October 21, 2025 updated by: William B Perkison, The University of Texas Health Science Center, Houston

Improving the Health of Americans Through Prevention and Management of Diabetes, Heart Disease and Stroke - Sustainable Culturally Adapted Nutrition (SCAN) Program

The purpose of the study is to determine the impact of an enhanced, food incentive program [called the sustainable culturally adapted nutrition (SCAN) program], which is integrated with the Diabetes Prevention Program (DPP) and a food prescription framework. The SCAN program aims is to improve participant adherence and the ability to make sustainable behavioral changes to reduce the chances of developing diabetes.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sustainable Culturally Adapted Nutrition (SCAN) Program plus DPP plus Produce Delivery
Participants will be a part of the Diabetes Prevention Program (DPP), and additionally, as a participant in the the SCAN program, will receive live online instructional video sessions and email links that provide additional training information. Participants will also receive produce delivery.
Behavioral: Live instructional video sessions
Three instructional live video sessions will be provided to participants via live videoconferencing. The session will describe fundamentals for preparing produce for cooking, healthy approaches to cooking foods, a review of serving sizes, reading labels, and different classes of health foods. The nutrition education is designed to promote healthy dietary patterns for all by empowering participants to navigate healthy eating through the lens of their own food and cultural experiences. By emphasizing culinary techniques over recipes, instructors can inspire adaptability of culturally familiar flavors and ingredients for a diverse range of ethnicities, abilities, and cooking equipment.
Behavioral: Links to educational videos
This online information will supplement and reinforce the information presented in the live instructional video sessions.
Behavioral: Diabetes Prevention Program (DPP)
The Diabetes Prevention Program (DPP) is a lifestyle change program intended to stop the onset of type 2 diabetes. The program involves Lifestyle Coaches, who help participants make and maintain the lifestyle changes that can help prevent type 2 diabetes. The Lifestyle Coaches share information about diabetes prevention, debunk fitness and health myths, and encourage fitness and healthy eating in regular group sessions. They also work with participants individually on personalized weight loss and exercise goals and action plans, using the group as a source of support and encouragement.
Behavioral: Produce Delivery
The investigators partnered with the Houston Food Bank (HFB) to offer up to 30 pounds of fresh produce twice per month to all DPP participants through a food prescription (Food Rx) program.
Active Comparator: Diabetes Prevention Program (DPP) plus Produce Delivery
Participants will be a part of the Diabetes Prevention Program (DPP) and will also receive produce delivery.
