Screening for hypertension in adolescents: the search for normal values

Area of Science:

• Pediatrics
• Cardiology
• Public Health

Background:

• Adult hypertension poses a significant healthcare challenge.
• Early identification of juvenile hypertension may reveal remediable risk factors.
• Establishing normal blood pressure ranges for children is crucial for intervention.

Purpose of the Study:

• To identify adolescents with high blood pressure for further evaluation.
• To determine the range of adolescent blood pressures in a specific population.
• To raise awareness of hypertension and cardiovascular risk factors in youth.

Main Methods:

• A hypertension detection and referral survey was conducted.
• Blood pressures of 7,498 New Orleans high school students (ages 14-18) were assessed.
• Peer group analysis by age, sex, and race was performed.

Main Results:

• Blood pressure variations were observed across age, sex, and race, with some divergence from the 'tracking' effect.
• Black boys showed a notable increase in diastolic blood pressure around age 16.
• Blood pressures exceeding the 90th percentile (140-150/84-90 mm Hg for boys, 130-140/84-90 mm Hg for girls) were identified as referral criteria.

Conclusions:

• The study provides valuable data on adolescent blood pressure ranges and identifies specific demographic groups at higher risk.
• The 90th percentile serves as a recommended criterion for referring adolescents for further medical evaluation.
• Increased awareness and cooperative screening efforts are vital for managing juvenile hypertension and preventing future cardiovascular issues.
