Mini nutritional assessment-short form test: criterion and predictive validity in older adults from a long-term care unity / Versión corta del test de valoración nutricional: validez de criterio y predictiva en adultos mayores de una unidad de cuidados de larga duración

Introduction: the Mini Nutritional Assessment Short-Form test (MNA-SF) is valid for malnutrition screening and diagnosis of older adults, but few studies evaluated if it predicts hospital length of stay (LOS) and were conducted in long-term care units. Objective: this study aims to evaluate the criterion and predictive validity of MNA-SF. Methods: a prospective observational study was conducted in older adults from a long-term care unity. MNA Long Form test (MNA-LF) and MNA-SF were applied, at admission and at discharge. Percentage of agreement, kappa and intra-class correlation coefficients (ICC) were determined. Sensitivity and specificity of MNA-SF were calculated. The independent association of MNA-SF with LOS (adjustment for Charlson index, sex, age, education) was assessed by Cox regression analysis [results presented as hazard ratio (HR) and 95 % confidence intervals (CI)]. Results: this sample is composed of 109 older adults (62.4 % women), aged 66-102 years. According to MNA-SF at admission, 7.3 % of participants presented normal nutrition status, 55.1 % were at risk of malnutrition and 37.6 % were malnourished. Agreement, kappa and ICC were 83.5 %, 0.692 and 0.768 at admission, and 80.9 %, 0.649 and 0.752 at discharge. MNA-SF sensitivities were 96.7 % at admission and 92.9 % at discharge; specificities were 88.9 % and 89.5 %, at admission and at discharge. According to MNA-SF at discharge, being at risk of malnutrition (HR = 0.170, 95 % CI: 0.055-0.528) or malnourished (HR = 0.059, 95 % CI: 0.016-0.223) lowered the odds of being discharged to home or to usual residence. Conclusions: a high agreement was found between MNA-LF and MNA-SF. MNA-SF revealed high sensitivities and specificities. An independent association was found between risk of malnutrition or malnutrition by MNA-SF and LOS. The use of MNA-SF instead of MNA-LF should be considered in long-term care units given its criterion and predictive validity.(AU)

Introducción: la versión corta del test de valoración nutricional (MNA-SF) es válida para la evaluación del riesgo nutricional y de la desnutriciónde los adultos mayores, pero pocos estudios han evaluado si predice la duración de la estancia hospitalaria (LOS) y se realizaron en unidadesde cuidados de larga duración.Objetivo: evaluar la validez predictiva y de criterio del MNA-SF.Métodos: se realizó un estudio observacional prospectivo en adultos mayores de una unidad de cuidados de larga duración. Se aplicaronel formulario largo del MNA (MNA-LF) y el MNA-SF al ingreso y al alta. Se determinó el porcentaje de concordancia, kappa y coeficientes decorrelación interclase (CCI). Se calcularon la sensibilidad y la especificidad del MNA-SF. Se evaluó la asociación independiente del MNA-SFcon la LOS (ajustada por: índice de Charlson, sexo, edad y educación) mediante análisis de regresión de Cox (resultados: hazard ratio [HR] eintervalos de confianza [IC] del 95 %).Resultados: esta muestra está compuesta por 109 adultos mayores (62,4 % mujeres), con edades de 66-102 años. Según el MNA-SF al ingreso,el 7,3 % de los participantes estaban bien nutridos, el 55,1 % estaban en riesgo nutricional y el 37,6 % estaban desnutridos. La concordancia,kappa y CCI fueron del 83,5 %, del 0,692 y del 0,768 al ingreso y del 80,9 %, del 0,649 y del 0,752 al alta. Las sensibilidades del MNASFfueron de 96,7 % al ingreso y de 92,9 % al alta; las especificidades fueron de 88,9 % y de 89,5 %, al ingreso y al alta. Según el MNA-SF al alta,estar en riesgo nutricional (HR = 0,170, IC 95 %: 0,055-0,528) o desnutrido (HR = 0,059, IC 95 %: 0,016-0,223) redujo las probabilidades deser dado de alta al domicilio o la residencia habitual.Conclusiones: se encontró una gran concordancia entre el MNA-LF y el MNA-SF el MNA-SF reveló grandes sensibilidad y especificidad. Seencontró una asociación independiente entre la desnutrición o el riesgo nutricional por MNA-SF y la LOS...(AU)

Impact of Nutritional Supplementation and a Psychomotor Program on Patients With Alzheimer's Disease.

This study aims to evaluate the impact of oral nutritional supplementation (ONS) and a psychomotor rehabilitation program on nutritional and functional status of community-dwelling patients with Alzheimer's disease (AD). A 21-day prospective randomized controlled trial was conducted and third intervention group performed a psychomotor rehabilitation program. Patients were followed up for 180 days. Mean (standard deviation) score of Mini Nutritional Assessment (MNA) increased both in the nutritional supplementation group (NSG; n = 25), 0.4 (0.8), and in the nutritional supplementation psychomotor rehabilitation program group (NSPRG; n = 11), 1.5 (1.0), versus -0.1 (1.1) in the control group (CG; n = 43), P < .05. Further improvements at 90-day follow-up for MNA in NSG: 1.3 (1.2) and NSPRG: 1.6 (1.0) versus 0.3 (1.7) in CG ( P < .05) were observed. General linear model analysis showed that the NSG and NSPRG ▵MNA score improved after intervention, at 21 days and 90 days, was independent of the MNA and Mini-Mental State Examination scores at baseline ( Ps > .05). The ONS and a psychomotor rehabilitation program have a positive impact on long-term nutritional and functional status of patients with AD.
