title: Effect of lead on blood pressure in occupationally nonexposed men.
abstract: To determine if low-level exposure to lead has an effect on arterial blood pressure, demographic and clinical data of a group of 507 males without any occupational exposure to lead were analyzed in a retrospective study. The following variables were included in the analysis: age, height, weight, nicotine consumption, alcohol intake, blood lead, systolic blood pressure, diastolic blood pressure, and erythrocyte count. The effects of the variables age, weight, height, alcohol intake, nicotine consumption, and blood lead on blood pressure were investigated by stepwise linear regression analysis. The diastolic as well as the systolic blood pressure was significantly influenced by Body Mass Index, age, and alcohol. A significant effect of lead could be found only for diastolic blood pressure. None of the possible interactions were significant enough to merit inclusion in the statistical model. Regarding the strength of the effects on diastolic blood pressure we find that lead ranks after age, weight. In conclusion, this study shows that lead has an effect on diastolic arterial blood pressure in a survey of a group of middle-aged, occupationally nonexposed men.
