• Blood pressure (BP) measurements were obtained from 522 healthy young children aged from 3 months to 3 years in Hisayama, Japan. The measurements were performed using a Doppler ultrasound device applied to children who were awake and sitting quietly on their mothers' laps. This method of obtaining BP was successful in 80% to 90% of children aged 3, 6, and 36 months, and in 60% to 70% of children aged between 12 and 18 months. Mean systolic BP varied from 88 mm Hg at 3 months to 96 mm Hg at 3 years and showed a tendency to elevate with increasing age, with the increment being the greatest between ages 3 and 6 months. Mean diastolic BP was constant throughout the first three years of life.
