Differences in Abdominal Body Composition According to Glycemic Status: An Inverse Probability Treatment Weighting Analysis.

Background: Several studies have reported that abdominal fat and muscle changes occur in diabetic patients. However, there are few studies about such changes among prediabetic patients. In this study, we evaluated the differences in abdominal fat and muscles based on abdominopelvic computed tomography in prediabetic and diabetic subjects compared to normal subjects.

Intramuscular and Intermuscular Abdominal Fat Infiltration in COPD: A Propensity Score Matched Study.

Purpose: Low-attenuation muscle area (LAMA) and normal-attenuation muscle area (NAMA) indicate lipid-rich and lipid-poor skeletal muscle areas, respectively. Additionally, intermuscular adipose tissue (IMAT) indicates localized fat between muscle groups.
