To explore the impact of extreme temperature on the risk of non-accidental mortality in Zhangjiakou city, and to identify susceptible subpopulations.
Data on non-accidental mortality among residents in Zhangjiakou City from 2019 to 2024, as well as concurrent meteorological and air pollution data, were obtained from the Air Pollution and Health Effects Monitoring Information System. The distributed lag non-linear model (DLNM) was employed to analyze the exposure-lag-response relationships between extreme temperatures and both non-accidental mortality and cardiovascular disease mortality, with stratified analyses conducted by sex and age group.
The exposure-response relationship between daily mean temperature and both non-accidental and cardiovascular mortality exhibited a U-shaped curve. The effects of extreme cold showed persistent lag patterns, with the cumulative relative risks (cumulative RRs) peaking at lag 21 days for both non-accidental mortality (CRR=2.470, 95%CI: 1.746-3.494) and cardiovascular mortality (CRR=2.163, 95%CI: 1.379-3.394). In contrast, the effects of extreme heat were acute and short-lived, with cumulative RRs peaking at lag 6 days (CRR=1.483, 95%CI: 1.316-1.672) and lag 5 days (CRR=1.462, 95%CI: 1.236-1.729) for non-accidental and cardiovascular mortality, respectively. Stratified analysis revealed that males and individuals aged ≥65 years were at higher risk, with greater cumulative RRs during extreme temperature events.
Extreme temperatures significantly increase the risk of cardiovascular mortality in Zhangjiakou. Males and the elderly (≥65 years) are particularly vulnerable.
