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:
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.

This study is a cluster-randomized clinical trial designed to evaluate the effectiveness of an enhanced, culturally, socially, and structurally tailored Diabetes Prevention Program (E-DPP) compared to a standard culturally tailored DPP (S-DPP) among African American adults with prediabetes residing in low-income, socially vulnerable communities. The trial will enroll approximately 408 participants across 12 community-based sites (churches), which will be randomized to deliver either S-DPP or E-DPP to minimize contamination across intervention conditions.
Both intervention arms are grounded in the evidence-based DPP lifestyle intervention and incorporate cultural tailoring strategies to improve relevance and acceptability in African American communities. The enhanced intervention builds upon this foundation by explicitly addressing multilevel social determinants that influence engagement in healthy eating and physical activity. Specifically, E-DPP integrates structural supports to improve access to healthy foods and safe, low-cost physical activity opportunities, alongside strategies to address social stigma related to obesity, poverty, and food insecurity.
The E-DPP includes additional components delivered during and between sessions. These include provision of fruits and vegetables during sessions, experiential activities focused on healthy food selection and budgeting, and facilitated linkage to community food resources such as food pantries and assistance programs. Physical activity support includes structured in-session exercise and guidance on accessing community-based physical activity programs. Participants in the E-DPP arm will also receive tailored text messaging designed to reinforce behavior change, promote utilization of community resources, and reduce stigma-related barriers to engagement.
The intervention is delivered over a 12-month period, with assessments conducted at baseline, 6 months, and 12 months. A community-engaged approach informs intervention design and implementation, ensuring alignment with local context and resources. The study is guided by theoretical frameworks that emphasize the role of social and structural determinants in shaping health behaviors and outcomes.
In addition to evaluating intervention effects, the study will examine potential mediators and moderators of weight loss, including social determinant-related stressors, access to resources, and psychosocial factors. A concurrent process evaluation will assess intervention fidelity, dose, participant engagement, acceptability, and feasibility, as well as cost-related considerations. These data will inform identification of key intervention components and support future scalability and dissemination of the enhanced program in underserved communities.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

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.
Behavioral: Culturally-tailored, enhanced adaption of Diabetes Prevention Program
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.
Behavioral: Culturally-tailored, enhanced adaption of Diabetes Prevention Program
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.
