Intrinsic Capacity in integrated geriatric care emphasizes the importance of a thorough functional assessment. Monitoring the intrinsic capacity of older individuals provides standardized and reliable information to prevent early disability. This study assessed the relationship between intrinsic capacity and functional ability in older adults.
This cross-sectional study involved 210 older individuals aged 60 and above referred to Rasoul Akram Hospital. Data collection included ADL and IADL scales, the Snellen chart, the Hearing Handicap Inventory, the hand dynamometer, the TUG test, the AMT test, and the GDS. Data analysis was conducted using SPSS software v.26 via independent t-tests, ANOVA, Pearson correlation coefficient, and multiple regression analysis.
The participants were 70.13 ± 7.04 years. 57.6% were older females and 42.4% were older males. Age showed a significant and inverse correlation with both ADL (P < 0.001, r = -0.23) and IADL (P < 0.001, r = -0.39). The adjusted coefficient of determination (R²) for the five domains of intrinsic capacity (sensory, cognitive, locomotion, psychological, vitality) as well as age and BMI was 0.16 for ADL and 0.32 for IADL.
Age and TUG could only weakly explain ADL changes, while vision, hand grip strength, cognition, and age had moderate predictive ability of IADL. Therefore, by assessing these predictors, we can predict disability before it occurs and make necessary interventions.
综合老年护理中的内在能力强调了全面功能评估的重要性。监测老年人的内在能力可提供标准化且可靠的信息，以预防早期残疾。本研究评估了老年人内在能力与功能能力之间的关系。
这项横断面研究纳入了210名60岁及以上转诊至拉苏勒·阿克拉姆医院的老年人。数据收集包括日常生活活动能力（ADL）和工具性日常生活活动能力（IADL）量表、斯内伦视力表、听力障碍量表、握力计、定时起立步行测试（TUG测试）、简易精神状态检查表（AMT测试）和老年抑郁量表（GDS）。使用SPSS 26.0软件通过独立样本t检验、方差分析、皮尔逊相关系数和多元回归分析进行数据分析。
参与者的年龄为70.13±7.04岁。57.6%为老年女性，42.4%为老年男性。年龄与ADL（P<0.001，r = -0.23）和IADL（P<0.0让你，r = -0.39）均呈显著负相关。内在能力五个领域（感觉、认知、运动、心理、活力）以及年龄和体重指数对ADL的调整决定系数（R²）为0.16，对IADL为0.32。
年龄和TUG测试只能微弱地解释ADL的变化，而视力、握力、认知和年龄对IADL具有中等预测能力。因此，通过评估这些预测因素，我们可以在残疾发生前进行预测并采取必要的干预措施。
