The life circumstances associated with a preference of using a firearm for suicide differ by sex and by age, according to a recent study. Researchers used suicide deaths from the National Violent Death Reporting System from 2003-2011 in 17 US states to assess the difference in the relation between 6 life circumstances and risk of firearm vs non-firearm suicides across sex and age groups. Mixed effect logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals. They found:
- The risk of using a firearm as compared to other means for suicide were greater among white, male, non-Hispanic, older (aged >50 years), and currently married US residents.
- Among all age and sex groups, the odds of firearm use were 21-29% greater in the presence of a recent crisis.
- Having a financial problem was significantly associated with firearm use among younger men, younger women, and older women, while physical health issues were associated with risk of firearm suicide among older men.
