Objective Body mass index (BMI) and tri-ponderal mass index (TMI) are anthropometric measures to evaluate body adiposity in the various age groups. The present study aims to compare the predictive value of TMI and BMI for metabolic syndrome (Mets) in children and adolescents of both genders. Subjects and methods A cross-sectional study conducted on 3731 Iranian children and adolescents aged 7-18 years obtained from the fifth survey of 'Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease' (CASPIAN-V) study. The predictive value of BMI and TMI for MetS were determined using Receiver-operator curves. Logistic regression analysis was used to assess the relationship between these indices with MetS. Results 52.6% of participants were boys. The mean (standard deviations) age for boys and girls were 12.62 (3.02) and 12.25 (3.05) years, respectively. In boys, the area under the curve (AUC) of TMI was greater than BMI for all age groups. AUC of TMI was also greater than BMI for age group of 11-14 years (AUC = 0.74; 95% CI (0.67, 0.81)) in girls. Furthermore, our findings showed that odds ratio of Mets for TMI was greater than BMI in age groups of 11-14 years (OR = 1.33 vs 1.22) and 15-18 years (1.16 vs 1.15) in girls and boys, respectively. Conclusion TMI and BMI had moderate predictive value for identifying MetS. However, TMI was a better predictor of MetS than BMI in both genders, especially in age groups of 11-14 and 15-19 years for girls and boys.
目的 体重指数（BMI）和三头肌皮褶厚度指数（TMI）是评估不同年龄组身体肥胖程度的人体测量指标。本研究旨在比较TMI和BMI对儿童和青少年代谢综合征（Mets）的预测价值。
对象与方法 一项横断面研究，对从“儿童和青少年成人非传染性疾病监测与预防”（CASPIAN-V）研究的第五次调查中选取的3731名7-18岁的伊朗儿童和青少年进行。使用受试者工作特征曲线确定BMI和TMI对Mets的预测价值。采用逻辑回归分析评估这些指标与Mets之间的关系。
结果 52.6%的参与者为男孩。男孩和女孩的平均（标准差）年龄分别为12.62（3.02）岁和12.25（3.05）岁。在男孩中，所有年龄组TMI的曲线下面积（AUC）均大于BMI。在女孩中，11-14岁年龄组TMI的AUC也大于BMI（AUC = 0.74；95%置信区间（0.67，0.81））。此外，我们的研究结果表明，在女孩和男孩中，11-14岁年龄组（OR = 1.33对1.22）和15-18岁年龄组（1.16对1.15）中，Mets的TMI比值比大于BMI。
结论 TMI和BMI在识别Mets方面具有中等预测价值。然而，在男女两性中，TMI是比BMI更好的Mets预测指标，尤其是在女孩和男孩的11-14岁和15-19岁年龄组。
