Objective To understand the incidence and characteristics of occupational diseases reported in China from 2009 to 2018, and to provide evidence for the prevention and control measures of occupational diseases.
Methods The occupational disease incidence data were collected from the official website of the National Health Commission of the people's Republic of China in 2009 -2018. A retrospective analysis was made for the incidence of occupational diseases in 2009 -2018, and the differences of disease composition in different years were compared.
Results In 2009 -2018, 270 254 cases of occupational diseases were diagnosed in China, including 235 553 cases (87.16%) of pneumoconiosis and other respiratory diseases, 15 589 cases (5.77%) of chemical poisoning, 9 047 cases (3.35%) of occupational otolaryngological and stomatological diseases, 3 883 cases (1.44%) of occupational infections, 2 232 cases (0.83%) of occupational diseases caused by physical factors, 132 cases (0.49%) of occupational skin diseases, 1 258 cases (0.47%) of occupational eye diseases, 870 cases (0.32%) of occupational tumors, 143 cases (0.05%) of occupational radioactive diseases and 359 cases (0.13%) of other occupational diseases. In all kinds of occupational diseases, the incidence of pneumoconiosis and other respiratory diseases and occupational tumors was in a state of dynamic equilibrium, with no obvious increase or decrease trend. The incidence of occupational diseases and infectious diseases caused by oral diseases, physical factors, and infectious diseases showed an increasing trend, and a decreasing trend for chemical poisoning, occupational skin diseases, occupational eye diseases, and occupational radiation diseases.
Conclusion Pneumoconiosis and other respiratory diseases were the most important occupational diseases in China, and occupational exposure to chemicals was a major hazard. Occupational diseases with an increasing incidence of otolaryngology and oral diseases need to be strengthened for prevention and control.
