Waist-to-Hip Ratio (WHR) Concept
The waist-to-hip ratio (WHR) is an anthropometric index that measures the proportion between the circumference of the waist and that of the hips.
The BMI was created in 1832 by the Belgian mathematician and statistician Adolphe Quetelet, who, through anthropometric studies, observed that weight increases with the square of height19. The physiologist Ancel Keys then took up this indicator in the 1970s, calling it "Body Mass Index" and using it in studies on obesity.
Calculation Formula
The Waist-to-Hip Ratio (WHR) is calculated with the following formula:
$$ \textcolor{var(--primary-color)}{\displaystyle \Large \textbf{WHR} = \frac{Waist}{Hip}} $$
Where:
- WHR = Waist-to-Hip Ratio
- Waist = Waist measurement in meters
- Hip = Hip measurement in meters
For example, if a person has a waist circumference of 75 cm and a hip circumference of 95 cm, his or her WHR will be approximately 0.7912.
Importance of the Waist-to-Hip Ratio
The WHR is used as an indicator of health and disease risk, particularly to assess body fat distribution. A high WHR is associated with an increased risk of conditions such as cardiovascular disease, type 2 diabetes, and other obesity-related diseases. Guidelines suggest that the WHR should be less than 0.8 in women and 0.9 in men to reduce the risk of these diseases.
Associated Risks
| Women WHR Value | Men WHR Value | Health Risk |
|---|---|---|
| Less than 0.80 | Less than 0.95 | Low |
| Between 0.80 and 0.85 | Between 0.90 and 1.00 | Moderate |
| Greater than 0.85 | Greater than 1.00 | High |

Anthropometric Indicators
Waist-Hip Ratio (WHR), A Body Shape Index (ABSI), and Body Mass Index (BMI) are three anthropometric indicators used to assess body composition and health risk. The commonalities between these three indices are:
-
They measure body fat distribution
All three indices attempt to assess the amount and distribution of fat in the body, although with different approaches.
-
They assess health risk
They are used to estimate the risk of developing diseases such as cardiovascular disease, diabetes, and other obesity-related conditions.
-
They use simple anthropometric measures
They require basic measurements of the human body, such as height, weight, waist circumference, and hip circumference.
-
They are screening tools
They do not provide a clinical diagnosis, but serve as indicators to identify people who may be at risk and require further medical evaluation.
Comparison of WHR, ABSI and BMI
| Indicator | What it measures | Advantages | Disadvantages | Calculator |
|---|---|---|---|---|
| BMI | Weight for height | Easy to calculate, useful for populations | Does not distinguish between fat and muscle | BMI Calculator |
| WHR | Body fat distribution | More predictive of cardiovascular risk than BMI | Does not take height or muscle mass into account | WHR Calculator |
| ABSI | Abdominal fat distribution | More accurate at predicting mortality risk than BMI | More complex calculation | ABSI Calculator |
Professional Papers and Relevant Studies
Numerous scientific studies and professional papers have examined the WHR as a health indicator. Among the most significant:
- "Waist circumference and waist-to-hip ratio as predictors of cardiovascular events" - This study analyzes the importance of the WHR in predicting cardiovascular events and suggests that it may be a more accurate indicator than body mass index (BMI).
- European guidelines - Recommend the use of the WHR in the assessment of cardiovascular risk and in the monitoring of general health.
- Clinical Studies - Research has shown that a high WHR is associated with increased mortality and chronic disease.
WHR is therefore a useful tool not only for assessing body composition but also for preventing obesity-related diseases.
Summary
The concept of waist-to-hip ratio (WHR) has been widely studied as a risk indicator for cardiovascular events. Here is a summary of the main findings regarding WHR and waist circumference (WC) as predictors of cardiovascular disease.
Use this calculator to monitor your ABSI and, if necessary, consult a health professional for a more in-depth assessment!
Use
First, choose the calculation with the Metric or Imperial System.
Enter the values for Waist Circumference and Hip.
If the chosen system is the Metric System then the Waist Circumference will be in Centimeters and the Hip will be in Centimeters.
If the chosen system is the Imperial System then the Waist Circumference will be in Inches and the Hip will be in Inches.
By entering your Waist Circumference and Hip it calculates your WHR.
