Abstract:

Objective To analyze the distribution characteristics of occupational disease cases in Chenzhou City from 2005 to 2023 and provide a reference for occupational disease prevention and control. Methods Data on occupational disease cases in Chenzhou City from 2005 to 2023 were collected,and descriptive analysis were conducted on age at onset,length of employment,disease categories,regional distribution,industry sectors,and enterprise size. Results From 2005 to 2023,a total of 3 505 cases of occupational diseases were reported in Chenzhou City,covering 8 categories and 26 specific types,with an increasing trend followed by a decreasing trend. The top three types of occupational diseases were pneumoconiosis(3 087 cases,88.07%),occupational chemical poisoning(354 cases,10.10%),and occupational ear,nose,and throat(ENT) and oral diseases(45 cases,1.28%). The most common specific diseases were coal workers' pneumoconiosis,silicosis,arsenic and its compound poisoning,lead and its compound poisoning,and noise-induced deafness,totaling 3 329 cases(95.00%). Males accounted for the majority of cases(3 463,98.80%). Most patients were aged 41-<61 years(2 871 cases,81.91%),with a long average duration of occupational exposure[(16.41±8.57)years]. Geographically,cases were concentrated in Yongxing County(1 003 cases,28.62%),Jiahe County(767 cases,21.88%),and Yizhang County(660 cases,18.83%),totaling 2 430 cases(69.33%). There was a statistically significant difference in the composition of occupational diseases among counties,cities,and districts(P<0.05). While pneumoconiosis was the predominant type in most regions,Guiyang County had a higher proportion of occupational chemical poisoning. Occupational disease cases were primarily reported in small and medium-sized enterprises(2 767 cases,88.05%),with private and state-owned enterprises being the majority(2 546 cases,72.64%). The most affected industries were coal mining and nonferrous metal mining and processing(3 067 cases,87.50%),with key occupations being coal miners and tunneling workers. Conclusion It is necessary to strengthen the prevention and control of occupational diseases in key industries such as coal and non-ferrous metal mining,as well as small and medium-sized state-owned and private enterprises.
