title: Characteristics of suicide attempters with family history of suicide attempt: a retrospective chart review.
abstract: BACKGROUND
  Family history of suicide attempt is one of the risks of suicide. We aimed at exploring the characteristics of Japanese suicide attempters with and without a family history of suicide attempt.
  
  
  METHODS
  Suicide attempters admitted to an urban emergency department from 2003 to 2008 were interviewed by two attending psychiatrists on items concerning family history of suicide attempt and other sociodemographic and clinical information. Subjects were divided into two groups based on the presence or absence of a family history of suicide attempt, and differences between the two groups were subsequently analyzed.
  
  
  RESULTS
  Out of the 469 suicide attempters, 70 (14.9%) had a family history of suicide attempt. A significantly higher rate of suicide motive connected with family relations (odds ratio 2.21, confidence interval 1.18-4.17, p < .05) as well as a significantly higher rate of deliberate self-harm (odds ratio 2.51, confidence interval 1.38-4.57, p < .05) were observed in patients with a family history of suicide compared to those without such history. No significant differences were observed in other items investigated.
  
  
  CONCLUSIONS
  The present study has revealed the characteristics of suicide attempters with a family history of suicide attempt. Further understanding of the situation of such individuals is expected to lead to better treatment provision and outcomes, and family function might be a suitable focus in their treatment.
