An analysis of statewide data in California from 2004 to 2016 found that homicide rates for adults who live with handgun owners were twice as high compared to adults who did not. Among homicides occurring at home, adults were seven times more likely to die by homicide with a firearm at the hand of a spouse or intimate partner who owned a gun, with most of those victims being women. The findings are published in Annals of Internal Medicine.
One in three homes in the United States have at least one firearm. Firearm owners cite the protection of themselves and their family as the lead motivator for owning a gun, and three quarters of gun owners report feeling safer with a firearm in their home. Evidence from previous studies instead suggests that gun ownership increases rates of homicide in the home. However, these studies have been more limited in size and scope.
Researchers from Stanford University studied data gun purchasing and death records for more than 17.6 million California adults to estimate the association between living with a lawful handgun owner and risk for homicide victimization. The data revealed more than double the risk of homicide among the 595,448 adults living with handgun owners. The records showed that these elevated rates were driven largely by higher rates of homicide by firearm and two thirds of the people who lived with gun owners and faced these elevated risks were women. The authors also note that while a small minority of homicides occurring at home were perpetrated by strangers, adults living with gun owners did not experience these attacks at lower rates than adults living with nonowners.
In an accompanying editorial, Christine Laine, MD, MPH, editor in chief of Annals of Internal Medicine and Sue Bornstein, MD, chair-elect of the American College of Physicians’ (ACP) Board of Regents, argue that gun violence both inside and outside the home should be treated as an epidemic and tackled with a multifaceted approach. To combat this issue, the authors suggest advancing legislation to enable risk protection orders, establishing programs to address social factors, and enforcing strong consequences for companies and individuals who facilitate the misuse of firearms. ACP has long advocated for the public and policy makers to recognize gun violence as a public health issue. As such, ACP says doctors should play an active role in preventing gun violence by talking to patients at risk.
