Management of Pediatric Hypertension

Diagnosis and Classification

The American Academy of Pediatrics recommends that a blood pressure of 130/80 mmHg in a 9-year-old child represents Stage 1 hypertension and requires confirmation with repeated measurements on three separate occasions before initiating treatment, followed by diagnostic evaluation and lifestyle modifications as first-line therapy 1, 2
Normal blood pressure in a 9-year-old child is defined as less than the 90th percentile for age, sex, and height 1, 2
Elevated blood pressure in a 9-year-old child is defined as greater than or equal to the 90th percentile but less than the 95th percentile for age, sex, and height 1, 2
Stage 1 hypertension in a 9-year-old child is defined as greater than or equal to the 95th percentile for age, sex, and height 1, 2
Stage 2 hypertension in a 9-year-old child is defined as greater than or equal to the 95th percentile + 12 mmHg 2, 3

The American Heart Association recommends that once hypertension is confirmed on three separate visits, initiate a workup including urinalysis, blood chemistry, lipid profile, and hemoglobin A1c and liver function tests if the child is obese 7
Renal ultrasound is recommended if the child is less than 6 years of age to evaluate for secondary causes of hypertension 7
Echocardiogram is recommended at the time of initiating therapy to assess for left ventricular hypertrophy 4

The American Academy of Pediatrics recommends that lifestyle modifications, including dietary changes, weight management, physical activity, and sleep optimization, be initiated immediately upon confirmation of hypertension 4, 5
The American Heart Association recommends that first-line antihypertensive agents, such as ACE inhibitors, angiotensin receptor blockers, calcium channel blockers, and thiazide diuretics, be considered if lifestyle modifications are not effective 1, 2

The American Academy of Pediatrics recommends that the target blood pressure be less than the 90th percentile for age, sex, and height, approximately less than 107-115 mmHg systolic for a 9-year-old, depending on height 4, 6
The American Heart Association recommends that follow-up occur at 6-month intervals, with repeat upper and lower extremity blood pressure measurements, continued lifestyle counseling, and consideration of subspecialty referral if blood pressure remains elevated or progresses 5
