The Phresh study, a longitudinal research project conducted by the University of Pittsburgh, has been abruptly cancelled by the Trump administration as part of broader cuts affecting thousands of medical research grants at the National Institutes of Health. The study, which began over a decade ago examining food deserts and their health effects, had evolved into a significant data collection effort on cognitive health in two low-income, predominantly Black neighborhoods near the university.
Researchers were given 90 days to shut down operations, significantly shorter than the timeline originally planned. This abbreviated timeline prevents the completion of cognitive assessments for approximately 600 study participants, who had been promised results from their cognitive testing. The assessments were designed to detect changes associated with Alzheimer’s disease and dementia, conditions for which early diagnosis is considered critical for treatment. The study’s principal investigator, Tamara Dubowitz, stated that the inability to complete this analysis represents a broken commitment to participants who had participated in extensive data collection over years.
The Phresh study represents a unique research design within Alzheimer’s investigations. It was originally structured as a natural experiment comparing two neighborhoods, with one slated to receive a new grocery store and the other not. The study’s random selection of addresses from each neighborhood differs from typical research recruitment methods that rely on interested volunteers. Early findings indicated that health improvements in one neighborhood were linked to broader neighborhood investment rather than grocery store access alone.
The cancellation occurs against the backdrop of documented racial disparities in Alzheimer’s research. Black Americans experience nearly double the risk of developing Alzheimer’s dementia compared to other populations, according to the Alzheimer’s Association. However, existing research on the disease has historically skewed toward white and affluent participants, with studies reporting race comprising a small fraction of Alzheimer’s research literature. The termination of this study eliminates a significant opportunity to examine disease risk factors related to neighborhood conditions and structural factors affecting older Black Americans.
Administration officials and supporters have characterized cancelled studies as either diversity-focused initiatives or lacking scientific merit, while critics characterize the funding cuts as retaliation against research that does not align with administration priorities.
