目的：了解身体能力和功能状态之间的关系，需要设计运动干预措施，以维持独立的生活。本研究评估的重要性，身体表现在维持独立的工具性日常生活活动（IADL）。设计：预先计划的荟萃分析的横截面数据从6个网站的脆弱和损伤：干预试验的合作研究（FICSIT）。方法：以2190名社区老年人为研究对象，以IADL为因变量，以步态速度、平衡功能、握力、起椅时间为预测变量，采用多元线性回归方法对IADL与身体机能的关系进行分析。年龄，性别，教育，福尔斯自我效能，认知status.RESULTS：步态速度，平衡功能，握力独立相关的IADL赤字，校正后的协变量。线性斜率相对较陡。对于步态，降低0.1 m s（-1）与IADL缺陷增加0.10（95% CI：0.17，0.04）相关，相当于10例受试者的IADL缺陷。握力和平衡的线性斜率相似或更陡。在测量椅子站立时间的地点，起身时间增加1秒与IADL缺陷增加0.14（0.04，0.24）相关。在荟萃分析中发现的关系是一致的网站，招募对象有很大的不同水平的物理performance.CONCLUSION：简单的物理性能的措施与IADL的独立性校正后，许多以前确定的功能状态的预测因素。来自该荟萃分析的数据支持旨在改善身体表现的测试干预措施，以确定改善的表现是否可以保持或改善IADL的独立性。
OBJECTIVES: Understanding the relationship between physical capacity and functional status is required to design exercise interventions to maintain independent living. This study assessed the importance of physical performance in maintaining independence in Instrumental Activities of Daily Living (IADL).DESIGN: A pre-planned meta-analysis of cross-sectional data from six sites of the Frailty and Injury: Cooperative Studies of Intervention Trials (FICSIT). Linear regression was used to estimate the relationship between physical performance and IADL.PARTICIPANTS: 2190 community-dwelling older subjects.MEASUREMENTS: IADL was the dependent variable; gait velocity, balance function, grip strength and chair rise time were the predictor variables. Age, gender, education, falls self-efficacy, and cognitive status were covariates.RESULTS: Gait velocity, balance function, and grip strength were independently related to IADL deficits, after correcting for covariates. The linear slopes were relatively steep. For gait, a decrease of 0.1 m s(-1) was associated with 0.10 (95% CI: 0.17, 0.04) increase in IADL deficits, which is equivalent to I ADL deficit in 10 subjects. The linear slopes for hand grip and balance were similar or steeper. In the sites where chair stand time was measured, an increase of 1 second in the time to rise was associated with a 0.14 (0.04, 0.24) increase in IADL deficits. The relationships found in the meta-analytic analysis were consistent across sites which enrolled subjects with widely varying levels of physical performance.CONCLUSION: Simple measures of physical performance were strongly associated with IADL independence after correcting for many previously identified predictors of functional status. The data from this meta-analysis support testing interventions designed to improve physical performance to determine whether improved performance can maintain or improve independence in IADLs.
