Walking for a cause: study tests if games and charity boost family fitness
NCT ID NCT04942535
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This study tested whether social incentives like gamification and charity donations can help low-income families increase their physical activity. Nearly 800 participants from the Philadelphia area wore Fitbits and formed family teams. Each week, a random family member's step goal determined if the team kept points or lost them, with the chance to donate to charity. The goal was to see if these strategies could boost daily step counts over 12 months.
