Simple formulas for screening abnormal blood pressure in children and adolescents.


Childhood hypertension has been extensively focused on in the past decades because of its increasing incidence, which is related to physicians' awareness and the increasing number of obese children. Age, gender, and body size are the main determinants of blood pressure in children.

Although these tables provide a reasonable basis, they are intricate and height percentile is needed for final diagnosis. Many attempts have been done to decrease such complexity. We present new formulas that are concise and memorable, and will help physicians to screen prehypertensive and hypertensive pediatric patients.
