Fangshan Active Nutrition Initiative
Sponsor: Peking University
Summary
The goal of this study is to evaluate the effectiveness of a school-based weight management intervention delivered through a digital platform (WeChat) in preventing excessive weight gain and improving health behaviors in school-aged children in Fangshan District, Beijing. The main questions it aims to answer are: Does the intervention group show a significantly lower mean increase in BMI, body fat percentage, and waist circumference compared to the control group? Does the intervention group show a significantly lower obesity rate and new obesity incidence compared to the control group? Does the intervention group show significant improvements in healthy eating, sedentary behavior, sleep, physical activity, and physical fitness test scores compared to the control group? Researchers will compare children in intervention schools (who receive the multi-level intervention targeting students, families, and schools, supported by a digital platform for behavior monitoring and feedback) to children in control schools (who do not receive the intervention during the study period). Participants in the intervention group will: (1) attend 10 student health education sessions; (2) have their physical activity at school increased to 60 minutes/day of moderate-to-vigorous activity; (3) have parents attend health education lectures and use a WeChat platform to receive health information, log child health data, and receive automated feedback; (4) have their height, weight, waist circumference, and body composition measured monthly by school health staff; and (5) be followed with assessments at 6, 12, and 24 months.

Digital Intelligence Platform-based Multi-level Weight Management
This multi-level behavioral intervention integrates digital technology with school-based health promotion to address childhood obesity. Key components include: Digital Hub: A WeChat-embedded platform for real-time behavior monitoring (diet, physical activity, sleep) and automated monthly feedback reports for parents. Structured Curriculum: Ten 40-minute health education sessions for students delivered every 2-3 weeks, complemented by interactive "hand-in-hand" homework assignments. Physical Activity: Daily school-based promotion to ensure ≥60 minutes of MVPA, emphasizing outdoor and resistance exercises. Environmental Policy: Implementation of school-wide restrictions on sugar-sweetened beverages (SSBs) and unhealthy snacks. Parental Engagement: Two dedicated health seminars and regular push notifications of evidence-based health tips via the digital platform. The intervention is distinguished by its multi-sectoral approach (connecting students, parents, and school staff) and it
