Abstract: Objective To analyze the incidence of occupational pneumoconiosis in Xinzhou City from 2016 to 2022,and to explore the incidence and epidemiological characteristics of occupational pneumoconiosis in recent 7 years,so as to provide evidence for the prevention and control of occupational pneumoconiosis. Methods The basic information of occupational pneumoconiosis in Xinzhou City from 2016 to 2022,including the age,gender,region,disease type,course and stage,diagnosis age,age of exposure to dust were summarized. SPSS 26.0 was used for statistical analysis of the collected data. Results From 2016 to 2022,a total of 630 cases of occupational pneumoconiosis were reported in Xinzhou City,and the overall number of reported cases showed a decreasing trend. There were 609 new cases of occupational pneumoconiosis,accounting for 96.7%. Among occupational pneumo-coniosis,378 cases（60.0%） were diagnosed with stage Ⅰ pneumoconiosis. There were 104 cases（16.5%） of stage Ⅱ pneumoconiosis, 148 cases（23.5%） of stage Ⅲ pneumoconiosis. The majority of patients aged 50-<60 years were diagnosed,accounting for 43.7%. The number of dust exposure age 30-<40 years old was more,accounting for 31.7%. The main types of pneumoconiosis were silicosis and coal workers' pneumoconiosis,accounting for 99.2%. The number of workers in coal mining and washing industry accounted for 50.8%. There were statistically significant differences in the course and stage composition of the two major pneumoconiosis,the age of exposure to dust and the age of diagnosis of stage Ⅰ pneumoconiosis（all P<0.05）. The main types of work were rock drilling（147 cases）,coal mixing（118 cases）,other mining（103 cases） and other types of work,accounting for 74.8%. Among the regional distribution,the confirmed cases were more in Fanshi County,accounting for 29.0%. Conclusion Silicosis and coal workers' pneumoconiosis are the main occupational pneumoconiosis in Xinzhou City from 2016 to 2022,and there are differences in the pathogenesis characteristics of occupational pneumoconiosis. Occupational health examination should be conducted regularly for dust exposed workers in key industries and key types of work to reduce the incidence of occupational pneumoconiosis.
