Overview

Longitudinal analysis reveals how heatwaves, pollution, and green space influence mortality in older adults with diabetes, suggesting critical public health interventions.

Key Points

This study examines how heatwaves, air pollution, and green space affect all-cause mortality in older adults with diabetes.
Longitudinal analysis of 1,400 adults aged ≥ 45 with diabetes from CHARLS (2011-2020).
Defined heatwaves by intensity-duration thresholds based on maximum temperatures.
Used time-varying Cox proportional hazards models to estimate hazard ratios while adjusting for air pollutants and greenness.
Increased HR from 1.027 (95% CI: 1.013-1.041) to 1.070 (95% CI: 1.048-1.093) with intensifying heatwaves.
Significant synergistic effects observed between heatwaves, air pollution, and reduced green space.
Effects were more pronounced in older individuals and urban residents.
