Let's say that you took the measurement of how thick a person's torso is; specifically, by measuring between the following two points:
- the skin on their chest, slightly above the navel
- the skin on their back, just outside the spine
This is NOT a measurement of hip or waist circumference, or of how wide across someone is at the hip or the waist Basically, imagine making a measurement between the points indicated in the two circles below.
This measurement provides a rough way to extract hip circumference from hip diameter, since a cross-section of the human trunk/torso region can be approximated as an ellipse.
Google gets plenty of studies on how thick certain organs are, or how wide a person is across the hips, but none about this specific bodily dimension.
I Googled "front-to-back width", "torso thickness", "how thick is the human body", etc., and also tried to figure this out via adding up the depth of the abdominal cavity, the diameter of the spine, the thickness of the skin, etc.
Is there a medical or clinical term for this type of measurement?
