title: Risk factors of suicide attempts by poisoning: review.
abstract: BACKGROUND
  Suicide, a complex and universal human phenomenon, is a major public health problem. This study reviewed the literature about the major risk factors associated with suicide attempts by poisoning.
  
  
  METHODS
  An integrative review of the literature was performed in databases (LILACS, PubMed and MEDLINE) to search for studies published between 2003 and 2013, using the following keywords: suicide, attempted; poisoning; risk factors. Inclusion criteria were: original study with abstract, sample of adults, and attempted suicide by poisoning in at least 50% of the study population.
  
  
  RESULTS
  Two hundred and nineteen studies were retrieved and read by two independent examiners, and 22 were included in the study. The main risk factors for suicide attempts by poisoning were female sex, age 15-40 years, single status, little education, unemployment, drug or alcohol abuse or addiction, psychiatric disorder and psychiatric treatment using antidepressants.
  
  
  CONCLUSIONS
  Further prospective studies should be conducted to confirm these risk factors or identify others, and their findings should contribute to planning measures to prevent suicide attempts.
