Projected extreme temperature event-attributable dementia deaths in China: a climate-ageing-adaptation framework.

ABSTRACT:

Background

Climate change is increasing health risks worldwide, but how extreme temperature events affect Alzheimer's disease and other dementias (ADD) remains poorly understood. We aimed to project future extreme temperature event-attributable ADD deaths in China, accounting for the combined effects of climate change, population ageing, and adaptation methods.

Methods

We analysed 399,036 ADD deaths among adults aged ≥60 years in China during 2013-2020, using a time-stratified case-crossover design to estimate ADD mortality risks associated with extreme temperature events. We subsequently developed an integrated climate-ageing-adaptation framework that combined exposure-response functions, high-resolution climate projections, and demographic forecasts. Using this framework,
