Quantifying localized heatwave impact on mortality: a multi-country modeling study in the Asia-Pacific region.

ABSTRACT:

Background

Heatwave is a global health threat. However, existing heatwave definitions often rely on fixed temperature thresholds without incorporating region-specific health outcomes or population acclimatization, limiting their applicability across diverse climatic and demographic contexts. We aimed to assess the impact of localized heatwave on mortality based on a proposed framework of health-based heatwave definition.

Methods

Based on daily data on death and weather from 25 cities in Australia, China, South Korea, and Thailand, we proposed a health-based excess heat factor (HEHF) to define the localized heatwave. First, a tiered health risk-based (THR) approach was used to fit the heatwave-mortality association to detect the region-specific temperature threshold for heatw
