Family Diabetes Prevention Program Pilot Study

Summary

This study will examine the feasibility and acceptability of a family-oriented augmentation of the Diabetes Prevention Program lifestyle intervention (DPP), called the Family DPP. It will also preliminarily examine adult and child health and health behavior outcomes. The DPP is a 12-month, group-based lifestyle intervention for adults at high-risk for type 2 diabetes, in which adult participants learn skills and strategies to achieve the program's goals of 5% weight loss and 150 minutes/week of moderate-vigorous physical activity. The Family DPP will consist of all elements of the evidence-based DPP, along with augmentations including additional child-focused sessions in which adult participants will learn about principles and strategies for promoting healthy lifestyle behaviors in children, ages 5 through 12 years. Children may participate in certain child-focused sessions, too. The non-randomized pilot feasibility study will consists of 2 arms/groups: 1) the concurrent "control" group, consisting of adults who are enrolled in the DPP; and 2) the "intervention" arm, in which the adult participants will engage in the Family DPP (and children may participate in certain aspects of the Family DPP focused on children). The study will recruit 10-15 adult-child dyads, for the "intervention" groups, and 10-15 adults for the concurrent control group. In addition to data collected from adult participants as a routine part of the DPP, the study will examine additional adult health behaviors and health outcomes and child health outcomes (change in body mass index z-score) and health behaviors at baseline, 6 months and 12 months (program end) among participants in the "intervention" group.

Interventions

BEHAVIORAL

National Diabetes Prevention Program Lifestyle Intervention (DPP)

The National Diabetes Prevention Program lifestyle intervention (DPP) is a 12-month long, group-based lifestyle intervention for adults at high-risk for type 2 diabetes. The DPP will be delivered by certified coaches from the Johns Hopkins Brancati Center. The program uses the CDC's Prevent T2 curriculum, with a total of 32-34 sessions delivered over a 12-month period. In the initial "core" period (first 6 months), there are at least 16 sessions delivered on a weekly basis. In the "post-core" period, additional (at least 6) sessions are offered over a 6 month period. Sessions are delivered either in-person or via a virtual synchronous platform (Zoom).

BEHAVIORAL

Family Diabetes Prevention Program (Family DPP)

The Family DPP has been developed as an augmented version of the National Diabetes Prevention Program Lifestyle Intervention (DPP). It includes all elements of the 12-month, group-based DPP lifestyle intervention, led by a CDC certified-coach using a CDC-approved curriculum (involving around 32-34 sessions). The augmentations of the Family DPP supplement the DPP's sessions to additionally address barriers to adults' own lifestyle change efforts related to being a caregiver of children AND to introduce basic concepts regarding healthy child habits related to dietary intake, physical activity and screen time, and sleep. The Family DPP will involve thus additional sessions that will be delivered to the adult DPP participant, and in which children, ages 5 through 12, may also be engaged.
