C166 - PreventT2 Together: Protocol for a Randomized Control Trial of Couple-based Lifestyle Intervention to Prevent Type II Diabetes
Time: 05:00 PM - 05:50 PMTopics: Diabetes, Multiple Health Behavior Change
Poster Number: C166
Over 38 million Americans have type 2 diabetes, a chronic condition associated with many complications and poor health outcomes such as dementia, cardiovascular disease, and early mortality. Health behaviors such as improving nutrition and increasing physical activity prevent or delay the development of type 2 diabetes among those at risk. Individuals’ romantic partners play a key role in lifestyle change. Guided by the Obesity Related Behavioral Intervention Trials (ORBIT) model, we adapted the PreventT2 National Diabetes Prevention Program (National DPP) curriculum for delivery to couples, PreventT2 Together, which was approved as a CDC-recognized alternate National DPP curriculum. This poster will present a work in progress, extending a pilot trial (2023-2024) of PreventT2 Together to a larger NIDDK-funded phase II efficacy trial. Key areas of emphasis will be on the planning and design features of the intervention and recruitment strategies to increase the likelihood of enrolling a sample inclusive of populations experiencing health inequities related to diabetes.
We will recruit 162 couples (324 total participants) in waves over the course of approximately 3 years (2025-2028). To reach groups that have been underrepresented in diabetes prevention work, recruitment will include clinic-based population health management and place-based community-engaged approaches with service providers that have established trust in local communities experiencing inequities. We will include couples in which at least one partner is at risk for type 2 diabetes and eligible for the National DPP. Couples will be randomized (1:1) to either PreventT2 Together, or the individually-based PreventT2 curriculum.
At pre and post, participants will complete 7-day objective moderate-to-vigorous physical activity (MVPA) assessments with daily reported health behavior and relationship functioning measures. Self-report questionnaires will be completed monthly during the year-long intervention including pre and post assessments. MVPA, weight, and attendance data will be collected at each intervention class.
We will use multilevel models to evaluate our hypotheses that: (1) PreventT2 Together is efficacious, (2) target partners’ perceptions of their relationship will be a moderator (i.e., baseline relationship satisfaction) and a mechanism (i.e., increases in perceived partner support) of lifestyle change, and (3) the intervention will have high retention and broad reach.
