How to Use This Calculator
  1. Enter BMI, recent weight loss percentage, and reduced food intake scores.
  2. Enter mobility, psychological stress, and dementia/depression indicators.
  3. Review the Mini-Nutritional Assessment (MNA) Total Score.
  4. Check the Nutritional Status Classification: well-nourished, at risk, or malnourished.
  5. Use the result to initiate dietitian referral and nutritional intervention planning.

What each input means

Food Intake Decline
Food intake change over past 3 months.
Weight Loss
Recent weight loss.
Mobility
Mobility level.
Acute Disease/Stress
Acute illness or psychological stress in past 3 months.
Neuropsych Problems
Neuropsychological problems.
Weight
Current body weight in kilograms.
Height
Height in centimeters.
Calf circumference
Maximum calf circumference in cm. Used as alternative to BMI if needed.
Age
Patient age for caloric need calculation.
Sex
Biological sex. Affects caloric need calculation.

What each result means

MNA-SF score (0-14)
12-14 = normal, 8-11 = at risk, 0-7 = malnourished.
Nutritional status (1-3)
1 = Normal, 2 = At risk of malnutrition, 3 = Malnourished.
BMI
Body Mass Index (kg/m2).
MNA-SF (using calf circ.)
Alternative score using calf circumference instead of BMI for item F.
Est. daily calories needed
Estimated daily caloric requirement (Harris-Benedict x 1.2 activity factor).
Daily protein need
Recommended daily protein in grams (1.0-1.5 g/kg based on nutritional status).
Refeeding syndrome risk
1 = at risk (malnourished + low BMI), 0 = not at elevated risk.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Food Intake Decline = 2, Weight Loss = 3, Mobility = 2, Acute Disease/Stress = 2 = 10 input(s) provided
  2. Calculate MNA-SF score
    MNA-SF score
    14 = 14
  3. Calculate Nutritional status
    1 = 1
  4. Calculate BMI
    BMI
    23.9 = 23.9
