ABSTRACT
Objective@#To analyze the prevalence of pneumoconiosis and civil aid and medical care among Xiangyang-Chongqing railway construction workers in Chongqing from 2011 to 2018, so as to provide scientific basis for prevention and control of pneumoconiosis.@*Methods@#The Chongqing database of Xiangyang-Chongqing railway construction workers cases from 2011 to 2018 were subjected to systematic collected. SPSS 18.0 was adopted for statistical description and analysis.@*Results@#From 2011 to 2018, a total of 7031 silicosis cases were diagnosed, and 5827 cases were existed, including 4056 cases of stage I, 1491 cases of stage II, and 280 cases of stage III. The cases were concentrated in the area along the southwest to northeast of Chongqing. The diagnosis age of silicosis patients was mainly 60~64 years old (69.73%) . Most silicosis cases were the drill workers and the stone workers. The exposure time of silicosis patients was short and concentrated in 3 years. The 5827 cases of pneumoconiosis in the Xiangyang-Chongqing railway were all treated with special civil aid and medical care for pneumoconiosis in the Xiangyang-Chongqing railway.@*Conclusion@#The prevalence of silicosis among workers who participated in Xiangyang-Chongqing railway construction remained serious. Civil aid and medical care covers all silicosis patients. Occupational health surveillance for silicosis and assistance should be carried out in these workers.
