Summary

This cluster randomized trial is conducted in Beijing primary schools to evaluate the efficacy of a WeChat mini-program-based high-temperature early warning intervention on the physical and cognitive health of school-age children. Six participating schools are randomly assigned to two parallel groups. The intervention group receives tiered heat alerts and guided self-health monitoring via the mini-program. The control group follows standard daily school and family routines, with no dedicated digital high-temperature early-warning intervention. The primary outcome is children's executive function after a 2.5-month follow-up. A range of secondary indicators related to physical status, mental health and health behaviors are assessed concurrently to quantify the intervention's benefits in mitigating adverse health outcomes caused by high temperatures.

WeChat Mini-program Based Heat Health Risk Early Warning Intervention

This study implements a digital early warning intervention targeting children's high-temperature health risks. During the intervention period, when the high-temperature health risk level reaches yellow, orange or red, relevant risk information, health tips and heat protection education materials are released to parents and head teachers via the WeChat mini-program. Parents or teachers pass on the warning information to participating children. During non-summer periods, Beijing's high-temperature early warning information is pushed to head teachers and parents via the WeChat mini-program; during summer vacation, location-specific early warning information is sent to parents. All recipients are required to pass on the information to children promptly upon receipt.
