ObjectiveTo estimate the protective effect of storing firearms locked or unloaded, or both, on the risk of suicide by firearms among people with relatively low intention to die.Design And SettingCross sectional survey. The 1993 National Mortality Followback Survey of 22 957 deaths in the United States, representing 2.2 million people, conducted by the National Center for Health Statistics.ParticipantsDecedent's next of kin answered questions regarding various aspects of decedent's life to supplement information from death certificates.Main ResultsCompared with decedents who stored their firearm unlocked or loaded, those who stored their firearms locked or unloaded, or both, were less likely to commit suicide by firearms (locked: OR = 0.39, 95% CI = 0.24 to 0.66; unloaded OR = 0.30, 95% CI = 0.18 to 0.49).ConclusionsThis study further supports the utility of devices and practices intended to reduce the likelihood of unauthorised or impulsive use of firearms.
