In 2003, the National Health and Nutrition Examination Survey (NHANES) provided a large national database on normative BP levels throughout childhood and revised BP tables to include the 50th, 90th, 95th, and 99th percentiles by gender, age, and height. These data permit clinicians to identify children with abnormally elevated BP and to define hypertension in children and adolescents as systolic BP and/or diastolic BP that, on repeated measurement, is above the 95th percentile (higher than 120/80 mm Hg).
