Table 2 Ultrasound-derived adiposity variables

A-L

(MsAa + MiA)/MsL

Abdominal-to-lumbar adiposity ratio (total subcutaneous and visceral abdominal adiposity thickness relative to lumbar adiposity thickness)

S-M

(MsAa + MsSI + MsL)/weight

Subcutaneous adiposity to mass ratio (total subcutaneous trunk adiposity thickness relative to overall body mass)

V-M

(MppA + MiA)/weight

Visceral adiposity to mass ratio (total visceral trunk adiposity thickness relative to overall body mass)

MAR-A

MsAa/MiA

Maximal abdominal ratio A (ratio between subcutaneous and visceral abdominal adiposity)

A-L/BMI

[(MsAa + MiA)/MsL]/[weight/(height x height)]

Abdominal-to-lumbar adiposity ratio to BMI (ratio between abdominal and lumbar adiposity thickness relative to overall body mass index

A-L/WHR

[(MsAa + MiA)/MsL]/(waist circumference/hip circumference)

Abdominal-to-lumbar adiposity ratio to WHR (ratio between abdominal and lumbar adiposity thickness relative to the ratio between waist and hip circumferences)

TC-TBA

(MsAa + MsSI + MsL)/total body adiposity percentage

Total circumference to total body adiposity ratio (total trunk circumference thickness relative to total body adiposity percentage)
