Assessing the prevalence of malnutrition with the Mini Nutritional Assessment (MNA) in a nationally representative sample of elderly Taiwanese

Objective: The study was to determine whether the Mini Nutritional Assessment (MNA) could be used as a tool to effectively identify malnourished elderly in a non-Caucasian population.Design: The study was a part of a population-based multistage random sample survey.Setting: In-home face-to-face interviews.Participants: Randomly selected 1583 men and 1307 women, 65 years or older, in Taiwan.Measurements: Assessing nutritional risk status of participants with the Mini Nutritional Assessment.Results: The prevalence of malnutrition is 1.7% in elderly men and 2.4% in elderly women, 65 years or older. The proportion at risk of malnutrition is 13.1%.Conclusion: To the best of our knowledge, this is the first study to apply the MNA to estimate the prevalence of malnutrition in the elderly in a nationally representative sample. Results suggest that the MNA can identify malnourished elderly in a non-Caucasian population. However, it appears that the functionality of the instrument can be improved by adapting population-specific anthropometric cutoff standards.
