Intervention for Weight Change Post-Bariatric Surgery

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

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.

Standard Care

Subjects in this arm will receive the standard care that is provided by their bariatric surgical team following bariatric surgery.

Behavioral - Technology-based Intervention (TECH)

Dietary recommendations: based on the subjects' baseline body weight, with calorie goals ranging from 1200-2100 kcal/day. The physical activity component: unsupervised home-based exercise program. Intensity/Mode: aerobic physical activity recommended at a moderate intensity. Prescription: progress to 250 min/wk by 13th week of the intervention. Self-monitoring: Jawbone UP3 System includes a wearable device to monitor physical activity and energy expenditure that will transmit real-time feedback more on
