Project LIFT - Promoting Healthy Behavior Through a Wearable Fitness Device and Financial Incentives

Not Applicable

Completed

• Conditions: Kidney Transplant; Complications; Liver Transplant; Complications; Obesity

• Registration Number: NCT03221465
• Lead Sponsor: University of Pennsylvania

Brief Summary

Project LIFT is a randomized, controlled trial that tests the effectiveness of a remotely-monitored, home-based exercise program utilizing wearable fitness trackers to monitor steps taken per day, health engagement questions, and financial incentives. 120 subjects will be randomized into 3 arms: 1) usual care - no fitness tracker or incentive, 2) a fitness tracker + no incentives, and 3) fitness tracker plus financial incentives.

Detailed Description

Obesity is the most common diseases in the United States - an estimated 35% of adults are obese. Among kidney (KT) and liver transplant (LT) recipients, weight gain and obesity is associated with poor graft function. Yet, within a year of transplantation, habituation to a sedentary lifestyle, changes in metabolism, and immunosuppression drugs contribute to an average 4-10 kg weight gain for recipients. Recent innovations in wearable device technology can passively monitor an individual's physical activity. Additionally, incentives and health questions designed using insights from behavioral economics have been shown to motivate device engagement and improvements in health behaviors. A remotely-monitored exercise program could improve behavior change and potentially be durable because it takes advantage of the high motivation for improving health in this population. The objective of this study is to use a randomized, controlled trial to test the efficacy of a home-based exercise program using wearable devices, health engagement questions and financial incentives. Participants in the intervention arm will establish a baseline step count during the first two weeks, followed by a 12-week intervention period and a 4-week follow-up period.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 127

Inclusion Criteria

1. Adult Kidney transplant, Liver transplant, Simultaneous liver-kidney, or kidney-pancreas transplant recipients at the Hospital of the University of Pennsylvania within 2-24 months of transplantation
2. Ability to read and provide informed consent in English to participate in the study
3. Possess a smartphone with a data plan and willing to receive text messages
4. Willing to walk and sync wearable daily during the 2-week run-in in order to determine baseline [for Arms 2 & 3]
5. Willing to provide a final weight at study end.

Exclusion Criteria

1. Inability to provide informed consent
2. Does not have daily access to a smartphone compatible with the wearable device
3. Unable or unwilling to complete the baseline measurements and survey, or perform the exit interview and weigh-in
4. Already enrolled in a financial incentive-based exercise program using a wearable device
5. Use of a wearable accelerometer or pedometer outside of the study protocol for step-tracking; (e.g., Fitbit; using phone step-tracker is acceptable; using existing wearable for cycling or swimming is acceptable)
6. Any other medical conditions that would prohibit participation in a physical activity program
7. Severe vision, hearing, or mobility impairment precluding participation.
