Abstract
The aims of this study were to determine 24 h blood pressure (BP) levels in a sample taken from a normal British population, and to investigate factors contributing to variation within the sample. Two hundred and eighty-two Caucasian subjects, with no known hypertension or cardiovascular disease were recruited from local light industry and a general practice population. Office and 24 h BPs were measured. The mean office BP was 120/75, ambulatory mean awake 115/72 and mean asleep 97/58 mm Hg. Males had a small but significantly higher mean office and awake BP but there were no differences in asleep BP. Multiple step-wise regression with age, gender, weight and height showed age to be the best predictor of variation in office BP and awake and asleep diastolic BP. However, age accounted for only a small amount of the variation and did not contribute towards the variation in systolic BP. The two standard deviation upper limits for this population for awake, asleep and overall BP were 136/86, 121/73 and 131/82 mm Hg, respectively. In conclusion, these data providing information on 24 h BP in a healthy British population may be of value in the clinical interpretation of 24 h ambulatory BP recordings in patients with suspected hypertension.
