Abstract

Older adults self-regulate their driving as it becomes more challenging. This study evaluated physical performance and frailty to see their impact on strategic self-regulation in older drivers. The AAA Longitudinal Research on Aging Drivers study was a multisite prospective cohort study. The Fried Frailty Phenotype (FFP) and the National Health and Aging Trends Study (NHATS) Short Physical Performance Battery (SPPB) were administered to 2990 older drivers. Mixed-effects Poisson regression models estimated strategic self-regulation associated with the SPPB and the FFP adjusting for age, sex, visual perception, cognition, miles driven, and urban/rural status. Compared to older drivers with good SPPB scores, strategic self-regulation increased 17% among those with fair scores and 38% among those with poor scores. Compared to older drivers who were not frail, strategic self-regulation increased 6% among pre-frail drivers and 26% among frail drivers. Strategic self-regulation increased in a dose-response relationship with both frailty and physical function.

老年人身体机能和虚弱对策略自我调节的纵向影响。

随着驾驶变得更具挑战性，老年人会自我调节自己的驾驶习惯。这项研究评估了身体表现和虚弱程度，以了解它们对老年司机战略自我调节的影响。美国汽车协会老年驾驶员纵向研究是一项多地点前瞻性队列研究。对2990名老年驾驶员进行了油炸脆性表型（FFP）和国家健康与老龄化趋势研究（NHATS）短物理性能电池（SPPB）测试。混合效应泊松回归模型估计了与SPPB和FFP相关的策略自我调节，调整了年龄、性别、视觉感知、认知、行驶里程和城乡状况。与SPPB得分较高的老年司机相比，得分一般的司机的策略自律能力提高了17%，得分较差的司机的策略自律能力提高了38%。与身体不虚弱的老年司机相比，身体虚弱的司机的战略自我监管增加了6%，身体虚弱的司机增加了26%。策略自我调节增加与虚弱和身体功能呈剂量-反应关系。

期刊介绍： The Journal of Applied Gerontology (JAG) is the official journal of the Southern Gerontological Society. It features articles that focus on research applications intended to improve the quality of life of older persons or to enhance our understanding of age-related issues that will eventually lead to such outcomes. We construe application broadly and encourage contributions across a range of applications toward those foci, including interventions, methodology, policy, and theory. Manuscripts from all disciplines represented in gerontology are welcome. Because the circulation and intended audience of JAG is global, contributions from international authors are encouraged.
