| Outline of Final Research Achievements |
We observed changes in anthropometric and body composition data over a period of 6 months in 68 patients with T2DM. All patients received intensive medical therapy and lifestyle modification, including hospitalization. Visceral fat area (VFA, cm2) and appendicular lean soft tissue (ALST, kg) mass was calculated. Multivariate linear regression analysis revealed that the change in body weight was positively associated with both the changes of VFA and ALST mass. Notably, baseline VFA was an independent positive predictor of the changes in ALST after adjusting for confounding factors such as age, gender, body composition parameters, and A1c. This study revealed that visceral fat accumulation was associated with changes in skeletal muscle mass. These results suggest that visceral fat is predominantly reduced compared with skeletal muscle during weight reduction programs in T2DM patients with visceral obesity.
