About A Body Shape Index (ABSI) Calculator

ABSI Calculator

This on-line ABSI calculator takes your weight, height and waist circumference and calculates the ABSI value.

Using the ABSI calculator

  1. Select the unite of measurement. Either Metric (Kilogram, centimeter, etc..) or U.S.A Standard / Imperial (Pound, Inches, Feet, etc..).
  2. Select the Gender.
  3. Select the Age.
  4. Enter the Height either in centimeters or in feet.
  5. Enter your Weight either in kilogram (kg) or in pounds (lb.).
  6. Enter your Waist Circumference. (Guidelines for measuring waist circumference is given below)
  7. Then, click the Calculate ABSI button. The ABSI value will be calculated and the result will be displayed in the box below the button.

Guidelines for Measuring Waist Circumference

  1. Stand in frond of a tall mirror.
  2. Keep the feet shoulder-width apart.
  3. Wrap the measuring tape around your waist and adjust the tape, so as the bottom edge of the tape is with the top of your hip bones.
  4. Check the mirror and make sure the tape is placed horizontally around your waist.
  5. Take 3 normal breaths.
  6. At the end of the 3rd expiration, slightly tighten the tape and take the measurement.
  7. Repeat the steps 5 and 6 couple of times and take the measurements.
  8. Take the average of the measurements.

A Body Shape Index (ABSI)

To overcome the shortfalls of BMI, Nir Y. Krakauer and Jesse C. Krakauer, studied a sample population of 14,105 adults from USA and came up with A Body Shape Index (ABSI) based on waist circumference, BMI and height. They published their journal at plos.org. This ABSI calculator is developed based on the journal. The below details are also based on the journal.


ABSI Formula

Formla to calculate the ABSI. ABSI is takes waist circumferance as the major factor. ABSI has very little impact for height, weight or BMI.

ABSI = WC / (BMI2/3 * Height1/2)


ABSIz Formula

Formula for calculating ABSI z score. ABSI z score is calculated based on the mean and standard deviations of ABSI calculated for the given age and gender. ABSI z score is used to identiy the premature mortality risk level.

ABSI z score = (ABSI - ABSImean) / ABSISD

  • ABSImean = Mean of calculated ABSI with respect to age and gender.
  • ABSISD = Standard Deviation of calculated ABSI with respect to age and gender.
  • ABSImean and ABSISD are given in the table below.

ABSI Mortality Hazard Levels

The ABSI z score is classified into five premature mortality risk levels.

Quintile ABSIz Score Mortality Risk
1 Less than -0.868 Very Low
2 Between -0.868 and -0.272 Low
3 Between -0.272 and +0.229 Average
4 Between +0.229 and +0.798 High
5 Above +0.798 Very High

Mean and Standard Deviation of ABSI Based on Age and Gender

ABSI z score is calculated based on the ABSIMean and ABSISD of the sample individuals of the same age and gender. This will give the relative score of ABSI.
