title: Anthropometric data, urinary electrolytes excretion, and blood pressure in adolescents.
abstract: Relationships between arterial pressure, age, sex, anthropometric measurements, body fat, and urinary excretion of electrolytes were examined in a group of 120 adolescents from 11 to 14 years of age. Body weight and triceps skinfold thickness are two variables that have the highest correlation with arterial pressure levels, especially among girls. Only a slight correlation was found between urinary excretion of sodium and arterial hypertension. The apparent contradiction between positive correlation of fat percent and arterial pressure and the negative correlation between urinary excretion of sodium and arterial pressure can possibly be explained by the low sodium content of the diet of the subjects studied. Their typical Mediterranean diet was abundant in fresh food, mainly based on carbohydrates (macaroni, bread, vegetables), rather than conserved foods in which salt plays an important role in the conservation process (butter, bacon, salad, etc.), typical of the continental diet.
