Utility of multifrequency bioelectrical impedance compared with dual-energy x-ray absorptiometry for assessment of total and regional body composition varies between men and women

The relationship between hepatic steatosis and skeletal muscle mass index in men with type 2 diabetes

“…Third, liver biopsy is a gold standard for quantification of hepatic steatosis, although transient elastography has been validated for diagnosing fatty liver [24]. Fourth, dual-energy X-ray absorptiometry is a gold standard test for evaluating SMM; however, a multifrequency impedance body composition analyzer has good correlation with the dual energy X-ray absorptiometry method and was validated [27,28]. Fifth, although waist circumference rather than BMI may affect CAP as well as SMI, we did not have data of waist circum- ference.…”

“…A multifrequency impedance body composition analyzer has good correlation with the dual energy X-ray absorptiometry method and was also validated [27,28]. We obtained readings for skeletal muscle mass (SMM, kg) and visceral fat area (VFA, cm 2 ).…”

Bioelectrical Impedance and Ultrasound to Assess Body Composition in College-Aged Adults

“…Additionally, the present study used a convenience sample of normal-weight college-age Caucasians making generalizations based on the findings applicable only to young, relatively healthy adults matching the characteristics noted in Table 1. Further investigation is warranted exploring sex-specific agreement of the seven-site US algorithm to BIA as suggested by Anderson et al [8] .…”

“…However, these body composition analysis (BCA) techniques are cost-prohibitive, technically-cumbersome, and/or inaccessible outside of a clinical setting. Rather, common BCA techniques such as skinfolds (SKF) [7] and bioelectric impedance analysis (BIA) [8][9][10] were developed to provide proxy measures of these gold standard techniques. Bioelectrical impedance is a field method that measures the impedance of an electrical current as it travels through the fluid in the body.…”

Plasma B-Type Natriuretic Peptide Levels May Increase Because of Fat Mass Loss by Metformin or Sodium-Glucose Transporter 2 Inhibitors Treatment

“…Segmental body composition was estimated using a patented eight-point tactile electrode system. The device uses six frequencies (1, 5, 50, 250, 500, and 1,000 kHz) and produces 30 impedance values for five body segments: the right and left upper extremities, trunk, and right and left lower extremities [13]. The VFA was also evaluated using this method.…”
