To contribute to the validation of the revised BMI-MNA-SF and CC- MNA-SF with regard to association and agreement with the full-MNA, considered as gold standard, in nursing homes in Spain.
Prospective analysis.
Nursing homes.
Eight hundred ninety five subjects aged 65 or older meeting inclusion criteria.
Correlation, diagnostic accuracy and agreement between the revised MNA short forms and the MNA full form.
The MNA-SFs correlated strongly with the full MNA version (Pearson's correlation coefficient r=0.904; p<0.001). High values of sensitivity, specificity and predictive values were obtained for the BMI- MNA-SF and CC-MNA-SF against the full-MNA when the dichotomized categorizations "malnourished-at risk of malnutrition" vs. "well nourished" and "malnourished" vs "at risk of malnutrition-well nourished" were considered (Youden's index at least 0.695 in all cases). Areas under the ROC curves also reached high values (BMI-SF: 0.950 and CC-SF: 0.923 for the first categorization; BMI-SF: 0.979 and CC-SF: 0.978 for the second one) showing both tests excellent accuracy with the full-MNA. The agreement between the MNA-SFs and the full-MNA was quantified as the percentage of correct classifications. The BMI-MNA-SF classified 83.80% correctly and the CC-MNA-SF classified 78.55% correctly. Significant proportions of subjects were underestimated by both MNA-SFs. Just about 6% of overestimations were found in both cases.
The revised BMI-MNA-SF and CC-MNA-SF are rapid, easy and reliable tools capable to identify malnourished individuals and those who are at risk of malnutrition with minimal misclassifications with potential harm in nursing home residents. Due to the special characteristics of elderly staying in these institutions, the CC-MNA-SF is a good option to replace the BMI-MNA-SF when BMI is not available.
验证修订后的 BMI-MNA-SF 和 CC-MNA-SF 与全 MNA 的关联性和一致性，后者被认为是金标准，应用于西班牙的养老院。
前瞻性分析。
养老院。
符合纳入标准的 895 名 65 岁或以上的受试者。
修订后的 MNA 短表与全 MNA 之间的相关性、诊断准确性和一致性。
MNA-SFs 与全 MNA 版本高度相关（Pearson 相关系数 r=0.904；p<0.001）。当将二分分类“营养不良-有营养不良风险”与“营养良好”和“营养不良”与“有营养不良风险-营养良好”进行比较时，BMI-MNA-SF 和 CC-MNA-SF 对全 MNA 具有较高的敏感性、特异性和预测值（在所有情况下，Youden 指数至少为 0.695）。ROC 曲线下的面积也达到了较高的值（第一种分类：BMI-SF：0.950 和 CC-SF：0.923；第二种分类：BMI-SF：0.979 和 CC-SF：0.978），表明这两种测试对全 MNA 都具有优异的准确性。MNA-SFs 与全 MNA 的一致性被量化为正确分类的百分比。BMI-MNA-SF 正确分类 83.80%，CC-MNA-SF 正确分类 78.55%。这两种 MNA-SFs 都低估了相当比例的受试者。两种情况下都发现了约 6%的高估。
修订后的 BMI-MNA-SF 和 CC-MNA-SF 是快速、简便、可靠的工具，能够识别营养不良和有营养不良风险的个体，且在养老院居民中具有最小的误分类潜在危害。由于这些机构中老年人的特殊特征，当 BMI 不可用时，CC-MNA-SF 是替代 BMI-MNA-SF 的一个不错选择。
