What it calculates

The “BASDAI” calculator computes BASDAI from 6 parameters: fatigue, tiredness (0–10), neck, back or hip pain (0–10), pain or swelling in other joints (0–10), discomfort from areas tender to touch or pressure (0–10), morning stiffness severity (0–10), morning stiffness duration (0–10; 10 = 2 h or more).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Fatigue, tiredness (0–10) = 6, Neck, back or hip pain (0–10) = 5, Pain or swelling in other joints (0–10) = 3, Discomfort from areas tender to touch or pressure (0–10) = 4, Morning stiffness severity (0–10) = 6, Morning stiffness duration (0–10; 10 = 2 h or more) = 4 the result is 4.6.

How to use

Enter fatigue, tiredness (0–10), neck, back or hip pain (0–10), pain or swelling in other joints (0–10), discomfort from areas tender to touch or pressure (0–10), morning stiffness severity (0–10) and morning stiffness duration (0–10; 10 = 2 h or more) — each field above is adjustable with a slider.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
