Differences between office and ambulatory blood pressures in children and adolescents attending a hospital hypertension clinic

Abstract

There is a common relation both in children and adults between OBP and ABP. It is only because high OBP is common in the elderly, and the lowest OBP is usually found in young children that large positive OBP-ABP differences have been associated with old age, and negative differences with childhood. OBP-ABP differences, often defined as white-coat effect, can have different directions and are likely to be largely due to regression to the mean.
