摘要
目的分析核电站检修工人血象变化情况。方法本研究采用整群抽样方法对某核电检修公司141名男性检修工人进行调查。采用重复测量资料的方差分析评价历年红细胞、白细胞和血小板计数是否发生改变;不同年龄工人血细胞计数是否有差异以及年龄和时间是否具有交互作用。结果核电站检修工人红细胞数随时间变化而发生改变(F=40.89,P<0.001),时间与年龄具有交互作用(F=3.74,P=0.005);白细胞数随时间变化而发生改变(F=5.78,P<0.001),时间与年龄无交互作用(F=0.77,P=0.578);血小板数随时间变化而发生改变(F=30.37,P<0.001),时间与年龄无交互作用(F=0.67,P=0.668)。不同年龄工人红细胞、白细胞和血小板计数均无差异(P>0.05)。结论核电站检修工人各血细胞数随时间变化而发生改变,总体规律为先降低再升高,需要进一步研究。
Objective To explore the variation of complete blood count of maintenance workers in a nuclear power plant.Methods Analysis of variance was used to analyze the repeated measurement data and evaluate whether the counts of red blood cells,white blood cells and platelets have changed over the years,whether differences in blood cell counts among workers of different ages were significant,and whether age is associated with time.Results Erythrocyte counts of nuclear power plant maintenance workers changed over time(F=40.89,P<0.001),and time was associated with age(F=3.74,P=0.005);Leukocyte count changed over time(F=5.78,P<0.001),and time was not associated with age(F=0.77,P=0.578);Platelet counts changed over time(F=30.37,P<0.001),and time was not related to age(F=0.67,P=0.668).There was no difference in erythrocyte,leukocyte and platelet counts among workers of different ages(P>0.05).Conclusion The number of blood cells of nuclear power plant maintenance workers decreased at first and increased to a higher level.Further study is needed to better understand the phenomenon.
