Summary
This project aims to improve diabetes prevention outcomes among underserved African Americans by integrating culturally tailored healthy food delivery, on-site physical activity, and community resource linkages into an enhanced Diabetes Prevention Program (DPP) model.
What they want
The project proposes a cluster randomized controlled trial of 408 pre-diabetes mellitus (pre-DM) African American participants recruited from churches in high-risk communities. Participants will be assigned to either a standard, culturally tailored DPP (S-DPP) or a culturally tailored, enhanced DPP (E-DPP). The E-DPP will address systematic barriers to food access, healthy eating, and physical activity over 12 months. The study will examine the effects of E-DDP on weight loss and secondary outcomes, identify key mediators/moderators of weight loss, and conduct a process evaluation of the E-DDP.
Deliverables
- Examination of effects of E-DDP on percent weight loss (primary outcome) and secondary outcomes (food and nutrition insecurity, healthy eating, physical activity, DPP attendance, hbA1c, and blood pressure) at 6 and 12 months
- Identification of key mediators/moderators related to weight loss among AA participants at 6 and 12 months
- Process evaluation to examine E-DDP acceptability, feasibility, fidelity, cost-effectiveness, and the link between program delivery and outcomes
- Insights for national scalability and long-term sustainability of the model
- Information to inform future policy and practice at the national level for diabetes prevention
