Overview

Time-series study reveals increased cardiovascular hospital admissions linked to short-term temperature variability across urban populations, highlighting acute climate-related health risks.

Key Points

To evaluate short-term associations between daily temperature variability and hospital admissions for cause-specific cardiovascular diseases in urban China.
Conducted a national time-series analysis in 184 Chinese cities between 2014 and 2017 using the Urban Employee Basic Medical Insurance database covering 0.28 billion enrollees.
Calculated temperature variability from the standard deviation of daily minimum and maximum temperatures across 8.0 million cardiovascular disease admissions.
Analyzed city-specific associations using overdispersed Poisson models adjusted for temporal trends, holidays, mean temperature, and humidity, followed by random-effects meta-analyses.
A 1-°C increase in 0–1 day temperature variability was associated with increased hospital admissions for cardiovascular disease (0.44%, 95% CI: 0.32%–0.55%), ischemic heart disease (0.31%, 95% CI: 0.20%–0.43%), and heart failure (0.48%, 95% CI: 0.01%–0.96%).
Admissions also rose for heart rhythm disturbances by 0.34% (95% CI: 0.01%–0.67%) and ischemic stroke by 0.82% (95% CI: 0.59%–1.05%) per 1-°C increase.
Risk estimates decreased slightly but remained statistically significant after adjusting for ambient PM2.5, NO2, and SO2 air pollutants.
