There isn't a specified blood pressure level that is considered normal for all children, says the American Heart Association. Normal blood pressure varies with each child and depends on many factors such as gender, age and height.
Because normal blood pressure is different for each child, a doctor must calculate a healthy blood pressure based on the child’s gender, height and age, explains the American Heart Association. Children with a family history of high blood pressure, who are overweight, or who are African American, may have an elevated risk for high blood pressure. High blood pressure in children can generally be managed with a heart-healthy diet, regular physical activity and by maintaining a healthy weight.
