Supine Abdominal Height

The term Supine Abdominal Height "is a measure of the girth around the abdomen at a height that is half way between the top of your pelvis and your lower ribs. It is considered a more reliable measure of a person's girth than the waistline, and the measurement is taken by a health professional using a caliper". It has been used to predict morality in men.

Apparently, the definition is similar to Sagittal Abdominal Diameter.
