Entry to firearms is a known risk factor for suicide, however new analysis from the UC Davis Violence Prevention Analysis Program (VPRP) finds that, amongst handgun purchasers, these with a historical past of alcohol prices have greater than twice the danger of suicide. The study was revealed in Preventive Medication.
“We all know entry to firearms is a powerful threat issue for suicide. And we all know from prior research that substance use is a threat issue for suicide. However nobody has checked out whether or not substance use is related to elevated suicide threat amongst firearm homeowners,” mentioned Julia Schleimer, the lead creator of the examine and a analysis information analyst at VPRP. “This is a vital hole as a result of, for coverage and prevention efforts, we’d like proof on contributing components which can be related to elevated threat above and past entry to firearms alone.”
Total, the examine confirmed that handgun purchasers who had alcohol prices (with out drug prices) had greater than two occasions the danger of suicide in contrast with handgun purchasers with neither alcohol nor drug prices. The chance was best amongst those that had two or extra alcohol arrests or convictions, and people whose final alcohol cost was throughout the 12 months earlier than or the 2 years after a handgun buy.
Drug prices, nonetheless, didn’t appear to point an elevated stage of threat for suicide.
How researchers performed the examine
To find out whether or not there was an elevated threat of suicide for handgun purchasers with drug and alcohol prices and convictions, the researchers analyzed information for all the boys who legally bought a handgun in California throughout 2001 — 101,377 in whole. The examine targeted on males as a result of over 90% of the purchases that 12 months had been by males, and no ladies with substance use-related prices died by suicide.
The researchers used information from the California Division of Justice to see how lots of the males with authorized handgun purchases had alcohol- or drug-related prison prices relationship again to January 1, 1990, similar to an arrest for driving below the affect (DUI) or drug prices. They then checked information from the California Division of Public Well being to see how lots of the 2001 cohort had died by suicide by way of the interval ending December 31, 2015.
“One of many key findings of the examine is that more moderen and repeat alcohol prices had been related to the best threat of suicide, together with firearm suicide,” Schleimer mentioned.
Of the 101,377 males who legally bought a handgun in California in 2001, 594 died by suicide, virtually 90% of whom used a firearm. That interprets to a price of 42 suicides per 100,000 inhabitants. The suicide price amongst males within the U.S. is 21.5 per 100,000 population, in accordance with the Facilities for Illness Management.
Research findings may assist suicide mitigation efforts
Suicide is a significant public well being disaster in the US, leading to over 47,500 deaths in 2019. The variety of suicides outnumbers homicides by virtually two and a half occasions. Suicide is the tenth main explanation for loss of life in the US for all age teams. For people between the ages of 10 and 34, it’s the second main explanation for loss of life.

The brand new outcomes present that handgun homeowners with alcohol offenses might profit from lowering firearm entry or alcohol use.
“This examine helps us higher establish the populations at elevated threat of suicide, which may, in flip, inform scientific interventions, firearm coverage and substance use prevention and therapy efforts. For instance, clinicians would possibly counsel sufferers who’ve alcohol dependence and who personal firearms about threat discount methods like secure firearm storage and non permanent firearm switch,” Schleimer mentioned.
The bulk of people that survive a suicide try do not go on to die by suicide. Given the lethality of firearm suicide makes an attempt, limiting entry to firearms amongst these vulnerable to self-harm might save lives.
