Use of Wearable Tech to Increase Physical Activity in Inpatient Rehabilitation for Overweight and Obese Patients

Not Applicable

Completed

• Conditions: Obesity; Overweight
• Interventions: Device: Wearable tech without feedback; Device: Wearable tech with feedback; Behavioral: Rehabilitation program

• Registration Number: NCT04031079
• Lead Sponsor: Norwegian University of Science and Technology

Brief Summary

The aim of this project is to evaluate whether use of wearable tech increases physical activity in patients participating in inpatient rehabilitation for overweight and obesity.

Detailed Description

Obesity is a global epidemic with profound consequences for individuals and societies. Physical exercise is important for weight reduction and weight loss maintenance. Use of wearable tech might facilitate physical activity. Here it will be evaluated whether use of wearable tech that gives feedback about the user's activity level, increases physical activity in people participating in inpatient rehabilitation for overweight and obesity. The control group will be wearing the same wearable tech as the intervention group, but they will not receive any feedback about their activity level.

The feedback application will give participants in the intervention group information about the number of PAI they earn each week. PAI is short for Personal Activity Intelligence. One earns PAI points every time heart rate increases: The higher heart rate, the faster one earns PAI. Previous research have shown that those who achieve 100 PAI or more every week over time, live for an average of more than eight years longer than others.

During the study all participants will take part in a traditional inpatient rehabilitation program (lifestyle modification program). The program consist of three periods at the rehabilitation center with time at home in-between. The study will take place during two periods at the center and one period at home. Time spent on physical activity and number of earned PAI's will be counted during the period at home.

Group	Intervention	Description
Wearable tech without feedback	Wearable tech without feedback	This group will be wearing the same the activity measurement device as the intervention group, but they will not receive any feedback about their activity level. They will not have access to the mobile application. They will take part in the same rehabilitation program as the intervention group.
Wearable tech with feedback	Wearable tech with feedback	This group will be wearing an activity measurement device (wristband) and receive feedback about their activity level through a mobile application while taking part in a traditional inpatient rehabilitation program for overweight and obesity (lifestyle change program).

Primary Outcome Measures

Name	Time	Method
Activity level	4 weeks (time period at home between two stays at the rehabilitation center)	Time spent in moderate to vigorous physical activity (minutes per day)
Percentage achieving 100 Personal Activity Intelligence points (PAIs) per week	4 weeks (time period at home between two stays at the rehabilitation center)
Number of PAIs	4 weeks (time period at home between two stays at the rehabilitation center)	mean number of Personal Activity Intelligence (PAI) points achieved per week

Secondary Outcome Measures

Name	Time	Method
oxygen uptake	7 weeks (from inclusion to end of rehabilitation program)	submaximal oxygen uptake measured by the Astrand bicycle test (described in Textbook of work physiology by Astrand from 1986)
Body Mass Index score	7 weeks (from inclusion to end of rehabilitation program)	weight in kilograms divided by height in metres squared
Body weight	7 weeks (from inclusion to end of rehabilitation program)	body weight in kilograms
