Abstract

Higher air temperature and increased ambient ozone (O₃) concentration have been associated with childhood rhinitis risk. However, the potential mediating role of elevated O₃ in the increased childhood rhinitis risk due to higher air temperature exposure has not been examined. This large-scale cross-sectional study included 40,103 preschool children from 7 Chinese capital cities. Information on ever-rhinitis, current-rhinitis, and doctor-diagnosed allergic rhinitis (AR) was collected using a standardized questionnaire. Average air temperature (TEMavg) and O₃ concentration in the whole year, warm season, and cold season were estimated at 1 km spatial resolution. The findings revealed that exposure to higher air temperature (annual TEMavg, warm season TEMavg, and cold season TEMavg) and ambient O₃ (annual O₃, and warm season O₃) were associated with an elevated risk of ever-rhinitis, current-rhinitis, and doctor-diagnosed AR. Moreover, elevated O₃ concentration played important mediation effects on the relationships between higher air temperature and childhood rhinitis risk, with the mediated proportions ranging from 19.92% to 35.14% for the whole year, 18.62% to 32.82% for the warm season, and 3.85% to 13.32% for the cold season. Our study highlighted that controlling O₃ pollution may be an effective approach to mitigate the increasing childhood rhinitis risk due to global warming.

空气温度暴露与儿童鼻炎风险的关系及环境O3的中介作用：一项针对40,103名中国学龄前儿童的多城市研究

较高的气温和增加的环境臭氧（O3）浓度与儿童鼻炎的风险有关。然而，由于较高的空气温度暴露，O3升高在儿童鼻炎风险增加中的潜在介导作用尚未得到研究。这项大规模的横断面研究包括来自中国7个省会城市的40103名学龄前儿童。使用标准化问卷收集既往鼻炎、当前鼻炎和医生诊断的变应性鼻炎（AR）的信息。以1 km空间分辨率估算了全年、暖季和寒季的平均气温（TEMavg）和O3浓度。结果显示，较高的气温（年度、暖季和冷季TEMavg）和环境O3（年度、暖季O3）暴露与常年性鼻炎、现发性鼻炎和医生诊断的AR风险升高相关。此外，升高的O3浓度在较高气温与儿童鼻炎风险之间的关系中起重要的中介作用，中介比例为19.92% ~ 35.14%。暖季为18.62% ~ 32.82%，冷季为3.85% ~ 13.32%。我们的研究强调，控制臭氧污染可能是减轻全球变暖导致儿童鼻炎风险增加的有效途径。

期刊介绍： Sustainable Cities and Society (SCS) is an international journal that focuses on fundamental and applied research to promote environmentally sustainable and socially resilient cities. The journal welcomes cross-cutting, multi-disciplinary research in various areas, including: 1. Smart cities and resilient environments; 2. Alternative/clean energy sources, energy distribution, distributed energy generation, and energy demand reduction/management; 3. Monitoring and improving air quality in built environment and cities (e.g., healthy built environment and air quality management); 4. Energy efficient, low/zero carbon, and green buildings/communities; 5. Climate change mitigation and adaptation in urban environments; 6. Green infrastructure and BMPs; 7. Environmental Footprint accounting and management; 8. Urban agriculture and forestry; 9. ICT, smart grid and intelligent infrastructure; 10. Urban design/planning, regulations, legislation, certification, economics, and policy; 11. Social aspects, impacts and resiliency of cities; 12. Behavior monitoring, analysis and change within urban communities; 13. Health monitoring and improvement; 14. Nexus issues related to sustainable cities and societies; 15. Smart city governance; 16. Decision Support Systems for trade-off and uncertainty analysis for improved management of cities and society; 17. Big data, machine learning, and artificial intelligence applications and case studies; 18. Critical infrastructure protection, including security, privacy, forensics, and reliability issues of cyber-physical systems. 19. Water footprint reduction and urban water distribution, harvesting, treatment, reuse and management; 20. Waste reduction and recycling; 21. Wastewater collection, treatment and recycling; 22. Smart, clean and healthy transportation systems and infrastructure;
