Abstract

Objective: Are three app-controlled feedback devices, tested against a simple pedometer in a weight reduction program, supporting sustainable therapy success and quality of life (QoL)? Methods: In this multi-centre randomised controlled study adults with obesity (n = 89, m = 46.5 years, women n = 54), achieved high weight loss (from 42.7 kg/m(2) to 35.2 kg/m(2)) while completing the first three month of the OPTIFAST (R) 52-program. Thereafter the intervention group (IG) used feedback devices (BIA scale, blood pressure monitor, step counter), the control group a mechanical pedometer without app for another year. Intention-to-treat analysis (ITT) and As-treated analysis (AT) were carried out. Results: Feedback devices had a positive effect on fat-loss and secondary study objectives like QoL, leading to a better sustainability of these improvements. Participants in IG (AT for t2-t0) had improvements for Waist-to-Height-ratio (WHtR) and physically and mentally quality of life. Conclusion: The results are presumably based on an increase in self-efficacy and the experience of control. Future studies should be preceded by a pilot study to analyse acceptance problems.
