Background

Physical health is an important factor for what is considered successful aging. Using valid and reproducible tools to classify PH of older adults may help to develop appropriate rehabilitation protocols for this population.

Objective

To evaluate the convergent validity and reproducibility of the International Classification of Functioning, Disability and Health (ICF) core set to classify the physical health of older adults.

Methods

A total of 101 older adults were evaluated for handgrip strength, physical performance (Short Physical Performance Battery), and physical activity level (International Physical Activity Questionnaire). Physical health was classified with the ICF core set (14 categories of body functions, 4 of body structures, 9 of activity and participation, and 3 environmental factors) and an impairment index was calculated for each component.

Results

Higher levels of physical activity were associated to lower impairment index in the body function and activity and participation components, but was not associated to environmental factors. Better physical performance and handgrip strength were also related to lower impairment index in all components. The Intraclass Correlation Coefficient analysis indicated good reproducibility for body function, body structure, the capacity component of the activity and participation, and for two environmental factors (use of medications and assistive devices), but moderate reproducibility for the performance component of activity and participation, and poor reproducibility for the environmental factor related to access to health services.

Conclusion

The ICF core set for the physical health of older adults is a valid and reproducible tool and can be used in clinical practice and research.

国际功能、残疾和健康分类 (ICF) 社区老年人身体健康核心集的收敛有效性和可重复性

背景

身体健康是成功老龄化的一个重要因素。使用有效且可重复的工具对老年人的 PH 进行分类可能有助于为该人群制定适当的康复方案。

客观的

旨在评估国际功能、残疾和健康分类 (ICF) 核心集对老年人身体健康进行分类的收敛有效性和再现性。

方法

共有 101 名老年人接受了握力、身体表现（短期身体表现电池）和身体活动水平（国际身体活动问卷）的评估。身体健康按照ICF核心集（14类身体功能、4类身体结构、9类活动和参与、3类环境因素）进行分类，并计算每个组成部分的损伤指数。

结果

较高水平的体力活动与较低的身体功能、活动和参与成分损伤指数相关，但与环境因素无关。更好的身体表现和握力也与所有组件的损伤指数较低有关。组内相关系数分析表明，身体功能、身体结构、活动和参与的能力部分以及两个环境因素（药物和辅助设备的使用）具有良好的再现性，但活动和参与的表现部分的再现性中等，与获得卫生服务相关的环境因素的可重复性较差。

结论

针对老年人身体健康的 ICF 核心集是一种有效且可重复的工具，可用于临床实践和研究。
