Alimentary obesity has a strong comorbidity with sleep disorders. The aim of this research was to estimate the correlation
between insomnia and mental disorders among the obese patients.
Materials and Methods:
123 patients (51 males and 72 females, age 40.0?11.5; body mass index (BMI) 39.8?8.7 kg/m2) with
obesity were included in this study. Patients were divided in two groups: first group consisted from 55 patients with insomnia
complaints, second (controls)-68 patients without insomnia. Questionnaire survey of patients was conducted to check their
estimates of sleep quality. Psychological features were assessed with the Minnesota Multiphasic Personality Inventory (MMPI)
and Hospital Anxiety and Depression Scale (HADS). Mental disorders were diagnosed clinically according to ICD-10 criteria.
Subjective problems with quality of sleep were observed in 76%, snoring in 63%, hypersomnia symptoms in 55%,
features of sleep apnea in 50%, and insomnia signs in 45% of patients. Insomnia intensity significantly correlated (p<0.03) with
dysthymia and mild depressive episode. According to data of psychological testing, obese patients with insomnia had high levels
of health anxiety, somatization, depression, displacement and high susceptibility to mental stress. Mean levels of anxiety and
depression by HADS were significantly higher in patients with insomnia comparing ones without insomnia (8.8?4.4; 6.5?3.2
vs.7.3?2.8; 5.7?2.5, p<0.01). Patients of the first group more frequently had clinical anxiety and subclinical depression ("Chi-
square" (c2)=9.82; p<0.001 and c2=6.98; p<0.008 respectively). Clinically significant weight loss (5% or more of the initial) after
6 months of combined treatment was achieved more frequently in patients without insomnia comparing ones with insomnia
sleep disorders associated with latent or evident psychopathology affect the extent of weight loss in obese patients.
