Suicidal behavior and firearm access: results from the second injury control and risk survey.

The association between home firearms and the likelihood and nature of suicidal thoughts and plans was examined using the Second Injury Control and Risk Survey, a 2001-2003 representative telephone survey of U.S. households. Of 9,483 respondents, 7.4% reported past-year suicidal thoughts, 21.3% with a plan. Similar proportions of those with and without a home firearm reported suicidal thoughts, plans, and attempts. Among respondents with suicidal plans, the odds of reporting a plan involving a firearm were over seven times greater among those with firearms at home, compared with those without firearms at home. The results suggest people with home firearms may not be more likely to be suicidal, but when suicidal they may be more likely to plan suicide by firearm.
