Spatiotemporal Trends of Stroke Burden Attributable to Ambient PM _2.5 in 204 Countries and Territories, 1990–2019

Abstract

BACKGROUND AND OBJECTIVES: -related stroke burden by sex, age, and subtypes from 1990 to 2019 at global, regional, and national levels. METHODS: from 1990 to 2019. The Spearman correlation coefficient was used to examine the correlation between sociodemographic index (SDI) and EAPC of ASMR and ASDR at the national level. RESULTS: and the corresponding ASMR and ASDR were both in an increasing trend. The corresponding EAPCs in ASMR and ASDR were 0.09 (95% CI -0.05 to 0.24) and 0.31 (95% CI 0.18-0.44), respectively. The significant increases of ASMR and ASDR were observed in the low, low-middle, and middle SDI regions, and for ICH. However, a decreasing trend was observed in high and middle-high SDI regions, and for subarachnoid hemorrhage. DISCUSSION: are necessary to reduce the burden of stroke.
