About the study In the present study, researchers investigated the global burden of stroke due to non-optimal temperatures. They extracted data on stroke deaths and DALYs from the Global Burden of Diseases study by region, country, territory, sex, age, and sociodemographic index quintile between 1990 and 2019.
A decomposition analysis was undertaken to examine the factors driving changes in stroke burden over time. A fixed-effect panel data analysis was performed to analyze whether national-level indicators were associated with stroke burden attributable to non-optimal temperatures. Besides, SDI-related health inequalities in disease burden were explored.
Across SDI quintiles, stroke deaths, and DALYs showed a sharp increase since 1990, except in high-middle and high-SDI countries. Stroke mortality and DALY rates declined in all age groups, with the most significant reduction in the 0–4 age group. Every one-unit increment in PM2.5 and carbon dioxide emission increased ASMR by 0.16 and 0.15, respectively.
