背景和目标：为了可能验证使用迷你营养评估（MNA）的功能状态institutionalised elderly.Methods：一百二十三个长期护理居民老人（85.3 +/- 8.4岁）被招募。分别用MNA和Barthel指数（131）评估营养和功能状态。主要入选标准为MNA < 23.5。结果：MNA与BI呈显著相关（r = 0.55; p < 0.0001）。营养不良（MNA < 17）的特点是较低的BMI，肌肉质量，不良的营养习惯和较高的体重减轻和残疾。同样，较差的功能状态与低BMI、肌肉减少症和口服摄入量减少有关。MINA和BI之间的相互关系进行了研究，逐步纳入变量的多元回归模型（一个/分析）。MNA和BI之间的初始关联（p < 0.0001）被体重减轻（p < 0.02）、肌肉质量（p < 0.03）和口服摄入（p < 0.05）掩盖。然而，当BI作为因变量时，与MNA的关联依赖于肌肉减少症（P < 0.05）和减少的食物消耗（P < 0.001）。结论：MNA可靠地识别需要更高标准护理的有风险的机构化老年人，特别是与饮食有关的老年人。常规记录口服摄入量和喂养辅助可能有助于防止体重减轻、肌肉减少和功能状态恶化。(C)2008年爱思唯尔有限公司和欧洲临床营养与代谢学会。All rights reserved.
Background & aims: To possibly validate the use of Mini Nutritional Assessment (MNA) with respect to functional status in institutionalised elderly.Methods: One hundred twenty-three tong-term care resident elderly (85.3 +/- 8.4 years) were recruited. Nutritional and functional states were assessed by MNA and Barthel Index (131), respectively. Main inclusion criterion was a MNA < 23.5. Anthropometric, biochemical data and oral intake (percentage of food consumed to that delivered) were evaluated.Results: MNA significantly correlated with BI (r = 0.55; p < 0.0001). Malnutrition (MNA < 17) was characterized by lower BMI, muscle mass, poor nutritional habits and higher weight loss and disability. Similarly, poorer functional status was associated with low BMI, sarcopenia and reduced oral intake. The interrelationship between MINA and BI were investigated by multiple regression models with progressive inclusion of variables (one/analysis). The initial association between MNA and BI (p < 0.0001) was masked by weight loss (p < 0.02), muscle mass (p < 0.03) and oral intake (p < 0.05). However, when BI was included as dependent variable the association with MNA depended on sarcopenia (p < 0.05) and reduced food consumption (P < 0.001).Conclusions: MNA reliably identifies at-risk institutionalised elderly needing higher standards of care, particularly related to eating. Routine documentation of oral intakes and feeding assistance might be useful to prevent weight Loss, sarcopenia and functional status deterioration.
