Excessive amount of visceral fat is considered as a crucial indicator for the metabolic syndrome (MS). Visceral fat area (VFA) at the umbilicus level measured by CT is adopted as the gold standard, but it has many limitations. Recently, Application of bioelectrical impedance analysis (BIA) for measuring VFA is widely used. However, the correlation between impedance and VFA is highly dependent on the measurement conditions. Therefore, we evaluate its measurement conditions here. In our experiment, we choose 5 different electrode configurations with changes of current and its frequency for evaluating its performance to distinguish fat and thin group with impedance. Our results indicated that electrode arrangement with fixed waist ratio is better in its performance than fixed distance electrode arrangement. Current electrode on each flank side is better than on the front and rear side. Shorter distance between current electrode and voltage electrode is better than longer distance in its performance. Our experiment results are presented.
过量的内脏脂肪被认为是代谢综合征(MS)的关键指标。通过CT测量的脐水平内脏脂肪面积(VFA)被用作金标准,但它有许多局限性。近年来,生物电阻抗分析(BIA)在测量VFA中的应用被广泛使用。然而,阻抗与VFA之间的相关性高度依赖于测量条件。因此,我们在此评估其测量条件。在我们的实验中,我们选择了5种不同的电极配置,改变电流及其频率,以评估其通过阻抗区分胖瘦组的性能。我们的结果表明,固定腰比的电极排列在性能上优于固定距离电极排列。两侧的电流电极比前后侧的更好。电流电极和电压电极之间较短的距离在性能上优于较长的距离。我们展示了实验结果。
