The Association between Firearm Control Policies and Firearm Suicide among Men: A State-Level Age-Stratified Analysis

This study examined the association between state-specific firearm control policies and firearm suicide rates among men after adjusting for state-level demographics. This cross-sectional study used state-level mortality data from the Centers for Disease Control and Prevention's Web-based Injury Statistics Query and Reporting System and the Brady Campaign State Scorecard in 2017. An age-stratified (15-24 years, 25-44 years, 45-64 years, and ≥ 65 years) multivariable analysis was conducted to identify gun control policies that are associated with firearm suicide rates among men in each age group. Results indicate that the associations of specific firearm control policies and firearm suicide rates differ across the age span. In particular, more policies (for example, dealer regulations and waiting periods) are negatively associated with firearm suicide rate among men 15 to 24 years of age. The findings underscore the importance of designing gender- and age-specific policy advocacy programs directed at lowering the rate of firearm suicide. This study also suggests that California, known for its innovative gun safety legislation efforts, could serve as a model for other states starting preventive programs to reduce the firearm suicide rate. Implications of the findings for social work practice are discussed.
