This study aimed to compare physical function and cognitive status according to the level of dependence in basic activities of daily living (ADL) and to determine which of these variables better predict functional independence.
This cross-sectional study included 231 individuals over 90 years of age. Physical function was assessed using the Timed Up and Go (TUG) test and handgrip strength (HGS), and cognitive function was assessed using the Mini-Mental State Examination (MMSE). A binary logistic regression adjusted for age was conducted to identify which variables related to physical performance or cognitive status could predict independence in basic ADL.
The results showed that the model including TUG (OR = 4.3; 95% CI = 2.18-8.34) along with HGS (OR = 2.0; 95% CI = 1.14-3.45) provided the best fit. This indicates that better performance on the TUG test increases the odds of independence by 4.3 times, and each increment in HGS doubles that chance.
We conclude that older individuals with better physical function and greater muscle strength are more likely to be independent in ADL.
本研究旨在根据日常生活基本活动（ADL）的依赖程度比较身体功能和认知状态，并确定这些变量中哪一个能更好地预测功能独立性。
这项横断面研究纳入了231名90岁以上的个体。使用计时起立行走测试（TUG）和握力（HGS）评估身体功能，使用简易精神状态检查表（MMSE）评估认知功能。进行了一项经年龄调整的二元逻辑回归分析，以确定哪些与身体表现或认知状态相关的变量可以预测基本ADL的独立性。
结果显示，包含TUG（比值比[OR]=4.3；95%置信区间[CI]=2.18-8.34）和HGS（OR=2.0；95%CI=1.14-3.45）的模型拟合度最佳。这表明TUG测试表现越好，独立的几率增加4.3倍，握力每增加一次，该几率翻倍。
我们得出结论，身体功能较好且肌肉力量较强的老年人在ADL方面更有可能保持独立。
