Objective To provide reference for the formulation of public health policies through exploring the disease burden of aortic aneurysm (AA) in young adults. Methods Following the general analytical strategies used in the Global Burden of Disease (GBD) study 2019, we analyzed sex-specific mortality rates and years of life lost (YLLs) among young adults AA in China from 1990 to 2019, compared with global and sociodemographic index(SDI) stratified of young adults AA. Joinpoint was used to analyze the time trend of AA burden among young adults men and women in China. To analyze the attributable risk factors of AA burden in young adults and explore its characteristics. Results Among young adults (15-39 years old) in China, the total of AA deaths in 2019 was 657 (95%UI 549-791), an increase of 16.9% compared with 1990. The mortality rate in 2019 was 0.13 per 100 000 person-years (95%UI 0.11-0.16), an increase of 30%. In 2019, a total of 36921 (95%UI 30 865-44 445) YLLs were produced by young adults in China, an increase of 13.21% compared with 1990. The YLLs rate was 7.42 per 100 000 person-years (95%UI 6.2-8.93), an increase of 24.92%. The male YLLs rate was 11.49 per 100 000 population years (95%UI 9.22-14.28), increasing by 35.18%; The female YLLs rate was 3.11 per 100 000 person-years (95%UI 2.36-3.98), a decrease of 3.12%. Both the AA mortality rate and YLLS in male young adults were higher than those in female, and the growth rate from 1990 to 2019 was significantly higher than that in female. Conclusion The disease burden of AA among young adults in China increased significantly from 1990 to 2019, mainly among males. The time trend of male and female AA YLLs in Chinese young adults was obviously inconsistent. The AA YLLs of Chinese male young adults were positively correlated with economic development and the progress of medical technology, and were in the process of gradual increase. The AA YLLs of Chinese female young adults were much lower than the average level, which was closely related to the low smoking rate.
