- Abstract
<bold>Background: </bold>Older people are at greater risk of traffic accidents, partially because of age-related declines in visual function, including reduced useful field of view (UFOV). However, lifestyle factors which cause age-related decline in UFOV remain poorly understood. We conducted a study to investigate whether physical activity and appetite status were related to UFOV test performance in healthy older adults.<bold>Methods: </bold>Thirty community-dwelling older people (age 68.6 ± 3.1 years, 15 females) were enrolled in this study. Each participant completed the Council on Nutrition appetite questionnaire (CNAQ) and a UFOV test. They then wore a tri-axial accelerometer (Active style Pro HJA-350IT) for 3-6 consecutive days to objectively measure their PA in free-living conditions.<bold>Results: </bold>Longer time spent in vigorous physical activity was significantly associated with better UFOV test performance when adjusted for age and accelerometer wear time (non-locomotive: r = -0.435, locomotive: r = -0.449; n = 25). In addition, male, but not female, participants with a higher CNAQ score had significantly better UFOV test performance in both an unadjusted model (r = -0.560; n = 15) and a model adjusted for age (r = -0.635; n = 15).<bold>Conclusions: </bold>The results suggest that appetite status among males and time spent in high intensity PA are associated with visual function related to driving competence in older adults.
