对１０８名铅作业工人的血铅、血压进行相关和多元逐步回归分析。结果表明，铅作业工人收缩压和舒张压，与血铅含量呈正相关（ｒ＝０．４４７６，Ｐ＜０．０１；ｒ＝０．３５３４，Ｐ＜０．０１），血铅含量每升高１μｇ／ｄｌ，收缩压和舒张压分别升高３７．３Ｐａ和２５．８Ｐａ。说明铅对作业工人的血压有一定的影响
Correlation and multiple stepwise regression analysis of blood lead and blood pressure of 108 lead workers were conducted. The results showed that systolic blood pressure and diastolic blood pressure of lead workers were positively correlated with blood lead levels (r = 0.4476, P <0.01; r = 0.3534, P <0.01) 1μg / dl, systolic and diastolic blood pressure increased 37.3Pa and 25.8Pa respectively. This shows that lead has a certain impact on the blood pressure of workers
