Heat waves represent an emerging climate-related health threat, yet inequalities in kidney mortality attributable to heat waves and their association with hospital accessibility remain insufficiently characterized. As climate change intensifies, understanding these disparities is essential to inform adaptive healthcare planning and protect vulnerable populations.
This nationwide study analyzed kidney mortality among adults aged 60 years and older using data from China’s national mortality surveillance in 2021, covering both urban and rural populations. Heat wave exposure was assessed using a high-resolution grid-based model at 1 km resolution. We estimated kidney deaths and attributable mortality rates (AMRs) linked to heat waves and evaluated inequalities in hospital accessibility using attributable death–weighted Gini indices and Lorenz curves. Future projections of kidney mortality burden were generated under four Shared Socioeconomic Pathway scenarios (SSP1–2.6, SSP2–4.5, SSP3–7.0, SSP5–8.5).
In 2021, approximately 0.49 percent (0.23–0.71 percent) of all kidney deaths among older adults were attributable to heat waves nationwide. The national AMR reached 0.13 per 100000 (0.06–0.18), with higher values observed in rural areas, temperate continental zones, and Central and Western regions. Both the number of attributable deaths and the AMR increased with advancing age and were consistently higher in men than in women. The national average driving time to the nearest hospital was 16.7 minutes, but accessibility was substantially poorer in rural areas, alpine highland zones, and Western regions. The attributable death–weighted Gini index for hospital accessibility reached 0.46, indicating marked inequality. Projections suggested that the burden attributable to heat waves may increase more than four-fold by the end of the century, particularly under high-emission scenarios (SSP3–7.0 and SSP5–8.5).
Significant regional and demographic inequalities exist between the kidney mortality burden attributable to heat waves and hospital accessibility in China. Rural and Western areas face both higher mortality and poorer access to healthcare. Climate change is expected to exacerbate these disparities, leading to a widening gap in health outcomes. Targeted strategies that strengthen hospital infrastructure, improve early warning systems, and enhance healthcare accessibility in high-risk regions are urgently needed to build resilience against future climate-related kidney disease burden.
