OBJECTIVES:Deaths from motor vehicle crashes (MVCs) have decreased significantly over the past three decades. Unfortunately, few data have been collected regarding death rates for MVCs in minority populations. The purpose of this study was to compare the death rate of whites versus Hispanics for MVCs in a rural environment. METHODS:This study examined one rural county in North Carolina from January 1, 1999, to December 31, 1999. A retrospective cohort study was performed using the North Carolina State Highway Patrol computerized database of MVCs. Data regarding the total number of MVCs, fatalities, alcohol-related deaths, seatbelt usage, and cause of the collision were analyzed for both whites and Hispanics. Census information regarding population in this region also was obtained from the U.S. Bureau of Census. Data were analyzed using a chi-square test, with an alpha value of 0.05 used to establish statistical significance. RESULTS:During the study period, whites were involved in 2,689 MVCs, compared with 158 MVCs for Hispanics. Whites were involved in ten fatal MVCs, compared with seven fatal MVCs involving Hispanics. The percent of fatal MVCs for whites was 0.3%, or 10 deaths per 2,689 MVCs. In contrast, the percent of fatal MVCs for Hispanics was 4.4%, or 7 deaths per 158 MVCs; odds ratio (OR) = 12.4, 95% CI = 4.7 to 33.1. The 2000 Census Report for Pitt County noted a white population of 81,613 and a Hispanic population of 4,216. Based on these population data, the death rate for MVCs per 100,000 population was 12.3 for whites versus 166.0 for Hispanics, OR = 13.6, 95% CI = 5.2 to 35.6. Although the cause for this disparity was not determined, previous studies suggest that alcohol and decreased seatbelt usage are contributing factors. CONCLUSIONS:In this study, the death rates among Hispanics for rural MVCs were significantly higher than for whites. The causes of this disparity are not clear but are important to define. Only by understanding this disparity can we begin to develop appropriate interventions that may prevent these deaths.

目标:在过去的三十年中,机动车事故造成的死亡人数显着减少。不幸的是,很少收集到有关少数族裔MVC死亡率的数据。本研究的目的是比较农村环境中MVC的白人与西班牙裔美国人的死亡率。
方法:本研究调查了1999年1月1日至1999年12月31日北卡罗来纳州的一个乡村县。使用北卡罗来纳州州高速公路巡逻的MVC计算机数据库进行了一项回顾性队列研究。分析了白人和西班牙裔的有关MVC总数,死亡人数,与酒精有关的死亡,安全带的使用以及撞车原因的数据。有关该区域人口的人口普查信息也可从美国人口普查局获得。使用卡方检验分析数据,α值为0.05,以建立统计显着性。
结果:在研究期间,白人参与了2689个MVC,而西班牙裔为158个。白人卷入了十次致命的MVC,而西班牙裔卷入了七次致命的MVC。白人的致命MVC百分比为0.3%,即每2689个MVC中有10例死亡。相比之下,西班牙裔致命MVC的百分比为4.4%,即每158个MVC中有7例死亡。比值比(OR)= 12.4,95%CI = 4.7至33.1。皮特县2000年人口普查报告指出,白人人口为81,613,西班牙裔人口为4,216。根据这些人口数据,白人每100,000人口MVC的死亡率为12.3,而西班牙裔为166.0,OR = 13.6,95%CI = 5.2至35.6。尽管尚未确定造成这种差异的原因,但先前的研究表明,酒精和安全带使用量的减少是造成这种情况的因素。
结论:在这项研究中,西班牙农村居民的MVC死亡率显着高于白人。造成这种差异的原因尚不清楚,但定义起来很重要。只有了解了这种差异,我们才能开始制定适当的干预措施,以预防这些死亡。
