title: Gender differences with respect to psychiatric comorbidity in obstructive sleep apnea syndrome.
abstract: OBJECTIVE
  Psychiatric disorders are common in obstructive sleep apnea syndrome (OSAS); however, interrelating factors influencing psychiatric comorbidity (PC) in OSAS are unclear. The aim of this study is to investigate gender related differences with PC in OSAS.
  
  
  METHODS
  Data of patients diagnosed as OSAS in University of Gaziantep from January 2006 to January 2010 were retrospectively evaluated. Polysomnographic data were recorded with Viasys Sleep Screen (Viasys Healthcare, Germany). Patients younger than 18 years old were excluded.
  
  
  RESULTS
  PC was present in 53.1% of OSAS patients. The rate of male subjects with PC was 42.6%; however, 76.26% of females had PC (P = 0.00). Age (P = 0.00) and body mass index (BMI) (P = 0.00) were higher in patients with PC. Ferritin levels were lower in patients with PC (P = 0.00). Male subjects with PC were older and had lower sleep efficiency and longer rapid eye movement latency than males without PC. BMI was the only contributory factor to PC in female subjects.
  
  
  CONCLUSIONS
  PC in OSAS is common, especially in females. Apnea hypopnea index does not seem to influence probability of PC.
