Demura et al used a group of measurements to estimate visceral fat at the L4-L5 level. The authors are from Kanazawa University in Japan.
Measurements included:
(1) anthropometric
(2) ultrasonography
(3) dual-energy X-ray absorptiometry (DXA)
Parameters:
(1) sagittal diameter (between umbilicus and back) in cm (using calipers)
(2) waist circumference (at the level of the umbilicus) in cm
(3) subcutaneous fat thickness over chest in mm
(4) subcutaneous fat thickness over abdomen in mm
(5) subscapular subcutaneous fat thickness in mm
(6) percent segmental fat in the left leg (from 0 to 100)
(7) percent segmental fat in the trunk (from 0 to 100)
visceral fat area at the L4-L5 level in square cm =
= (5.758 * (sagittal diameter)) + (1.688 * (waist circumference)) - (1.303 * (subcutaneous fat thickness chest)) + (0.738 * (subcutaneous fat thickness abdomen)) - (2.007 * (subscapular subcutaneous fat)) - (4.495 * (percent segmental fat left leg)) + (4.904 * (percent segmental fat for trunk)) - 152.23
Performance:
• The percentage of the SEE for the estimate vs CT measurements was around 21%.
