A Useful Tool As a Medical Checkup in a General Population—Bioelectrical Impedance Analysis

Abstract

Accumulation of visceral fat leads to metabolic syndrome and increases risks of cerebro-cardiovascular diseases, which should be recognized and improved at the early stage in general population. Accurate measurement of visceral fat area (VFA) is commonly performed by the abdominal cross-sectional image measured by computed tomography scan, which is, however, limited due to the radiation exposure. The bioelectrical impedance analysis (OMRON, HDS-2000 DUALSCANR) has been recently developed to measure VFA, which is more easily accessible modality. In the present study, we investigated the clinical usefulness of DUALSCANR in 226 subjects who received health examination, including blood chemistries, electrocardiography, cardio, and carotid ultrasonography. VFA was measured within only just 5 min. Average of VFA was 83.5 ± 36.3 cm2 in men, and 64.8 ± 28.0 cm2 in women, which was correlated to weight (r = 0.7404, p < 0.0001), body mass index (BMI) (r = 0.7320, p < 0.0001), and waist circumstance (r = 0.7393, p < 0.0001). In multivariate analyses, VFA was significantly associated with weight (p < 0.0001), BMI (p < 0.0001), and waist circumstance (p < 0.0001). Compared to the group of smaller waist and normal BMI, VFA was significantly increased (p < 0.0001) in the group of larger waist and obese subjects. In conclusion, these results indicated that DUALSCANR is useful to measure VFA easily in general population, even in a large number of subjects.

Efficacy of visceral fat estimation by dual bioelectrical impedance analysis in detecting cardiovascular risk factors in patients with type 2 diabetes

“…In this study, performing dual BIA and CT on the same day increased the robustness of our findings. In previous studies about general population, VFA estimated by impedance analysis correlated with VFA estimated by CT [26–30] and also correlated with parameters of obesity such as BMI, waist circumference and waist-hip ratio [31]. Gomez et al and Park et al reported bioimpedance analysis tends to underestimate VFA compared with CT [27–30].…”

Membrane Capacitance from a Bioimpedance Approach: Associations with Insulin Resistance in Relatively Healthy Adults

“…However, after fully adjusting for covariates, only the association with waist circumference in both sexes and glucose among women remained significant. Several studies have reported an association between MetS and the phase angle, and MetS has been linked to disturbances of the cell membrane and its surrounding milieu (28,29). One explanation for the difference in our study is that our MetS groups were relatively small.…”

“…Therefore, it is plausible that these factors would lead to higher C M in those with IR (31‐33). Some conditions that are comorbid to IR, such as those of MetS, may exert similar effects on the membrane (28,29). Therefore, future studies are needed to examine the specific mechanisms by which IR would influence C M and determine the sensitivity and specificity of the association between C M and IR.…”

Optimal Cut-Off Values of Visceral Fat Area for Predicting Metabolic Syndrome Among Type 2 Diabetes Patients in Ningbo, China

“…The measurements of body site for VFA and SFA were measured at the level of umbilicus with a visceral fat analyzer (DUALSCAN HDS-2000, Omron Healthcare Kyoto, Japan) using the abdominal dual BIA method. 19 , 20 The resultant values were based on the impedance indicated by the difference in electrical conductivity between fat and non-fat tissue. Two paths were used to measure the impedance.…”
