Objective To analyze the epidemiological patterns and characteristics of occupational diseases occurrence in Qingpu District of Shanghai in 2002-2013,and to provide a scientific basis for occupational diseases prevention and control.
Methods Verification and statistical analysis were performed on the data of occupational diseases retrieved from the mandatory occupational disease report cards in Qingpu from 2002 to 2013.
Results A total of 404 cases of occupational diseases were newly diagnosed and reported in 2002-2013.The age was ranged from 18 to 79 years,and the mean age was (38.69& #177;13.60) years.The ratio of male (317) to female (87) cases was 3.64:1.Occupational dermatology (148,36.63%),pneumoconiosis (102,25.25%),and occupational poisonings (81,20.05%) were the leading three occupational diseases.The median of exposure age of occupational dermatology was 1.33 years;the average exposure age of pneumoconiosis and occupational poising were (11.44& #177;6.38) and (5.92& #177;4.55) years,respectively.Aluminum pneumoconiosis (55.88%),electric arc welder pneumoconiosis (13.73%),foundry worker pneumoconiosis (10.78%),and silicosis (8.82%) were the leading four pneumoconiosis incidences.In terms of occupational poisonings,hydrogen sulfide poisoning (13/48) ranked the first place of acute occupational poisonings,and chronic benzene poisoning ranked the first of chronic occupational poisonings (32/33).Chemical industry (87 cases),building material industry (86 cases),light industry (81 cases),and machinery industry (77 cases) were the leading four industries that occupational diseases occurred.Reported occupational disease patients concentrated in private sectors (170) and township collective enterprises (80) regarding enterprise economic category,as well as in small enterprises (316) regarding enterprise size.
Conclusion The reported occupational disease cases in Qingpu demonstrate trends of younger onset and shorter exposure history.Occupational dermatology,pneumoconiosis,and occupational poisonings are locally prioritized occupational diseases.Hydrogen sulfide,benzene and benzene homologue,welding fume,foundry dust,and silicon related dust are the main occupational hazards in Qingpu District.Efforts should be made to focus on occupational health supervision and occupational technical guidance in small and micro enterprises.
