摘要
为了解交警血铅水平及影响因素，对可能影响血铅（ Ｙ）的因素即外勤年限（ Ｘ１）、尿铅（ Ｘ２）、血红蛋白（ Ｘ３）、吸烟与否（ Ｘ４ ）、血锌（ Ｘ５）及年龄（ Ｘ６）进行了单因素相关和多因素逐步回归分析。结果表明交警血铅和尿铅均数为１１９７９μｇ／ Ｌ和６９９ μｇ／ Ｌ，与对照组（８８３８ μｇ／ Ｌ和５３４ μｇ／ Ｌ）差异有显著性。单因素分析表明血铅与外勤年限、尿铅和年龄呈正相关，与血红蛋白呈负相关，多元逐步回归方程为： Ｙ＝ １３２．９５＋ ０．９３ Ｘ１＋ １０．０１ Ｘ２－ ０．８６ Ｘ３＋ ７．３７ Ｘ４ ＋ １４．３０ Ｘ５。交警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。
To study the blood lead levels and their correlative factors for traffic police,a mono factor correlation analysis and multiple stepwise regression analysis on blood lead levels ( Y ) and their correlative factors,such as outdoor on duty years ( X 1 ),urine lead level ( X 2 ),homoglobin ( X 3), smoking ( X 4), blood zinc( X 5 )and age ( X 6) , were carried out The results showed that the average levels for blood lead and urine lead for traffic police were 119 79 and 6 99 μg/L respectively,which were significantly higher than those for controls(88 38 and 5 34 μg/L) In mono factor correlation analysis,blood lead levels showed a positive correlation with urine lead level and age,and a negative correlation with concentrations of homoglobin In multiple stepwise regression analysis,the regression equation was established as Y =132 95+0 93 X 1+10 01X 2-0 86X 3+7 37X 4+14 30X 5 It showed a significant tendency that the blood lead levels increased with the increase of outdoor on duty years and the synthesis of homoglobin was inhibited to a certain extent
