对体重指数(BMI)和体脂百分比相近的19例上体肥胖者(UBO)和15例下体肥胖者(LBO)的24小时能量消耗(EE)和非蛋白呼吸商(RQnp)进行了间接热法测定。测量是在呼吸室中进行的，按照预定的体力活动计划和控制的饮食进行。在调整了脱脂体重(FFM)的差异后，UBO组和LBO组之间在24小时、白天和睡眠EE方面没有发现差异。此外，RQnp没有观察到群体效应，但RQnp与年龄呈正相关。尽管在UBO受试者中发现了游离脂肪酸(FFA)周转增加的事实，但目前的研究并不支持上半身肥胖伴随着脂质氧化增加的论点。
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 RQnpand 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.
