身体组成通常旨在定量估计脂肪量，不足以评估营养状态，另一方面，营养状态由细胞内/细胞外质量比例（ECM/ECM）明确定义。使用相敏生物电阻抗分析仪进行的直接测量可用于定义正常和异常人群中的电流分布。相位角和电抗列线图直接反映了ECM/ECM通路的比例，体阻抗分析（BIA）也被验证可以估计个体体细胞质量（ECM）的含量。一个新的身体细胞质量指数（BCMI）获得除以体重公斤的身体面积平方米面临的散点图分布的相位角和电抗值从控制和患者，并提出作为一种定性的方法来识别异常ECM/ECM比值和营养状态。
Body composition is generally aiming at quantitative estimates of fat mass, inadequate to assess nutritional states that on the other hand are well defined by the intra/extra cellular masses proportion (ECM/BCM). Direct measures performed with phase sensitive bioelectrical impedance analyzers can be used to define the current distribution in normal and abnormal populations. Phase angle and reactance nomogram is directly reflecting the ECM/BCM pathways proportions and body impedance analysis (BIA) is also validated to estimate the individual content of body cell mass (BCM). A new body cell mass index (BCMI) obtained dividing the weight of BCM in kilograms by the body surface in square meters is confronted to the scatterplot distribution of phase angle and reactance values obtained from controls and patients, and proposed as a qualitative approach to identify abnormal ECM/BCM ratios and nutritional states.
