Interventions for Sustainable Weight Loss in Military Families

Abstract

Objective and Study Design: Our objective was to evaluate the efficacy of a novel lifestyle intervention, Healthy Weight for Living (HWL), versus a modified Diabetes Prevention Program (m-DPP) over 12 months. We conducted a parallel-group randomized trial comparing HWL with m-DPP. Participants were adults with overweight or obesity who were dependents of active duty or retired military personnel (N = 121 HWL; N = 117 m-DPP), recruited from 5 states in the U.S. The interventions were implemented as cost-free group programs by registered dietitians, primarily using videoconferencing. HWL was based on a new health behavior change model emphasizing hunger management and the development of healthy food preferences and was operationalized without required daily food and physical activity logging. m-DPP was a standard DPP implemented with increased counselor contact time. The primary outcome was 12-month weight change; additional outcomes were 6-month changes in cardiometabolic risk factors, self-reported health, and adherence and biobehavioral metrics. Intention-to-treat and completers-only analyses were performed using linear mixed models. Results: Participant retention did not differ between groups (72% vs 66% for HWL and m-DPP at 12 months; P = 0.30). Adjusted group mean changes in energy intake and duration of physical activity also were not significantly different, but HWL participants reported higher adherence to their dietary composition recommendations for reduced glycemic index and glycemic load and increased dietary fiber and protein (P = 0.03 to 0.001). Adjusted 12-month weight loss among completers was 7.8 kg (95% confidence interval [CI]: 6.2, 9.4) for HWL and 6.9 kg (95% CI: 5.1, 8.6) for m-DPP (P = 0.43 for the comparison); 38% of HWL and 30% of m-DPP participants achieved 10% weight loss (P = 0.32).
