About this study
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Wearable tech with feedbackDevice
an armwrist device measuring physical activity level. The user will receive information about their physical activity level through their smartphone
Wearable tech without feedbackDevice
an armwrist device measuring physical activity level, no reporting back to the user
Rehabilitation programBehavioural
traditional inpatient rehabilitation program for overweight and obesity (lifestyle change program)
| Study group | Role | What they receive |
|---|---|---|
| Wearable tech with feedback | Experimental | 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). Receives: Device: Wearable tech with feedback; Behavioral: Rehabilitation program |
| Wearable tech without feedback | Active comparator | 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. Receives: Device: Wearable tech without feedback; Behavioral: Rehabilitation program |

Body weight
body weight in kilograms
Measured: 7 weeks (from inclusion to end of rehabilitation program)
Body Mass Index score

Questions about this trial
What is this clinical trial studying?
A study testing Wearable tech with feedback, Wearable tech without feedback and Rehabilitation program in people with Obesity and Overweight, run by Norwegian University of Science and Technology at 1 site in Norway.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Activity level (time frame: 4 weeks (time period at home between two stays at the rehabilitation center)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2020.
