Blood pressure in children, adolescents and young adults.
The question of whether blood pressure is one of the main risk factors for cardiovascular diseases in childhood has been evaluated in a Study of Cardiovascular Risk in Young Finns. In the second follow-up study, carried out in 1986, blood pressure was successfully measured in 2500 individuals aged nine to 24 years using a random zero sphygmomanometer. The mean systolic blood pressure in girls rose from 102 mmHg (95th percentile 119 mmHg) at age nine to 116 mmHg (138 mmHg) at age 24 and that in boys from 102 mmHg (95th percentile 121 mmHg) to 128 mmHg (148 mmHg). Diastolic blood pressure was more often measurable using Korotkoff's 5th than the 4th phase. The values observed were similar to those reported by the Second Task Force on Blood Pressure Control in Children, but owing to differences in the methods used to measure blood pressure it cannot be reliably concluded that the blood pressures were similar in the two series. Even in childhood blood pressure measurement is important, and since it changes with the physical size of the child, observations should be compared with normal values such as those reported here. No data are yet available to suggest that children with blood pressure values in the high normal range would benefit from interventions. Thus normal blood pressure value curves should be applied with caution when assessing children.
