Trajectories of reported sleep duration associate with early childhood cognitive development.

ABSTRACT:

Study objectives

Examine how different trajectories of reported sleep duration associate with early childhood cognition.

Methods

Caregiver-reported sleep duration data (n = 330) were collected using the Brief Infant Sleep Questionnaire at 3, 6, 9, 12, 18, and 24 months and Children's Sleep Habits Questionnaire at 54 months. Multiple group-based day-, night-, and/or total sleep trajectories were derived-each differing in duration and variability. Bayley Scales of Infant and Toddler Development-III (Bayley-III) and the Kaufman Brief Intelligence Test- 2 (KBIT-2) were used to assess cognition at 24 and 54 months, respectively.

Results

Compared to short variable night sleep trajectory, long consistent night sleep trajectory was associated with higher scores on Bayley-III
