There are approximately 42 million licensed drivers aged 65 years or older in the United States, who face unique age-related risks while driving. While physical activity affects several chronic conditions thought to be associated with motor vehicle crashes (MVCs), it is unclear if increased physical activity leads to fewer MVCs. This study explores whether self-reported vigorous and moderate physical activity is associated with MVCs in the previous year. Using cross-sectional data from the LongROAD study, a large multisite prospective cohort study of 2990 older adult drivers, we examined variables related to physical activity and performed a multivariate regression analysis to examine the association of physical activity health behaviors with self-reported MVCs. Overall, 41.2% of participants reported vigorous and 69.6% of participants reported moderate exercise at least once per week. Eleven percent of participants reported at least 1 MVC in the previous year. Neither vigorous nor moderate physical activity was significantly associated with self-reported MVCs in the previous year. Select variables that were significantly associated with self-reported MVC included self-reported unsafe driving practices (odds ratio [OR] 1.55, confidence interval [CI] 1.05-2.29), and fall in the past 12 months (OR 1.46, CI 1.14-1.85). We were unable to detect a significant association between self-reported physical activity and MVCs in the past year among this group of older drivers. Use of objective measures of activity may better clarify this relationship.
美国约有4200万名65岁及以上的持证司机，他们在驾驶时面临与年龄相关的独特风险。虽然体育活动会影响一些被认为与机动车碰撞事故（MVC）相关的慢性疾病，但尚不清楚增加体育活动是否会减少MVC。本研究探讨了自我报告的剧烈和适度体育活动与上一年的MVC之间是否存在关联。利用来自LongROAD研究的横断面数据，这是一项对2990名老年司机进行的大型多地点前瞻性队列研究，我们检查了与体育活动相关的变量，并进行了多元回归分析，以检验体育活动健康行为与自我报告的MVC之间的关联。总体而言，41.2%的参与者报告每周至少进行一次剧烈运动，69.6%的参与者报告每周至少进行一次适度运动。11%的参与者报告上一年至少发生过1次MVC。上一年，剧烈和适度的体育活动与自我报告的MVC均无显著关联。与自我报告的MVC显著相关的选定变量包括自我报告的不安全驾驶行为（比值比[OR]1.55，置信区间[CI]1.05 - 2.29），以及过去12个月内跌倒（OR 1.46，CI 1.14 - 1.85）。在这组老年司机中，我们未能检测到过去一年自我报告的体育活动与MVC之间存在显著关联。使用客观的活动测量方法可能会更好地阐明这种关系。
