Chronic kidney disease burden attributable to heat waves amid climate change and related hospital accessibility: a health impact assessment study based on two nationally representative surveys in China.

ABSTRACT:

Background

Heat waves are increasingly recognized as an environmental determinant of chronic kidney disease (CKD). However, the CKD burden attributable to heat waves and associated healthcare inequalities, particularly under future climate change, remains insufficiently characterized.

Methods

Based on two nationally representative cross-sectional surveys in China, we established climate region-specific exposure-response functions between heat waves and CKD. Then, we conducted 1-km grid-level health impact assessments integrating the most up-to-date nationally representative CKD prevalence data, temperature projections, population estimates, and socioeconomic indicators. The analyses focused on stages 4-5 CKD (advanced CKD), given its progressive nature and requirements for c
