Analysis on influencing factors of abnormal blood cells in benzene-exposed workers in a shoe factory in Tianjin

Abstract

Abstract: Objective To investigate the influencing factors of blood cell abnormalities in benzene-exposed workers in Tianjin. Methods In 2021,the occupational health inspection data of benzene-exposed workers in a shoe factory in Tianjin were collected,and the epidemiological investigation was conducted through self-designed questionnaires. The logistic regression was used to assess the impact on blood cell abnormalities in benzene-exposed workers from personal general condition,occupational history,past and family medical history,personal behavior,female physiological and reproductive status. Results The occupational health examination data of 95 benzene-exposed workers were collected,and they cooperated with completing the epidemiological questionnaire. There were 66 benzene-exposed workers in the normal group and 29 benzene-exposed workers in the abnormal blood cells group. The rate of abnormal blood cells in females was higher than that in males（χ²=5.033,P<0.05）. The rate of abnormal blood cells in premenopausal female workers was higher than that in postmenopausal female workers（χ²=7.469,P<0.01）. The rate of abnormal blood cells in benzene-exposed workers aged 18-<50 years old was higher than that in those aged ≥50 years old（χ²=5.265,P<0.05）. The logistic regression analysis found that benzene workers with low education had higher risk of blood cell abnormalities than workers with medium and high education（OR=4.951,95%CI：1.078-22.748）,and premenopausal female benzene workers have higher risk of blood cell abnormalities than menopausal female workers（OR=0.127,95%CI：0.033-0.487）. Conclusion In occupational health management,in addition to strengthening occupational health monitoring,it is necessary to focus on high-risk factors such as educational level and female physiology,strengthen the management of high-risk groups,and prevent the occurrence of occupational diseases.
