[High blood pressure in children and adolescents: determinant factors]
1Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, RS, Brazil.
Abstract:
OBJECTIVE: To review the state of prevalence of hypertension in childhood and the importance of its possible determinants. METHODS: Analysis of the literature concerned with eleven possible determinant factors - experimental design, internal and external validity. RESULTS AND CONCLUSIONS: Central body fat pattern seems to be a risk factor, while heart rate and tracking would be true markers of future hypertension. Social class, biological maturation, race, sodium intake and genetic factors have not yet been validated through unbiased studies.

In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
