Abstract:
Objective:To analyze the distribution characteristics of new pneumoconiosis in different industries in Tianjin from 2009 to 2018, in order to provide a theoretical basis for the prevention and treatment of pneumoconiosis.Methods:In November 2019, the data of new pneumoconiosis cases in Tianjin from 2009 to 2018 were collected and classified according to difference industries. The epidemiological characteristics of new pneumoconiosis in different industries were analyzed based on time, type of pneumoconiosis, type of work, age, and working age.Results:A total of 4657 new cases of pneumoconiosis were reported in Tianjin from 2009 to 2018, 4640 cases (99.63%) in the first stage, 13 cases (0.28%) in the second stage, and 4 case (0.09%) in the third stage. The number of new cases increased with time and then decreased. Among them, there were 3482 males (74.77%) and 1175 females (25.23%) . The proportion of women with new pneumoconiosis in the non-metallic mineral products industry was the highest, and the differences were statistically significant ( P<0.05) . There are differences in the distribution of new pneumoconiosis species in different industries (χ 2=4920.11, P<0.05) . Silicosis is mainly distributed in non-metallic mineral products industry, metal smelting and rolling processing industry, petroleum processing coking and nuclear fuel processing industries. Foundry worker′s pneumoconiosis is mainly distributed in the general equipment manufacturing industry and special equipment manufacturing industry, and cement pneumoconiosis is mainly distributed in the non-metallic mineral products industry. The types of work are mainly distributed in smelting, casting, raw materials and forming workers, and the sum of the three accounts for 36.46% (1689/4657) . The M ( P25, P75) of diagnosis age was 56.0 (50.0, 63.0) years, and the M ( P25, P75) of working age was 19.0 (16.0, 26.0) years. The working age of new pneumoconiosis patients in the petroleum processing, coking and nuclear fuel processing industries is 19.0 (16.0, 26.0) years, which is shorter than that of other industries ( P<0.05) ; The diagnostic age of the general equipment manufacturing industry is 54.0 (49.0, 59.0) years, which is less than that of other industries ( P<0.05) . New pneumoconiosis is mainly distributed in large and medium-sized enterprises. New cases of pneumoconiosis in non-metallic mineral products industry, metal smelting, calendar processing industry and general equipment manufacturing industry are mainly distributed in large and medium-sized enterprises. New cases of pneumoconiosis in the metal products industry, special equipment manufacturing industry and petroleum processing, coking and nuclear fuel processing industries are mainly distributed in large enterprises. Conclusion:The work of preventing and controlling pneumoconiosis in Tianjin has a long way to go. We should implement targeted measures according to the characteristics of pneumoconiosis industry, strengthen the supervision of hazard industries, and effectively control the occurrence of pneumoconiosis.
