[1] [2] The degree of circularity of an ellipse is quantified by eccentricity, with values between 0 to 1, where 0 is a perfect circle (waist circumference same as height) and 1 is a vertical line. [1] To accommodate human shape data in a greater range, Thomas and colleagues mapped eccentricity in a range of 1 to 20 by using the equation: [1]
[3] [4] [1] The test is most commonly performed by placing the stethoscope below the xiphoid process and lightly scratching the skin parallel to the expected liver edge. The examiner begins scratching in the right lower quadrant of the abdomen along the midclavicular line and moves superiorly until the sound abruptly increases in volume. This ...
For persons of normal BMI, SAD should be under 25 centimetres (9.8 in). When this measure exceeds 30 centimetres (12 in) it correlates to increased cardiovascular risk and insulin resistance. [2] For men in their 40s, a SAD greater than 25 cm also predicts significantly higher risk of developing Alzheimer's disease 30 years later. [4]
An abdominal examination is a portion of the physical examination which a physician or nurse uses to clinically observe the abdomen of a patient for signs of disease. The abdominal examination is conventionally split into four different stages: first, inspection of the patient and the visible characteristics of their abdomen.

A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).
