- In pediatric hypertension, using the most recent guidelines increases hypertension prevalence among high-risk youth.
- The guidelines also increase sensitivity for target organ damage (TOD) in this population.
Why this matters
- Hypertension prevalence was
- 8% (6% stage I; 2% stage II) with old guidelines,
- 13% (10% stage I; 3% stage II) with new ones (P=.007).
- TOD identification (e.g., carotid-intima thickness, diastolic function) was similar, but newer guidelines had increased sensitivity.
- For example, older and new guidelines respectively pinpointed 20% and 31% with hypertensive left ventricular mass (P<.001>
- 364 children (65% female; age, 15.1±2.1 years):
- 213 were obese.
- 111 had type 2 diabetes.
- TOD was measured, BP categorization by guideline (older/newer) was compared.
- Funding: NIH.
- Causation not established in associations.
- High-risk population (obesity, diabetes), so generalizability not known.
