Elderly subjects are considered a vulnerable group and they have more risk of nutritional problems. The risk of malnutrition increases in hospitalized geriatric patients.
To compare the correlation between MNA and GNRI with anthropometric, biochemical and Barthel Index in hospitalized geriatric patients and to test the concordance between MNA and GNRI and between Mini Nutritional Assessment Short Form (MNA-SF) and MNA.
It was a cross-sectional study on a sample of 40 hospitalized geriatric patients. For determination nutritional status we used MNA and GNRI; we evaluated the correlation between this both test with biochemical and anthropometric parameters and functional questionnaires. We used Pearson's simple correlation model, oneway ANOVA and multiple logistic regression to evaluate the relationship between MNA and GNRI.
According to MNA, 17 patients (42.5%) were malnourished and according to GNRI, 13 patients (32.5%) had high risk of nutritional complications. The concordance of MNA and GNRI was 39% and between MNA-SF and MNA was 81%. The most significant differences were detected in weight, BMI, arm and calf circumference and weight loss parameters. Barthel index was significantly different in both tests. The MNA and GRNI had significant correlations with albumin, total protein, transferring, arm and calf circumference, weight loss and BMI parameters.
In conclusion, it would be reasonable to use GRNI in cases where MNA is not applicable, or even use GRNI as a complement to MNA in hospitalized elderly patients. There is no reason why they should be deemed incompatible, and patients could benefit from more effective nutritional intervention.
老年人群被视为弱势群体，他们面临更多营养问题风险。老年住院患者营养不良风险增加。
比较住院老年患者中营养不良通用筛查工具（MNA）和老年营养风险指数（GNRI）与人体测量、生化指标及巴氏指数之间的相关性，并检验MNA与GNRI之间以及微型营养评定简表（MNA-SF）与MNA之间的一致性。
对40例老年住院患者样本进行横断面研究。我们使用MNA和GNRI来确定营养状况；评估这两种检测方法与生化、人体测量参数及功能问卷之间的相关性。我们使用Pearson简单相关模型、单因素方差分析和多元逻辑回归来评估MNA与GNRI之间的关系。
根据MNA，17例患者（42.5%）营养不良；根据GNRI，13例患者（32.5%）有营养并发症高风险。MNA与GNRI的一致性为39%，MNA-SF与MNA之间的一致性为81%。在体重、体重指数（BMI）、上臂和小腿围以及体重减轻参数方面检测到最显著差异。两种检测中，巴氏指数均有显著差异。MNA和GRNI与白蛋白、总蛋白、转铁蛋白、上臂和小腿围、体重减轻及BMI参数均有显著相关性。
总之，在MNA不适用的情况下使用GRNI是合理的，甚至在老年住院患者中可将GRNI作为MNA的补充。没有理由认为它们不兼容，患者可从更有效的营养干预中获益。
