Relation between serum uric acid and blood pressure in adolescents

In adults, serum uric acid is positively associated with blood pressure levels. It is also a predictor of the development of hypertension in normotensive adults. The purpose of this study was to examine the relation of serum uric acid to systolic and diastolic blood pressure in adolescents. The data, from Cycle III of the National Health Examination Survey, consisted of a national probability sample of 6768 youths, 12-17 years old, in the United States. With age, height, weight, and sexual maturity controlled, serum uric acid significantly predicted blood pressure in adolescents. This relationship of uric acid and blood pressure was evident in male, but not female, adolescents. In association with findings from adult studies, these results indicate that uric acid levels may be useful indicators of adolescents at risk for hypertension.
