Late and Instable Sleep Phasing is Associated With Irregular Eating Patterns in Eating Disorders.

ABSTRACT:

Background

Sleep problems are common in eating disorders (EDs).

Purpose

We evaluated whether sleep-phasing regularity associates with the regularity of daily eating events.

Methods

ED patients (n = 29) completed hourly charts of mood and eating occasions for 2 weeks. Locomotor activity was recorded continuously by wrist actigraphy for a minimum of 10 days, and sleep was calculated based on periods of inactivity. We computed the center of daily inactivity (CenDI) as a measure of sleep phasing and consolidation of the daily inactivity (ConDI) as a measure of daily sleep rhythm strength. We assessed interday irregularities in the temporal structure of food intake using the standard deviation (SD) of frequency (IFRQ), timing (ITIM), and interval (IINT) of food intake. A s
