Blood pressure in a sample of canadian school children.

Before attempting any preventive action to control essential hypertension, we must know who is at risk. Normative data are needed for blood pressure, especially that measured in a non-clinical setting. This study measured blood pressure in a group of 2004 students aged six to 18. Their pressures were taken at school, and compared with those found in other studies where the pressures were taken in a clinical setting. A significant difference was found, suggesting that further investigation is needed into normative data.
