Childhood predictors of high blood pressure.

Longitudinal studies in children have tracked blood pressure through childhood and from childhood into adult life. However, many children do not maintain their rank during these periods of observation. Several of the factors contributing to maintenance of rank order are reviewed, such as initial level of blood pressure, body size, sexual maturation, and family history of high blood pressure. Children with initially high level of blood pressure are more likely to become adults with high blood pressure, particularly if they are obese as children or become obese as young adults, and if they have a positive family history for hypertension.
