RESUMO
INTRODUCTION: Elderly subjects are considered a vulnerable group and they have more risk of nutritional problems. The risk of malnutrition increases in hospitalized geriatric patients. OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Antecedentes: La población anciana esta considerada como un colectivo vulnerable a sufrir problemas nutricionales. Entre estos, los ancianos hospitalizados tienen aun un mayor riesgo a sufrir malnutrición. Objetivos: Los objetivos de este estudio fueron comparar el grado de correlación entre dos índices de cribaje nutricional, el Mini Nutritional Assessment (MNA) y el Geriatric Nutritional Risk Index (GNRI) con los parámetros antropométricos, bioquímicos, el índice de Barthel y ciertas patologías relacionadas con el estado nutricional (infecciones y úlceras por presión). Metodología: Se llevó a cabo un estudio transversal en una muestra de 40 pacientes hospitalizados en una unidad geriátrica de agudos. Para la determinación del estado nutricional se usaron los índices del MNA y el GNRI. Se evaluó la correlación entre los parámetros bioquímicos, antropométricos, parámetros funcionales y problemas nutricionales relacionados con la malnutrición (úlceras por presión y infecciones). Para el modelo de correlación, se utilizó el grado de correlación de Pearson; para estudiar la relación entre los índices nutricionales (MNA y GNRI) y los diferentes parámetros se utilizó un análisis de la variancia y un modelo de regresión logística. Resultados: De acuerdo con el MNA, 17 pacientes (42,5%) estaban desnutridos y de acuerdo con GNRI, 13 pacientes (32,5%) tenían alto riesgo de complicaciones nutricionales. La concordancia de la MNA y la GNRI fue del 39% y entre MNA-SF y MNA fue de 81%. Las diferencias más significativas se detectaron en el peso, el IMC, el brazo y circunferencia de la pantorrilla y los parámetros de pérdida de peso. El MNA y GRNI mostró correlaciones significativas con la albúmina, proteínas totales, la transferencia, la circunferencia del brazo y de la pantorrilla, con el % de pérdida de peso y el índice de masa corporal (IMC). Los pacientes malnutridos según el MNA y los pacientes con riesgo elevado según el GNRI tenían mayor riesgo de sufrir úlceras por presión. Conclusiones: en conclusión, sería razonable utilizar el GNRI en los casos en que el MNA no fuera aplicable, o incluso utilizar GNRI como complemento al MNA en pacientes ancianos hospitalizados. No hay ninguna razón por la cual se deban considerar incompatibles, y los pacientes podrían beneficiarse de una intervención nutricional más efectiva (AU)
