Objective To describe the patterns and characteristics of occupational diseases in Putuo District of Shanghai from 2000 to 2014, and provide a scientific basis for occupational disease prevention and treatment.
Methods A retrospective study was carried out among patients with diagnosed occupational diseases in Putuo District of Shanghai from 2000 to 2014. Disease categories, morbidity trend, and distributions status were analyzed.
Results There were 199 patients with occupational diseases newly diagnosed in Putuo District from 2000 to 2014. The cases appeared a declining trend in general with fluctuations. Occupational dermatosis, occupational chemical poisoning, and occupational ophthalmopathy were the largest proportional categories and accounted for 36.68%, 28.64%, and 18.09% of total cases respectively. Chemical skin burn, chemical eye burn, and occupational benzene poisoning were the leading three diseases with the highest incidence rates, accounting for 60.30% of total cases. More cases were reported in the 40-49-year age group and in the 1-9-year working age group than in the other groups. There were significant differences in average age of onset and average working age of onset among various occupational disease categories (F=8.47, P < 0.000 1; F=6.71, P < 0.000 1). The occupational disease cases were largely concentrated in chemistry material and product, pharmaceuticals, and general equipment manufacturing industries, accounting for 62.31% of all cases; especially, the occupational diseases reported in chemistry material and product manufacturing industry were predominant, which accounted for 37.19% of all cases. Ninety-two manufacturers reported occupational diseases, and a single pharmaceuticals manufacturing enterprise reported the largest proportion (23 cases). Moreover, 87.94% of the cases were reported from Taopu, Changzheng, and Changfeng communities.
Conclusion Occupational dermatosis, occupational chemical poisoning, and occupational ophthalmopathy are the predominant reported occupational diseases in the selected district. The prevention and control of occupational diseases should focus on chemical material and product manufacturing industry and pharmaceuticals manufacturing industry, as well as on those with shorter working age.
