营养是老年人健康的一个关键因素，对功能能力很重要。本研究探讨了微型营养评估（MNA）的功能状态预测能力。我们分析了台湾健康促进局进行的“台湾老年人健康与生活状况调查”的数据集。完成1999年和2003年调查的研究受试者（≥ 65岁）在基线时使用MNA的长表和短表进行评分，并在4年后（终点）使用日常生活活动（ADL）和日常生活工具活动（IADL）量表进行评分。MNA预测ADL或IADL依赖的能力用逻辑回归模型进行评估。结果显示，在基线时被评定为营养不良或有营养不良风险的老年人，4年后的ADL或IADL评分通常显著较高。较低的基线MNA评分也预示着更大的ADL或IADL依赖风险。这些关联甚至存在于基线时无ADL或IADL依赖的老年人中。结果清楚地表明，MNA是能够预测ADL和IADL依赖（除了评级当前的营养状况）的老年人。在临床实践或社区方案中，MNA，特别是简表，应成为识别有功能衰退和/或营养不良风险的老年人的宝贵工具。
Nutrition is a key element in geriatric health and is important for functional ability. The present study examined the functional status-predictive ability of the Mini-Nutritional Assessment (MNA). We analysed the dataset of the 'Survey of Health and Living Status of the Elderly in Taiwan', a population-based study conducted by the Bureau of Health Promotion of Taiwan. Study subjects (>= 65 years old) who completed both the 1999 and 2003 surveys were rated with the long form and short form of the MNA at baseline and with the Activities of Daily Living (ADL) and the Instrument Activities of Daily Living (IADL) scales 4 years later (end-point). The ability of the MNA to predict ADL or IADL dependency was evaluated with logistic regression models. The results showed that the elderly who were rated malnourished or at risk of malnutrition at baseline generally had significantly higher ADL or IADL scores 4 years later. Lower baseline MNA scores also predicted a greater risk of ADL or IADL dependency. These associations exist even among the elderly who were free of ADL or IADL dependency at baseline. The results clearly indicate that the MNA is able to predict ADL and IADL dependency (in addition to rating current nutritional status) of the elderly. The MNA, especially the short form, should be a valuable tool for identifying elderly at risk of functional decline and/or malnutrition in clinical practice or community programmes.
