Obesity
Conditions
Brief summary
This controlled clinical trial aims to compare the effects of an online program that includes exercise guided by the FITT-VP principle and dietary advice, conducted by fitness coaches, in children and adolescents with obesity with a control group that will be enrolled in conventional in-clinic nutrition and exercise advice. All participants will be monitored for 8 months during the active intervention, and followed by 16 months of observation. The study will evaluate the following parameters between groups: BMI, anthropometry, blood biochemistry panel (ALT/AST, lipids, uric acid, HOMA-IR, HbA1c), food frequency questionaire, household survey, satisfaction survey, and adverse events.
Interventions
BEHAVIORALOnline program that includes exercise guided by the FITT-VP principle and dietary advice
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.
BEHAVIORALConventional in-clinic nutrition and exercise advice and self-control
Physicians provide instructions on exercise and nutrition (total daily calorie intake) for the patients to conduct self-control for 16 weeks.

Inclusion criteria
1. Simple obesity: Body mass index (BMI) between +2SD and +3SD of the reference range: based on the "Standard Deviation Curve of BMI for Children 0-18 Years of Age in China", which was developed by the Physical Development Survey of Children in Nine Provinces/Cities in 2005; 2. Not participating in other weight management programs currently or in the 3 months prior to the study; 3. Accepts to participate and signs informed consent.
Exclusion criteria
1. Currently taking or planning to take medications or interventions that affect body weight during the study period (32 weeks) 2. Obesity caused by other medical conditions. For example, hypothalamic-pituitary disease, hypothyroidism, growth hormone deficiency, Cushing's syndrome, obesity-related syndromes. 3. Comorbidity with other chronic diseases. E.g. psychiatric diseases, respiratory diseases, gastrointestinal diseases, rheumatic diseases, hepatic and renal insufficiency, chronic infectious diseases; 4. Presence of abnormal laboratory values at the time of screening indicating a clinically significant underlying disease or condition that may prevent the subject from participating in the study; or presence of abnormalities in the following laboratory tests: alanine aminotransferase (ALT) greater than 5 times the upper limit of normal, serum creatinine (Scr) greater than 1.5 times the upper limit of normal. 5. Contraindications to physical exercise or exercise-related risks. For example, history of asthma, history of hypoglycemia/diabetes, history of heart disease, history of cardiovascular disease, fracture/surgery/planned surgery within the last 1 year, psychomotor retardation, motor system defects/disabilities, previous history of exercise intolerance;
