title: [Tobacco smoking and mental health].
abstract: BACKGROUND
  Smoking continues to be one of the most important health burdens worldwide.
  
  
  OBJECTIVE
  To describe smoking habits and associated risk factors in the population of Santiago, Chile.
  
  
  METHODS
  A cross sectional study of a representative sample of the population, from 16 to 64 years old, residents of Santiago, Chile (total population: 3,237,286). A structured interview that included questions about use of tobacco, the CIS-R interviews, used for common mental disorders, were applied.
  
  
  RESULTS
  From the sample of 4,693 households, 3,870 people were interviewed (52.2% women, 47.8% men) and 10% refused. Forty percent of the population currently smoked (52.5% men, 47.8% women). "Being a current smoker" was associated with being younger than 55, male sex, and having a common mental disorder.
  
  
  CONCLUSIONS
  Smoking is highly prevalent in Chile, as compared with developed countries and with some developing countries. Gender differences in use of tobacco have decreased. A higher risk of smoking for people with mental disorders is confirmed.
