title: Suicidal ideation in Chinese patients with chronic obstructive pulmonary disease: a controlled study.
abstract: BACKGROUND
  No study has been published on the prevalence of suicidal behaviour in older Chinese patients with chronic obstructive pulmonary disease (COPD). This study examined the 1-year prevalence of suicidal ideation in older Chinese COPD patients and explored its demographic and clinical correlates.
  
  
  METHODS
  A consecutive sample of 143 COPD patients and 211 matched control subjects were recruited and interviewed using structured, standardized instruments.
  
  
  RESULTS
  The 1-year prevalence of suicidal ideation in COPD patients and controls were 15.4% and 10.9%, respectively. In multivariate analyses, suicidal ideation was significantly associated with the severity of depressive symptoms in COPD patients.
  
  
  CONCLUSIONS
  Suicidal ideation was not higher in COPD patients than in controls.
