To compare the mortality-predictive ability of the full- and short-form (SF) Mini Nutritional Assessment (MNA).
A prospective cohort study.
Population-representative sample.
2872 ≥65-year old men and women.
The study analyzed 1999 and 2003 datasets of the Taiwan Longitudinal Survey on Aging (TLSA). Subjects were graded for nutritional status with the full-MNA and MNA-SF of a Taiwanese-specific version (T2, containing calf circumference instead of BMI) at baseline (1999) and tracked their survival status for 4 years. Mortality-predictive abilities of the full-MNA and MNA-SF were compared using Cox regression analysis and Net Reclassification Improvement (NRI).
The full-MNA and MNA-SF have comparable abilities in predicting follow-up 4-year mortality risk according to the hazard ratios (all p<0.001) and Akaike information criterion (AIC). It also showed a slight improvement (not significant) if the full-MNA in a predictive model was replaced by the MNA-SF (NRI=0.09%, p=0.956).
The MNA-SF has at least comparable or even slightly better ability in predicting follow-up 4-year mortality risk of elderly Taiwanese. Results suggest that MNA-SF with calf circumference may possess some basic characteristics of a comprehensive and universal geriatric screening scale.
比较完整和简化（SF）迷你营养评估（MNA）的死亡率预测能力。
前瞻性队列研究。
具有代表性的人群样本。
2872 名≥65 岁的男性和女性。
本研究分析了台湾老龄化纵向研究（TLSA）的 1999 年和 2003 年数据集。受试者在基线（1999 年）时使用完整 MNA 和台湾特定版本的 MNA-SF（T2，包含小腿周长而不是 BMI）进行营养状况评分，并跟踪他们 4 年的生存状况。使用 Cox 回归分析和净重新分类改善（NRI）比较了完整 MNA 和 MNA-SF 的死亡率预测能力。
根据危险比（所有 p<0.001）和赤池信息量准则（AIC），完整 MNA 和 MNA-SF 在预测随访 4 年死亡率风险方面具有相当的能力。如果在预测模型中用 MNA-SF 替换完整 MNA，则略有改善（不显著）（NRI=0.09%，p=0.956）。
MNA-SF 至少具有相当或甚至略好的能力来预测台湾老年患者的随访 4 年死亡率风险。结果表明，包含小腿周长的 MNA-SF 可能具有全面和通用老年筛查量表的一些基本特征。
