The aim was to determine validity, reliability, and cutoff of full-mini nutritional assessment (MNA) and MNA-short form (SF) also which one was better for the screening of malnutrition in the Iranian hospitalized elderly. Methods: In this cross-sectional validation study, 96 hospitalized elderly ≥60 years selected from two hospitals in Tehran. Anthropometric measures (body mass index BMI, mid-arm circumference MAC, calf circumference CC, abdomen, and waist skinfold thickness) and laboratory tests (albumin and hemoglobin levels, and red blood cell count were performed. Nutrition tools (full-MNA and MNA-SF), cognition tool (mini-mental state examination, depression scale (Geriatric Depression Scale15 and activities of daily living (ADL) index (Modified Barthel-ADL) were administered. Results: The full-MNA scores were significantly correlated to measures of MAC, BMI, waist, and CC. The MNS-SF scores were significantly related to measures of MAC, waist, and CC. Serum albumin showed a poor correlation with both tools. At cutoff 24 in full-MNA had a sensitivity 75 and specificity 77.8 and the MNA-SF considered 62.5 sensitivity and 65.3 specificity at cutoff 10.50 to detect well-nourished from malnourished subjects. The internal consistencies of both tools were 90. In exploratory factor analysis, six components found for full-MNA and two components for MNA-SF. Known group validity of full-MNA was reflected significant differences between geriatric patients with expected higher full-MNA scores and patients with expected lower scores (BMI ≥24 vs. BMI 24 or bed ulcer or assisted food intake). Conclusions: It seems the Persian version of full-MNA is more appropriate in comparison to MNA-SF for screening malnutrition in the Iranian hospitalized elderly patients.
