Abstract

Measurement of abdominal adiposity/visceral adipose tissue is clinically relevant in determining individuals’ risks of developing cardiometabolic conditions. Bioelectrical impedance (BIA) can be utilized to estimate visceral adipose tissue as an indicator for cardiometabolic dysregulation. PURPOSE: To determine the correlation between multi-frequency BIA-derived areal visceral fat (cm2) and dual energy x-ray absorptiometry (DXA)-derived volumetric visceral fat (cm3) in normal weight college-aged males. METHODS: Visceral fat was measured three times in the following order: 1) BIA, 2) DXA and 3) BIA in college aged males during the early morning. The mean of the two BIA measurements was used for statistical analyses. All three measures were completed in the same session lasting no longer than 30 minutes. To ensure participants were normally hydrated [urine specific gravity (USG) range: 1.022-1.028], USG was determined immediately prior to the testing session. Correlations between BIA areal visceral fat and DXA volumetric visceral fat and a correlation between BIA visceral fat level and DXA android/gynoid (A/G) percent fat ratio Pearson r correlation coefficients were calculated. RESULTS: Assessments were done on 102 males (mean age = 20.35 ± 1.38 years; mean body mass index = 25.40 ± 3.36 kg·m2). Correlation analysis indicated a moderately high direct correlation between BIA areal visceral fat (47.54 ± 32.78cm2) and DXA volumetric visceral fat (172.20 ± 274.36cm3), r = .678, p < .001. There was a moderately direct correction between BIA visceral fat levels (4.26 ± 3.24) and DXA A/G percent fat ratio (0.83 ± 0.20), r = .570, p < .001. CONCLUSIONS: In normal weight adults, visceral adiposity and A/G percent fat ratio have much stronger associations with cardiometabolic dysregulation than android and gynoid percent fat. The results of this investigation indicate areal visceral fat and visceral fat level derived from BIA may be a set of useful and meaningful indicators of cardiometabolic disease risk when access to DXA is not available. Future research should explore the predictability of BIA-derived areal visceral fat and visceral fat levels, while controlling for factors such as sex, age, and BMI, on cardiometabolic risk.
