A Pilot Factorial Trial of an Integrated Lifestyle Intervention

The PreventT2 curriculum is based on the original 2002 Diabetes Prevention Prevention (DPP) trial and follow-up studies. It promotes modest weight loss (5-7%) and increased physical activity through a lifestyle change program and also reflects new literature on self-efficacy, physical activity, and diet. There are 16 modules that will be delivered over 6 months. Participants will receive a calorie goal and be asked to count calories in order to reduce their caloric intake.

The Move physical activity support program group-based classes are based on Self-Determination Theory and encourage improvements in autonomous motivation for physical activity. These group-based classes are integrated within the Prevent T2 program curricula.

Participants will receive 6 months of the Peloton fitness membership. This includes access to livestream and on-demand fitness classes including walking, strength training, yoga, meditation, stretching, etc.

Participants will receive access to positive mental guided imagery recordings. Recordings describe a pleasant experience while walking and range from 2-8 minutes in duration.

Participants will meet individually with their class instructor to receive personalized recommendations on how to incorporate messages from the Move group-based classes into their daily lives. Sessions are based on Self-Determination Theory and will last approximately 45 minutes.
