综述目的：最近的研究表明，黑人的能量消耗低于白人。许多研究人员推测，这就是为什么黑人女性比白色女性肥胖率更高的原因。这些发现启动了许多关于种族作为肥胖的主要生物决定因素和能量消耗作为潜在途径的研究。种族是一个很难构建使用在biomedical research.Recent Findings：最近的研究结果包括：一个较低的静息能量消耗的解释观察到的黑人成年人，数据显示，相对静息能量消耗可能不是一个显着的预测体重变化的非洲裔人口，和不一致的数据活动能量消耗的作用作为一个决定因素的儿童的体重变化。这些数据表明，黑人个体的静息能量消耗和活动能量消耗可能低于白色个体。较低的静息能量消耗可能是由于高代谢活性器官的质量较小所致。在黑人中，体重增加不太可能与较低的静息能量消耗或活动有关，因为在人群中没有发现相关性。在临床上，重要的是要关注个人可改变的风险因素，例如，能量摄入和身体活动水平。
PURPOSE OF REVIEW: Recent studies have suggested that black individuals have lower energy expenditure than whites. Many investigators hypothesized that this is why black women experience higher rates of obesity than white women. These findings initiated much research on race as a primary biological determinant of obesity and energy expenditure as a potential pathway. Race is a difficult construct to use in biomedical research.RECENT FINDINGS: Recent findings have included: an explanation for the lower resting energy expenditure observed among black adults, data showing that relative resting energy expenditure may not be a significant predictor of weight change in African-origin populations, and inconsistent data on the role of activity energy expenditure as a determinant of children's weight change.SUMMARY: The data suggest that black individuals have lower resting energy expenditure and possibly activity energy expenditure than white individuals. The lower resting energy expenditure is probably caused by a smaller mass of high metabolically active organs. It is unlikely that increased weight gain is associated with lower resting energy expenditure or activity among blacks, because no association has been found within populations. Clinically, it is important to focus on personal modifiable risk factors, e.g., energy intake and physical activity levels.
