【摘要】 目的 分析天津市苯作业工人健康状况，为制定本市职业病预防控制措施提供科学依据。方法 收集2020年天津市职业健康监护资料，选择10 658名苯作业在岗工人作为暴露组，采用配对的方法选择10 658名非苯作业工人作为对照组，收集年龄、工龄、性别、企业经济类型、企业规模、行业分类、用人单位所属地区等信息。采用单因素和多因素非条件logistic回归分析苯暴露工人基本信息、职业史、企业信息与工人血象异常的关系。结果 苯暴露组工人血象异常率为3.26%，高于对照组工人的2.38%，差异有统计学意义（χ2=14.809,P<0.01）。单因素logistic回归分析显示，女性（OR=2.79,95%CI:2.25～3.47,P<0.01）、高工龄（OR=1.04,95%CI:1.03～1.05,P<0.01）、用人单位所属地区为郊区的企业（OR=1.49,95%CI:1.12～1.97,P<0.01）的苯作业工人血象异常的风险较高。多因素logistic回归分析显示，女性（OR=3.01,95%CI:2.41～3.77,P<0.01）、高工龄（OR=1.09,95%CI:1.07～1.11,P<0.01）、低年龄（OR=0.95,95%CI:0.93～0.96,P<0.01）、微型企业（OR=2.18,95%CI:1.13～4.17,P<0.05）、小型企业（OR=1.66,95%CI:1.17～2.37,P<0.01）、用人单位所属地区为郊区的企业（OR=1.46,95%CI:1.09～1.95,P<0.05）的苯作业工人血象异常的风险较高。结论 天津市应重点关注女性、高工龄组苯作业工人血象异常情况，加强对低年龄组苯作业工人的健康宣传教育。重点关注微、小型企业及用人单位所属地区为郊区的企业的监督管理，定期开展苯作业工人职业健康检查，保护苯作业工人的健康。更多还原

【Abstract】 Objective To analyze the health status of benzene exposed workers in Tianjin,provide a scientific basis for the development of preventive and control measures for occupational diseases in the city. Methods The information on occupational health surveillance in Tianjin in 2020 were collected,10 658 workers working in benzene operations were selected as the exposed group,and 10 658 workers working in non-benzene operations were selected as the control group by the matching method. The data on age,length of service,gender,economic type of enterprise,enterprise size,industry classification,and region to which the employer belongs were collected. The univariate and multivariate unconditional logistic regression were used to analyze the relationship between basic information,occupational history,enterprise information of benzene exposed workers and workers’ abnormal hemogram. Results The rate of abnormal hemogram in the benzene exposed group was 3.26%,which was higher than that in the control group(2.38%),with a statistically significant difference （χ2=14.809,P<0.01）. The univariate logistic regression analysis showed that benzene exposed workers who are female(OR=2.79,95%CI:2.25-3.47,P<0.01),long working age(OR=1.04,95%CI:1.03-1.05,P<0.01),and enterprises whose employer’s region was suburban(OR=1.49,95%CI:1.12-1.97,P<0.01) had the higher risk of abnormal hemogram. The multivariate unconditional logistic regression showed that benzene exposed workers who are female(OR=3.01,95%CI:2.41-3.77,P<0.01),long working age(OR=1.09,95%CI:1.07-1.11,P<0.01),young age(OR=0.95,95%CI:0.93-0.96,P<0.01),micro-enterprises(OR=2.18,95%CI:1.13-4.17,P<0.05),small enterprises(OR=1.66,95%CI:1.17-2.37,P<0.01),and enterprises whose employer’s area was suburban(OR=1.46,95%CI:1.09-1.95,P<0.05) had the higher risk of abnormal hemogram. Conclusion In Tianjin,it is necessary to focus on the abnormal hemogram of benzene-exposed workers of female and high working age group,strengthen the health promotion and education in the lower age group,pay attention to the supervision and management of micro and small enterprises and enterprises with employers in suburban areas,and conduct regular occupational health examination for benzene-exposed workers,to protect the health of benzene-exposed workers.更多还原
