To analyze relevant data on the burden of appendicitis among individuals aged 70 and above in China from 1990 to 2019, describe its current status and epidemiological trends, and provide scientific evidence for exploring prevention and treatment strategies for appendicitis in the elderly population in China.
Utilizing the 2019 Global Burden of Disease data, this study analyzed the incidence, mortality, and disability-adjusted life years (DALY) of appendicitis in individuals aged 70 and above in China from 1990 to 2019. The Join point regression model was used to calculate the average annual percentage change (AAPC).
From 1990 to 2019, the incidence of appendicitis among individuals aged 70 and above in China exhibited a year-on-year increasing trend, with the most significant rise occurring between 2000 and 2005. In contrast, both the mortality rate and DALY rate showed a declining trend during the same period, with a substantial decrease starting in 2004. However, the decline rate has slowed down since 2008. Among different gender and age group compositions, the highest incidence was observed in the 70-74 age group, with a higher incidence in females compared to males. Conversely, the highest mortality and DALY rates were found in the 85-89 age group, with both rates being higher in males than in females.
Since 1990, the burden of mortality and DALY due to appendicitis among individuals aged 70 and above in China has gradually decreased, yet the incidence remains at a relatively high level. Therefore, it is essential for China to adopt various prevention and treatment strategies for the elderly population to reduce the disease burden of appendicitis in those aged 70 and above.
