A blood pressure chart for children is available on the National Heart, Lung, and Blood Institute website. The chart lists normal systolic and diastolic blood pressures based on a child's gender, age and height percentile.
Blood pressure measures the force of blood as it travels through the blood vessels in the body, according to WebMD. In people with high blood pressure, the blood puts too much pressure on the vessels, which can lead to certain health conditions. High blood pressure in children increases their risk of developing heart disease, kidney disease and stroke. Children experience an increased risk of high blood pressure if they are obese, have a family history of high blood pressure or have sleep disorders.
Treatment of high blood pressure in children may include medications, dietary changes and weight control, notes WebMD. A diet that incorporates plenty of fruits, vegetables and whole grains and limits sodium and saturated fat can help reduce blood pressure. Overweight children with high blood pressure may need to lose weight through exercise and a healthy diet. Because secondhand smoke can increase blood pressure, it's best to keep children away from tobacco smoke. Medications used to control blood pressure in children include diuretics, ACE inhibitors and beta blockers.
