Is There an Association Between Self-Reported Physical Activity and Self-Rated Vision Over Time? Results From the Irish Longitudinal Study of Ageing.

Research suggests that physical activity (PA) has many health benefits for an aging population. Evidence exploring the association between PA and vision is limited. This study includes the measures of self-reported PA (International Physical Activity Questionnaire) and self-rated vision at three points in time over a 6-year period used in the Irish Longitudinal study of Ageing, a cohort of community-dwelling older adults (50 years or older). A path analysis found that PA was indirectly associated with vision over 6 years controlling for age, sex, marital status, employment, education, depression (Centre for Epidemiologic Studies Depression Scale), self-reported general health, cardiovascular disease (e.g., heart attack), high blood pressure, diabetes, eye disease (e.g., glaucoma, diabetic eye disease, macular degeneration, cataract), and disabilities associated with activities of daily living. Further research is needed to fully understand the relationship over time and generalize the findings. [ABSTRACT FROM AUTHOR]
