More about: Katz Index ADL

What it calculates

The “Katz Index ADL” calculator computes Katz ADL Index in points from 6 parameters: bathes independently (1 = yes), dresses independently (1 = yes), uses the toilet independently (1 = yes), transfers from bed and chair independently (1 = yes), continent of urine and stool (1 = yes), feeds self independently (1 = yes).

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

Example calculation

With parameters Bathes independently (1 = yes) = 1, Dresses independently (1 = yes) = 1, Uses the toilet independently (1 = yes) = 1, Transfers from bed and chair independently (1 = yes) = 1, Continent of urine and stool (1 = yes) = 1, Feeds self independently (1 = yes) = 1 the result is 6 points.

How to use

  1. Enter bathes independently (1 = yes), dresses independently (1 = yes), uses the toilet independently (1 = yes), transfers from bed and chair independently (1 = yes), continent of urine and stool (1 = yes) and feeds self independently (1 = yes) — each field above is adjustable with a slider.
  2. Katz ADL Index (points) is calculated automatically as you type.

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.
