BP is classified by systolic BP (SBP) and diastolic BP (DBP) percentiles for age/sex/height. If SBP or DBP >90th percentile, repeat twice at same office visit before interpreting result.
Normal BP: SBP and DBP <90th percentile
Prehypertension: SBP or DBP 90th percentile to <95th percentile or BP >120/80 mmHg to <95th percentile
Stage 1 Hypertension (HTN): SBP and/or DBP 95th percentile to 99th percentile plus 5 mmHg
Stage 2 HTN: SBP and/or DBP >99th percentile plus 5 mmHg
Since diastolic HTN rarely occurs without systolic HTN in children, the SBP percentile tables on the next page can be used for HTN screening. If a childs SBP on screening is classified as prehypertension or HTN, then both SBP and DBP percentiles should be determined using the tables in the complete report: The Fourth Report on the Diagnosis, Evaluation, and Treatment of High Blood Pressure in Children and Adolescents.
