Poor sleep linked to lower quality of life, increased moodiness in patients with obesity

Poor sleep quality is significantly associated with mood disturbance and lower quality of life among obese individuals, according to study data published in Sleep.

“Despite the very high levels of problems in these patients, those involved with their care usually don’t ask about sleep problems and often pay little heed to the psychological issues underlying obesity,” study researcher G. Neil Thomas, PhD, of the department of public health, epidemiology and biostatistics at the University of Birmingham, United Kingdom, said in a press release.

The study included 270 patients (mean age, 43.3 years; mean BMI, 46.9). More than half of the study participants were female. Sleep habits, anxiety, depression and quality of life were assessed using self-reported questionnaires.

Study participants’ answers showed that 74.8% were poor sleepers, 52% experienced anxiety and 43% were depressed. The mean amount of sleep participants received in a night was 6 hours, 20 minutes. Data analysis showed poor sleep quality and excessive daytime sleepiness were associated with mood disturbance and quality of life. After adjusting for age, gender, hypertension, diabetes and obstructive sleep apnea, sleep quality and daytime sleepiness were significantly associated with mood disturbance and quality-of-life impairment.

“Our findings suggest that routine screening for sleep disorders in these obese populations would be beneficial. The early detection of such problems could prevent the potential development and perpetuation of psychological disorders among these individuals that may affect their efforts to address their obesity,” study researcher Marzieh Hosseini Araghi, BSc, MPH, of the University of Birmingham, and colleagues concluded.
