Twenty-four-hour energy expenditure (EE) and nonprotein respiratory quotient (RQnp) were measured by indirect calorimetry in 19 upper-body-obese (UBO) and 15 lower-body-obese (LBO) women with similar body mass index (BMI) and body fat percent. The measurements were performed in a respiration chamber on a predetermined physical activity program and a controlled diet. No differences between the UBO and LBO groups were found in 24-hour, daytime, and sleeping EE after adjustment for differences in fat-free mass (FFM). Furthermore, no group effect was observed in RQnp, but a positive correlation was found between RQnp and age. Despite the fact that an increased free fatty acid (FFA) turnover has been found in UBO subjects, the present study does not support the contention that upper-body obesity is accompanied by an increased lipid oxidation.
通过间接测热法，对19名上身肥胖（UBO）和15名下身肥胖（LBO）且体重指数（BMI）和体脂百分比相似的女性进行了24小时能量消耗（EE）和非蛋白呼吸商（RQnp）的测量。测量在呼吸室内按照预定的体力活动计划和控制饮食进行。在对去脂体重（FFM）差异进行调整后，UBO组和LBO组在24小时、白天和睡眠EE方面未发现差异。此外，在RQnp方面未观察到组间效应，但RQnp与年龄之间存在正相关。尽管在上身肥胖受试者中发现游离脂肪酸（FFA）周转率增加，但本研究不支持上身肥胖伴有脂质氧化增加的观点。
