The aim of this study was to investigate the abdominal visceral fat accumulation and the association between visceral fat and the severity in COPD patients. We performed clinical and laboratory tests, including pulmonary function test in COPD patients (n=188) and control, which included subjects without airflow obstruction (n=48). We used body mass composition scale to evaluate the body mass index (BMI), skeletal muscle mass (SMM), abdominal visceral fat area (VFA), subcutaneous fat area (SFA). The COPD group had a larger VFA than the control group. The prevalence of non-obese subjects with an increased VFA was greater in the GOLD (Global Initiative for Chronic Obstructive Lung Disease) Stages I and II than in other stages of COPD. All parameters measured by bioelectrical impedance-meter were inversely correlated with severity of disease.
