摘要Objective To investigate the relationship between resting energy expenditure (REE) and patterns of obesity/regional fat parameters in Chinese adults. Methods Body mass index (BMI), fat mass (FM), fat-free mass (FFM) were assessed in 109 Chinese adults (52 men and 57 women), and their abdominal visceral adipose tissue area (VA) and subcutaneous fat area (SA) were measured using magnetic resonance imaging (MRI) measurements. REE was measured with indirect calorimetry and compared with normal and obese subjects. Multivariate analysis was used to study the factors related to REE. Results The resting energy expenditure per kilogram of body weight (REE/kg) was closely related with the area of abdominal visceral fat measured with MRI. REE/kg was significantly lower in overweight/obesity subjects than in normal-weighted subjects, and significantly lower in subjects with abdominal obesity (VA≥100 cm2) than in subjects with non-abdominal obesity (VA＜ 100 cm2, BMI≥25 kg/m2). In the stepwise regression analysis of REE/kg on regional fat parameters, VA in men and women and SA in women were independent factors reversely related to REE/kg. Conclusion REE/kg is associated with the visceral fat area and more prominent in men. REE/kg can be used as an index in the pathophysiology of intra-abdominal obesity.
