ABSTRACT
Objective To understand the epidemiological characteristics of pneumoconiosis through analyzing the data of pneumoconiosis cases in Liuzhou from 2006 to 2018, and to provide a scientific basis for the prevention and control of pneumoconiosis in Liuzhou. Methods The information of pneumoconiosis cases in Liuzhou was collected through the “health hazard factors monitoring information system”, a subsystem of China's disease prevention and control system, and the epidemiological characteristics of pneumoconiosis were statistically analyzed by descriptive statistics. Results A total of 160 cases of pneumoconiosis was collected, mainly stage I silicosis, accounting for 70.0% of total cases (n=112). Most of the cases were from the metal smelting and rolling industry, accounting for 82.5% of total cases (n=132). The occupation of patients was mainly smelting and auxiliary work, sintering, and mining, accounting for 23.13% (n=37), 27.50% (n=44) and 18.13% (n=29) of the total number of pneumoconiosis cases, respectively. Among them, 83.75% (n=134) were from large-scale enterprises. Most of the pneumoconiosis cases had 15 to 35 years of dust exposure, with an average dust exposure of 23.78±10.36 years. The age of onset was mainly concentrated in 45 to 60 years old, and the average age of onset was 55.61±10.28 years. Conclusion The cases of pneumoconiosis in Liuzhou existed in sporadic form in recent years, and the cases were mainly concentrated in large metal smelting enterprises, with smelting and auxiliary workers and sintering workers being the most serious. It is necessary to strengthen the occupational health management of large metal smelting enterprises to effectively prevent and control the occurrence of pneumoconiosis.
