Abstract:

Objective To understand the incidence characteristics of newly reported occupational pneumoconiosis in Hanzhong City from 2017 to 2024,and provide scientific basis for the prevention,control and supervision of occupational pneumoconiosis. Methods Collect data on occupational disease cases diagnosed by occupational disease diagnosis institutions in Hanzhong City from 2017 to 2024,with a focus on summarizing and analyzing the reporting time,pneumoconiosis type,pneumoconiosis period,dust-exposed working years,gender,age,location,type of enterprise,and distribution of enterprise scale. Results From 2017 to 2024,91 new cases of occupational pneumoconiosis were reported in Hanzhong City,primarily silicosis(73 cases,80.22%) and coal worker's pneumoconiosis(18 cases,19.78%). Stage Ⅰ pneumoconiosis was the most common(41 cases,45.05%),followed by stage Ⅱ pneumoconiosis(34 cases,37.36%),with stage Ⅲ pneumoconiosis being the least frequent(16 cases,17.58%). There was a statistically significant difference in the distribution of stages between silicosis and coal worker's pneumoconiosis(χ2=7.029,P<0.05),with the proportion of stage Ⅲ being significantly higher in coal worker's pneumoconiosis than in silicosis. All cases were male,and the age of onset was mainly 40-<60 years old(86 cases,94.51%). The most common incidence of the disease occurred within 5-<10 years of exposure to dust(33 cases,36.26%),followed by 2-<5 years(24 cases,26.37%). Silicosis was mainly distributed in Lueyang County(68.49%),while coal worker pneumoconiosis was mainly concentrated in Zhenba County(94.44%). The industry was mainly concentrated in the mining industry(84 cases,92.31%),with private enterprises as the main economic type(84 cases,92.30%),and small enterprises being the largest in terms of enterprise size(78 cases,85.71%). There were statistically significant differences in the comparison of different pneumoconiosis diseases with different work experience groups,regions,and economic types of enterprises(all P<0.05). There were statistically significant differences in the composition ratio of pneumoconiosis stage Ⅲ with various counties and districts,and economic types of enterprises(both P<0.05). Conclusion The main types of occupational pneumoconiosis in Hanzhong City are silicosis and coal worker pneumoconiosis,and there are differences in the incidence characteristics of occupational pneumoconiosis. Lueyang County and Zhenba County should be listed as key areas,with mining industry as the key industry and small and private enterprises as the key enterprises. Relevant departments should implement the main responsibility of enterprises,carry out targeted governance work,and reduce the incidence of occupational pneumoconiosis.
