- Brief Summary
Overweight and obesity are today considered among the most important health risks facing humanity with more than one in two adults overweight or obese in western countries. In addition, Type 2 diabetes mellitus (T2DM) is a common comorbidity associated with overweight and obesity and counts for 5% of the French population under 65 years of age and 15% in people over 65 years old. Despite the accumulation of scientific evidence supporting the benefits of physical activity, obese and diabetic people remain insufficiently active and current programs struggle to engage and sustain physical activity of patients over long periods of time. It is therefore urgent to develop interventions that can effectively change individuals' behavior. In this context, "e-health" interventions and gamification appear to be a particularly promising avenue to improve physical activity and reduce attrition rates of current programs.
This clinical trial aim to test the effectiveness of a digital intervention based on gamification and teamwork in comparison to a supervised physical activity program. The investigators hypothesized that the intervention will be efficient by the development of a self-determined motivation through the process of gamification on the one hand. On the other hand, through the in-group collaboration with other people who share the same stigmatized criteria that will help participants to overcome weight stigmas, acting generally as physical activity barriers.
- Detailed Description
This trial is a randomized, two-arm intervention design that will examine the efficacy of a digital group-based intervention based on gamification and teamwork among obese and T2DM patients. The experimental arm will be compared to an active control group representing the traditional care program (supervised physical activity).
The digital intervention is composed of four components within a smartphone application: a) a gamification of PA, b) a remote adapted physical activity program with telecoaching sessions, c) an interface for exchange and conversation and, d) an activity monitoring tool. Accelerometer data, self-reported PA, body composition, and physical capacities will be assessed before, at the end of the intervention and then at the issue of a 6-month follow up. To advance our understanding of complex interventions like gamified and group-based ones, this study will explore several psychological mediators relative to motivation, enjoyment, in-group identification, or perceived weight stigma. Finally, to assess a potential superior efficiency compared to the current treatment (face-to-face supervised PA), this study will include a cost-utility analysis between the two conditions.
