Abstract

Purpose: Contrast sensitivity (CS), the ability to see objects against their background, is an important component of visual function. The effect of contrast sensitivity impairment (CSI) on physical functioning (PF) is not well documented. Methods: This study obtained data from the Aging, Demographics, and Memory Study. Baseline CS was measured, and self-reported PF, activities of daily living (ADLs), and instrumental activities of daily living (IADLs) were assessed biennially. Results: The sample included 263 individuals with a mean (SD) age: 82.1(5.3). Participants with severe CSI had PF limitation scores 1.05 points higher (95% CI: 0.07, 2.04) than those without CSI. Odds of ADL/IADL limitations were 4.45 times (95% CI: 2.00, 9.92) and 74% (95% CI: 1.24, 2.45) higher for those with severe CSI and moderate CSI. Older adults with severe CSI had 2.79 times (95% CI: 1.21, 6.43) higher hazard of incident ADL/IADL limitations. Conclusions: CSI is associated with PF and ADL/IADL limitations.

对比敏感性损伤与老年人身体功能和日常生活活动的限制有关。

对比敏感度（CS），即在背景下看清物体的能力，是视觉功能的重要组成部分。对比敏感性损伤（CSI）对身体功能（PF）的影响还没有很好的文献记载。方法：本研究从老龄化、人口统计学和记忆研究中获得数据。测量基线CS，每两年评估一次自我报告的PF、日常生活活动（ADLs）和日常生活工具活动（IADLs）。结果：样本包括263名个体，平均（SD）年龄：82.1（5.3）岁。严重CSI患者的PF限制得分比无CSI患者高1.05分（95% CI: 0.07, 2.04）。重度CSI和中度CSI患者发生ADL/IADL限制的几率分别为4.45倍（95% CI: 2.00, 9.92）和74% （95% CI: 1.24, 2.45）。严重CSI的老年人发生ADL/IADL限制的风险高出2.79倍（95% CI: 1.21, 6.43）。结论：CSI与PF和ADL/IADL限制有关。

期刊介绍： The Journal of Aging and Health is an interdisciplinary forum for the presentation of research findings and scholarly exchange in the area of aging and health. Manuscripts are sought that deal with social and behavioral factors related to health and aging. Disciplines represented include the behavioral and social sciences, public health, epidemiology, demography, health services research, nursing, social work, medicine, and related disciplines. Although preference is given to manuscripts presenting the findings of original research, review and methodological pieces will also be considered.
