Assistant Professor Julia Sheffler, Ph.D., led a multi-trial analysis of two pilot studies examining factors that influence adherence and engagement in a nutrition-based lifestyle intervention among older adults at increased risk for dementia.

The study included contributions from FSU College of Medicine medical student Giovanna Mompremier, MPH, (Class of 2028) and Bridge to Clinical Medicine master’s student Viviana Gutierrez Caimary, B.S., reflecting the college’s emphasis on expanding meaningful research opportunities for students early in their training.

The research found that intervention participation was shaped by several interconnected factors, including cognitive health, mental well-being, financial resources and home environment. Participants with stronger cognitive functioning were more likely to remain actively engaged in the program, while depressive symptoms, poor sleep and greater physical health challenges were associated with lower adherence.

Findings suggest that although lifestyle interventions may help reduce dementia risk, successful participation often depends on addressing broader social and environmental challenges. Flexible program structures, stronger social support and strategies that improve financial or food access may help increase long-term engagement and potential health benefits.
