研究人员在 2 周内测量了 28 名非肥胖青少年和 27 名肥胖青少年的每日代谢能量摄入量 (ME) 和每日总能量消耗 (TEE)。在非肥胖组和肥胖组中，报告的 ME 均显着 (p < 0.001) 低于测量的 TEE（分别为 2193 .+-. 618 与 2755 .+-. 600 kcal/d 和 1935 .+-. 722 与 3390 .+-. 612 kcal/d）。报告的 ME（TEE 百分比）在肥胖组中显着低于非肥胖组（分别为 58.7 ± 23.6% 和 80.6 ± 18.7%）。当根据身体能量储存的变化对报告的 ME 进行调整时，两组报告的 ME 仍然显着低于 TEE。 ME 在 2 周内具有高度可重复性。对于完成 14 天乳制品的受试者，非肥胖组和肥胖组的组内相关系数分别为 0.87 和 0.89。在两组中，ME 的个体间变异性均显着大于个体内变异性。我们的数据表明，非肥胖和肥胖青少年报告的 ME 并不代表 TEE 或能量需求。
Daily metabolizable energy intake (ME) and total daily energy expenditure (TEE) were measured in 28 nonobese and 27 obese adolescents over a 2-wk period. Reported ME was significantly (p < 0.001) lower than measured TEE in both the nonobese and the obese groups (2193 .+-. 618 vs 2755 .+-. 600 kcal/d and 1935 .+-. 722 vs 3390 .+-. 612 kcal/d, respectively). Reported ME as a percetnage of TEE was significantly lower in the obese than the nonobese group (58.7 .+-. 23.6% vs 80.6 .+-. 18.7%, respectively). When reported ME was adjusted to account for changes in body energy stores, reported ME still remained significantly lower than TEE in both groups. ME was highly reproducible over the 2-wk period. Intraclass correlation coefficients among days for subjects with complete 14-d dairies were 0.87 and 0.89 for nonobese and obese groups, respectively. In both groups, interindividual variability in ME was significantly greater tha intraindividual variability. Our data suggest that reported ME in nonobese and obese adolesents is not representative of TEE or energy requirements.
