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

摘要

A number of epidemiologic studies have reported an association between habitual short duration of sleep and obesity or diabetes. Either an inverse or U-shaped relationship between sleep duration and weight occurred, depending on the study. It is unclear whether chronic sleep deprivation and impaired sleep quality have a causal relationship with obesity, or whether they represent coincidental secular trends. The effect of chronic sleep deprivation on resting energy expenditure (REE) is not well characterized. It has been suggested that sleep deprivation through activation of the stress system and the sympathetic nervous system could lead to increased energy expenditure.
