Suicide Rates and State Laws Regulating Access and Exposure to Handguns

Category: Firearm Policies, Suicide|Journal: American Journal of Public Health (full text)|Author: J Anestis, M Anestis|Year: 2015

Objectives

Using previous research, we examined the impact of 4 handgun laws (waiting periods, universal background checks, gun locks, and open carrying regulations) on suicide rates.

Methods

We used publicly available databases to collect information on statewide laws, suicide rates, and demographic characteristics for 2013.

Results

Each law was associated with significantly lower firearm suicide rates and the proportion of suicides resulting from firearms. In addition, each law, except for that which required a waiting period, was associated with a lower overall suicide rate. Follow-up analyses showed a significant indirect effect on overall suicide rates through the proportion of suicides by firearms, indicating that the reduced overall suicide rate was attributable to fewer suicide attempts, fewer handguns in the home, suicide attempts using less lethal means, or a combination of these factors. States that implemented any of these laws saw a decreased suicide rate in subsequent years, whereas the only state that repealed 1 of these laws saw an increased suicide rate.

Conclusions

Our results were supportive of a potentially vital role in suicide prevention for state legislation that limits access and exposure to handguns.
