Can a smartphone and pedometer help people get fitter before bariatric surgery?
NCT ID NCT03963986
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial investigates whether a remote digital support program, including a connected pedometer and online coaching, can help people aged 30–50 who are scheduled for bariatric surgery become more physically active in the months before their operation. Participants use a digital platform and receive motivational interviews by phone or video. The study compares their activity levels to those who do not use the digital tool, measuring changes at 4, 10, and 16 months.
