[Arterial hypertension in adolescents].

The clinical cases of 391 men and 609 women, adolescent all of them, are included in this study. T.A. values were obtained by the Korotkoff method and the lower figures in both measurements analized. The mean value for the men's cases were 112/72/67 and for the women's cases 105/71/67 respectively for K1, K4 and K5. The difference between the sistolic pressures is significant. Taking the mean men and 126/89/86 for the women. Such values might represent the higher values plus two standard derivations it was possible to obtain 139/92/88 for the normal limit. At higher values we found K1 at 1% for men and 10% for women; K4 at 1.2% for men and 5.7% for women; for K5 at 1.1% for men and 2.2% for women. There is a direct relation between obesity and higher figures in T.A. for K1 and K4 in both sexes (p.0.01). The use of too much salt influenced the coming up of K4 to (p.0.01).
