Analysis on status of new occupational diseases cases in Xuzhou City from 2009 to 2022
Objective To understand the distribution of new occupational disease cases in Xuzhou City,compare the age of onset and the duration exposure to dust among different types of pneumoconiosis,and provide reference for the prevention and treatment of occupational diseases and their early prevention.Methods Collect the newly diagnosed and reported cases of occupational diseases from 2009 to 2022 in the surveillance information system of occupational diseases and health hazards,and conduct descriptive analysis on the incidence of occupational diseases.Results A total of 1 265 new cases of occupational diseases were reported in Xuzhou City,including 1 126 cases of pneumoconiosis(89.01％),36 cases of occupational ophthalmopathy(2.85％)and 35 cases of occupational otorhinolaryngological and oral diseases(2.77％).The industry category of the enterprises to which the cases belong was mainly mining industry(67.11％).There were a total of 1 126 cases of 12 kinds of new diagnosed pneumoconiosis,among which coal worker's pneumoconiosis and silicosis were the main types(95.12％).With the increase of the age of onset and the duration exposure to dust,the overall number of new cases of pneumoconiosis was on the rise.The age group of 50-＜60 years old had the highest number of new cases(363 cases,32.38％),while the age group of 20-＜30 years of the duration exposure to dust had the highest number of cases(374 cases,33.36％).The onset age of newly diagnosed cases of pneumoconiosis[M(P25,P75)]was 55.67(49.61,68.10)years old,and the working experience of dust exposure[M(P25,P75)]was 24.00(11.88,30.25)years.Among them,the age of onset of silicosis was the oldest at 59.32(51.93,65.99)years,and the working years of coal worker's pneumoconiosis was the longest at 27.08(20.00,31.00)years.There were statistically significant differences in the incidence age and working years exposure to dust among coal worker's pneumoconiosis,silicosis and welder pneumoconiosis(all P＜0.01).There were 10 cases of coal worker's pneumoconiosis and 87 cases of silicosis among the pneumoconiosis patients(mainly railroad soldiers and rock drillers)who exposed to dust less than 5 years.Conclusion The new occupational diseases in Xuzhou City are mainly pneumoconiosis,mainly the coal workers'pneumoconiosis and silicosis.The prevention and treatment of pneumoconiosis is still one of the key occupational health work in the city.
