[Burden of disease for stroke attributable to ambient PM_(2.5) exposure in China 1990-2019].

OBJECTIVE: To analyze the trend of disease burden of stroke attributable to ambient PM_(2.5) exposure among Chinese residents from 1990 to 2019. METHODS: On the basis of the data of global burden of disease study 2019(GBD 2019) in China, the burden of stroke attributable to the ambient PM_(2.5) exposure in China from 1990 to 2019 were analyzed using the number and rate of deaths, disability adjusted life year(DALY), DALY rate and its standardized rate and estimated annual percentage change(EAPC). RESULTS: In 2019, 24.7% of stroke deaths among people aged 15 years and above in China were due to ambient PM_(2.5) exposure. Compared with 1990, in China the number of stroke deaths and mortality attributable to ambient PM_(2.5) exposure increased to 541 800 and 39.08/100 000, respectively in 2019, and the attributable DALY and DALY rates increased by 2.07% and 1.56%, respectively, in 2019. And the attributable DALY and DALY in males were higher than those in females, and they were all increasing with aging. The attributed standardized mortality and DALY rates in China were higher than those of the global and different socio-demographic index(SDI) regions, and showed an increasing trend, with EAPCs of 1.11(95% CI 0.47-1.75) and 1.11(95% CI 0.53-1.69), respectively. CONCLUSION: The burden of stroke disease due to ambient PM_(2.5) exposure is heavy in China, with differences in gender and age, and is higher than those of the global and different SDI regions.
