Association of office and ambulatory blood pressure with blood lead in workers prior to occupational exposure

In view of decreasing lead exposure and guidelines endorsing ambulatory above office BP measurement, we re-assessed association of BP with blood lead (BL) in 236 newly employed men (mean age, 28.6 years) without previous lead exposure not treated for hypertension. Office BP was the mean of five auscultatory readings at one visit. 24-h BP was recorded at 15- and 30-minute intervals during wakefulness and sleep. BL was determined by inductively coupled plasma mass spectrometry. Systolic/diastolic office BP averaged 120.0/80.7 mm Hg and the 24-h, awake and asleep BP 125.5/73.6, 129.3/77.9 and 117.6/65.0 mm Hg, respectively.
