Abstract

Objectives. This study assessed the health effects of occupational benzene exposure to inform preventive strategies. Methods. Occupational health surveillance data for benzene-exposed workers in Nanning (2020-2024) were obtained from the China Occupational Disease and Health Hazard Factors Monitoring Information System. Demographic, occupational and physical examination data were analyzed using χ² tests and multivariate logistic regression. Results. Abnormalities occurred in complete blood count (CBC) (4.47%), liver function (5.95%), electrocardiogram (ECG) (14.10%) and blood pressure (BP) (13.69%). Female workers had higher odds of CBC abnormalities (odds ratio [OR] 1.352) but lower odds of liver function (OR 0.362), ECG (OR 0.813) and BP (OR 0.572) abnormalities than males. Older age was associated with more ECG and BP abnormalities but fewer liver function abnormalities. Longer employment and manufacturing work (OR 1.735) increased the CBC abnormality risk. Conclusion. Occupational benzene exposure is associated with multifactorial health risks, warranting coordinated prevention by governments, enterprises and workers.

职业苯暴露与工人健康结果：南宁市一项横断面研究

目标。本研究评估了职业性苯暴露对健康的影响，为预防策略提供信息。方法。南宁市苯暴露工人2020-2024年职业健康监测数据来源于中国职业病与健康危害因素监测信息系统。采用χ2检验和多元logistic回归分析人口统计学、职业和体格检查资料。结果。全血细胞计数（CBC）（4.47%）、肝功能（5.95%）、心电图（14.10%）和血压（BP）（13.69%）出现异常。女性工人CBC异常的几率高于男性（比值比[OR] 1.352），但肝功能（OR 0.362）、心电图（OR 0.813）和血压（OR 0.572）异常的几率低于男性。年龄越大，心电图和血压异常越多，肝功能异常越少。较长的就业和制造业工作（OR为1.735）增加了CBC异常风险。结论。职业性苯接触与多因素健康风险有关，需要政府、企业和工人协调预防。
