Objective: To analyze the distribution feature of occupational pneumoconiosis in Sichuan Province. Methods: The cases of newly diagnosed occupational pneumoconiosis from 2012 to 2021 in Sichuan Province were collected from the Occupational Diseases and Hazards Monitoring Information System under China Disease Prevention and Control Information System, and were analyzed retrospectively. Results: From 2012 to 2021, there were 30 136 newly diagnosed occupational pneumoconiosis cases in Sichuan Province. The average age of patients was 55.2 years and the median work age was 12.1 years. There were 6 471 cases (accounting for 21.5%) exposed to dust for less than 5.0 years. The number of the cases declined in newly diagnosed occupational pneumoconiosis and occupational pneumoconiosis with less than 5.0 years of dust exposure. The numbers of coal workers' pneumoconiosis and silicosis were 16 210 and 13 577, respectively (accounting for 98.9% of the total cases). The majority of pneumoconiosis cases were classified as stage Ⅰ(accounting for 67.1%). The cases from Leshan City, Bazhong City, Dazhou City, Yibin City, Guangyuan City and Luzhou City accounted for 68.8% of the total cases. The main types of work were coal miner and excavation worker, which accounted for 31.7% and 18.8%, respectively. The scale of enterprises was mostly small and micro, accounting for 35.1% of the cases, and the industry distribution was mostly coal mining and washing, accounting for 53.4% of the cases. Conclusion: In Sichuan Province, the number of cases shows an overall decline in both newly diagnosed occupational pneumoconiosis and occupational pneumoconiosis with less than 5.0 years of dust exposure, with a relatively short duration of occupational exposure. The key cities for pneumoconiosis prevention and control are Leshan City, Bazhong City, and Dazhou City, while the key industry is coal mining and washing.
