Visceral adipose tissue (VAT) is linked with the metabolic consequences of obesity, being necessary the use alternative methods of predicting this type of fat, like anthropometry. The objective of this study was assess the performance of anthropometry in predicting visceral fat measured with computerized tomography in adults and older adults. Study transversal with 197 individuals underwent computerized tomography (CT) and anthropometry. The variables analized were: visceral adipose tissue area by CT, Sagittal Abdominal Diameter (SAD), Waist Circumference (WC) and Waist-Hip Ratio (WHR). A descriptive analysis, Pearson correlation and ROC curve were carried out. We observed Correlations higher than 0.7 (p = 0.000) between the SAD, WC and the VAT area were found in adult men and older men and in adult women. WHR displayed the least correlations. The most sensitive and specific SAD cut-off points were equal for all the men (Adults: 20.2 cm/Older adults: 20.2 cm) but different for the women (Adults: 21.0 cm; sens.: 83.3; spec.: 79.1/Older adults: 19.9 cm; sens.: 81.0; spec.:79.3). The WC cutoff points that identified a VAT area = 130 cm2 were 90.2 cm and 92.2 cm for men (adult men--sens.: 86.7; spec.: 86.1--and older men-sens.: 79.3; spec.: 77.8 -respectively), while for women the recorded values were 92.3 cm (adult women--sens.: 83.3; spec: 81.4) and 88.2 cm (older women--sens.:76.2; spec.: 69.0). This study showed that WC and SAD achieved the best performance in the identification of visceral fat considered at risk for the development of cardiometabolic diseases in adults and older adults.
内脏脂肪组织（VAT）与肥胖的代谢后果相关，因此有必要使用诸如人体测量学等替代方法来预测此类脂肪。本研究的目的是评估人体测量学在预测成人和老年人通过计算机断层扫描测量的内脏脂肪方面的性能。对197名个体进行了横断面研究，这些个体接受了计算机断层扫描（CT）和人体测量。分析的变量包括：通过CT测量的内脏脂肪组织面积、腹矢状径（SAD）、腰围（WC）和腰臀比（WHR）。进行了描述性分析、Pearson相关性分析和ROC曲线分析。我们观察到，在成年男性、老年男性以及成年女性中，SAD、WC与VAT面积之间的相关性高于0.7（p = 0.000）。WHR的相关性最低。所有男性中，最敏感和特异的SAD切点相同（成年人：20.2厘米/老年人：20.2厘米），但女性不同（成年人：21.0厘米；敏感度：83.3；特异度：79.1/老年人：19.9厘米；敏感度：81.0；特异度：79.3）。识别VAT面积 = 130平方厘米的WC切点，男性为90.2厘米和92.2厘米（成年男性——敏感度：86.7；特异度：86.1——和老年男性——敏感度：79.3；特异度：77.8——分别），而女性的记录值为92.3厘米（成年女性——敏感度：83.3；特异度：81.4）和88.2厘米（老年女性——敏感度：76.2；特异度：69.0）。本研究表明，WC和SAD在识别成人和老年人中被认为有发生心脏代谢疾病风险的内脏脂肪方面表现最佳。
