Systolic BP increased by 11.1 mm Hg in boys and 3.2 mm Hg in girls over 5 years; changes in height explained half the increase in boys and virtually all in girls, while a 1 unit increase in BMI was associated with a 0.7 mm Hg increase in systolic BP in both sexes.

Overview

Height gains largely explain sex differences in adolescent SBP trajectories; extends observational data but leaves causal mechanisms and interventions open.

Structured PICO

Do changes in anthropometric characteristics explain sex differences in systolic blood pressure increases during adolescence?

P
Population
1293 adolescents in Montreal, Canada, assessed at mean ages 12.8, 15.2, and 17.0
I
Intervention
Changes in anthropometric characteristics (height, BMI, waist circumference, and triceps and subscapular skinfold thickness)
O
Outcome
Changes in systolic blood pressure over 5 yearssurrogate

Sex differences in systolic blood pressure increases during adolescence are largely driven by differences in height gains, whereas weight and body fat gains affect blood pressure similarly in both sexes.
