Table_1_Associations of Self-Care Health Behaviors With Driving Cessation Among Older Drivers.DOCX

Older adults are at risk of driving cessation as they age, which can result in negative health outcomes including loss of independence. This study aimed to investigate the associations of self-care health behaviors with the risk of driving cessation. Demographics, health and driving characteristics were captured from healthcare systems in Denver, CO, San Diego, CA, Ann Arbor, MI, Baltimore, MD and Cooperstown, NY for 2,990 adults at baseline then followed from July 2015 to January 2021 via in-person assessments and questionnaires. The follow-up accumulated a total of 7,348 person-years and 46 driving cessations, yielding an incidence rate of 0.63 per 100 person-years. Multivariable Cox proportional hazards regression was used to evaluate the relationship between self-care behaviors and driving cessation, stratified by gender, and accounting for multiple failure events and clustering by study site. Ability to participate in social roles and activities was associated with an 8% reduction in the risk of driving cessation [adjusted hazard ratio (HR): 0.92; 95% CI: 0.89, 0.94]. Increased participation in social activities and relationships is associated with driving longevity in older adults and should be targeted for interventions to maintain driving mobility.

随着年龄的增长，老年人群面临着驾驶终止的风险，这可能导致包括独立性的丧失在内的负面健康后果。本研究旨在探讨自我照护健康行为与驾驶终止风险之间的关联。研究人员从科罗拉多州的丹佛、加利福尼亚州的圣地亚哥、密歇根州的安阿伯、马里兰州的巴尔的摩以及纽约州的库珀斯敦的医疗保健系统中收集了2,990名成年人的人口统计学、健康状况和驾驶特征数据，并在基线时进行了记录。随后，从2015年7月到2021年1月，通过面对面评估和问卷的方式对参与者进行了追踪研究。追踪研究累积了总计7,348人年，并记录了46起驾驶终止事件，发病率为每100人年0.63。通过多变量Cox比例风险回归模型，评估了自我照护行为与驾驶终止之间的关联，并根据性别进行了分层分析，同时考虑了多个失败事件和研究地点的聚类效应。参与社会角色和活动的能力与驾驶终止风险降低8%相关[调整后的风险比（HR）：0.92；95%置信区间：0.89, 0.94]。增加参与社会活动和人际关系与老年人群的驾驶长期性相关，应针对这些方面进行干预，以维持驾驶的移动性。
