EVO: Elements Vital to Treat Obesity Study
Study Details
Study Description
Brief Summary
The overall objective of this study is to evaluate the first rigorously optimized, remotely delivered treatment for obesity against the current gold standard treatment in a head-to-head randomized controlled trial. The investigators will be comparing the previously developed and optimized behavioral weight loss intervention (APP) to the Diabetes Prevention Program (DPP), to evaluate program weight-loss success and cost-effectiveness.

Detailed Description
The proposed study seeks to determine if the APP program is an effective, resource-sensitive strategy to manage weight for obesity, as compared to the DPP program. During the 24-week active intervention phase, participants will be randomized to one of two treatments: 1) APP, wherein participants receive calorie, fat, and physical activity goals via a Smartphone application for self-monitoring, online educational readings, and biweekly sessions with a Health Promotionist; or 2) DPP, wherein participants are guided to self-monitor their physical activity, food intake, and weight via a participant log, and are guided through 16 sessions by a Health Promotionist. Assessments to track progress will occur remotely at the 3-month, 6-month, and 12-month time points of the program.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Smartphone App Participants (APP) Smartphone application, diet and activity goals, online lessons, brief remote sessions with a Health Promotionist |
Behavioral: Smartphone App Participants (APP)
Participants will receive calorie, fat, and physical activity goals, a Smartphone application for self-monitoring their diet, activity and weight, online educational readings, and brief bi-weekly remote health sessions with a Health Promotionist. They will also be provided with a wireless bluetooth scale and portable blood pressure machine.

Experimental: Diabetes Prevention Program Participants (DPP) Participant program manual, diet and activity logs, hour long remote sessions with a Health Promotionist |
Behavioral: Diabetes Prevention Program Participants (DPP)
In accordance with the Center for Disease Control curriculum, participants will receive a participant log for tracking physical activity, food intake, and weight, a paper participant guide with worksheets, logs, and psycho-educational materials, and 16 hour long remote sessions with a Health Promotionist. They will also be provided with a wireless bluetooth scale and portable blood pressure machine.
