The moderating role of subjective daytime sleepiness in the associations between sleep duration and brain morphology in school-aged children.

ABSTRACT:

Study objectives

The alignment between greater sleep demands and heightened neuroplasticity in childhood suggests that sleep plays a key role in brain maturation. While sleep duration is commonly accepted as a marker for adequate sleep, this indicator overlooks differences in individual sleep needs. Subjective perception of sleepiness may offer additional insight into sleep insufficiency relative to individual needs. This study aimed to investigate the associations between sleep duration and brain morphology in typically developing children, and the moderating effect of subjective sleepiness in these associations.

Methods

In 81 children (45 boys, 10.53 years old), actigraphy-derived estimates of sleep duration were obtained over 5-7 days, and subjective daytime sleepiness wa
