本研究的目的是探讨白色和非洲裔美国人（AA）成人的人体测量和肥胖之间的关系的性别和种族差异。内脏脂肪组织（VAT）和皮下脂肪组织（SAT）面积用计算机断层扫描（CT）测量。采用双能X线吸收法（DXA）测量脂肪量（FM）。相关系数被用来评估腰围（WC）和BMI与VAT，SAT和FM的关系。一般线性模型用于比较年龄组（18-39岁和40-64岁）内不同性别和种族的WC或BMI与肥胖之间的关系。样本包括1，667名成年人（男性：489名白色; 120名AA;女性：666名白色，392名AA）。与增值税相比，FM和SAT的WC和BMI相关性最高。无论WC如何，女性的FM水平均高于男性，但FM的性别差异在具有高BMI的年轻AA成人中减弱。对于给定的WC或BMI水平，女性的SAT水平高于男性;然而，显著的相互作用表明，在所有BMI和WC水平之间的关系并不一致。VAT的性别和种族差异随WC和BMI而显著变化。一般来说，白色成年人在较高的BMI和WC水平下，VAT水平高于AA成年人。性别差异，在某些情况下，种族差异，在人体测量和脂肪特异性仓库之间的关系表明，这些特征需要考虑时，从WC或BMI预测肥胖。
The purpose of this study was to examine sex and race differences in the relationship between anthropometric measurements and adiposity in white and African-American (AA) adults. Visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) areas were measured with computed tomography (CT). Fat mass (FM) was measured with dual-energy-X-ray absorptiometry (DXA). Correlation coefficients were used to assess the relationship of waist circumference (WC) and BMI to VAT, SAT, and FM within sex-by-race groups. General linear models were used to compare relationships between WC or BMI, and adiposity across sex and race, within age groups (18–39 and 40–64 years). The sample included 1,667 adults (men: 489 white; 120 AA; women: 666 white, 392 AA). WC and BMI correlations were highest for FM and SAT compared to VAT. Women had higher FM levels than men regardless of WC, but the sex difference in FM was attenuated in younger AA adults with a high BMI. For a given level of WC or BMI, women had higher levels of SAT than men; however, significant interactions indicated that the relationship was not consistent across all levels of BMI and WC. Sex and race differences in VAT varied significantly with WC and BMI. In general, white adults had higher levels of VAT than AA adults at higher levels of BMI and WC. Sex differences, and in some instances race differences, in the relationships between anthropometry and fat-specific depots demonstrate that these characteristics need to be considered when predicting adiposity from WC or BMI.
