Frequently asked questions

What is a normal Conicity Index?
Most adults fall between about 1.0 and 1.5. Thresholds differ between studies and populations, so the index is best used to track change over time rather than as a hard cut-off.
How is the Conicity Index different from waist-to-hip ratio?
The C-Index uses weight and height instead of a hip measurement, so it describes abdominal shape relative to overall body size without needing a second circumference.
Why is there a 0.109 constant?
0.109 comes from the geometry of the reference cylinder and makes the index unitless so values are comparable across people.
