Abstract:
Objective:The epidemiological characteristics and trend of occupational pneumoconiosis in Hubei Province from 2011 to 2020 were analyzed to provide a theoretical basis for the development of prevention and control strategies for occupational pneumoconiosis.Methods:In March 2021, the data of newly occupational pneumoconiosis in Hubei Province from 2011 to 2020 were collected by the Occupational Diseases and Health Risk Factors Information Surveillance System. Descriptive statistics were adopted to analyze basic situation, region, industry, type of disease, year of diagnosis, age of onset and dust exposureduration of the cases.Results:From 2011 to 2020, a total of 7203 new cases of occupational pneumoconiosis were reported in Hubei Province, including 7125 (98.92%) men and 78 (1.08%) women. The average age of onset was (54.03±10.12) years old. The average duration of dust exposure was (13.80±9.56) years. The mainly types of pneumoconiosis were coal worker's pneumoconiosis (3593 cases, 49.88%) and silicosis (3301 cases, 45.83%). The cases included 4814 cases (66.83%) of stage Ⅰ pneumoconiosis, 1270 cases (17.63%) of stage Ⅱ and 1119 cases (15.54%) of stage Ⅲ. New cases mainly distributed in Yichang City (1586 cases, 22.02%), Shiyan City (1257 cases, 17.45%), Enshi Tujia and Miao Autonomous Prefecture (1050 cases, 14.58%) and Huangshi City (1009 cases, 14.01%), and occurred most frequently in coal mining and washing industry (3743 cases, 51.96%) and nonmetallic mining industry (582 cases, 8.08%). Pneumoconiosis patients of stage Ⅲ were mainly distributed in small enterprises (401 cases, 50.25%) and domestic enterprises (796 cases, 99.75%) .Conclusion:Coal worker's pneumoconiosis and silicosis accounted for the vast majority pneumoconiosis in Hubei Province. The new cases show obvious regions, industries and type of disease distribution. We should strengthen occupational health supervision in small and domestic enterprises.
