Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to investigate the effect of using new app-based technology to increase the level of physical activity, compared to conventional postoperative information given to patients undergoing bariatric surgery. The hypothesis is that the intervention, i.e. using the new technology, will have a greater positive effect on levels of physical activity and outcomes of weight loss than conventional postoperative information.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

App-technology group

App-technology to increase physical activity Participants in the intervention group (App-technology) will use a newly developed smartphone application ("app") in which the participants are able to register their daily physical activity in bouts of 10 min and their intake if supplementary vitamins. They will also be able to set personal goals every week for the level (minutes) of physical activity and get feedback every week in whether they fulfilled the goal or not. They will also get feedback on the intake of supplementary vitamin intake.

Group Type EXPERIMENTAL

App-technology to increase physical activity

Intervention Type BEHAVIORAL

The application will send daily reminders to register and notices with information about the health benefit of physical activity, medication, supplementary vitamins and diet after surgery

Control group

The control group will receive standard information about the benefit of physical activity after surgery.

Group Type NO_INTERVENTION

No interventions assigned to this group
