title: The prevalence and clinical features of the night eating syndrome in psychiatric out-patient population.
abstract: OBJECTIVE
  In this study we aimed to investigate the prevalance and clinical correlations of night eating syndrome (NES) in a sample of psychiatric outpatients.
  
  
  METHODS
  Four hundred thirthy three consecutive psychiatric out-patients older than 18years were evaluated in the outpatient clinics using clinical interview according to the DSM-IV with regard to psychiatric diagnosis. Participants were also screened for presence of NES utilizing both clinical interview and self report based on Night Eating Questionnaire (NEQ) instruments. Sociodemographic and clinical features such as age, gender, education level, socioeconomic level and body mass index (BMI) were also recorded. The Body Shape Questionnaire (BSQ) and the Symptom Checklist-90 Revised (SCL-90R) were administered.
  
  
  RESULTS
  Based on the proposed diagnostic criteria of the NES via utilizing clinical interview method, 97 (32 male, 65 female) of the sample met diagnostic criteria for NES. The point prevalence of NES was 22.4%. No statistically significant differences were found between the two groups in terms of age, gender, marital status, education and BMI. The patients with NES had higher NEQ, BSQ and SCL-90R subscale scores than patients without NES. Prevalance of depressive disorder, impulse control disorder, and nicotine dependency was higher among patients with NES. No differences were found with regard to the medication (antipsychotics, antidepressants and mood stabilizers).
  
  
  CONCLUSIONS
  Night eating syndrome is prevalent among psychiatric outpatients and associated with depression, impulse control disorder, and nicotine dependency. Body dissatisfaction and higher symptom severity are also other risk factors for the development of NES.
