营养状况是营养素摄入、吸收和利用的结果，能够影响生理和病理状态。可以使用不同的技术测量个体的营养状况，例如 CT 身体成分、定量磁共振成像、超声波、双能 X 射线吸收测定法和生物阻抗。由于肥胖正在成为世界范围内的流行病，人们越来越关注通过研究身体成分来监测肥胖相关疾病的状况并延缓其发展。这些证据的出现表明需要根据体重变化对营养状况进行标准评估，这在多种临床环境中发挥着重要作用，例如组织及其身体成分波动的定量测量、存活率、病理状况和疾病。由于体重指数已被证明是对无脂和脂肪量、体细胞量和液体的不精确测量，如果体重变化则无法提供任何信息，因此需要找到一种更好的方法来评估身体成分，以便评估随体重增加和减少以及衰老过程中的无脂和脂肪量。监测身体成分对于营养和医疗干预非常有用。本综述的重点是身体成分在临床实践中的应用。 (C) 2016 Elsevier Ireland Ltd. 保留所有权利。
Nutritional status is the results of nutrients intake, absorption and utilization, able to influence physiological and pathological conditions. Nutritional status can be measured for individuals with different techniques, such as CT Body Composition, quantitative Magnetic Resonance Imaging, Ultrasound, Dual Energy X-Ray Absorptiometry and Bioimpendance. Because obesity is becoming a worldwide epidemic, there is an increasing interest in the study of body composition to monitor conditions and delay in development of obesity-related diseases. The emergence of these evidence demonstrates the need of standard assessment of nutritional status based on body weight changes, playing an important role in several clinical setting, such as in quantitative measurement of tissues and their fluctuations in body composition, in survival rate, in pathologic condition and illnesses. Since body mass index has been shown to be an imprecise measurement of fat-free and fat mass, body cell mass and fluids, providing no information if weight changes, consequently there is the need to find a better way to evaluate body composition, in order to assess fat-free and fat mass with weight gain and loss, and during ageing. Monitoring body composition can be very useful for nutritional and medical interventional. This review is focused on the use of Body Composition in Clinical Practice. (C) 2016 Elsevier Ireland Ltd.
