Assessment of food consumption, energy and protein intake in the meals offered in four Spanish nursing homes.

BACKGROUND/OBJECTIVE: The elderly, and especially those attending nursing homes, are at great risk from certain nutritional deficiencies. The aim of this study was to examine the percentage of energy wasted, energy and protein intake and percentage consumed of meal offered by a group of healthy institutionalized elderly in four nursing homes in Spain. DESIGN AND METHODS: This was a multicentre observational study of a sample of the institutionalized population over the age of 65. Our final sample comprised a total of 62 individuals. Dietary data were collected using double weight method for each meal during 21 days. We calculated the following consumption variables: percentage of food consumed (% food consumed) for each subject in each meal. We also calculated the energy intake (kcal/day), the wasted energy (kcal/day), the protein intake (g protein/ day) and the energy density (kcal/g meal) for each of the meals eaten. To analyse the overall differences we used analysis of variance test (ANOVA). The significance level used was 0.05 (p < 0.05). RESULTS: The largest meals were lunch (781 g/day [728.4, 833.6]) and dinner (653 g/day [612.1, 693.9]). The percentage of total consumption was 81.9% [79.3, 84.6]. The average energy consumption was 1,575.4 kcal/day [1,508.3, 1,642.6]. The percentage of caloric distribution varied depending on the center. The highest percentage of wasted food was found in the main meals. Forty four percent did not consume enough energy to meet the recommended intakes. Protein intake was 63.6 g protein / day [61.2, 66.1]. 12.5% of women and 4.55% of men did not consume the recommended intakes for the elderly. Breakfast and the bedtime snack had the highest energy density with 1.10 [0.9, 1.25] and 1.04 [0.9, 1.08] kcal/g food served respectively [Energy density]. DISCUSION/CONCLUSIONS: The best strategy for increasing the energy intake of the institutionalized elderly without raising the amount of food that is rejected may be to provide higher energy density foods in the same serving sizes.

Assessing risk screening methods of malnutrition in geriatric patients: Mini Nutritional Assessment (MNA) versus Geriatric Nutritional Risk Index (GNRI).

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/objetivos: Los ancianos, y especialmente los institucionalizados en residencias geriátricas, tiene un elevado riesgo de sufrir deficiencias nutricionales importantes. El objetivo de este estudio fue evaluar el porcentaje de comida consumida en cada ingesta así como la ingesta total energética y proteica en un grupo de ancianos sanos institucionalizados en cuatro residencias geriátricas de España. Métodos: Se llevó a cabo un estudio observacional multicéntrico en una muestra de población anciana (edad > 65 años) institucionalizada. La muestra final incluyó un total de 62 individuos sanos. Los datos de consumo se evaluaron mediante el método de registro de doble pesada para cada comida durante un período de 21 días consecutivos. Se calcularon las variables: porcentaje de consumo de alimentos (% ración consumida) para cada individuo en cada comida. También se calculó el consumo de energía (kcal/día), la energía desperdiciada (kcal/día), la ingesta de proteínas y la densidad calórica de las comidas (kcal/g ingesta). Para analizar las diferencias se llevó a cabo un análisis de la varianza (ANOVA). El nivel de significación usado fue de 0,05 (p < 0,05). Resultados: Las comidas más voluminosas fueron el almuerzo (781 g/día) [728,4-833,6] y la cena (653 g/día [612,1-693,9]. El porcentaje de consumo total fue del 81,9% [79,3-84,6]. El consumo de medio de energía fue de 1.575,4 kcal/día [1.508,3-1.642,6]. El porcentaje de distribución calórica varió en función de cada centro. El mayor porcentaje de desperdicio de alimentos fue en las comidas principales (almuerzo y cena). 44% de los ancianos no cubrían las recomendaciones energéticas establecidas. La ingesta de proteínas fue del 63,6 g proteína/día [61,266,1]. Un 12,5% de las mujeres y un 4,55 de los hombres no cubrieron las ingestas recomendadas de proteínas. Discusión/conclusiones: En vista de los resultados, probablemente una buena estrategia para mejorar el consumo de energía y nutrientes y reducir los porcentajes de comida desperdiciada entre los ancianos institucionalizados podría ser planificar comidas menos voluminosas y con una densidad energética y nutricional más elevada (AU)

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)
