Is car use related with successful aging of older adults? Results from the multinational Mediterranean islands study.

<bold>Purpose: </bold>The aim of the present work was to evaluate the relation between car use and the level of successful aging of a random sample of older adults living in the Mediterranean basin.<bold>Methods: </bold>During 2005-2011, 2749 older (aged 65-100 years) from 22 islands and the rural Mani region (Peloponnesus) of Greece were voluntarily enrolled in the Mediterranean islands cross-sectional study. Sociodemographics, medical conditions, and dietary and lifestyle habits were derived throughout standard procedures. Car use was recorded with a standard binary question. A successful aging index ranging from 0-10 was used.<bold>Results: </bold>Older adults who used a car on regular basis had significantly higher levels of successful aging, as well as less prevalence of obesity and hypertension while were more physically active (P < .001). After adjusting for several confounders car use was still positively related with elderly islander's successful aging level (beta coefficient [95% confidence interval]: 0.65 [0.54-0.77]).<bold>Conclusions: </bold>In conclusion, the activity of car use seems to be an indicator of quality of life among older adults, as measured through successful aging.
