177人行腹部 CT 扫描的体检者(男性87人,女性90人)进行腹高、腰围、体重指数和腰围身高比值的测量。比较腹高等体表测量指标与内脏脂肪的相关性。分性别应用受试者特征工作(ROC)曲线,以腰椎4~5层面冠状位的内脏脂肪面积≥80 cm2为切点,约登指数确定各指标在腹型肥胖的切点值。男性腹型肥胖的比例为80.5%,女性为65.6%；校正了年龄因素,与其他的体表测量指标相比,腹高与内脏脂肪有高度相关性,Pearson 相关系数分别为0.825和0.732,预测腹型肥胖的切点在男性和女性分别为20 cm 和20.3 cm,曲线下面积分别是0.914和0.892。腹高和腰围身高比值在预测腹型肥胖上优于腰围和体重指数。腰围、体重指数和腰围身高比值的最佳切点是：男性91 cm、25 kg/ m2和0.52；女性86.5 cm、25 kg/ m2和0.54。腹高能够有效预测腹型肥胖,20 cm 可作为腹型肥胖的切点。

Totally 177 individuals (87 males and 90 females), who took abdominal computer tomography were enrolled. Anthropometric surrogates such as abdominal height( AH), waist circumference( WC), body mass index(BMI), and waist to height ratio(WHtR) were measured. Correlations between AH, WC, BMI, and WHtR with visceral abdominal fat were analyzed, and receiver operating characteristic curves ( ROC) were prepared for detecting abdominal adiposity at or beyond 80cm2 using lumbar vertebra 4-5 cross-section visceral fat areas as the screening cut-point within gender separately. Youden′s index was used to determine cut-off values of AH, WC, BMI, and WHtR by which to classify excess abdominal fat. 70(80. 5% ) males and 59(65. 9% ) females had abdominal obesity. Compared to other anthropometic indicators, AH presented the highest correlation with visceral adipose fat. The pearson correlation efficiencies were 0. 825 and 0. 732, the cut-off points were 20 cm and 20. 3 cm in male and female respectively. After controlling for age, receiver operating characteristic analysis showed that AH, followed by WHtR, outperformed WC and BMI in identifying central obesity participants. Optimal cut-off values of the physical anthropometric indices to indentify abdominal adiposity were 20 cm(AH), and 91 cm(WC) 25 kg/ m2 (BMI), and 0. 52(WHtR) for men, and 20. 3 cm(AH), 86. 5 cm(WC), 25 kg/ m2(BMI), and 0. 54(WHtR) for women. AH is effective for predicting visceral adiposity and might be considered the best predictor of abdominal obesity at a cut-point of 20cm in Chinese adults.
