Evaluating a Type 2 Diabetes Prevention Program

Stanford University62 enrolled

Overview

This study aims to test the effectiveness of a Type 2 Diabetes (T2D) prevention program for individuals who have been diagnosed with prediabetes compared to a T2D educational control group. Project health is an obesity prevention program and has produced a 42% to 53% reduction in future onset of overweight/obesity and also produced greater reductions in negative affect compared to assessment-only controls that persisted. Project Health has been adapted to prevent onset of T2D among individuals with prediabetes. The study aims to test the effectiveness of Project Health at reducing BMI, HbA1c levels, increase physical activity and improve glucose control.

Interventions

Project Health will be delivered in six 1-hour group sessions that will be held weekly. In addition, participants will be asked to complete 30 mins of response inhibition and attention trainings once per week between the sessions. This program promotes to retain the gradual lifestyle modification designed to bring energy intake into balance with energy output and the food response inhibition and attention training, but will adapt the dissonance-induction activities to focus on the negative effects of developing T2D in addition to the negative effects of obesity, overeating, and a sedentary lifestyle.

Educational Video ControlOTHER

We selected a T2D management psychoeducational comparison condition. To match Project Health, the educational videos will be delivered in 6 1-hour blocks. The educational group will be instructed to watch videos on nutrition, exercise, and how to maintain general health during the lifespan

Outcomes

Primary Outcomes

Body Mass Index (BMI) - Post-Test

BMI will be assessed at post-test to see which intervention produced greater reductions in BMI

Time frame: post-test (immediately after completion of 6 week intervention)

Body Mass Index (BMI) - 3-Month Follow-Up

BMI will be assessed at 3-month follow-up to see which intervention produced greater reductions in BMI

Time frame: 3-month follow-up

HbA1c at 3-month Follow-up

Participants will complete an HbA1c test at 3-month follow-up to determine their pre-diabetes status
