The aim of the present study was to investigate the usefulness of abdominal diameters to indicate visceral fat, their relationship with serum lipids and their capability of detecting changes in visceral fat. Before and after weight loss, visceral and subcutaneous fat, and the sagittal and transverse diameters were assessed by magnetic resonance imaging (MRI) in forty-seven obese men and forty-seven premenopausal obese women with an initial body mass index of 31.0 (SD 2.4) kg/m2. In a subsample (n 21), diameters, were also measured by anthropometry in the standing and supine positions. They were strongly correlated with the diameters derived from the MRI scans. Serum levels of total and HDL-cholesterol and triacylglycerol were measured before weight loss. In women the sagittal diameter correlated less strongly with visceral fat than anthropometrically-assessed waist circumference and waist:hip ratio (WHR). In men these associations were comparable. Changes in visceral fat with weight loss were more strongly correlated with changes in the sagittal diameter and sagittal:transverse diameter ratio (STR) than with changes in waist circumference or WHR in men. In women, changes in the anthropometric variables and the separate diameters (except STR) were not associated with visceral fat loss. In men, but not in women, both the sagittal diameter and the visceral fat area were related to serum lipids. It is concluded that the sagittal diameter and STR may have advantages over waist circumference and WHR in men, particularly in assessing changes in visceral fat, but this could not be demonstrated in women. The ability to predict visceral fat from circumferences and diameters or their ratios is, however, limited in obese men and women.
本研究的目的是探讨腹径用于指示内脏脂肪的效用、其与血脂的关系以及检测内脏脂肪变化的能力。在47名肥胖男性和47名绝经前肥胖女性中，通过磁共振成像（MRI）评估了体重减轻前后的内脏和皮下脂肪以及矢状径和横径，这些受试者的初始体重指数为31.0（标准差2.4）kg/m²。在一个子样本（n = 21）中，还通过人体测量法在站立和仰卧位测量了直径。它们与MRI扫描得出的直径高度相关。在体重减轻前测量了血清总胆固醇、高密度脂蛋白胆固醇和三酰甘油水平。在女性中，矢状径与内脏脂肪的相关性不如通过人体测量评估的腰围和腰臀比（WHR）强。在男性中，这些关联相当。在男性中，体重减轻时内脏脂肪的变化与矢状径和矢状径与横径之比（STR）的变化比与腰围或WHR的变化相关性更强。在女性中，人体测量变量和各直径（STR除外）的变化与内脏脂肪减少无关。在男性而非女性中，矢状径和内脏脂肪面积均与血脂有关。结论是，矢状径和STR在男性中可能比腰围和WHR具有优势，特别是在评估内脏脂肪变化方面，但在女性中未得到证实。然而，在肥胖男性和女性中，通过周长、直径或其比值预测内脏脂肪的能力有限。
