Analysis on current situation of occupational disease surveillance in Hedong District of Tianjin from 2020 to 2022

Abstract

Abstract: Objective To analyze the occupational health examination results of workers in Hedong District of Tianjin from 2020 to 2022,understand the health status of workers exposed to occupational hazards in Hedong District,and provide scientific basis for occupational disease prevention and control strategies in Hedong District. Methods Through national occupational diseases and occupational health information monitoring systems and Tianjin occupational diseases and health hazard factors monitoring systems,occupational health examination data and occupational disease diagnosis data of employees exposed to four occupational hazards of dust,benzene,noise,and high temperature in Hedong District from 2020 to 2022 were collected,and the distribution of new occupational diseases and occupational health examination situation in Hedong District were analyzed. Results From 2020 to 2022,there were 30,26,and 8 new cases of occupational diseases in Hedong District,showing a decreasing trend year by year. According to the occupational health examination results from 2020 to 2022,the abnormal rate of leukocyte in the benzene workers was the highest in 2021,and the difference was statistically significant（χ²=6.594,P<0.05）. The abnormal rate of white blood cells（χ²=33.139,P<0.05） and neutrophils in female workers exposed to benzene was higher than that in male workers（χ²=24.873,P<0.05）. The abnormal rate of double-ear high-frequency average hearing threshold ≥40 dB（A） in male workers exposed to noise was significantly higher than that in female workers（χ²=62.155,P<0.05）. There were statistically significant differences in the abnormal rates of blood glucose and blood pressure among workers exposed to high temperatures in different years,ages,and years of service. Conclusion Pneumoconiosis remains the most common occupational disease in Hedong District,followed by noise deafness. Attention should be paid to the sporadic occurrence of occupational diseases such as benzene poisoning and heatstroke.

Key words: Occupational disease, Harmful factors, Noise, High temperature
