Visceral adipose tissue (VAT) has been linked to systemic proinflammatory characteristics, and measuring it accurately usually requires sophisticated instruments. This study aimed to estimate VAT applying a simpler method that uses total subcutaneous fat and total body fat (BF) measurements.
As part of our experimental approach, the subcutaneous fat mass (SFT) was measured via US (SFT), and VAT was quantified by assessing MRI data. Both parameters were added to obtain total body fat (BF). Those results were then compared to values obtained from a bioelectrical impedance analysis (BF). Multiple regression analyses were employed to develop a simplified sex-specific equation for SFT, which was subsequently used in conjunction with BF to determine VAT (VAT).
We observed excellent reliability between BF and BF, with no significant difference in body fat values (20.98 ± 8.36 kg vs. 21.08 ± 8.81 kg, p = 0.798, ICC 0.948). VAT revealed excellent reliability when compared to VAT and no significant difference appeared (women: 0.03 ± 0.66 kg with a 95% CI ranging from -1.26 kg to 1.32 kg, p = 0.815, ICC: 0.955.; men: -0.01 ± 0.85 kg with a 95% CI ranging from -1.69 kg to 1.66 kg, p = 0.925, ICC: 0.952).
Taking an experimental approach, VAT can be determined without MRI.
内脏脂肪组织 (VAT) 与全身促炎特征有关，准确测量通常需要复杂的仪器。本研究旨在应用一种更简单的方法来估计 VAT，该方法使用总皮下脂肪和总体脂 (BF) 测量值。
作为我们实验方法的一部分，通过 US（SFT）测量皮下脂肪质量 (SFT)，并通过评估 MRI 数据来量化 VAT。将这两个参数相加得到总体脂 (BF)。然后将这些结果与生物电阻抗分析 (BF) 获得的值进行比较。采用多元回归分析建立 SFT 的简化性别特异性方程，然后结合 BF 来确定 VAT (VAT)。
我们观察到 BF 和 BF 之间具有极好的可靠性，体脂值没有显著差异（20.98 ± 8.36 kg 与 21.08 ± 8.81 kg，p = 0.798，ICC 0.948）。与 VAT 相比，VAT 具有极好的可靠性，且无明显差异（女性：0.03 ± 0.66 kg，95% CI 范围为-1.26 kg 至 1.32 kg，p = 0.815，ICC：0.955；男性：-0.01 ± 0.85 kg，95% CI 范围为-1.69 kg 至 1.66 kg，p = 0.925，ICC：0.952）。
采用实验方法，无需 MRI 即可确定 VAT。
