背景：非痴呆老年人的认知功能和身体残疾之间的关系还没有很好的描述。本研究的目的是要确定性能之间的关系，心理测量措施和修改后的物理性能测试（修改PPT）在老年男性和women.Methods，一百二十五名男性和女性年龄在75岁及以上，谁参加了随机对照试验的运动或激素替代疗法，从社区招募的大型和聚集的生活场所。测量方法包括线索制作A和B测验、取消随机图形测验、韦氏联想学习和20分钟延迟回忆测验、言语流畅性测验、改良PPT以及对前一年日常生活活动、药物使用和住院情况的自我报告。简单回归分析表明，在路线制定B和取消随机图测试中的表现速度与总的修改PPT得分显著相关（r = 0.29，p <0.001和r = 0.36）。p <0.001）。心理测验的因素分析表明，两个因素，认知速度因素和记忆因素，占55%的认知测试性能的方差。分层多元回归分析表明，年龄、用药次数和认知速度因素是改良PPT总分的独立预测因素。认知处理速度是这一人群身体虚弱的重要组成部分，尽管它在标准化身体表现测试中只占一小部分方差。
Background, The relationship between cognitive function and physical disability in nondemented older adults is not well characterized. The purpose of this study was to determine the relationship between performance on psychometric measures and a modified Physical Performance Test (modified PPT) in older men and women.Methods, One hundred twenty-five men and women aged 75 years and older, who were enrolled in randomized, controlled trials of exercise or hormone replacement therapy were recruited from the community-at-large and from congregate living sites. Measures obtained included Trailmaking A and B tests, Cancellation Random Figure tests, Weschler Associate Learning and 20-minute Delayed Recall, Verbal Fluency test, a modified PPT, and self-reports about performance of activities of daily living, medication use, and hospitalization in the previous year.Results. Simple regression analysis demonstrated that speed of performance on the Trailmaking B and Cancellation Random Figure tests was significantly associated with total modified PPT score (r = .29, p < .001 and r = .36. p < .001, respectively). A factor analysis of the psychometric test battery demonstrated that two factors, a cognitive speed factor and a memory factor, accounted for 55% of the variance in cognitive lest performance. Hierarchical multiple regression analyses demonstrated that age, number of medications, and the cognitive speed factor were independent predictors of total modified PPT score.Conclusions. Cognitive processing speed is a significant component of physical frailty in this population, although it accounts for a small percentage of variance on a standardized physical performance test.
