Optimization of a mHealth Behavioral Weight Loss Intervention for Young Adults
In Brief
A clinical study evaluating Core, Standard Diet Monitoring, and 9 other interventions for Obesity. Completed, enrolled 759 participants across 1 site.
Detailed Summary
Mobile obesity interventions have the potential to reach a diverse population in need; however, while effective, have not resulted in weight losses obtained in in-person interventions. Newer digital approaches called Just-in-Time Adaptive Interventions (JITAI) that offer adaptive, personalized feedback 'when needed' and in 'real time' offer an opportunity to use digital health tools "just in time". This study seeks to identify the optimal components of a comprehensive weight loss JITAI that results in weight losses that meet or exceed those in existing remotely delivered interventions.

Timeline
Interventions
Behavioral weight loss core includes behavioral lessons, activity tracker, daily self-weighing, weekly tailored feedback summary.
Standard monitoring using smartphone tracking of all calorie intake.
Simplified diet monitoring using smartphone tracking of red foods using a traffic light approach.
Physical activity goals that adapt once each day using the participants' data derived from activity tracker.
Physical activity goals that adapt once each week using the participants' data derived from activity tracker.
Message timing is fixed and evaluated at specific times each day to determine message eligibility.
Message timing is adaptive and derived from individual user data to determine message eligibility.
Decision rules to determine eligibility to receive just-in-time messages consider participant's recent behaviors.
