Abstract
To evaluate the association between vision-related quality of life (QoL), physical inactivity, and locomotor dysfunction in subjects with visual impairment.This cross-sectional study included 215 visually impaired subjects recruited from six ophthalmology departments in Japan. The physical inactivity and locomotor dysfunction associated with their visual impairment was investigated. The physical activity level was assessed using the short form of the International Physical Activity Questionnaire and classified as high, moderate, or low. Locomotor function was evaluated with the Geriatric Locomotive Function Scale. Vision-related QoL was evaluated using the 25-item National Eye Institute Visual Function Questionnaire. Background data, including for age, sex, best-corrected visual acuity for each eye, causative eye diseases, systemic comorbidities, and body mass index, were also collected.The average patient age was 69.6 (range, 20–93 years; standard deviation, 14.5 years) and 118 patients (54.9%) were men. Multivariate analysis showed that vision-related QoL and best-corrected visual acuity in the worse eye were significantly associated with physical inactivity and that vision-related QoL, female sex, age, and presence of systemic comorbidity were significantly associated with locomotor dysfunction. Vision-related quality of life is associated with physical inactivity and locomotor dysfunction.
Highlights
Visual impairment is an increasingly prevalent public health problem, in aging populations
We found a significant association of vision-related quality of life (QoL) determined by the VFQ-25 score and best-corrected visual acuity (BCVA) in the worse eye with physical activity (IPAQ) in multivariate analysis
We found that BCVA in the better eye was not associated with the physical activity level or locomotor function
Summary
Visual impairment is an increasingly prevalent public health problem, in aging populations. Visually impaired older adults have difficulties with physical functioning[15,16], which increases the risk of falls and fractures[17,18,19,20,21,22,23]. In an aging society, such as that in Japan, locomotor dysfunction has a major impact on public health Compared with their sighted counterparts, blind children and adolescents have more sedentary lifestyles and lower levels of physical fitness[32,33]. There are no reports on the association between vision-related QoL and physical activity/locomotor function in adults with visual impairment.
