ObjectiveThe purpose of this study was to determine reproducibility and clinical thresholds for DXA-derived visceral adipose tissue (VAT).Design And MethodsThe sample included 2317 white and African American adults 18-74 years of age. VAT areas (cm(2) ) were measured using a Hologic DXA scanner equipped with APEX 4.0 software. Reproducibility was assessed using repeated measurements on 101 participants scanned 14 days apart. Receiver Operating Characteristic (ROC) curves were used to assess clinical utility and select thresholds that identified elevated cardiometabolic risk, defined as the presence of ≥2 risk factors.ResultsReproducibility of DXA-VAT was 8.1%. The areas under the ROC curves ranged from 0.754 in African American men to 0.807 in white women. The thresholds were higher in white men (154 cm(2) ) and women (143 cm(2) ) compared to African American men (101 cm(2) ) and women (114 cm(2) ).ConclusionThe results demonstrated that DXA VAT is a useful clinical marker of cardiometabolic risk; however, further research is required to determine associations with health outcomes using longitudinal studies.Copyright © 2013 The Obesity Society.
