Abstract: Objective To analyze the characteristics of new pneumoconiosis cases in a district of Beijing from 2014 to 2023. Methods The newly diagnosed and reported pneumoconiosis cases from 2014 to 2023 were collected and analyzed through the“China Disease Prevention and Control Information System" subsystem "Occupational Disease and Health Hazard Monitoring Information System". Results A total of 114 new pneumoconiosis cases were reported in a certain district of Beijing from 2014 to 2023,mainly silicosis(69.3%),and the number of stage I pneumoconiosis cases was the highest(82 cases,71.93%). The average age of diagnosis for the cases was (61.48±11.75)years,and the average length of dust exposure was (21.71±10.04)years. The cases were mainly concentrated in the mining industry(77 cases,67.54%) and large enterprises(98 cases,85.96%),and the main types of work were crushing and other types of work in the factory. There were statistically significant differences in disease types of pneumoconiosis among different diagnosis age,dust exposure age,industry and enterprise scale(all P<0.05). There were statistically significant differences in the age of diagnosis and the length of dust exposure among different genders,types of pneumoconiosis,starting date of exposure,types of work and industry types(all P<0.05). Conclusion From 2014 to 2023,the overall incidence of new occupational diseases in a certain district of Beijing showed a downward trend,with a high proportion of pneumoconiosis cases. It is necessary to continue to strengthen the prevention and control of occupational diseases and protect the health rights and interests of workers.
