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.

Evidence over time

Evidence (1)

• Body Composition Assessment by Dual-Energy X-Ray Absorptiometry: A Useful Tool for the Diagnosis of Lipedema — Buso et al. (2022) ✓ verified — consistent · cross sectional · 2022 · reading confidence: high
  The article directly evaluates DXA's ability to differentiate lipedema from controls and characterize its fat distribution, providing specific diagnostic accuracy metrics that support DXA's discriminative role. [grade capped moderate->low per curated Oxford N4]

Context (PECO)

Answers these questions

• Is lipedema underdiagnosed, and can screening tools help identify it? consistent
• What clinical criteria and stage/type classification systems are used to diagnose and grade lipedema, and how reliable are they? refining
• Can MRI, lymphoscintigraphy, or DXA differentiate lipedema from lymphedema and other fat distributions? consistent
• Can DXA (dual-energy X-ray absorptiometry) help identify lipedema fat distribution? consistent
• Can screening tools or questionnaires help identify lipedema cases? consistent
