Analysis of abnormal blood routine and influencing factors among workers exposed to benzene in Sichuan Province from 2020 to 2022
Objective To analyze the blood routine in occupational health examination of workers exposed to benzene in Sichuan Province and its influencing factors,and to provide basis for prevention and control of occupational hazard caused by benzene.Methods Occupational health examination data of all on-job and off-job workers exposed to benzene in Sichuan Province from 2020 to 2022 were collected from the Comprehensive Management Information System for Occupational Disease Prevention and Control in Sichuan Province and the Occupational Disease and Health Hazard Factor Monitoring Information System of Chinese Center for Disease Control and Prevention.SPSS 26.0 software was used to analyze the results of blood routine examination and influencing factors.Pearson x2 test was used for inter-group comparison.Binary Logistic regression was used for influencing factor analysis,and the test level was α=0.05.Results Among 81420 benzene exposed workers,4399 had abnormal blood routine,with a detection rate of 5.45％.The detection rate in women(7.36％)was higher than that in men(4.37％),and the difference was statistically significant(x2=326.494,P＜0.001).The abnormal blood routine rate gradually increased with the increase of age(x2trend=77.461,P＜0.001).The results of multivariate Logistic regression analysis showed that female,older age,shorter working experience and small or micro enterprise scale were the risk factors for abnormal blood routine of benzene exposed workers(all P＜0.05).Conclusions The benzene exposure base in Sichuan Province is relatively large,and female benzene exposed workers in small and micro private enterprises are the key groups.Occupational protection and occupational health knowledge training should be strengthened to maximize the protection of their occupational health.
