Effect of home blood pressure and gender on estimates of the familial aggregation of blood pressure. The Tecumseh Blood Pressure Study.
Why the study?
Does self-reported home blood pressure measurement improve heritability estimates of blood pressure compared to clinic-office readings in first-degree relatives?
Population
380 siblings (average age, 31.4 years) from the Tecumseh Blood Pressure study
Comparison
Self-reported home blood pressure readings vs Clinic-office setting blood pressure readings
Design
Cross-sectional
Follow-up
1 week

Implication
Home BP yields equivalent sibling correlations to office readings; hypothesis-generating and should not yet change heritability assessment practices.
Structured PICO

P
Population
380 siblings (average age, 31.4 years) from the Tecumseh Blood Pressure study
I
Intervention
Self-reported home blood pressure readings (average of 14 readings taken over a 1-week period)
C
Comparator
Clinic-office setting blood pressure readings (average of two seated readings)
O
Outcome
Correlation coefficients of blood pressure between siblings and between offspring and parentssurrogate
Home blood pressure readings do not improve heritability estimates of blood pressure compared to clinic readings in first-degree relatives.
