Whole Body; Body Composition Analysis

  1. Resource Description
    We assess body composition measures, including fat and lean mass, and rate of change for fat and lean tissue, by DXA. Color images displaying the distribution of fat, lean mass, and bone are provided. Comprehensive adiposity measures (total and regional) include: total body fat, and fat mass index (FMI; fat mass/height<sup>2</sup> ), visceral adipose tissue (VAT), truncal fat, trunk/limb fat mass ratio, % total fat, and % truncal fat/limb fat. We further categorize FMI values by recent thresholds from the NHANES database that are sex, age, and race-specific. Lean body mass measures include lean mass index (LMI; lean mass/height<sup>2</sup> ), appendicular lean mass/height<sup>2</sup> , and regional lean tissue. CV% for fat and lean tissue measures are 1.09 ± 0.15% and 0.89 ± 0.28%, respectively. The whole body bone density reproducibility of least significant change (LSC) at our Core is 0.008 g/cm<sup>2</sup> for males and 0.010 g/cm<sup>2</sup> for females. <img src="https://researchcores.partners.org/data/wiki_pages/155/whole_body_comp_and_bone_density_FINAL.JPG" alt="whole body" style="width:196px;height:142px;"> <a href="https://researchcores.partners.org/data/wiki_pages/155/BODY_COMPOSITION_FINAL.pdf">Example of whole body composition DXA measurement</a> <a href="https://researchcores.partners.org/data/wiki_pages/155/WHOLE_BODY_BMD_FINAL.pdf">Example of whole body bone density DXA measurement</a>
