Nutritional assessment of an elderly population by application of 24-hour recall and the Mini Nutritional Assessment
| Resumo: | Introduction: Aging is characterized by physiological, social and psychological changes that compromise food intake and nutritional status. To ensure good nutritional status it’s crucial to assess the nutritional status through a validated tool and evaluate the food intake, which is the purpose of this study. Methods: An analytical, observational, transversal, correlational and quantitative study was conducted. The elderly’s assessment and characterization was done by the application of Mini Nutritional Assessment (MNA), arm circumference (AC), laboratory parameters and 24 hours recall. Results: In the study, 42 elderly people were assessed, from which 26 women. By applying the MNA_Long Form® (MNA_LF®) 0 were undernourished, 26 (62%) at risk of desnutrition and 16 (38%) eutrophic. By applying the body mass index (BMI) 2 (5%) undernourished, 6 (15%) at risk of desnutrition, 7 (17%) eutrophic e 26 (63%) overweight. By the AC 19 (45%) exhibit depletion of lean body mass, 20 (48%) good nutritional state and 3 (7%) excess of body fat. The 24 hours recall indicated low intake of macronutrients and of some micronutrients (vitamins A, D, and E, folate, potassium, calcium, and magnesium) and high intake of sodium and phosphorus. The AC correlated with IMC (r = 0,61; p = 0) and MNA_LF (r = 0,45; p = 0,003). The IMC correlated with the presence of dyslipidemia (r = 0,41; p = 0,01), diabetes mellitus (r = 0,45; p = 0,003) and arterial hypertension (r = 0,375; p = 0,02). Key conclusions: The population being studied showed a high prevalence of malnutrition, a similar percentage of risk of desnutrition and overnutrition, and a deficit of food intake, as seen in other Portuguese studies about the elderly in the community. |
