Sleep cyclic alternating pattern in otherwise healthy overweight school-age children.

ABSTRACT:

Study objectives

To compare sleep microstructure (cyclic alternating pattern, CAP) characteristics in otherwise healthy overweight (OW) and normal weight (NW) children.

Design

Polysomnographic cross-sectional study.

Setting

Sleep laboratory.

Participants

Fifty-eight (26 NW and 32 OW) 10-year-old children.

Interventions

N/A.
