When testing the belly fat prediction equations in men, the average difference from DXA measurements was small (1.31%), with most predictions falling within a range of -4.08% to 6.71%.

When testing the upper body fat prediction equations in women, the average difference from DXA measurements was small (0.47%), with most predictions falling within a range of -6.43% to 7.38%.

For Chinese men, combining belly fat measurements from a single CT slice at the L1/L2 level with BMI can accurately estimate total body fat, accounting for 83% of the variation seen in DXA scans.

In Chinese men and women, measuring belly fat with QCT scans is closely related to total body fat measured by DXA scans, with the strength of the relationship varying by sex and where the belly scan is taken.

For Chinese women, using belly fat measurements from a CT slice at the L5/S1 level along with body weight can predict total body fat with 81% accuracy compared to DXA scans.

For Chinese men, combining belly fat measurements from a CT slice at the L1/L2 level with BMI can predict upper body fat distribution with 90% accuracy compared to DXA scans.
