Results show that 74.8 percent of participants were poor sleepers, and their mean self-reported sleep duration was only six hours and 20 minutes.
Fifty-two percent of study subjects were anxious, and 43 percent were depressed. After controlling for age, sex, hypertension, diabetes, and obstructive sleep apnea, sleep quality and daytime sleepiness were significantly associated with mood disturbance and quality of life impairment.
"There was a clear association between the sleep problems such as short sleep duration and the psychological disorders and with quality of life," Dr. G. Neil Thomas, from the University of Birmingham in the United Kingdom, said. "These associations remained significant even after adjusting for a range of potential confounders."
According to the authors, the potential role of sleep in the health and well-being of individuals with severe obesity is underappreciated. The results suggested that the early detection of disturbed sleep could prevent the potential development and perpetuation of psychological problems among people with extreme obesity.
The study was published in the journal Sleep.
