title: Suicidal ideation and suicide attempts in general medical illnesses.
abstract: BACKGROUND
  This study examines the association between the presence of a general medical illness and suicidality in a representative sample of US young adults.
  
  
  METHODS
  Between 1988 and 1994, 7589 individuals aged 17 to 39 years were administered the Diagnostic Interview Schedule as part of a national probability survey. The survey collected information about lifetime suicidal ideation and suicide attempts, a checklist of common general medical conditions, and data on major depression, alcohol use, and demographic characteristics.
  
  
  RESULTS
  Whereas 16.3% of respondents described suicidal ideation at some point in their lives, 25.2% of individuals with a general medical condition, and 35.0% of those with 2 or more medical illnesses reported life-time suicidal ideation. Similarly, whereas 5.5% of respondents had made a suicide attempt, 8.9% of those with a general medical illness and 16.2% of those with 2 or more medical conditions had attempted suicide. In models controlling for major depression, depressive symptoms, alcohol use, and demographic characteristics, presence of a general medical condition predicted a 1.3 times increase in likelihood of suicidal ideation; more specifically, pulmonary diseases (asthma, bronchitis) were associated with a two-thirds increase in the odds of lifetime suicidal ideation. Cancer and asthma were each associated with a more than 4-fold increase in the likelihood of a suicide attempt.
  
  
  CONCLUSIONS
  A significant association was found between medical conditions and suicidality that persisted after adjusting for depressive illness and alcohol use. The findings support the need to screen for suicidality in general medical settings, over and above use of general depression instruments.
