[Purpose] To analyze the disease burden of malignant tumors and its changing trends in Chinese and global non-smoking female population from 1990 to 2021. [Methods] Data of mortality and disability adjusted life year (DALY) for Chinese and global non-smoking female malignant tumors from 1990 to 2021 were extracted from the Global Burden of Disease Study 2021 (GBD 2021), and the data were analyzed using Joinpoint regression model to calculate the average annual percentage change (AAPC). [Results] From 1990 to 2021, the number of deaths for malignant tumors in Chinese non-smoking female population increased from 13.71×104 to 26.81×104, with a higher increased trend compared with the global (China: AAPC = 2.19%, 95% CI: 2.06%~2.33%; Global: AAPC = 1.92%, 95% CI: 1.80%~2.04%; P = 0.003); the standardized mortality rate decreased from 32.42/105 to 24.58/105, with a higher decreased trend compared with the global (China: AAPC = -0.88%, 95% CI: -1.00%~-0.76%; Global: AAPC = -0.59%, 95% CI: -0.68%~-0.51%; P < 0.001). The DALY for malignant tumors in China increased from 412.96×104 to 691.20×104 person-years, with a similar changing trend compared with the global (China: AAPC = 1.68%, 95% CI: 1.56%~1.81%; Global: AAPC = 1.63%, 95% CI: 1.52%~1.75%; P = 0.536); the standardized DALY rate decreased from 889.58/105 to 642.65/105, with a higher decreased trend compared with the global (China: AAPC = -1.04%, 95% CI: -1.15%~-0.92%; Global: AAPC = -0.69%, 95% CI: -0.78%~-0.61%; P < 0.001). The top five malignant tumors of high standardized mortality rate in China in 2021 were tracheal, bronchus and lung cancer, colon and rectum cancer, cervical cancer, breast cancer, and liver cancer. The top five malignant tumors of high standardized mortality rate globally in 2021 were cervical cancer, colon and rectum cancer, breast cancer, tracheal, bronchus and lung cancer, and pancreatic cancer. The standardized mortality rate and DALY rate of breast cancer, liver cancer, pancreatic cancer and uterine cancer showed overall upward trends (all P<0.05). [Conclusion] From 1990 to 2021, the number of deaths and DALY of malignant tumors in Chinese and global non-smoking female population showed overall increased trends, and standardized mortality rate and DALY rate showed overall decreased trends. In future, more targeted cancer prevention measures are needed to reduce the disease burden of malignant tumors in non-smoking female population. |
