Interventions

• Culturally-tailored, enhanced adaption of Diabetes Prevention Program — BEHAVIORAL
  This intervention adapts the CDC PreventT2 Diabetes Prevention Program into two 12-month delivery models led by community peer coaches with student support across 22 sessions (16 core, 6 maintenance). Both arms include pre-program outreach, a pre-session addressing diabetes disparities, goal setting and barrier identification, structured sessions with weigh-ins captured in REDCap, review of self-monitoring logs, and guided curriculum delivery. Participants use Wi-Fi scales and fitness trackers to support behavior change. The enhanced arm adds tailored text messaging, resource navigation, food access supports, and culturally tailored physical activity to address barriers and improve engagement and sustainability.

Study Details

The goal of this clinical trial is to learn if an enhanced, culturally, socially, and structurally tailored Diabetes Prevention Program (E-DPP) can improve weight loss and related diabetes risk factors in African American adults with prediabetes living in low-income, socially vulnerable communities. The main questions it aims to answer are: * Does the enhanced DPP (E-DPP) lead to greater percent weight loss at 6 and 12 months compared to the standard culturally tailored DPP (S-DPP)? * How do social determinants (e.g., food insecurity, stigma, access to resources) influence weight loss and engagement in lifestyle behaviors? Researchers will compare a standard culturally tailored DPP (S-DPP) to an enhanced DPP (E-DPP) to see if improving access to healthy food, physical activity, and community resources increases weight loss and improves diabetes-related outcomes. Participants will 1. Attend DPP sessions delivered in community settings (e.g., churches) 2. Receive lifestyle education focused on diet, physical activity, and weight loss 3. Engage in physical activity (including in-class exercise sessions \[E-DPP only\] and community-based options) 4. Receive support for healthy eating, including food deliveries (\[E-DPP only\]), food selection guidance, and referrals to food assistance programs 5. Receive information and support for accessing community resources for food and physical activity

Arms

• Active Comparator: Standard Diabetes Prevention Program (S-DPP)
  Standard DPP (S-DPP) is a 12-month, in-person lifestyle intervention based on the CDC PreventT2 curriculum, delivered by community peer coaches across 22 sessions (16 core, 6 maintenance). Coaches conduct pre-program outreach and a pre-session addressing diabetes disparities, goal setting, and attendance barriers. Each session includes weigh-ins with REDCap capture, review of self-monitoring logs for diet, activity, and goals, and guided delivery of the curriculum. Participants receive Wi-Fi scales and fitness trackers to support weight loss and physical activity tracking. Certain sessions provide information on local, low- or no-cost food and physical activity resources to support and maintain behavior change.
• Experimental: Enhanced Diabetes Prevention Program (E-DPP)
  Enhanced DPP (E-DPP) is a 12-month intervention based on the CDC PreventT2 curriculum that integrates digital tools, community resources, and culturally tailored supports across 22 sessions (16 core, 6 maintenance). Coaches conduct pre-program outreach and a pre-session addressing diabetes disparities, goal setting, and attendance barriers. Sessions include weigh-ins with REDCap capture, review of self-monitoring logs, and guided curriculum delivery. Participants receive Wi-Fi scales and fitness trackers and access tailored text messages with DPP content and resource links. Coaches provide additional messaging support. The model also includes in-class healthy food distribution and culturally tailored physical activity sessions, as well as information on local low- or no-cost resources to support sustained behavior change.
