Many of the Fit Grader assessments determine girth measurements for several body parts. The relationship and/or ratio of these have been shown to correlate to increased/decreased odds for developing various diseases. They can also be used to estimate lean body mass and are a simple way to track changes over time.
Following are the scoring standards we follow broken down by gender and age.
Waist to Hip Relation Score – Risk Level
Persons with extra weight located around the middle are at higher risk for diseases such as heart disease and diabetes than those who carry weight around their hips and thighs. Abdominal fat, when out of proportion to total body fat, may be considered an indicator of health risks.

Waist to Height Ratio – Risk Level
The degree of central fat distribution may be more closely tied to metabolic risks than BMI. Measurement of the degree of central fat distribution thus appears to be important for the early detection of subsequent health risks, even among those of normal weight.
