The influence of body composition, resting metabolic rate (RMR), and sex on variation in total energy expenditure (TEE) was examined by using meta-analysis (13 published studies in a total of 162 adults). TEE (10.9 +/- 3.2 MJ/d) was significantly correlated with body mass (BM; weighted mean converted r = 0.68, P < 0.05) and resting metabolic rate (RMR; weighted mean converted r = 0.66, P < 0.05). The correlation coefficients, regression coefficients, and intercepts for the regression between TEE and RMR and between TEE and BM were highly variable between studies. When TEE was adjusted for RMR, there was no significant correlation with body fat, and females had a significantly lower TEE than males by 1.1 MJ/d (P = 0.005). We conclude that 1) the relationships between TEE and RMR and TEE and BM are highly variable between studies with nonzero intercepts, precluding use of the traditionally used ratios of TEE to RMR or TEE to BM for data comparison; 2) after adjustment of TEE for RMR, TEE is not associated with adiposity, and women have a significantly lower TEE than men; and, 3) there are insufficient published data to develop prediction models for TEE in adults.
通过荟萃分析（共162名成年人的13项已发表研究），研究了身体成分、静息代谢率（RMR）和性别对总能量消耗（TEE）变化的影响。TEE（10.9±3.2 MJ/天）与体重（BM；加权平均转换r = 0.68，P < 0.05）和静息代谢率（RMR；加权平均转换r = 0.66，P < 0.05）显著相关。TEE与RMR以及TEE与BM之间回归的相关系数、回归系数和截距在各研究之间差异很大。当对TEE进行RMR校正后，与体脂无显著相关性，且女性的TEE显著低于男性，相差1.1 MJ/天（P = 0.005）。我们得出以下结论：1）TEE与RMR以及TEE与BM之间的关系在各研究之间差异很大，截距非零，因此不能使用传统的TEE与RMR或TEE与BM的比值进行数据比较；2）对TEE进行RMR校正后，TEE与肥胖无关，且女性的TEE显著低于男性；3）公开数据不足以建立成年人TEE的预测模型。
