Purpose: To examine the value of repeated blood pressure screening dur
ing childhood, and exercise testing in adolescence, for predicting res
ting blood pressure at eighteen years. Method: Regular measures of blo
od pressure and other variables in a birth cohort from 7 to 18 years.
Cardiovascular responses to exercise testing at 15 and 18 years. Resul
ts: The best predictors of resting blood pressure at 18 years were bod
y size at 18 years and resting blood pressure at 15 years. Neither exe
rcise and recovery blood pressures at 15 years, nor the way blood pres
sure had tracked through childhood, added importantly to the predictio
n. Conclusions: We question the value of screening for hypertension du
ring childhood, either by regular resting measures or by exercise test
ing in adolescence.
