A Body Shape Index (ABSI) is a measure of body size and shape that takes into account an individual's height, weight, and waist circumference.

It is similar to the Body Mass Index (BMI) in that it is a tool used to estimate an individual's overall health and risk for obesity-related health problems.

However, ABSI is believed to be a more accurate measure of an individual's risk for obesity-related health problems because it takes into account the distribution of an individual's body fat, which may be more important for determining health risks than overall weight or BMI. Some research suggests that ABSI may be more predictive of morbidity and mortality than BMI, although more research is needed to confirm this.

### The ABSI formula :

The Body Shape Index (ABSI) is a formula that takes into account the distribution of body fat and not just weight or Body Mass Index (BMI) to determine body shape. The formula is:

ABSI = WC / BMI2/3 x Height1/2

Where:

• Waist Circumference : is measured in centimeters Height is measured in meters
• Height : is measured in meters
• BMI : is calculated as weight (in kilograms) divided by height (in meters) squared (kg/m2)
• BMI = Weight / Height2

The ABSI is a dimensionless number and it's not affected by changes in weight or height. The ABSI values are compared to a reference population and can be used to determine the risk of obesity-related diseases.

It's important to note that this formula is a research-based tool and not a diagnostic tool. It's best to consult a healthcare professional to determine if you're at risk for any obesity-related diseases.

### The ABSI z-score formula :

The ABSI z-score is a way to interpret the Body Shape Index (ABSI) values in relation to a reference population. The formula to calculate the ABSI z-score is:

ABSIz score = ABSI - ABSImean / ABSISD

Where:

• ABSI : is the Body Shape Index calculated using the formula provided earlier.
• Mean ABSI : is the average ABSI value for the reference population.
• Standard Deviation ABSI : is the measure of how much the ABSI values vary from the mean in the reference population.

The z-score represents how many standard deviations away from the mean an individual's ABSI value is. A positive z-score indicates that the individual's ABSI value is higher than the mean and a negative z-score indicates that the individual's ABSI value is lower than the mean.

ABSI z-score can be used to determine if an individual is at risk of obesity-related diseases, with higher values indicating a greater risk. It's important to note that this formula is a research-based tool and not a diagnostic tool. It's best to consult a healthcare professional to determine if you're at risk for any obesity-related diseases.

### How to Measure Waist Circumference

Measuring your waist circumference is a simple and easy way to track your progress and monitor your health. Here are the steps to measure your waist circumference:

1. Find your natural waistline. This is typically located above your belly button and below your ribcage.
2. Place a measuring tape around your waist at this point, making sure the tape is level and not too tight or too loose.
3. Take the measurement in inches or centimeters, and make sure to breathe normally while measuring.
4. Record the measurement and repeat the process at least twice to ensure accuracy.

It's important to note that men's waist circumference should be measured at the level of the navel and women's at the level of the natural waistline, which is at the narrowest point of the torso.

It's also recommended to measure your waist circumference at the same time of the day, in the same clothing and in the same position to get the most accurate measurement.

### Pros and downsides of a Body Shape Index

Body Shape Index (ABSI) has some pros and cons that are worth considering:

Pros:

• ABSI takes into account the distribution of body fat, rather than just weight or BMI, to determine body shape.
• ABSI values are compared to a reference population and can be used to determine the risk of obesity-related diseases.
• ABSI is a dimensionless number and is not affected by changes in weight or height.

Downsides:

• ABSI is a relatively new measurement and is not yet widely used or understood by healthcare professionals.
• ABSI is a research-based tool and not a diagnostic tool, so it should be used in conjunction with other clinical parameters and lifestyle information to determine risk.
• ABSI z-score can be affected by factors such as age, sex and ethnicity, so it's recommended to use the z-score within the same population.

It's important to note that ABSI is a research-based tool and not a diagnostic tool. It's best to consult a healthcare professional to determine if you're at risk for any obesity-related diseases and to use it in conjunction with other clinical parameters, as well as lifestyle and clinical examination. Additionally, ABSI should be used as an additional tool to other measurements such as BMI, waist circumference and body fat percentage, to obtain a more comprehensive view of body composition.

The ABSI z score is a measure of how an individual's ABSI compares to the general population. It is calculated by subtracting the mean ABSI of the population from an individual's ABSI and dividing the result by the standard deviation of the population's ABSI.

The ABSI z score is expressed in standard deviation units and can be used to assess an individual's risk for obesity-related health problems. A positive ABSI z score indicates that an individual's ABSI is higher than the average for the population, while a negative ABSI z score indicates that it is lower.
