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

Study Overview
=================
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.

| Active Comparator: Wearable tech without feedback<br>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. | Device: Wearable tech without feedback<br>* an armwrist device measuring physical activity level, no reporting back to the user<br>Behavioral: Rehabilitation program<br>* traditional inpatient rehabilitation program for overweight and obesity (lifestyle change program)<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

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

Secondary Outcome Measures

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