The present study aimed to assess the concurrent validity of the International Classification of Functioning, Disability and Health (ICF) core set to classify physical health of older adults in relation to self-rated health.
This is a methodological study conducted in Santa Cruz, Rio Grande do Norte (RN) state, in Northeastern Brazil, with 101 community-dwelling older adults. The participants rated their health status, which was classified into 3 groups: very good, fair, and poor/very poor. An interview was then conducted using self-reported and objective measurements to classify physical health according to the ICF core set. It consists of 30 categories, 14 of which belong to the body function (b) component, 4 to body structures (s), 9 to activities and participation (d), and 3 related to environmental factors (e). To analyze the compromised and problematic categories in the ICF, an impairment index was created for each component. The relationship between self-rated health and the impairment indexes was assessed using the multinomial logistic regression test adjusted for age, sex, schooling, and perception of income sufficiency.
A greater likelihood of poor or very poor self-rated health was found in older individuals with the highest impairment index in (b) (odds ratio [OR] = 1.18; P < .001); (s) (OR = 1.11; P ≤ .001); (d) capacity (OR = 1.09; P = .02); and (d) performance (OR = 1.08; p = 0.01).
The results suggest that the ICF core set is a valid instrument to assess the physical health of older adults, since it is associated with self-rated health and shows potential for use in clinical practice and scientific research, with universal language regarding functionality and physical health in older adults.
本研究旨在评估《国际功能、残疾和健康分类》（ICF）核心分类对老年人身体健康与自我报告健康的关联的同时效度。
这是一项在巴西东北部北里奥格兰德州圣克鲁斯进行的方法学研究，共纳入 101 名社区居住的老年人。参与者根据自我报告的健康状况对其健康状况进行了分类，分为三个组别：非常好、一般和差/非常差。随后，通过自我报告和客观测量对身体状况进行访谈，根据 ICF 核心分类进行分类。它由 30 个类别组成，其中 14 个属于身体功能（b）组成部分，4 个属于身体结构（s），9 个属于活动和参与（d），3 个与环境因素（e）有关。为了分析 ICF 中的受损和出现问题的类别，为每个组成部分创建了一个损伤指数。使用调整后的年龄、性别、教育程度和收入充足感的多变量逻辑回归检验来评估自我报告健康状况与损伤指数之间的关系。
发现自我报告健康状况较差或非常差的老年人，其（b）（比值比[OR] = 1.18；P <.001）、（s）（OR = 1.11；P ≤.001）、（d）能力（OR = 1.09；P =.02）和（d）表现（OR = 1.08；P = 0.01）损伤指数最高。
结果表明，ICF 核心分类是评估老年人身体健康的有效工具，因为它与自我报告的健康状况相关，并且具有在临床实践和科学研究中应用的潜力，具有老年人功能和身体健康的通用语言。
