Abstract: Objective To analyze the new cases of occupational pneumoconiosis in Jiangsu Province from 2006 to 2020,understand the incidence and distribution characteristics of pneumoconiosis in Jiangsu Province in recent years,and provide reference basis for further developing prevention and control strategies for pneumoconiosis. Methods The data of occupational pneumoconiosis network reports in Jiangsu Province from 2006 to 2020 were collected,and the data were analyzed. Results There were 9 914 new cases of occupational pneumoconiosis in Jiangsu Province from 2006 to 2020,with a sex ratio of 15.80：1. The first stage of pneumoconiosis was most common（81.95%）,the average age[M（P₂₅,P₇₅）] of onset was 60（52,67） years old,the of dust exposure age[M（P₂₅,P₇₅）] was 12（5,23） years,the age of onset was mainly distributed between 60-<70 years old（26.06%）,and dust exposure age was mainly <6 years（28.27%）. The number of diagnosed cases in 2009 was the largest（10.13%）,and the cases were mainly distributed in Wuxi City（22.37%）,Yancheng City（22.34%）,Suzhou City（16.38%） and Xuzhou City（14.61%）. The top three types of pneumoconiosis were silicosis（71.56%）,coal workers' pneumoconiosis（13.18%）,and welder's pneumoconiosis（7.99%）. The rock drilling was the most common type of work（31.10%）. The main complications of pneumoconiosis were pulmonary tuberculosis（0.37%） and lung and bronchial infection（0.21%）. For the economic type,the state-owned enterprises were the most（56.10%）,followed by collective enterprises（21.07%）. For the enterprise size,the small enterprises were the most（62.19%）,followed by large enterprises（24.79%）. The top three sectors with the highest distribution were health and social work（14.56%）,social affairs administration（14.10%）,and coal mining and washing（11.82%）. There were statistically significant differences in distribution of pneumoconiosis stages among cases in different economic type,enterprise size,age of onset,years of exposure to dust,work type and industry distribution（all P<0.05）. Conclusions The multi-dimensional distribution characteristics of occupational pneumoconiosis patients in Jiangsu Province from 2006 to 2020 are closely related to local industrial structure and enterprise characteristics. For jobs in high-risk industries,it is necessary to strengthen supervision,so as to eliminate the occupational hazard factors that workers exposed to dust may be exposed to and reduce the possible occupational disease risk.
