabetes, dementia, obesity, and kidney disease have been terminated since the start of the Trump administration. The programs focused on addressing chronic health problems and were led by Robert F. Kennedy Jr., the secretary of Health and Human Services. The termination of these programs has led to lost opportunities to address public health issues. One program, the Diabetes Prevention Program, was studying the link between diabetes and dementia and had started advanced cognitive testing for evidence of dementia in patients. Another program, the Pediatric Scientist Development Program, aimed to ensure that chronic childhood diseases were included in medical research and was terminated due to a lack of diversity in its grant proposal.
