Dr. Greene's Answer
Boys generally have higher normal blood pressures than girls of the same age. Taller children have higher normal blood pressures than shorter children of the same age. For an average 5 year old girl, a normal blood pressure would be less than 106/68. A complete table of normal blood pressures for children can be found at www.nhlbi.nih.gov/guidelines/hypertension/child_tbl.htm.
