Effect of a Technology-Based Intervention on Weight Change Post-Bariatric Surgery

Stopped early · Not applicable

Conditions studied: Motor Activity, Weight Loss

In brief

The primary aim of this study is to examine the effect of applying a minimal contact technology-based intervention (TECH) at 1-year post-bariatric surgery on weight change compared to Standard Care. Forty participants at 1-year post bariatric surgery will be randomized to TECH or Standard Care for a period of 6 months (12 to 18 months post-surgery). Analyses will be conducted to compare these interventions for differences in body weight, body composition, fitness, physical activity, engagement, psychosocial measures, and intervention cost and cost-effectiveness of each approach. TECH will consist of a wearable monitor that provides feedback on energy expenditure and physical activity, electronic tracking of dietary intake, and integration of an electronic scale to provide comprehensive feedback to the participant on all components of weight management. TECH participants will receive a monthly telephone call from the intervention staff to provide guidance on their weight management efforts.
