Nudge-Based Exercise for Obese Adolescents

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study will compare a standard exercise program to a nudge-based program in about 140 adolescents aged 10–19 with obesity. Participants are enrolled in two groups by admission order and will undergo either standard exercise or an 8-week nudge-based plan designed to make starting and maintaining activity easier through behavioral strategies, reminders, peer support, progress feedback, and small incentives. The nudge program combines in-hospital sessions with home-based tools, activity tracking, and online follow-up. Primary outcomes include changes in body mass index and physical activity levels over the study period. The trial is conducted at Nanjing Children’s Hospital in China and is led by the same institution, with no listed collaborators.
