The Longitudinal Association of Physical Function and Frailty on Driving Strategic Self-Regulation Among Older Adults.
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.
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.
