Abstract

Urban heat island (UHI)-related mortality in different geographical regions remains controversial. In this study, we selected 70 pairs of adjacent urban-rural counties from 8 topographic regions in China. Daily mortality data from 2017 to 2021 were obtained from the mortality surveillance system of China. Daily temperature data were obtained from national meteorological stations located within the boundary of each county. A distributed lag nonlinear model and meta-regression were used to analyze the data. The results showed that the relationship between UHI and heat-related mortality varied across regions in China and could be classified into four categories. Regions with seldom and most frequent heat show lower urban-rural disparities in heat-related mortality. A higher heat risk was observed in urban than in rural areas in the Northeast Plain and Loess Plateau, with a moderate frequency of heat and low air conditioner ownership rate. Conversely, a negative correlation between UHI and mortality was observed in regions with frequent heat and high urban-rural disparity in the air conditioner ownership rate. Similar urban-rural disparities were found in older adults with specific causes. These findings contribute to a better understanding of the impacts of UHI on health and adaptive strategies.

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;
