Online Exercise Program and Dietary Advice (FITT-online) for Children and Adolescents With Obesity

"1. Week 1: Children received 2 sessions of exercise initiation and 1 session of small group exercise training (45 minutes) with 4\~6 peers.~2. Weeks 2 to 16: 3 small group exercise sessions per week (45 minutes, 4-6 peers) of moderate-to-vigorous physical activity (MVPA). Effective exercise time was assessed by the time subjects reached the heart rate corresponding to the exercise intensity (64-95% of maximal heart rate), as measured by the instantaneous heart rate recorded during each exercise session. The type of exercise was a combination of aerobic, resistance, and flexibility exercises (time ratio 2.5:1:1).~3. Dietary guidance was provided concurrently during the 16-week intervention period: by establishing a WeChat group for caregivers and uploading daily pictures of the day's food to the group, the group's health coaches provided daily targeted dietary guidance."

Physicians provide instructions on exercise and nutrition (total daily calorie intake) for the patients to conduct self-control for 16 weeks.
