A new study shows that poor sleep quality is strongly associated with mood disturbance and lower quality of life among people with extreme obesity. 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.
