Obesity Prevention in School-aged Children

Condition(s) studied

Investigational drug(s) / intervention(s)

multicomponent, tiered intervention: this intervention is a multi-level collaborative health management system-a digital health platform with four core modules: the Health Education Module, the Growth Monitoring Module, the Health Behavior Module, and the Home-School Partnership Module. The platform facilitates collaboration among schools, families, and hospitals as follows: Schools utilize the platform to manage tasks outlined in health policies, such as delivering educational content, monitoring student activity and diet, and recording monthly height/weight measurements via the Growth Monitoring Module. Families access the platform to receive multi-format health education, set goals, and review personalized feedback. The Home-School Partnership Module also enables communication for motivational interviewing sessions conducted by professionals offline or by phone. Hospitals leverage the platform to provide professional guidance and medical support, ensuring interventions are medically sound.

Study summary

This cluster-randomized trial will develop and test an intervention technology for school-aged children. The program combines digital health technology and personalized behavior intervention through a WeChat platform.

Our main question is: Does this integrated approach improve obesity related outcomes and behaviors in children?

Investigator will:

* Compare children receiving the program with those receiving usual care.
* Track physical measures and health behaviors to measure effectiveness of intervention.
* Evaluate the program's safety, implementation process, and cost-effectiveness. Findings will determine if this approach should be expanded to more communities.
