On an average day in the USA more than 100 Americans die by suicide—half use firearms. Suicide rates overall and by firearms are higher, on average, in states where household firearm ownership is more common. In general this means in states where a greater proportion of the population lives in rural areas. The current ecological study focuses on the relation between measures of household firearm prevalence and suicide mortality in urban areas (metropolitan statistical areas and divisions) using… 

Differences in Firearm Suicides by Residential Location in Texas, 2006–2015

TLDR
Differences in firearm use rates by residential location likely reflect higher firearm ownership in smaller communities and rural than urban areas and underscore the importance of community- and individual-level suicide prevention strategies.

Prevalence of long gun use in Maryland firearm suicides

TLDR
Long guns are used in a large proportion of Maryland firearm suicides, particularly in rural areas and disproportionately in youth suicides, which must be considered as part of access to lethal means or policy strategies in efforts to reduce the burden of firearm suicide.

What Are We Aiming For? Comparing Suicide by Firearm in Toronto With the Five Largest Metropolitan Areas in the United States.

TLDR

Firearm Suicides in the Elderly: A Narrative Review and Call for Action

TLDR
Of all the strategies to prevent suicides with firearms, the most efficacious measures based on current research seem to be state firearm legislation and improving mental healthcare, but these effects are not specific to the elderly.

Suicide in American Cities

TLDR
The Zero Suicide Initiative aims to coordinate multi-level suicide prevention interventions across sites of healthcare, and may be particularly well-suited to urban areas, where sources of care are more densely available and healthcare contacts may be more frequent.

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

TLDR
The findings underscore the importance of designing gender- and age-specific policy advocacy programs directed at lowering the rate of firearm suicide, and suggest that California could serve as a model for other states starting preventive programs to reduce the firearm suicide rate.

Suicide by firearm in Switzerland: who uses the army weapon? Results from the national survey between 2000 and 2010.

TLDR
The hypotheses that the observed drop in suicides is linked to the Army XXI reform and that restriction of access to guns is essential for reducing suicides by firearm are supported.

Deadly Experience: The Association Between Firing a Gun and Various Aspects of Suicide Risk

TLDR
It is indicated that guns may confer risk of suicide in part through increased comfort and aptitude with the weapon, a notion consistent with the construct of practical capability.

Household Firearm Ownership and Suicide Rates in the United States

TLDR
In both regional and state-level analyses, a robust association exists between levels of household firearm ownership and suicide rates and where firearm ownership levels are higher, a disproportionately large number of people die from suicide.

Firearms and suicide in the northeast.

TLDR
Firearm prevalence was positively related to the suicide rate, even after controlling for rates of attempted suicide, and could not be accounted for by differences in method-specific case fatality rates.

Household firearm ownership and rates of suicide across the 50 United States.

TLDR
Household firearm ownership levels are strongly associated with higher rates of suicide, consistent with the hypothesis that the availability of lethal means increases the rate of completed suicide.

Access to firearms and risk for suicide in middle-aged and older adults.

TLDR
Among subjects who kept a gun in the home, storing the weapon loaded and unlocked were independent predictors of suicide, and support the potential benefit for suicide prevention of restricting access to handguns.

Firearm availability and suicide, homicide, and unintentional firearm deaths among women

TLDR
The elevated rates of violent death in states with more guns was not entirely explained by a state’s poverty or urbanization and was driven primarily by lethal firearm violence, not by lethal nonfirearm violence.

Homicide and suicide risks associated with firearms in the home: a national case-control study.

TLDR
Having a gun at home is a risk factor for adults to be shot fatally (gun homicide) or commit suicide with a firearm and Physicians should continue to discuss with patients the implications of keeping guns at home.

The presence and accessibility of firearms in the homes of adolescent suicides : a case-control study

TLDR
The availability of guns in the home, independent of firearms type or method of storage, appears to increase the risk for suicide among adolescents, and Physicians should make a clear and firm recommendation that firearms be removed from the homes of adolescents judged to be at suicidal risk.

TLDR
In United States regions with higher levels of household handgun ownership, there are higher suicide rates, and this relationship cannot be explained by differences in the prevalence of two mental health indicators—lifetime rates of either major depression or suicidal thoughts.

Suicide mortality in the United States: the importance of attending to method in understanding population-level disparities in the burden of suicide.

TLDR
Findings from ecologic and individual-level studies conducted over the past two decades illustrate the importance of accounting for the availability of highly lethal suicide methods in efforts to understand (and ultimately reduce) disparities in suicide mortality across populations.
