^aA high childhood blood pressure z score was defined so that the upper 20% or 25% of the children would be classified as having a high level. The prevalence of adult hypertension was 18.6% and was based on a systolic blood pressure (SBP) ≥140mm Hg, a diastolic blood pressure ≥90mm Hg, or reported use of antihypertensive medications. The childhood blood pressure level represents the mean of the 3 measurements from the first observer averaged over all examinations for that subject.
