To drive or not to drive: The influence of social factors on the decisions of elderly drivers

Being able to drive is considered to be an important, if not vital, component of mobility in many jurisdictions. From a large population-based health survey, carried out in Ontario, Canada in 1990 it is estimated that 37.5% of the population aged 80 or older drives a motor vehicle at least once a year. Data from the survey have been used to make comparisons of drivers and non-drivers: people who drive are more likely to be male, to be married and to report no more than one chronic disease. People who do not drive are more likely to live in larger households and to report two or more chronic diseases. Although many of these factors are clearly related to one another, they exert independent associations with whether people drive after other factors have been controlled. Drivers and non-drivers have similar frequency of contact with family and friends after other variables have been controlled for. (C) 1998 Elsevier Science Ltd. All rights reserved.
