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.

A mixed-methods examination of fixed-object crashes among electric utility company fleet vehicles.

Introduction: One of the most common and serious types of crashes among all motor-vehicle users involves collisions with fixed objects. This type of crash occurs frequently among utility vehicle workers while driving for work. The overarching objective of this research was to improve the safety of electric utility company vehicle operators by determining the circumstances under which utility vehicles are involved in crashes with fixed objects and to provide recommendations to help drivers and utility fleet company management prevent these types of crashes.

Prevalence of Depression in Older Adults and the Potential Protective Role of Volunteering: Findings From the LongROAD Study.

Background: As the US population continues to age, depression and other mental health issues have become a significant challenge for healthy aging. Few studies, however, have examined the prevalence of depression in community-dwelling older adults in the United States.

Methods: Baseline data from the Longitudinal Research on Aging Drivers study were analyzed to examine the prevalence and correlates of depression in a multisite sample of community-dwelling adults aged 65-79 years who were enrolled and assessed between July 2015 and March 2017.

Dietary supplement use is common in older adult drivers: an analysis from the AAA LongROAD study.

Background: Dietary supplement (DS) use is common and increasing among older adults, though much data available on use frequencies are from surveys and performed cross-sectionally. This paper sought to assess the frequency and pattern of dietary supplement use among older adults over time.

Methods: A secondary analysis of data from the AAA LongROAD study, a longitudinal prospective cohort study of older adult drivers, using data from baseline and the first two years of follow up included a total of 2990 drivers aged 65-79 years recruited at five study sites across the US from July 2015 to March 2017.

Diabetes mellitus and hard braking events in older adult drivers.

Background: Diabetes mellitus (DM) can impair driving safety due to hypoglycemia, hyperglycemia, diabetic peripheral neuropathy, and diabetic eye diseases. However, few studies have examined the association between DM and driving safety in older adults based on naturalistic driving data.

Methods: Data for this study came from a multisite naturalistic driving study of drivers aged 65-79 years at baseline.
