Relationships Between Nutritional Markers and the Mini-Nutritional Assessment in 155 Older Persons
ABSTRACT To investigate the relationships between nutritional status measured by a comprehensive nutritional assessment including anthropometric measurements, nutritional biological markers, evaluation of dietary intake, and the Mini-Nutritional Assessment (MNA) nutrition screening tool.
A prospective study.
One hundred fifty-five older subjects (53 men and 102 women; mean age = 78 years; range = 56-97 years). These participants were hospitalized in a geriatric evaluation unit (n = 105) or free living in the community (n = 50).
Weight, height, knee height, midarm and calf circumferences, triceps and subscapular skinfolds, albumin, transthyretin (prealbumin), transferrin, ceruloplasmin, C-reactive protein, alpha1-acid glycoprotein, cholesterol, vitamins A, D, E, B1, B2, B6, B12, folate, copper, zinc, a 3 day food record combined with a food-frequency questionnaire; the MNA nutritional screening.
The MNA scores have been found to be significantly correlated to nutritional intake (P < .05 for energy, carbohydrates, fiber, calcium, vitamin D, iron, vitamin B6, and vitamin C), anthropometric and biological nutritional parameters (P < .001 for albumin, transthyretin, transferrin, cholesterol, retinol, alpha-tocopherol, 25-OH cholecalciferol zinc). An MNA score between 17 and 23.5 can identify those persons with mild malnutrition in which nutrition intervention may be effective.
The MNA is a practical, noninvasive, and cost-effective instrument allowing for rapid nutritional evaluation and effective intervention in frail older persons.

ABSTRACT: Resumo Existem fatores que podem infl uenciar a nutrição dos idosos, ocasionando a desnutrição ou o risco de desnutrição, dentre os quais podemos citar: a incapacidade de realizar sozinhas as atividades cotidianas, alterações fi siológicas próprias do envelhecimento, isolamento social, doenças, fatores psicológicos e outros. O objetivo deste estudo foi diagnosticar o risco de desnutrição e desnutrição em idosos institucionalizados. Foram avaliados 20 idosos utilizando a Mini Avaliação Nutricional (MAN) e o Índice de Massa Corporal (IMC). Os resultados da MAN indicaram que 10% dos idosos encontram-se desnu-tridos, 30% dos idosos em risco de desnutrição e 60% eutrófi cos. Pode concluir que, apesar de outros estudos mostrarem a alta prevalência de idosos desnutridos, este trabalho mostrou uma porcentagem baixa (10%) de desnutrição nesta instituição. Palavras-chave: idosos, desnutrição, estado nutricional. Abstract Many factors can infl uence the nutrition of the elderly, leading to malnutrition or risk of malnutrition, among which the more frequent are the inability to perform daily activities alone, physiological changes of aging, social isolation, diseases, psychological factors, and other. Th is study aimed to diagnose the risk of malnutrition and malnutrition in institutionalized elderly. Were evaluated 20 elderly using the Mini Nutritional Assessment (MAN) and Body Mass Index (BMI). Th e results of the MAN indicated that 10% of the elderly were at undernutrition, 30% were at risk of malnutrition and 60% eutrophic. May conclude that, although other studies show a high prevalence of undernutrition in elderly, this study showed a low percentage (10%) of malnutrition in this institution.

ABSTRACT: Malnutrition is frequent among older people and is associated with morbi-mortality. The aim of the study is to assess the effectiveness of a multifactorial and multidisciplinary intervention in the nutritional status among the elderly. Randomized, single-blind, parallel-group, clinical trial conducted from January 2009 to December 2010 in seven primary health care centers in Baix Llobregat (Barcelona). Of 696 referred people, born in 1924, 328 subjects were randomized to an intervention group or a control group. The intervention model used an algorithm and was multifaceted for both the patients and their primary care providers. The main outcome was improvement in nutritional status assessed by Mini Nutritional Assessment (MNA). Data analyses were done by intention-to-treat. Two-year assessment was completed for 127 patients (77.4%) in the intervention group and 98 patients (59.7%) in the control group. In the adjusted linear mixed models for MNA, intervention showed no significant effect during all follow-up period with -0.21 (CI: - 0.96; 0.26). In subjects with nutritional risk (MNA ≤ 23.5 / 30) existed a tendency towards improvement in MNA score 1.13 (95% CI -0.48; 2.74) after 2 years. A universal multifactorial assessment and target intervention over a two year period in subjects at nutritional risk showed a tendency to improve nutrition but not in the rest of community-dwelling studied subjects. Cognitive impairment was an independent factor strongly associated with a decline in nutritional status. The clinical trial is registered as part of a US National Institutes of Health Clinical Trial: NCT01141166 .BMC Geriatrics 04/2015; 15(1):45. DOI:10.1186/s12877-015-0033-0 · 2.00 Impact Factor

ABSTRACT: Introduction: The Mini Nutritional Assessment (MNA) is a scale developed to evaluate the risk of malnutrition in senior citizens and to identify those who might benefit from early intervention. The objective of this study was to verify the nu-tritional profile of elderly individuals through the application of the MNA in three different locations: at the Geriatric outpatient clinic and two long-term institutions. Methods: Through transversal observation study the MNA was applied to 90 elderly people of both genders over 60 years of age. The MNA version modified by Rubenstein et al.  and translated into Portuguese was used to evaluate the patients for this study. The descriptive analysis of variables is shown as the average ± one standard deviation (SD). Results: At the AG, the risk of malnutrition was found to be 72.73% ± 3.77%, while 27.27% ± 3.77% of the patients were eutrophic; no malnourished elderly patients were found. At the ASVP, 15.38% ± 11.28% of elderly patients were found to be malnourished, 35.90% ± 15.10% were found to be at risk of malnutrition and 48.72% ± 15.72% were eutrophic. At the PMI, 42.50% ± 15.30% of the elderly patients were found to be malnourished, 25% ± 13.40% were at risk of malnutrition and 32.50% ± 14.50% were eutrophic. Conclu-sions: Due to the high prevalence of elderly patients that were malnourished or at risk of malnutrition, a more detailed evaluation of their nutritional states is required, as well as a regular follow up of those patients and a dietary interven-tion to reverse the situation.
