Introduction: a short version of the Mini Nutritional Assessment Large Form (MNA-LF) called Mini Nutritional Assessment Short Form (MNA-SF) is available for nutritional screening of the elderly. This MNA-SF allows the use of the circumference of the calf (CC) or body mass index (BMI) and shows a good correlation with the MNA-LF. However, only a few researches that have analyzed the validity of the MNA-SF can be found. Objective: to analyze the validity of the MNA-SF (including two different methods, based on the BMI (MNA-SF [BMI]) or using the calf circumference (MNA-SF [CC]). Design: study of diagnostic tests with 255 subjects over 65 years of age. The Chang method was used as gold standard. Cohen's Kappa index, sensitivity and specificity, positive and negative predictive values, the Youden index and the validity index were calculated. Results: the Kappa indexes for the Chang method were very low when comparing the results with those of the MNA-SF versions (IMC and CP) (0.335 and 0.286, respectively). The following validity results were obtained for MNA-SF (IMC) and MNA-SF (CP): sensitivity 70% and 67%, specificity 68% and 66% and Youden index 0.38 and 0.33, respectively, correctly classifying to 68.5% and 66.5% of the elderly. Conclusions: MNA SF is a useful tool (easy, non-invasive and quick to complete) but very limited for nutritional screening.
一种名为微型营养评定简表（MNA-SF）的微型营养评定长表（MNA-LF）的简短版本可用于老年人的营养筛查。该MNA-SF允许使用小腿围（CC）或体重指数（BMI），并且与MNA-LF显示出良好的相关性。然而，能找到的分析MNA-SF有效性的研究很少。目的：分析MNA-SF的有效性（包括基于BMI的两种不同方法（MNA-SF[BMI]）或使用小腿围（MNA-SF[CC]））。设计：对255名65岁以上受试者进行诊断测试研究。采用常氏方法作为金标准。计算了科恩kappa指数、敏感性和特异性、阳性和阴性预测值、约登指数和有效性指数。结果：将结果与MNA-SF版本（IMC和CP）的结果进行比较时，常氏方法的kappa指数非常低（分别为0.335和0.286）。MNA-SF（IMC）和MNA-SF（CP）的有效性结果如下：敏感性分别为70%和67%，特异性分别为68%和66%，约登指数分别为0.38和0.33，正确分类了68.5%和66.5%的老年人。结论：MNA SF是一种有用的工具（简便、无创且完成速度快），但在营养筛查方面非常有限。
