本研究的目的是评估人口密度对交通事故后死亡率的影响。受试者是车辆碰撞后需要牵引的司机，NASS-GES在1994-1998年期间抽样。根据事故地点的人口（大于或小于25，000人）和驾驶员居住县的人口密度（使用邮政编码和人口普查数据）对案件进行分类。病例还按年龄、安全带使用和车速分类。加权分层调查数据的分析方法用于估计对死亡率的影响。在样本中共识别出190，721起具有指定碰撞地点的案例，其中93.7%的案例在碰撞地点有指定人群，94.1%可以与驾驶员的县数据联系起来。死亡率在人口少于25，000的地区较高，与司机所在县的人口密度成反比。年龄、安全带使用和车速也对死亡率有显著影响，但在控制了这些因素后，农村地区的影响仍然存在（O.R. 2.10，95% CI。1.62-2.73）。农村地区居民在交通事故中死亡的风险过高，部分可归因于事故后因素。(C)2003爱思唯尔科技有限公司版权所有。
The objective of this study was to evaluate the effect of population density on mortality after traffic crashes. Subjects were the drivers of vehicles requiring towing after collisions, sampled by NASS-GES during 1994-1998. Cases were classified by population of crash location (greater or lesser than 25,000) and by population density of the driver's county of residence (using ZIP code and Census data). Cases were also categorized by age, belt use and vehicle speed. Analytic methods for weighted, stratified survey data were used to estimate effects on mortality. A total of 190,721 cases with a specified crash location were identified in the sample, of which 93.7% had a specified population at the crash location, and 94.1% could be linked to the driver's county data. Mortality was higher in locations with populations less than 25,000 and was inversely proportional to the driver's county population density. Age, belt use, and vehicle speed also affected mortality significantly, but the effect of rural location remained after controlling for these factors (O.R. 2.10, 95% C.I. 1.62-2.73). The excess risk for residents of rural areas to die in traffic crashes can be attributed in part to post-crash factors. (C) 2003 Elsevier Science Ltd. All rights reserved.
