Characteristics investigation and risk factors analysis of occupational benzene poisoning
Objective To investigate the characteristics and analyze the risk factors of occupational benzene poisoning in workers exposed to benzene series.Methods From January 2016 to January 2019,80 workers exposed to benzene series who were followed up to the disease control and prevention center were selected as the research objects,and their general data such as age,body mass index(BMI),gender,combined disease and smoking history were counted.The occurrence of occupational benzene poisoning among workers exposed to benzene series was analyzed;multivariate Logistic regression analysis was used to explore the risk factors of the occurrence of occupational benzene poisoning in workers exposed to benzene series.Results Among the 80 workers exposed to benzene series,20(25.00％)people who had occupational benzene poisoning were included in occurrence group;there were 60(75.00％)people who did not have occupational benzene poisoning were included in non-occurrence group.There were no significant differences in age,BMI,gender,combined disease,smoking history,alcoholism history,economic income and industry type between the two groups(P＞0.05);there were statistically significant differences in enterprise ownership,enterprise scale,post type,self-protection awareness and working limit of exposure to benzene series between the two groups(P＜0.05).Multivariate Logistic regression analysis showed that the enterprise ownership was private,the enterprise scale was small,the post type was benzene-related front-line staff,the self-protection awareness was weak,and the working limit of exposure to benzene series ≥10 years were the independent risk factors of the occurrence of occupational benzene poisoning in the workers exposed to benzene series(P＜0.05).Conclusion The enterprise ownership is private,the enterprise scale is small,the post type is benzene-related front-line staff,the self-protection awareness is weak,and the working limit of exposure to benzene series ≥ 10 years,which are the independent risk factors of the occurrence of occupational benzene poisoning in the workers ex-posed to benzene series.It should increase the attention of such workers exposed to benzene series and for-mulate effective interventions in a timely manner.
