Clasey et al reported equations for estimating abdominal visceral fat in adults. The authors are from the University of Virginia at Charlottesville.
Patient selection: adult from 20 to 80 years of age
Reference method: abdominal CT
Parameters:
(1) sex
(2) waist circumference in cm
(3) abdominal sagittal diameter in cm (anthropometric) at umbilicus

AVF in square cm

Other measures studied but less accurate:
(1) body mass index
(2) waist to hip ratio (WHR)
(3) hip circumference in cm
Equations using DXA of trunk or abdominal fat were comparable to waist circumference and abdominal sagittal diameter.
