Implication

Randomized trial examines sleep parameters impacting daytime sleepiness in adolescents, suggesting interventions should target neurophysiology and chronotype.

Key Points

The study aims to investigate the contributions of sleep duration, neurophysiology, and chronotype to daytime sleepiness in adolescents.
Involved 45 healthy adolescents (mean age 13.9) using multi-night actigraphy and EEG recording.
Daytime sleepiness was measured with the Epworth Sleepiness Scale for Children and Adolescents.
Regression analyses were conducted to identify correlates of daytime sleepiness, controlling for age and sex.
Lower sleep spindle density and stronger evening circadian preference were significantly associated with increased daytime sleepiness.
These factors explained 45.3% of the variance in subjective daytime sleepiness.
Sleep duration alone was insufficient to account for daytime sleepiness in this group.
