摘要
目的:调查安徽省宿州市交通警察血铅水平,探讨其影响因素。方法:对可能影响血铅(Y∧)的因素即外勤年限(X1)、血红蛋白(X2)、吸烟与否(X3)、血锌(X4)等进行了单因素相关和多因素逐步回归分析。结果:交通警察血铅和尿铅均数为119.79μg/L和6.99μg/L,与对照组(88.38μg/L和5.34μg/L)比较,差异均有统计学意义(P<0.001和P<0.01)。单因素分析表明血铅与外勤年限呈正相关(P<0.001),与血红蛋白呈负相关(P<0.001),多元逐步回归方程为:∧Y=132.95+0.93X1-0.86X2+7.37X3+14.30X4。结论:交通警察血铅有随外勤年限增加呈升高趋势,且使血红蛋白合成受到一定程度抑制。
Objective:To investigate the blood lead levels of traffic police in Suzhou city and the correlative factors. Methods:The blood lead levels of the traffic police in Suzhou and the correlative factors were studied. A mono-factor correlation analysis and multiple stepwise regression analysis were carried out to analyze the possible factors affecting blood lead levels (Y^∧) , such as outdoor-on-duty years( X1 ) ,hemoglobin( X2 ), smok.ing( X3 ) and blood zinc(X4). Results :The average levels of blood lead and urine lead of the traffic police were 119.79 and 6.99 μg/L respectively, which were significantly higher than those of the controls( 88.38 and 5.34 μg/L) (P 〈0.001 and P 〈 0.01 ). In mono-factor correlation analysis, the blood lead levels showed a positive correlation with outdoor-on-duty years ( P 〈 0. 001 ) , and a negative correlation with concentrations of hemoglobin ( P 〈 0. 001 ). In multiple stepwise regression analysis, the regression equation was established as Y^∧ = 132.95 + 0. 93X1 -0.86X2 + 7.37X3 + 14.30X4. Conclusions: It suggests that the blood lead levels rise with the increase of outdoor-on-duty years, and the synthesis of hemoglobin is inhibited to a certain extent.
