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.
