Blood pressure levels in school-age Japanese children : the Hisayama study.
Blood pressure (BP) measurements were obtained on a total of 6325 children (3294 boys and 3031 girls), aged 6-14 years, in Hisayama, Japan.
All BPs were recorded in a sitting position by trained observers in a standardised manner.
Standard mercury sphygmomanometers were used with commercially available cuffs, selected according to the arm circumference.
Cuff size no. 3 (bladder width 9 cm, length 23 cm) was the one most commonly selected in 84% of elementary schoolers aged 6-11 years and in 35% of junior high schoolers aged 12-14 years.
Mean systolic BPs (SBPs) increased from 89 mm Hg at age 6 years to 108 mm Hg at 14 years (a 21% increase) for boys and from 88 mm Hg to 102 mm Hg (a 16% increase) for girls.
Diastolic BP (DBPs, Korotkoff phase IV, KIV) increased from ages 6 to 14 years to the same degree, from 58 mm Hg to 72 mm Hg (a 24% increase) for boys and from 58 mm Hg to 70 mm Hg (a 21% increase) for girls.
The increase in DBP (Korotkoff phase V, KV) was greater, from 48 mm Hg to 63 mm Hg (a 30% increase) for boys and from 48 mm Hg to 61 mmHg (a 28% increase) for girls.
The increase in mean SBP for adolescent boys was greater compared with that of girls ; however, separation of age-specific values by sex was not observed for mean DBP (KIV) and DBP (KV).
The cross-sectional relation between age and mean SBP levels was not linear.
