To quantify the proportion of current US gun owners who are new to owning firearms and compare new versus long-standing gun owners with respect to their firearms and firearm-related behaviors.
We performed a cross-sectional analysis of a nationally representative probability-based online survey conducted in 2015 in the United States. We defined new gun owners as current firearm owners who acquired all of their firearms within the past 5 years, but who lived in a home without a gun at some time over the past 5 years. We defined long-standing firearm owners as all other current gun owners.
New gun owners represented 10% of all current US adult gun owners. In addition to being younger than long-standing gun owners, new gun owners were more likely to be liberal, own fewer guns, own handguns, own guns only for protection, and store guns in a safe manner.
Gun ownership is dynamic, with approximately 1 million Americans becoming new gun owners each year. Public Health Implications. Clinical guidelines should be updated to explicitly endorse re-evaluating household firearm status at regular intervals.
量化目前美国枪支拥有者中新拥有枪支的比例,并比较新拥有枪支者和长期拥有枪支者在枪支和与枪支相关的行为方面的差异。
我们对 2015 年在美国进行的一项具有全国代表性的基于概率的在线调查进行了横断面分析。我们将新枪支拥有者定义为在过去 5 年内获得所有枪支但在过去 5 年内曾在某个时间居住在没有枪支的家中的当前枪支拥有者。我们将长期枪支拥有者定义为所有其他当前枪支拥有者。
新枪支拥有者占所有当前美国成年枪支拥有者的 10%。除了比长期枪支拥有者年轻外,新枪支拥有者更有可能持自由派观点,拥有较少的枪支,拥有手枪,仅出于保护目的拥有枪支,并以安全的方式储存枪支。
枪支拥有是动态的,每年约有 100 万美国人成为新的枪支拥有者。公共卫生意义。临床指南应进行更新,明确支持定期重新评估家庭枪支状况。
