Asian women are known to have a larger amount of abdominal fat (AF) for the same level of BMI compared with Caucasian and African-American women. This study was aimed to determine whether waist circumference (WC) could be useful as an index of AF compared with AF measured by dual energy x-ray absorptiometry (DXA) before and after a weight-loss program in Asian women. Thirty-eight healthy, pre-menopausal obese Korean women (body fat percent>30%) were enrolled and followed during a 6-week weight-loss program including herbal formula, calorie restriction, and exercise. Anthropometry and DXA measurements were performed before and after weight-loss. A specific region of interest (ROI, L2-iliac crest) by DXA was correlated with anthropometry at baseline: WC (gamma=0.91)>BMI (gamma=0.87)>Waist-Height ratio (WHtR, gamma=0.82)>WHR (gamma=0.46); and after weight loss: BMI (gamma=0.88)>WC (gamma=0.84)>WHtR (gamma=0.82), all p<0.01. The change in DXA ROI showed a reasonable correlation with change in anthropometry: BMI (gamma=0.63, p<0.01)>WC (gamma=0.39, p<0.05)>WHtR (gamma=0.37, p<0.05). A stepwise multiple regression analysis revealed that 83% of the variance in DXA derived AF was explained by WC at baseline, WC and BMI at follow-up, respectively. This study suggests that WC could be a good predictor of AF for Korean pre-menopausal women.
众所周知，与白种人和非裔美国女性相比，亚洲女性在相同BMI水平下腹部脂肪（AF）含量更高。本研究旨在确定在亚洲女性减肥计划前后，与通过双能X线吸收法（DXA）测量的AF相比，腰围（WC）是否可作为AF的指标。38名健康的绝经前肥胖韩国女性（体脂百分比>30%）参与了一项为期6周的减肥计划，该计划包括草药配方、热量限制和运动，并在计划期间接受随访。在减肥前后进行人体测量和DXA测量。DXA测量的特定感兴趣区域（ROI，L2-髂嵴）与基线时的人体测量指标相关：WC（γ=0.91）>BMI（γ=0.87）>腰高比（WHtR，γ=0.82）>腰臀比（WHR，γ=0.46）；减肥后：BMI（γ=0.88）>WC（γ=0.84）>WHtR（γ=0.82），所有p<0.01。DXA ROI的变化与人体测量指标的变化显示出合理的相关性：BMI（γ=0.63，p<0.01）>WC（γ=0.39，p<0.05）>WHtR（γ=0.37，p<0.05）。逐步多元回归分析显示，DXA得出的AF中83%的方差分别由基线时的WC、随访时的WC和BMI解释。本研究表明，WC可能是韩国绝经前女性AF的良好预测指标。
