Summary
Aim of the study: To assess the usefulness of the short (MNA-SF) and full versions of the Mini Nutritional Assessment (MNA) in examining the nutritional state of older persons.
Material and methods: 311 subjects aged more than 65 years participated in the study: 151 living in an institution (DPS) (111 women and 40 men) and 160 community-dwelling elderly (116 women and 44 men).
Results: In comparison with MNA, the MNA-SF had a sensitivity of 73.6% in the community-dwelling elderly, and 64.4% in those institutionalised. In the community-dwelling elderly, 95% of persons with a good nutritional state and 73.6% of undernourished subjects were correctly classified. In an institution environment 100% persons with good nutritional state and 64.4% undernourished subjects were correctly classified by MNA-SF. In both groups MNA-SF and MNA corresponded with the findings of other measures of geriatric assessment (ADL, IADL, MMSE, GDS).
Conclusions: The study supports the usefulness of MNA-SF as a screening tool for examination of the nutritional state in the community-dwelling elderly. Generally, the full version of MNA confirmed the results of MNA-SF in this group. The relatively low sensitivity of MNA-SF in older and frailer institutionalised elderly persons requires further study.
