Data from a US mortality follow-back survey were analyzed to determine whether having a firearm in the home increases the risk of a violent death in the home and whether risk varies by storage practice, type of gun, or number of guns in the home. Those persons with guns in the home were at greater risk than those without guns in the home of dying from a homicide in the home (adjusted odds ratio = 1.9, 95% confidence interval: 1.1, 3.4). They were also at greater risk of dying from a firearm homicide, but risk varied by age and whether the person was living with others at the time of death. The risk of dying from a suicide in the home was greater for males in homes with guns than for males without guns in the home (adjusted odds ratio = 10.4, 95% confidence interval: 5.8, 18.9). Persons with guns in the home were also more likely to have died from suicide committed with a firearm than from one committed by using a different method (adjusted odds ratio = 31.1, 95% confidence interval: 19.5, 49.6). Results show that regardless of storage practice, type of gun, or number of firearms in the home, having a gun in the home was associated with an increased risk of firearm homicide and firearm suicide in the home.
对美国死亡率随访调查的数据进行了分析，以确定家中有枪支是否会增加家中暴力死亡的风险，以及风险是否因枪支存放方式、枪支类型或家中枪支数量而异。家中有枪的人比家中无枪的人在家中死于他杀的风险更高（调整后的优势比=1.9，95%置信区间：1.1，3.4）。他们死于枪支他杀的风险也更高，但风险因年龄以及死亡时该人与他人是否同住而有所不同。家中有枪的男性在家中死于自杀的风险高于家中无枪的男性（调整后的优势比=10.4，95%置信区间：5.8，18.9）。家中有枪的人死于枪支自杀的可能性也高于死于其他方式自杀的可能性（调整后的优势比=31.1，95%置信区间：19.5，49.6）。结果表明，无论家中枪支的存放方式、类型或数量如何，家中有枪都与家中枪支他杀和枪支自杀风险增加相关。
