SMARTer Weight Loss Management

Summary

The SMARTer trial will be a three-arm, randomized controlled non-inferiority trial that compares the optimized, adaptive SMARTer intervention, fixed DPP, and Self-Guided (Control). The trial will address whether a scalable, stepped-care intervention can stand up to gold-standard DPP by achieving comparable weight loss at a lower cost. Alongside evaluation of clinical non-inferiority, a comprehensive economic evaluation will inform relative affordability. Cost information is important to inform treatment policy and change standard of care, but is sorely lacking for behavioral interventions. The SMARTer intervention reduces costs by initially offering minimal intervention to all and stepping up to offer more costly treatment components only to non-responders who fail to attain the target weight loss. A rigorous economic evaluation planned and designed alongside the SMARTer trial will provide an accurate, robust head-to-head comparison of costs, cost-effectiveness, and projected lifetime health care costs between the three arms.

Interventions

BEHAVIORAL

Adaptive SMARTer intervention (SMARTer)

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 loaned a Fitbit tracking device and a wireless Bluetooth scale for 12 months.

BEHAVIORAL

Diabetes Prevention Program (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.

BEHAVIORAL

Self-Guided Treatment (Self-Guided)

Provides paper and internet resources tailored to geographic area, educating on leading a healthier lifestyle, including information on wellness and physical activity. Will have physical measures taken at baseline, 3 months, 6 months, 9 months, and 12 months.
