Changing Relationship Between Home and Office Blood Pressure With Increasing Age in Children: The Arsakeion School Study
Key result
In healthy children, average office systolic blood pressure was slightly lower than home blood pressure by 0.6 mm Hg (95% CI 0.1-1.1; P=0.01), a difference that was eliminated in older adolescents.
Why the study?
Does age affect the difference between home and office blood pressure in healthy children?
Population
765 healthy subjects aged 6-18 years (mean age 12 +/- 3 years)
Comparison
Home blood pressure monitoring vs Office blood pressure measurements
Design
Cross-sectional

Implication
Age attenuates small office-home SBP differences in healthy youth; extends cross-sectional observations but does not yet inform diagnostic thresholds.

Type
Cross-Sectional (n=765)
Structured PICO
Does age affect the difference between home and office blood pressure in healthy children?
P
Population
765 healthy children and adolescents aged 6-18 years.
E
Exposure
Home blood pressure (HBP) monitoring (3 days, 12 readings using electronic devices validated in children)
C
Comparator
Office blood pressure (OBP) measurements (2 visits, 6 readings)
O
Outcome
Difference between HBP and OBP and the effect of age on this differencesurrogate
Main Result
Mean Difference: 0.6 (95% CI 0.1–1.1)
p-value: p=0.01
In children, home blood pressure is slightly higher than office blood pressure, but this difference is eliminated after age 12.

Stergiou et al. (2007) conducted a cross-sectional in Healthy (n=765). Home blood pressure monitoring vs. Office blood pressure monitoring was evaluated on Difference between home and office systolic blood pressure (MD 0.6 mm Hg, 95% CI 0.1, 1.1, p=0.01). In healthy children, average office systolic blood pressure was slightly lower than home blood pressure by 0.6 mm Hg (95% CI 0.1-1.1; P=0.01), a difference that was eliminated in older adolescents.
