Men were eight times as likely to kill themselves by gunshot than non-owners. Women were 35 times as likely.
The NYTimes reported:
The study, posted by The New England Journal of Medicine, does not greatly alter the prevailing understanding of suicide risk linked to gun ownership. Previous research had suggested a similarly increased risk, due largely to the ease of having such a lethal option at hand.
But experts said the new evidence was more powerfully persuasive than any research to date. The study tracked nearly 700,000 first-time handgun buyers, year by year, and compared them with similar non-owners, breaking out risk by gender. Men who bought a gun for the first time were eight times as likely to kill themselves by gunshot in the subsequent 12 years than non-owners; women were 35 times as likely to do so. (Male gun owners far outnumbered women owners in the study.)
