| Zusammenfassung: | Objective
The aim of this study was to establish the presence of malnutrition in elderly institutionalized people through Mini Nutritional Assessment (MNA) scores and to observe the changes of nutritional status through the Bioelectrical Impedance Vector Analysis (BIVA).
Design
Observational study.
Setting
Nursing home located in the territory of Florence (Italy).
Participants
463 elderly individuals from twelve nursing homes, all aged 65 yrs or over.
Measurements
We carried out the MNA and measured the bioelectrical parameters of resistance (R) and reactance (Xc), with standard, tetrapolar analysis at 50 kHz frequency; these bioelectrical parameters were interpreted according to BIVA analysis.
Results
According to the MNA score, 23.1% of the women and 20.4% of the males are malnourished (MNA |
