Background: In the United States, only motor vehicle crashes and cancer claim more lives among children than do firearms. This national study attempts to determine whether firearm prevalence is related to rates of unintentional firearm deaths, suicides, and homicides among children.
Methods: Pooled cross-sectional time-series data (1988-1997) were used to estimate the association between the rate of violent death among 5-14 year olds and four proxies of firearm availability, across states and regions.
Results: A statistically significant association exists between gun availability and the rates of unintentional firearm deaths, homicides, and suicides. The elevated rates of suicide and homicide among children living in states with more guns is not entirely explained by a state's poverty, education, or urbanization and is driven by lethal firearm violence, not by lethal non-firearm violence.
Conclusion: A disproportionately high number of 5-14 year olds died from suicide, homicide, and unintentional firearm deaths in states and regions where guns were more prevalent.
