Blood pressure in childhood. The National Health Examination Survey.

Data were analyzed from the U.S. Health Examination Survey (Cycle II) to determine relationships between blood pressure and other characteristics. This survey examined a national probability sample of children aged 6-11 years. Significant relationships were found for blood pressure and the following variables: chronological and skeletal age, skinfold thickness (adiposity) and other anthropometric measurements, pulse rate, and systolic murmurs. These relationships may be interpreted as indicating important relationships between blood pressure and growth, adiposity, and hemodynamic manifestations of cardiac output. Data from this representative population portray blood pressure relationships in childhood.
