title: [Arterial pressure in childhood. I: Relation to age. (collection of data relative to 3,737 pupils of elementary and high school between the ages of 6 to 14 years)].
abstract: Research relating blood pressure levels of 6-14 years-old age schoolchildren has been carried into the whele school-population of Chivasso (Turin) town. Three kinds of armbands of different widths and lengths were used according to age. In conformity with Long's suggestions, the correction factors were used for the age-groups from 6 to 7 years and 8 to 11. On the grounds of the levels taken the quantiles were calculated. The graphs show the shape of the 5th, 25th, 50th, 75th, and 95th percentiles, related to the systolis and diastolic pressures and to the age of the child. The results showed a continous increase in the shape of the levels, which did not depend on the sex variant. A spike in the 9th year can be related to the fact that the correction factor can be less than it should be. The decrease in the 11th year can be put down to the fact that the correction for the armband has not been carried out from the 12th year onwards. 6.52% of schoolchildren have systolic and/or diastolic blood pressure greater than 95 degrees C.
