**ABSI (A Body Shape Index)** is a novel anthropometric measure that was developed to predict mortality risk and improve health outcomes. This measure provides a better understanding of a person's body shape and the associated health risks. In this article, we will discuss what ABSI is, how to interpret it, and how to calculate it with examples.

## What is ABSI?

ABSI is a measure of a person's body shape that takes into account their height, weight, and waist circumference. This index was developed by Dr. Nir Krakauer and his team in 2012. ABSI is based on the assumption that the distribution of body mass, especially the excess body fat, is a better predictor of mortality than just the overall body mass index (BMI).

BMI is a widely used measure to determine whether a person is overweight or obese. However, BMI does not take into account the distribution of fat in the body. ABSI is a better indicator of health risk because it takes into account both weight and waist circumference.

## How to Calculate ABSI

The ABSI formula is relatively simple and can be calculated using the following equation:

$ABSI=\frac{WC}{BM{I}^{\frac{2}{3}}\times heigh{t}^{\frac{1}{2}}}$Where:

**WC**is waist circumference in meters,**BMI**is body mass index,- and
**height**is in meters.

To calculate ABSI, you need to first measure your waist circumference and your height in meters. Then calculate your BMI by dividing your weight in kilograms by the square of your height in meters. Finally, use the above equation to calculate your ABSI.

## How to Interpret ABSI

ABSI is a dimensionless index, which means that it does not have any units. A higher ABSI score indicates a higher risk of mortality. ABSI can be used as a screening tool to identify individuals at higher risk for cardiovascular disease and other health problems.

A person's ABSI score can be compared to the average ABSI score of the population to determine if they are at a higher risk of health problems. The ABSI score can also be used to monitor changes in a person's health status over time.

## Example Calculation

Let's say that John weighs 85 kg, his height is 1.8 meters, and his waist circumference is 90 cm. To calculate his ABSI, we need to follow the following steps:

- Convert the waist circumference to meters: 90 cm = 0.9 meters
- Calculate John's BMI: BMI = 85/(1.8^2) = 26.2 kg/m^2
- Use the ABSI formula to calculate John's ABSI: ABSI = 0.9/(26.2^(2/3) * (1.8)^1/2) = 0.076

John's ABSI score is 0.076 (check with the ABSI calculator ), which indicates that he is at a **lower risk of mortality** compared to the average ABSI score of the population.

## Conclusion

ABSI is a measure of a person's body shape that takes into account their height, weight, and waist circumference. This index provides a better understanding of a person's body shape and the associated health risks. ABSI is a useful tool to identify individuals at a higher risk of health problems, including cardiovascular disease. The calculation of ABSI is relatively simple and can be done using a person's waist circumference, height, and BMI.
