Poor sleep quality and sleep apnea are associated with higher resting energy expenditure in obese individuals with short sleep duration.

ABSTRACT:

Context

Epidemiological studies reported an inverse or U-shaped relationship between sleep duration and weight. The relationship between sleep and resting energy expenditure (REE) has not been well characterized.

Objective

The aim of the study was to determine the relationship between sleep, REE, and stress hormones.

Design and setting

We conducted a cross-sectional evaluation of a prospective cohort study at a tertiary referral research clinical center.

Subjects

Subjects included 126 obese individuals (30 males, 96 females; age, 40.5 ± 6.9 yr; body mass index, 38.6 ± 6.5 kg/m(2); sleep duration, 360 ± 50 min/night; and sleep efficiency, 79.5 ± 7.5%).

Main outcome measure(s)

REE and respiratory quotient (RQ) were assessed by indirect calorimetry. Sleep d
