Drescher et al. Comparison of two malnutrition risk screening methods (MNA and NRS 2002) and their association with markers of protein malnutrition in geriatric hospitalized patients. Eur J Clin Nutr 2010;64:887-93.
Serum prealbumin and retinol-binding protein concentrations were inversely associated with the severity of malnutrition as indicated by the NRS (P=0.06 and <0.01, respectively).
The NRS seems to be superior compared with the MNA and serum proteins in identifying elderly patients at risk of malnutrition during acute intercurrent illness.
