A National Evaluation of the Impact of Child Access Prevention Laws on Rates of Youth Suicide and Other Youth Firearm Deaths.

Abstract

Objective: Rates of youth firearm injury deaths are precipitously increasing, in part because of increases in youth firearm suicides. State policies may reduce youth suicide and other firearm death rates by limiting access to firearms. We evaluated the impact of child access prevention (CAP) laws on rates of youth firearm suicide mortality. We evaluated whether CAP law associated changes in youth firearm suicide rates reflected shifts to non-firearm suicide methods or systematic changes in the classification of suicide deaths.

Method: We used nationally representative mortality data from 1990 through 2020. Data were disaggregated by state and year. CAP laws fall into two major categories: negligent storage of firearms policies that regulate how firearms are stored in households with children and reckless provision of a firearm to a minor policies that impose liability on firearm owners who provide youth with firearms that are used to harm others. Firearm suicide, non-firearm suicide, firearm homicide, firearm unintentional injury death rates among youth aged 1-17 were the main outcomes.

Results: Growth curve models revealed CAP firearm storage laws were associated with significant reductions in youth firearm suicide mortality. There was no evidence that these findings were the result of shifts in youth suicide methods or manner of death classifications. CAP firearm storage laws are a promising tool for reducing overall rates of youth suicide and youth firearm injury deaths.

Conclusion: CAP firearm storage policies appear to effectively reduce firearm suicide mortality, as well as firearm related unintentional injuries and homicide in youth.
