Abstract

Background: To assess the relationship between self-reported and performance-based visual impairment (VI) and lower extremity physical function.

Methods: Cross-sectional analysis of 2 219 Health ABC participants who completed vision testing and the Short Physical Performance Battery (SPPB). Linear regression models used either self-reported (weighted visual function question [VFQ] score) or performance-based (visual acuity [VA], log contrast sensitivity [LCS], Frisby stereoacuity [SA]) to predict SPPB or its components-gait speed, chair stands, or standing balance-with and without covariate adjustment.

Results: Mean age was 73.5 years (range 69-80); 52.4% were female and 37.4% African American. All VI measures were strongly associated with SPPB in unadjusted and adjusted models (p < .001). A self-reported VFQ score 1 standard deviation lower than the mean (mean 87.8 out of 100) demonstrated a -0.241 (95% confidence interval [CI]: -0.325, -0.156) adjusted difference in SPPB. After controlling for covariates, VA of <20/40 (41%) demonstrated a -0.496 (-0.660, -0.331) lower SPPB score while SA score>85 arcsec (30%) had a -0.449 (-0.627, -0.271) adjusted SPPB score versus those with better visual function. LCS < 1.55 (28.6%) was associated with a -0.759 (-0.938, -0.579) lower and LCS ≤ 1.30 (8%) with a -1.216 (-1.515, -0.918) lower adjusted SPPB score relative to better LCS. In a final multivariable model containing multiple vision measures, LCS remained independently associated with SPPB and all components, while SA remained associated with balance (all p < .05).

Conclusions: Both self-reported and performance-based VI are strongly associated with poor lower extremity physical function. These findings may identify a subgroup of older adults with co-existing visual and physical dysfunction who may benefit from targeted screening and intervention to prevent disability.

自我报告和基于表现的视觉功能与基于表现的身体功能测量的关系:健康ABC研究。
背景:评估自我报告和基于表现的视觉障碍(VI)与下肢身体功能之间的关系。方法:对2219名完成视力测试和短期体能测试(SPPB)的健康ABC参与者进行横断面分析。线性回归模型使用自我报告(加权视觉功能问题(VFQ)评分)或基于绩效的(视力(VA)、对数对比敏感度(LCS)、弗里斯比立体视力(SA))来预测SPPB或其组成部分步态速度、椅子站立或站立平衡(有无协变量调整)。结果:平均年龄73.5岁(69-80岁);52.4%为女性,37.4%为非裔美国人。在未调整和调整的模型中,所有VI测量都与SPPB密切相关(p85 arcsec(30%)与视觉功能较好的模型相比,调整后的SPPB得分为-0.449(-0.627,-0.271)。LCS结论:自我报告和基于表现的VI都与下肢身体功能差密切相关。这些发现可能会确定一组同时存在视觉和身体功能障碍的老年人,他们可能受益于有针对性的筛查和干预,以预防残疾。
