Abstract: Objective To understand the morbidity trend of pneumoconiosis patients in Chongqing City and the current situation and influencing factors of the disease burden,and make recommendations to reduce the disease burden. Methods The number of pneumoconiosis cases from 2013 to 2022 was obtained through the "Occupational Disease and Health Hazard Surveillance Information System". The data on age,smoking,pneumoconiosis stage,disability level,complications and disease costs of 1 178 pneumoconiosis patients were obtained through the Chongqing pneumoconiosis disease burden survey project,and the data were analyzed. Results The overall trend of new pneumoconiosis in Chongqing City decreased year by year from 2013 to 2022. The average age of 1 178 pneumoconiosis patients was （56.9±8.05）years old,the median direct financial burden[M（P₂₅,P₇₅）] was 167.75（541.90, 5 263.31）yuan,the median indirect financial burden[M（P₂₅,P₇₅）] was 112 790.19（60 641.38,225 317.69）yuan,and the total person-years of disability adjusted life years（DALYs） was 8 892.03 years. DALYs were significantly higher in the 33-<50 year-old age group than in other age groups（P<0.05）. DALYs were significantly higher in Chengkou County than in the other two regions（P<0.05）. The lower the disability level,the higher the median DALYs（P<0.05）. DALYs were higher in patients with comorbidities than in those without comorbidities（P<0.05）. The age,pneumoconiosis stage,presence of comorbidities and disability grade were factors influencing the disease burden of pneumoconiosis. Conclusion The disease burden of pneumoconiosis in Chongqing is serious,and comprehensive measures should be taken to improve the current situation by strengthening dust hazard management,increasing pneumoconiosis pulmonary rehabilitation publicity and education,vigorously promoting the construction of rehabilitation stations,and adopting personalized rehabilitation measures.
