Assistant Professor Julia Sheffler, Ph.D., led a multi-trial analysis of two pilot studies exploring the factors that help older adults at increased risk for dementia adhere to a nutrition-based lifestyle program. Researchers found that engagement is shaped by cognitive health, mental well-being, financial resources and living environment.

Key Insights:

• Better cognitive functioning was linked to stronger program engagement.
• Depressive symptoms, poor sleep, and physical health challenges were associated with lower adherence.
• Higher income and education supported more consistent participation and engagement.
• Rural living and limited access to healthy foods created additional barriers.

Why It Matters:
Lifestyle interventions can help reduce dementia risk, but success depends on more than individual motivation. Flexible program structures, social support, and strategies that address financial or access challenges may improve engagement and health benefits long-term.
