title: Sleep disorders in the adult population of Santiago of Chile and its association with common psychiatric disorders.
abstract: BACKGROUND
  Sleep disorders are a frequent problem and they are a usual reason of primary care consultation, because they cause a significant deterioration in the quality of life. Insomnia is the most common sleep disorder and it has a total prevalence in adults estimated of 19.1%, of whom 85% are chronic insomnia, which in turn is closely related to psychiatric disorders and even more it has been described as a depressive episode marker.
  
  
  OBJECTIVE
  To characterize the Santiago adult population suffering from sleep disorders and analyze their statistical association with common mental disorders.
  
  
  METHODS
  It corresponds to a secondary analysis of the survey “Common Mental Disorders in Santiago”. A cross-sectional survey that used as a sampling frame the adult population of Santiago aged between 16 to 64 years was carried out. A structured interview covering sociodemographic factors and the Revised Clinical Interview Schedule (CIS-R) to measure emotional symptoms, were applied.
  
  
  RESULTS
  3867 people representative of the adult population were evaluated (52.3% women, 47.7% men). The prevalence of sleep disorders was 26.3%. Sociodemographic risk factors, statistically significants, were detected like female gender, unemployed seeking employment, the presence of a common mental disorder, alcohol and drugs consumption in the last month, among others.
  
  
  CONCLUSIONS
  There is a high prevalence of sleep disorders among the population of Santiago; this is closely associated to female gender, social disadvantages and potently to the presence of a common mental disorder.
