扬州市苯作业人员血常规检查结果分析

Analysis on blood routine examination Results for the benzene-exposed workers of Yangzhou City

目的了解扬州市苯作业人员的血常规状况,探讨不同年龄、行业、工龄、性别对苯作业人员血常规检查结果的影响。方法收集扬州市2014年3 003名苯作业人员的职业健康检查结果,对资料进行统计分析。结果 3 003名苯作业人员血常规异常检出率为6.9%,WBC和中性粒细胞减少检出率分别为4.3%和5.2%。不同年龄、行业组苯作业人员血常规异常检出率比较,差异无统计学意义(P>0.05)。工龄≥10a组WBC的减少检出率高于工龄<10a组,差异有统计学意义(P<0.05)。男性组WBC减少检出率高于女性组,差异有统计学意义(P<0.01)。而不同工龄、性别组中性粒细胞和血小板减少检出率比较,差异无统计学意义(P>0.05)。化工行业男性组和女性组WBC减少检出率分别为5.2%和2.0%,男性组高于女性组,差异有统计学意义(P<0.01)。结论苯作业人员血常规异常主要表现为WBC和中性粒细胞的减少,工龄、性别对苯作业人员的血常规检查结果有一定的影响,应加强对苯作业人员的健康管理和防护,尤其是化工行业的男性员工。

Objective To understand the blood Results of routine examination of benzene-exposed workers and explore influence of blood test Results of the age,industry,working age and gender for the benzene-exposed workers.Methods Analysis was made on the data collected from the occupational physical examination of the 3 003benzene-exposed workers in Yangzhou City of 2014.Results Among the 3 003benzene-exposed workers,the abnormal rate of blood routine detection was 6.9%,the detection rates of reduction of WBC and neutrophils was 4.3%and 5.2%,respectively.The difference of abnormal rate of blood routine was not statistically significant in different age groups and industries（P〉0.05）.The detection rate of WBC reduction of workers working for≥10awas higher than that with working for10a,the difference was statistically significant（P〈0.05）.The difference of detection rate of WBC reduction between male and female was statistically significant（P〈0.01）.The difference of detection rate of reduction of neutrophils and PLT was not statistically significant in different working yeas and gender（P〈0.05）.In chemical industry,the detection rates of WBC reduction in male and female group was 5.2% and 2.0%,respectively.The difference was statistically significant（P〈0.01）.Conclusions The blood routine abnormalities of benzene-exposed workers were reduction of the WBC and neutrophils.Working years nd gender have a certain effect on the blood test Results of benzene-exposed workers.It is suggested that management and worker health protection of benzene-exposed workers should be strengthened,especially the male employees of the chemical industry.
