MNA-SF (Short Form)
MNA-SF: A rapid 6-item screen. If a patient scores ≤ 11, guidelines recommend proceeding directly to intervention rather than necessitating the full 18-item MNA.
Answer 6 screening items
A. Has food intake declined over the past 3 months due to loss of appetite, digestive problems, chewing or swallowing difficulties?
B. Weight loss during the last 3 months
C. Mobility
D. Has suffered psychological stress or acute disease in the past 3 months?
E. Neuropsychological problems
F. Body Mass Index (BMI)
If BMI unavailable, Calf Circumference (CC) in cm:

When to Use
When to Use
Rapid first-line nutritional screening in older adults (≥65 years).
Routine primary care or hospital admission screening.
Settings where a full 18-item nutritional assessment is too time-consuming.
High Sensitivity
The MNA-SF contains the 6 most highly predictive items from the full MNA. It takes less than 3 minutes to complete and retains 98% sensitivity for detecting malnutrition compared to the full 18-item version.
Section 2
Formula & Logic
Scoring
6 items: Intake decline, Weight loss, Mobility, Acute stress, Neuropsychological problems, BMI.
Total score: 0–14
12 - 14: Normal nutritional status
8 - 11: At risk of malnutrition
0 - 7: Malnourished
If BMI is unavailable, Calf Circumference (CC) can be substituted. CC <31cm scores 0, CC ≥31cm scores 3.
Section 3
Pearls/Pitfalls
Actionable Screening
Current geriatric guidelines suggest that if the MNA-SF score is ≤11, clinicians do not strictly need to complete the full MNA; they can proceed directly to nutritional intervention and dietitian referral based on the Short Form alone.

Evidence Appraisal
Primary Reference
Validation of the Mini Nutritional Assessment short-form (MNA-SF): a practical tool for identification of nutritional status.
Kaiser MJ et al. • Clin Nutr.. 2009;28(5):459-65. Validated the 6-item version and the calf-circumference substitution against the full MNA.
Section 6
Origins
Refinement of the MNA
Developed in 2009 to increase the uptake of nutritional screening. The original 18-item MNA was often bypassed in busy clinical environments. The MNA-SF condensed the tool to its most statistically powerful elements without sacrificing sensitivity.
