Abstract: 

Chronic exposure to low levels of lead has been shown to cause hypertension in humans.In this study we examined the relationship between blood lead level and blood pressure and hypertension prevalence in a population-based sample of hypertensive and normotensive patients in the Shariate and Imam Khomeini hospitals in Iran, Cross sectional samples of 400 patients (age: 40-70), who participated in a physical examination from these hospitals survey conducted from 2002-2003. The range of blood lead levels from patients was 2.65 to 16.48μg/dl. The mean blood lead levels of hypertensive patients (5.103±0.43) were higher than normotensive patients (2.65±0.32). There was a significant difference in mean blood lead levels of hypertensive men (5.57±0.61) and normotensive men (2.16±4.3) in this study. The comparison of blood lead levels of hypertensive women (4.75±0.6) and normotensive women (2.29±0.48) did also show a significant difference (P<0.001). In this population we concluded at levels well below the current US occupational exposure limit guidelines (40 g/dl), blood lead levels are positively associated with both systolic and diastolic blood pressure and risk of both systolic and diastolic hypertension among patients aged 40 to 70 years.
