背景：火器拥有权常常被用来衡量获得武器的情况。然而，谁拥有枪支的人可能无法获得它，相反，谁不拥有枪支的人可能能够访问一个quickly.Objectives：要检查是否使用枪支所有权是一个合理的代理访问通过描述与所有权和access.Methods相关的人口特征：数据是从1994年伤害控制和风险调查，一个全国性的，随机数字拨号调查。收集了关于家庭枪支所有权和随时可获得已上膛枪支的信息，并进行了加权，以提供国家估计数。调整后的优势比为三个独立的模型进行了计算，使用logistic regression.Results：共有1353（27.9%）的受访者报告都有一个枪支在家庭中，并准备进入一个。另有313名受访者（8.1%）报告拥有枪支，但无法获得这些武器。另有421名受访者（7.2%）在家中或周围没有枪支，但报告能够在10分钟内取回并射击。根据逻辑回归结果，后一组的人口特征与那些报告所有权的人有很大不同。那些谁没有枪支，但报告随时可以获得一个，更有可能是少数民族，单身，并生活在附加homes.Conclusions：只问有关枪支的存在，在一个家庭可能会错过一些受访者随时可以获得一个加载的枪支。更重要的是，那些不拥有枪支，但报告随时可以获得枪支的人似乎与那些报告拥有枪支的人有质的不同。在使用所有权措施作为获取的替代时，应谨慎行事。
Background: Firearm ownership has often been used to measure access to weapons. However, persons who own a firearm may not have access to it and conversely, persons who do not own a firearm may be able to access one quickly.Objectives: To examine whether using firearm ownership is a reasonable proxy for access by describing the demographic characteristics associated with ownership and access.Methods: Data are from the 1994 Injury Control and Risk Survey, a national, random digit dial survey. Information about household firearm ownership and ready access to a loaded firearm were collected and weighted to provide national estimates. Adjusted odds ratios for three separate models were calculated using logistic regression.Results: A total of 1353 (27.9%) respondents reported both having a firearm in the household and ready access to one. An additional 313 respondents (8.1%) reported having a firearm, but were not able to access these weapons. Another 421 respondents (7.2%) did not have a firearm in or around their home, yet reported being able to retrieve and fire one within 10 minutes. Based on the logistic regression findings, the demographic characteristics of this latter group are quite different from those who report ownership. Those who do not have a firearm, but report ready access to one, are more likely to be ethnic minorities, single, and living in attached homes.Conclusions: Asking only about the presence of a firearm in a household may miss some respondents with ready access to a loaded firearm. More importantly, those who do not own a firearm, but report ready access to one, appear to be qualitatively different from those who report ownership. Caution should be exercised when using measures of ownership as a proxy for access.
