Abstract
Background
Brazilian population has passed for a process of demographic transition throughout latest years, characterized for the increase of the elderly population. Malnutrition is a serious problem to frail elderly.
Objective
The objective of this study was o evaluate the risk of malnutrition among institutionalized elderly resident in municipal shelters in the city of Rio de Janeiro, Brazil, using the tool Mini Nutritional Assessment (MNA).
Design
344 institutionalized elderly aged over 60 years old were tested in a cross-sectional study using MNA. This tool classifies the nutricional status of the elderly in three groups: malnutrition (score < 17), risk of malnutrition (score 17–23,5) and well-nourished (score > = 24). Anthropometric measurements such as calf circumference (CC), mid-arm circumference (MAC) and Body mass index (BMI) were also evaluated. The variables were evaluated using the chi-square or A NOVA test. To correlate it was used Pearson’s Correlation Coefficient (r).
Results
Mean age were 75.4 (+− 9.4) years old. Most of the elderly were female gender (59.6%). According to MNA 8.3% were with malnutrition, 55.6% at risk of malnutrition and 36.1% well-nourished BMI classified 10.0% of the elderly as underweight. CC classified 10.0 % of them as inadequate in muscular mass. MNA was well correlated to BMI (r=0.41 2 p=0.000), age (r=−0.124 p=0.031), CC (r=0.399 p = 0.000) and MAC (r=0.391 p=0.000).
Conclusion
Risk of malnutrition was high among the institutionalized elderly from public shelters in Rio de Janeiro — Brazil. MNA is a useful diagnostic tool for the identification on the frail elderly at risk of malnutrition.
