In a DXA body composition study, the leg fat mass/total fat mass index distinguished lipedema patients from healthy controls with AUC=0.90 (sensitivity 0.95, specificity 0.73 at cutoff 0.383) across all BMI strata, with elevated leg fat proportion (0.451 vs 0.354) and inverted trunk/legs ratio (0.960 vs 1.502), while appendicular lean mass and total bone density did not differ.
