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.
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.
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.
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.
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.
身体健康是被认为成功老龄化的一个重要因素。使用有效且可重复的工具来对老年人的身体健康状况进行分类，可能有助于为这一人群制定适当的康复方案。
评估国际功能、残疾和健康分类（ICF）核心分类对老年人身体健康状况的分类的同时效度和可重复性。
共评估了 101 名老年人的握力、身体表现（简短身体表现测试）和身体活动水平（国际身体活动问卷）。使用 ICF 核心分类（14 个身体功能类别、4 个身体结构类别、9 个活动和参与类别以及 3 个环境因素）和损伤指数对身体健康状况进行分类，计算每个组件的损伤指数。
较高的身体活动水平与身体功能和活动与参与组件中的较低损伤指数相关，但与环境因素无关。更好的身体表现和握力也与所有组件中的较低损伤指数相关。组内相关系数分析表明，身体功能、身体结构、活动与参与的能力部分以及两个环境因素（药物使用和辅助器具）的可重复性较好，而活动与参与的表现部分的可重复性中等，与获得卫生服务有关的环境因素的可重复性较差。
老年人身体健康的 ICF 核心分类是一种有效且可重复的工具，可用于临床实践和研究。
