Summary

This study tests a school-based weight management program using a WeChat digital platform to help children in Fangshan District, Beijing, avoid excessive weight gain. About 1,400 children in grades 2 and 3 will either receive the program (health classes, daily physical activity, parent education, and digital monitoring) or continue as usual. Researchers will track changes in BMI, body fat, and health behaviors over 24 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Digital intelligence platform (WeChat-based) for behavioral weight management
What this could lead to
If successful, this could provide a scalable, low-cost way to prevent childhood obesity in school settings.
What could go wrong
This is an early-stage study with no results yet. The intervention relies on school and parent engagement, which may vary, and the digital platform's effectiveness is unproven.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Schools will be selected based on the consent of primary leadership, demonstrated cooperation, and availability of necessary personnel (e.g., school health professionals). * Classes will be limited to grades 2 and 3, with teachers showing strong willingness to collaborate. * Both parental informed consent and child assent are required for participation. Exclusion Criteria: * Schools will be excluded if they cater to special populations (e.g., schools for children with disabilities), are involved in other obesity-related interventions within the specified timeframe, or plan to close or relocate within two years. * Children will be excluded if they have histories of major organ diseases (e.g., cardiac, pulmonary, hepatic, or renal conditions), special diets (e.g., vegetarian), pathological eating disorders, physical limitations affecting activity, or obesity due to endocrine disorders or medication side effects.
