BACKGROUND AND OBJECTIVES
The incidence of stroke among young adults was rising globally, but the death burden of stroke in young adults in China is lacking. We aimed to examine the temporal trends in mortality and years of life lost (YLLs) caused by stroke among young adults from 2005 to 2020 across China.
METHODS
Based on the data from the National Mortality Surveillance System in China, we estimated the number and age-standardized rate of mortality and YLLs due to stroke and its subtypes among young adults aged 15-49 years during 2005-2020, for both China and its 31 mainland provinces.
RESULTS
During 2005-2020, the age-standardized mortality rate of stroke among young adults aged 15-49 years in China decreased by 21.0%, from 5.9/100,000 to 4.7/100,000, and the YLL rate decreased from 286.9/100,000 to 229.5/100,000. The age-standardized mortality rate among young adults due to intracerebral hemorrhage (ICH) showed a significant downward trend with a decrease of 26.3% while that of ischemic stroke (IS) and subarachnoid hemorrhage (SAH) decreased by 4.5% and 0.6%, respectively. In 2020, the mortality rate of ICH was 3.5 times higher than that of IS (3.3/100,000 vs 0.9/100,000) among young adults in China. The male/female ratio of age-standardized mortality rate of stroke in young adults increased from 2.0 in 2005 to 3.1 in 2020. The age-standardized mortality rate of IS and SAH in young men increased by 11.0% and 2.5%, respectively. In 2020, Tibet (18.4/100,000), Jilin (10.4/100,000), and Qinghai (8.3/100,000) were the top 3 provinces holding the highest age-standardized mortality rate due to stroke among young adults. Tibet was found to have the highest mortality rate due to ICH and SAH while that of IS was higher in northeast China.
DISCUSSION
In China, the death burden caused by ICH among young adults was substantially higher than that of IS. The increasing death burden of IS and SAH among young men requires special attention. Evidence-based intervention strategies are needed to improve the outcomes of stroke and alleviate the death burden due to stroke among young adults in Chinese population.
