Systolic and diastolic blood pressure levels for girls betwen 1 and 17 years of age and 50th percentile of height, indicating normal, prehypertension and hypertension levels

BP (blood pressure) levels for girls by age and 50th percentile of height. The upper two curves correspond to the 90th and 95th percentiles for SBP (systolic blood pressure), and the lower ones to the 90th and 95th percentiles for DBP (diastolic blood pressure).
— BP below the blue lines (90th percentiles) is normal.
— BP between the blue (90th) and the red lines (95th percentile) is prehypertension. In adolescents, BP equal to or exceeding 120/80 mmHg is prehypertension, even if this figure is less than the 90th percentile.
— BP above the red lines (greater than the 95th percentile) may be hypertension.
BP levels vary according to the youngster's height. The chart only considers the median height (50th percentile) for the US population. Therefore the user should be cautious in interpreting the readings, and ask the physician's advice in case of doubt.
