Normal Blood Pressure in children and Definition of Hypertension
Normal blood pressure in children varies according to age, gender and height of a child. There are normal values of systolic and diastolic BP which are recorded in large number of school children and like growth charts, percentile charts of BP are available for different ages as per 3rd Task for blood pressure in children which is compiling data from USA and Europe. If 3 separate BP recordings of a child are above 95th centile for age, gender and height it is designated as hypertension or high BP.
