Characteristics of adult male and female firearm suicide decedents: findings from the National Violent Death Reporting System.

OBJECTIVE To examine the risk factors and precipitating circumstances associated with firearm suicide. METHODS Data from the restricted National Violent Death Reporting System (2003-6) for 25 491 male and female suicide decedents aged 18 and older were analysed by multiple logistic regression to estimate the relative odds of firearm use with 95% CIs. RESULTS Firearms were often used in male (58.1%) and female (31.2%) suicides. Among male decedents, older age, veteran status, residing in areas with higher rates of firearm availability, raised blood alcohol concentration, acute crisis and relationship problems were all associated with firearm use. Conversely, men with a diagnosis of a mental health problem, a history of suicide attempts or alcohol problems had lower odds of firearm use. Among female decedents, factors with a significant effect on firearm use included: being older, married, white and a veteran; residing in areas with higher rates of firearm availability; having an acute crisis; having experienced the death of a relative or friend; being depressed; and having relationship problems. Of note, women who had a treated DSM-IV-diagnosed problem, previous suicide attempts and physical health problems were less likely to use firearms. CONCLUSIONS These findings challenge the conventional view that those who are severely depressed and suicidal are prone to highly lethal methods, such as firearms. Rather, firearms users may be reacting to acute situations.
