ABSI Calculator

How to calculate ABSI Calculator?

ABSI (A Body Shape Index) relates waist circumference to BMI and height to provide an estimate of health risk associated with body shape.

Key formula: ABSI = WC / (BMI^(2/3) * height^(1/2)) where WC = waist circumference (m), height = height (m), BMI = weight / height².

Using the ABSI Calculator calculator: an example

Example inputs: height 175 cm, weight 85 kg, waist 94 cm.

Step-by-step calculation:

• Convert measurements: height = 175 cm → 1.75 m; waist = 94 cm → 0.94 m.
• Calculate BMI: BMI = 85 / (1.75²) ≈ 27.8 kg/m².
• Compute denominator: BMI^(2/3) × height^(1/2) ≈ 27.8^(2/3) × √1.75 ≈ 9.17 × 1.32 ≈ 12.13.
• Calculate ABSI: 0.94 / 12.13 ≈ 0.0775 (example result).

Frequently Asked Questions

What does a higher ABSI mean?

A higher ABSI indicates relatively greater abdominal fat for a given BMI and height and is associated with increased mortality risk in population studies.

Are units important when calculating ABSI?

Yes. Use meters for height and waist and kilograms for weight; mixing units (cm vs m) will produce incorrect results.

Can ABSI replace BMI?

No. ABSI complements BMI by capturing body shape and abdominal adiposity; use both metrics together for a more complete risk assessment.
