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.
Scientific Claim
In Chinese women, a prediction equation using L5/S1 abdominal QCT fat percentage and body mass explains 81% of the variance in total body fat percentage measured by dual-energy X-ray absorptiometry (DXA).
Original Statement
“L5/S1%fat 0.52 × L5/S1%fat + 0.16 × weight-3.52 0.81 2.73”
