To assess the cross-sectional association between self-rated eyesight and physical activity behaviour in a large general population sample of older English adults.
Analyses of data from the English Longitudinal Study of Ageing. Participants provided information on self-rated eyesight (categorised as: excellent/very good/good/fair-poor) and their own physical activity levels (categorised as: inactive/moderate only at least 1/week, vigorous at least 1/week). Associations between self-rated eyesight and physical activity levels were examined using logistic regression.
A total of 6634 participants (mean age 65.0±9.2 years) were included in the analyses. In adjusted logistic regression models, those with fair-poor and good eyesight were significantly more likely to be inactive than those who reported excellent eyesight (OR 2.07, 95% CI 1.58 to 2.72; OR 1.59, 1.27 to 1.99, respectively).
In this sample of older English adults, those with self-rated fair-poor vision were over twice as likely to be physically inactive than those who reported having excellent vision. When consistent data have emerged, interventions to increase physical activity in those who have poor eyesight are needed.
在大量英国老年成年人的普通人群样本中评估自评视力与身体活动行为之间的横断面关联。
对英国老龄化纵向研究的数据进行分析。参与者提供了关于自评视力（分类为：优秀/非常好/良好/一般-差）和自身身体活动水平（分类为：不活动/仅中度活动每周至少1次/每周至少1次剧烈活动）的信息。使用逻辑回归分析自评视力与身体活动水平之间的关联。
共有6634名参与者（平均年龄65.0±9.2岁）纳入分析。在调整后的逻辑回归模型中，视力一般-差和良好的参与者比报告视力优秀的参与者显著更有可能不活动（分别为OR 2.07，95%CI 1.58至2.72；OR 1.59，1.27至1.99）。
在这个英国老年成年人样本中，自评视力一般-差的人身体不活动的可能性是报告视力优秀者的两倍多。当出现一致数据时，需要采取干预措施来增加视力差者的身体活动。
