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. Results: Analysis of the variables, age, systolic blood pressure, diastolic blood pressure, waist circumference, body fat and body mass index among the groups with good and poor sleep quality did not present a significant difference (p>0.05) in any paired characteristics. Time domain analysis indicated lower values in the vagal modulation with poor sleep quality. In the frequency domain, LF component increased and HF component decreased significantly in the group with poor sleep quality. There was also a statistical difference in the LF/ HF analysis, the group with poor sleep quality presented an increase in this variable. Conclusion: The subjects with poor sleep quality present lower cardiac autonomic modulation.
