title: Comorbid psychiatric diagnoses in suicide attempt by charcoal burning: a 10-year study in a general hospital in Taiwan.
abstract: OBJECTIVE
  Over the last decade, charcoal burning has become a common method of suicide in Taiwan; however, the underlying psychiatric diagnoses and gender differences have yet to be examined.
  
  
  METHODS
  We conducted a retrospective chart review on inpatients after suicide attempt by charcoal burning during 2000-2010. The patients were referred to the psychiatric consultation team and diagnoses were made according to DSM-IV. We chose those who were admitted to the nephrology ward in the same period due to accidental carbon monoxide intoxication as controls. Demographic and laboratory data, psychiatric diagnoses and reasons for suicide were obtained and analyzed.
  
  
  RESULTS
  Among seventy-three patients, major depressive disorder (49.3%) and adjustment disorder (41.1%) were most frequently diagnosed. Breaking-up, financial debt and physical/mental illnesses were the top three reasons for suicide (17.8% each). The male-to-female gender ratio was 1.5:1. Female patients had higher rates of major depressive disorders, while male patients presented more adjustment disorders comorbid with alcohol use disorders.
  
  
  CONCLUSIONS
  There were gender differences in patients of suicide attempt by charcoal burning, in terms of demographic profiles and psychiatric diagnoses. Suicide risk assessment and prevention should be tailored by gender.
