目的：为了评估身体质量指数（BMI），%体脂，腰围和腰臀比作为腹部内脏脂肪（AVF）level.Design的预测指标的价值：从458名女性和331名男性法裔加拿大人后裔的年龄范围从18-72岁的横断面测量。AVF水平通过计算机断层扫描评估，BMI计算为体重（kg）除以身高（2）（m），身体密度通过水下称重得出，%体脂通过Siri方程估计身体密度计算。腰臀比计算为腰围除以臀围。受试者工作特征曲线（ROC）用于确定最佳截止点。
OBJECTIVE: To evaluate the merit of body mass index (BMI), % body fat, waist circumference and waist-to-hip ratio as predictors of abdominal visceral fat (AVF) level.DESIGN: Cross-sectional measurements obtained from 458 female and 331 male subjects of French Canadian descent with an age range from 18-72 y.MEASUREMENTS: AVF level was assessed by computed tomography, BMI was calculated as weight (in kg) divided by stature(2) (in m), body density was derived from underwater weighing and % body fat was computed from the estimate of body density with the Siri equation. Waist-to-hip ratio was calculated as waist circumference divided by hip circumference. Receiver operating characteristic (ROC) curves were used to identify the optimal cut-off points.RESULTS: In younger women (
