AAP 2017 Criteria for Blood Pressure Classification in Children

The American Academy of Pediatrics (AAP) 2017 guidelines classify pediatric blood pressure into two age-based systems: percentile-based for children aged 1-12 years, and absolute values (adult thresholds) for adolescents ≥13 years.

Children Age 1 to <13 Years (Percentile-Based)

BP percentiles are adjusted for age, sex, and height. Always use the lower value when comparing percentile-based and absolute cutoffs.
CategoryCriteria
NormalSBP/DBP < 90th percentile
Elevated BP≥ 90th percentile OR ≥ 120/80 mmHg, to < 95th percentile
Stage 1 Hypertension≥ 95th percentile to < (95th percentile + 12 mmHg) OR 130/80 to 139/89 mmHg
Stage 2 Hypertension≥ 95th percentile + 12 mmHg OR ≥ 140/90 mmHg

Adolescents Age ≥13 Years (Adult Thresholds)

CategorySBPDBP
Normal< 120 mmHgand < 80 mmHg
Elevated BP120-129 mmHgand < 80 mmHg
Stage 1 Hypertension130-139 mmHgor 80-89 mmHg
Stage 2 Hypertension≥ 140 mmHgor ≥ 90 mmHg

Key Points

  • Normal in children 1-12 years = BP < 90th percentile (unlike adults, where < 120/80 is the cutoff)
  • The "Elevated BP" category replaced the old "Prehypertension" term from the 2004 Fourth Report
  • The 99th percentile threshold is no longer used to define stages; it was replaced by the 95th percentile + 12 mmHg concept
  • Hypertensive crisis (formerly urgency/emergency) is now termed "acute severe hypertension" - defined as symptomatic presentation; the 99th percentile still guides this evaluation clinically
  • Diagnosis requires ≥3 separate measurements on different occasions before labeling a child hypertensive

Treatment Threshold

  • Long-term BP goal: < 90th percentile, or < 130/80 mmHg in adolescents, to reduce end-organ damage and future cardiovascular risk
  • Tintinalli's Emergency Medicine, Table 137-3
  • Fuster and Hurst's The Heart, 15th Edition, Table 5-1
A 2017 AAP guideline review by Dionne (PMID 29035421) confirms these updated classifications improve recognition and diagnosis of HTN in children and adolescents.
