[An analysis of disease burden of occupational lung cancer in China from 1990 to 2019].

Objective: To analyze the trend of disease burden, including mortality and disability-adjusted life years (DALYs) , of occupational lung cancer in China from 1990 to 2019. Methods: In June 2022, the data of occupational lung cancer was obtained from Global Burden of Disease Study 2019 (GBD) . Excel summarized the data, and the mortality rate, DALYs and age-normalized rate were analyzed. Applying Joinpoint Regression Program software annual Percentage Change (APC) and Average Annual Percentage Change Rate (AAPC) . Results: Age-standardized mortality rates ranged from 2.41 in 1990 to 3.14 per 100 000 in 2019, with gender differences and a positive correlation with age. DALYs increased from 580, 000 person-years in 1990 to 1 509 900 person-years in 2019. The rate of standardized DALYs increased from 63.03 per 100 000 in 1990 to 71.65 per 100 000 in 2019. According to the annual percentage change (APC) analysis by Joinpoint Regression Program software, the age-normalized mortality and DALY rates decreased from 2011 to 2016, and the increasing trend from 2016 to 2019 was significantly lower than that before 2011. And the increase at this stage was not statistically significant. The APCC values of mortality rate, standardized mortality rate, DALYs rate and changed DALYs rate were 3.28, 0.92, 2.64 and 0.44, respectively, and the trend differences were statistically significant. Conclusion: The disease burden of occupational lung cancer is increasing from 1990 to 2019. Lung cancer screening should be carried out among high-risk populations to achieve early diagnosis and treatment.
