Study on Intervention Effect of Heat-related Health Risk Early Warning Digital Technology for School-age Children
2026年6月9日 更新者：Tiantian Li、Centers for Disease Control and Prevention, China
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.

詳細な説明
This pilot study is conducted in Beijing, with 6 primary schools selected as research sites. A stratified cluster randomized controlled design is adopted, with schools as the unit of randomization. Eligible primary schools are randomly assigned to the intervention group and the control group, with 3 schools in each group.
A total of 5 Wisconsin Card Sorting Tests (WCST), 2 health examinations, 2 children's high-temperature protection themed drawing activities, and 5 mini-program questionnaire surveys will be conducted in this study.
The intervention group receives a digital intervention of high-temperature health risk early warning. The research team uses a WeChat mini-program to release corresponding high-temperature health risk level information, health tips, protection science popularization information and other early warning content when the high-temperature health risk level reaches yellow, orange or red, and simultaneously pushes them to head teachers and parents.
The monitoring and survey schedule for the intervention group during the study period is as follows: at baseline and endpoint, unified offline WCST and health examinations will be conducted for children once each, accompanied by one online mini-program questionnaire survey each time. One children's high-temperature protection themed drawing activity will be organized at baseline and at the end of the 3rd month after the intervention, and the works will be uploaded to the mini-program for check-in. At the end of the 1st, 2nd and 3rd months after the intervention, one online follow-up questionnaire and WCST will be completed each month, together with check-in. Meanwhile, blood pressure will be monitored once a week, and daily blood pressure monitoring and check-in will be carried out after each high-temperature health risk early warning release. In addition, after the release of high-temperature health risk early warnings, the intervention group is required to complete check-in for reading and transmitting early warning information, health tips and protection science popularization content, as well as online mini-program surveys on children's awareness of high-temperature health risk early warning information and short-term behavioral patterns. The above WCST and questionnaire surveys will be completed by children with parental assistance; blood pressure monitoring and check-in are the responsibility of head teachers during non-summer vacations and parents during summer vacations.
The control group does not receive the high-temperature health risk early warning intervention and will only complete the corresponding WCST, health examinations, questionnaire surveys and blood pressure monitoring.

実験的：WeChat Mini-program Heat Health Early Warning Intervention Group
Participants receive tiered yellow, orange and red heat risk alerts and heat protection guidance via the WeChat Mini Program once alerts are issued due to high temperatures.
Teachers and parents share health promotion tips with enrolled children.
Mandatory mini-program check-ins and routine health monitoring are implemented throughout the 2.5-month 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.

|
The primary outcome is the comprehensive total score of children's executive function constructed based on the Wisconsin Card Sorting Test (WCST)
時間枠：at 2.5 months of intervention.
|
The only primary outcome of this study is the composite score of cognitive executive function derived from the Wisconsin Card Sorting Test (WCST) via the TOPSIS method.
All WCST absolute indicators and sub-dimensions are sub-indicators instead of independent outcomes.
The WCST indicators are grouped into three sub-dimensions: conceptual thinking (Total Correct, Total Errors, Nonperseverative Errors, Conceptual Level Responses, Categories Completed), perseveration (Perseverative Responses, Perseverative Errors), and set maintenance (Failure to Maintain Set).
Negative indicators are converted using the formula (x' = Max(x) - x).
After Z-score normalization, the decision matrix is established, positive and negative ideal solutions are identified, and Euclidean distances and relative closeness are computed.
The resulting relative closeness value is taken as the final composite score of cognitive executive function, the single primary outcome of this study.
