Description

Nearly half of adults in the United States have or are at risk of developing type 2 diabetes. The overall goal of this community-engaged research is to examine the efficacy of an innovative couple-based lifestyle intervention to prevent type 2 diabetes that is applicable to a broad range of partnered adults in the United States.

  • Individual intervention condition (PreventT2) (Behavioral)
    PreventT2 will be delivered by a team of trained CDC National Diabetes Prevention Program (NDPP) Lifestyle Coaches to adults at high risk for diabetes. The 2021 version of the lifestyle intervention curriculum to be used is freely available from the CDC.

    PreventT2 Together will be delivered by a team of trained CDC National DPP Lifestyle Coaches to adults at high risk for diabetes and their partners.
