BACKGROUND
Self-rated health (SRH) holistically captures older adults' health status from the perspective of the individual.
AIMS
To explore the accuracy of five objective health indicators related to diseases, physical function, cognition and disability in discriminating SRH among the youngest and oldest old.
METHODS
We used baseline data from 2196 participants of the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K), Sweden (years 2001-2004). Area under the receiver operating characteristic curves (AUROC) were obtained from logistic regressions adjusted by sex, age and education.
RESULTS
Among the youngest old, having ≥ 4 chronic diseases showed the highest discriminatory capacity of poor versus good SRH (AUROC: 0.714). Among the oldest old, a walking speed < 1.0 m/s showed the highest discriminatory capacity of poor versus good SRH (AUROC: 0.683), followed by ≥ 1 limitations in IADL (AUROC: 0.664).
CONCLUSION
What matters most for SRH in older people depends on age, with walking speed playing a major role among the oldest old.
背景
自评健康（SRH）从个体角度整体捕捉老年人的健康状况。
目的
探讨与疾病、身体功能、认知和残疾相关的五种客观健康指标在区分最年轻和最年长老年人的 SRH 方面的准确性。
方法
我们使用了来自瑞典 Kungsholmen 老龄化和护理全国研究（SNAC-K）的 2196 名参与者的基线数据（2001-2004 年）。通过性别、年龄和教育调整的逻辑回归获得了受试者工作特征曲线下的面积（AUROC）。
结果
在最年轻的老年人中，患有≥4 种慢性病对不良与良好 SRH 的区分能力最高（AUROC：0.714）。在最年长的老年人中，行走速度<1.0 m/s 对不良与良好 SRH 的区分能力最高（AUROC：0.683），其次是 IADL 受限≥1 项（AUROC：0.664）。
结论
对老年人的 SRH 最重要的因素取决于年龄，而在最年长的老年人中，行走速度起着重要作用。
