Key result
Poor sleep quality in adolescents is linked to lower cardiac autonomic modulation.
Why the study?
The cardiac autonomic modulation differences in adolescents with varying sleep quality levels were not well characterized.

Does poor sleep quality affect cardiac autonomic modulation in adolescents?
Poor sleep quality in adolescents is associated with reduced cardiac autonomic modulation, characterized by lower vagal tone and higher sympathetic dominance.
Sleep quality differences should not alter adolescent autonomic assessment; leaves open need for longitudinal confirmation.
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.

Filho et al. (2020) conducted a cross-sectional in Sleep quality. Poor sleep quality vs. Good sleep quality was evaluated on Cardiac autonomic modulation. Poor sleep quality in adolescents was associated with lower cardiac autonomic modulation, including decreased vagal modulation, increased LF, decreased HF, and an increased LF/HF ratio.
