Abstract

OBJECTIVE

To evaluate the use of ultrasonography (US) as an alternative to dual-energy x-ray absorptiometry (DXA) to predict the percentage ratio of android/gynoid (A/G) fat mass.

METHODS

This was a cross-sectional study. Twenty-eight participants included in the study underwent whole-body DXA examinations and the A/G ratio was calculated. Soft-tissue US was performed in several standardised anthropometric areas of the body. Correlation analysis between abdominal and gluteal-femoral fat thickness based on US and A/G ratio was conducted using the Pearson or Spearman test depending on the data normality. Multiple regression analysis using the backward stepwise method was performed to establish an equation for estimating the A/G ratio.

RESULTS

There was a strong and significant correlation between fat thickness in the six anthropometric areas and the A/G ratio in female participants. The analysis revealed three anthropometric areas: upper abdomen (S4), lower abdomen (S5), and mid-xiphoid-umbilical region (S7), that can accurately predict the A/G ratio by 82.3%. (P < 0.05). However, no such correlation was found in male participants.

CONCLUSIONS

US measurement of fat thickness can predict A/G ratio in the female population. However, this method is not recommended for men.

摘要

目的

评估超声（US）作为双能 X 射线吸收法（DXA）的替代方法，用于预测安卓/臀（A/G）脂肪量的百分比比值。

方法

这是一项横断面研究。28 名参与者接受了全身 DXA 检查，并计算了 A/G 比值。在身体的几个标准人体测量区域进行了软组织 US 检查。根据数据正态性，使用 Pearson 或 Spearman 检验对基于 US 的腹部和臀股脂肪厚度与 A/G 比值之间的相关性进行了分析。使用逐步后退法进行多元回归分析，以建立估计 A/G 比值的方程。
