[Epidemiological characteristics of pneumoconiosis in Gansu Province from 2010 to 2018].

Abstract

Objective: The epidemiological characteristics of occupational pneumoconiosis in Gansu Province from 2010 to 2018 were analyzed to provide a theoretical basis for the development of prevention and control strategies for pneumoconiosis in Gansu Province. Methods: In March 2019, the data of newly diagnosed occupational pneumoconiosis in 2010-2018 and the data of occupational pneumoconiosis as of December 31, 2018 in Gansu Province were collected by the Occupational Disease and Occupational Health Information Monitoring System. The stage, type of disease, time, enterprise information of newly diagnosed pneumoconiosis and the region, type of disease, enterprise information of existed pneumoconiosis were analyzed. Results: From 2010 to 2018, a total of 1269 new cases of occupational pneumoconiosis were reported in Gansu Province, including 818 cases (64.46%) of stage I pneumoconiosis, 284 cases (22.38%) of stage II pneumoconiosis, 167 cases (13.16%) of stage III pneumoconiosis. Silicosis, coal worker's pneumoconiosis and cement pneumoconiosis ranks the top 3, accounting for 55.71% (707/1269) , 37.67% (478/1269) and 3.78% (48/1269) of the total number, respectively. The new cases of stage III pneumoconiosis were mainly distributed in private economy (58.09%, 79/136) and small-sized (59.88%, 97/162) enterprises. As of December 31, 2018, Gansu Province had reported a total of 12211 cases of occupational pneumoconiosis, of which 58.16% (7102/12211) were coal worker's pneumoconiosis and 28.15% (3438/12211) were silicosis. Mainly distributed in Baiyin city (21.63%, 2641/12211) , Lanzhou city (17.79%, 2172/12211) and Wuwei city (13.73%, 1676/12211) . The existed cases of pneumoconiosis are mainly distributed in state-owned economy (76.95%, 9396/12211) and large-sized (54.23%, 6622/12211) enterprises. Conclusion: Silicosis and coal worker's pneumoconiosis are the main type of pneumoconiosis in Gansu Province. And the number of silicosis reported is on the rise, which should be taken seriously. Pneumoconiosis in Gansu Province is mainly distributed in state-owned economy and large-sized enterprises. However, pneumoconiosis patients in private economy and small-sized enterprise is generally serious, so it should be the focus of supervision.
