ABSI Score - ABSI Mortality Hazard Levels
| ABSI-z value | Risk |
|---|---|
| Less than -0.868 | Very low |
| Between -0.868 and -0.272 | Low |
| Between -0.272 and +0.229 | Average |
| Between +0.229 and +0.798 | High |
| Greater than +0.798 | Very high |
ABSI z score is calculated based on the ABSI Mean and ABSI SD of the sample individuals of the same age and gender. The ABSI mean and SD data is based on study done by Krakauer NY, Krakauer JC (2012) A New Body Shape Index Predicts Mortality Hazard Independently of Body Mass Index.
ABSI Calculator Details
What is ABSI?
ABSI stands for A Body Shape Index. ABSI is a calculates the health implications of a person’s body height, mass and waist circumference (WC).
How is ABSI calculated?
A Body Shape Index (ABSI) is calculated by dividing waist circumference by its estimate obtained from allometric regression of weight and height.
The equation to calculate ABSI is based on the statistical analysis. With waist (WC) and height in meters and weight in kg, you can use the below equation to calculate ABSI
ABSI = WC/ (BMI(⅔) x Height(½))
where:
- WC – the waist circumference, expressed in m;
- height – expressed in m; and
- BMI (weight / height²) – expressed in kg/m²
ABSIz = (ABSI – ABSImean (age, sex)/(ABSIstd (age, sex))
What is the difference between ABSI and BMI?
The ABSI Index takes into account body weight as well as height and waist circumference as compared to BMI which is based on height and body weight. The inclusion of waist circumference (WC) is make ABSI a better indicator of risk of mortality from excess weight than the BMI( body mass index).
