Cardiac Autonomic Modulation is a Key Factor for High Blood Pressure in Adolescentes.

Background: The interest regarding hypertension among children and adolescents has increased since the blood pressure rating system was updated to be compared with the adult rating system, changing the terminology from "normal high" to "prehypertension".

Objective: This study aimed to analyze the association between cardiac autonomic modulation and pressure levels of adolescents.

Methods: 203 adolescents were grouped according to systolic blood pressure (SBP) and diastolic blood pressure (DBP).

Cardiac autonomic modulation of adolescents with different levels of sleep quality.

Unlabelled: Evaluate the cardiac autonomic modulation of adolescents with different levels of sleep quality.

Methods: Adolescents aged 11 to 17 years who presented themselves an explanation of the project with consent form signed by participated in the study. Anthropometric and hemodynamic data collected, and questionnaires.
