Couple-Based Lifestyle Program to Prevent Type 2 Diabetes

This trial is testing a lifestyle program called PreventT2 Together, designed to help prevent type 2 diabetes by working with couples instead of individuals alone. The study compares two approaches: one where only the person at risk for diabetes receives the program, and one where both romantic partners participate together. Researchers want to see if having your partner involved helps you stick with the program and achieve better health results.

Nearly half of Americans are at risk for type 2 diabetes, and lifestyle changes are the best way to prevent it. However, people often struggle to stay in prevention programs. This trial exists to test whether including romantic partners in the program helps people stay committed and actually makes the program work better in real-world settings, especially for communities that have been hit hardest by diabetes.
