BACKGROUND
There is an overwhelmingly high incidence of severe injuries caused by motor vehicle crashes (MVCs) among Aboriginal Canadians as compared with the general population.
METHODS
The authors obtained MVC data for a 3-year period, 2003-2005, from Saskatchewan Government Insurance (SGI) for collisions occurring on on-reserve roads (n = 1270) together with a randomly selected sample of MVCs from off-reserve roads (n = 1270) in Saskatchewan. They compared the collision characteristics using bivariate and multiple logistic regressions.
RESULTS
On-reserve MVCs were more likely to include multiple collisions and result in severe injuries than the off-reserve sample. A number of factors were significantly related to the increased risk of on-reserve collisions as compared with the reference group for each variable.
INTERPRETATION
Factors from all 3 levels (human, environmental, and vehicle factors) are associated with on-reserve MVCs.
背景
与普通人群相比，加拿大原住民因机动车事故（MVC）而导致重伤的发生率极高。
方法
作者从萨斯喀彻温省政府保险（SGI）获取了 2003 年至 2005 年为期 3 年的保护区道路碰撞事故数据（n=1270），以及萨斯喀彻温省非保护区道路碰撞事故的随机样本（n=1270）。他们使用双变量和多逻辑回归比较了碰撞特征。
结果
保护区内的 MVC 更有可能发生多次碰撞并导致重伤，而非保护区样本。与每个变量的参考组相比，许多因素与保护区碰撞的风险增加显著相关。
解释
来自所有 3 个层面（人为因素、环境因素和车辆因素）的因素都与保护区内的 MVC 相关。
