摘要

目的：本研究旨在通过与臀围、颈围、腰围、腰高比、腰臀比和体重指数等人体测量指标的比较，检验三侧体质量指数（TMI）在青少年肥胖早期筛查中的可靠性。方法：2019年7月至12月，在印度北阿坎德邦鲁德拉普市对1101名12至17岁的在校青少年（男女）进行了一项以学校为基础的横断面研究。使用校准良好的设备收集人体测量数据，并使用印度儿科学会推荐的年龄和性别特定的BMI百分位数临界值来定义超重和肥胖。采用SPSS 16.0软件进行统计分析。进行受试者工作特征曲线分析，利用约登指数（敏感性+特异性- 1）确定人体测量的最佳截断值。结果：1101名研究参与者中，71.5% （n = 787）为男性，28.5% （n = 314）为女性。超重和肥胖患病率分别为10.4%和4.1%。经受试者工作特征曲线分析，TMI青少年的约登指数在超重（0.835）和肥胖（0.869）方面均最高。超重和肥胖男性和女性的最佳TMI临界值分别为>12 kg/m³、>14 kg/m³、>13 kg/m³和>16 kg/m³。TMI在青少年肥胖的早期筛查中表现出优越的预测能力，具有较高的鉴别能力、敏感性和特异性。结论：TMI可作为一种简单、可靠的青少年超重和肥胖早期筛查工具。

Tri-Ponderal Mass Index—A reliable anthropometric index for early screening of adolescent obesity in a school-based setting: A cross-sectional study

Objective

This study was designed to examine the reliability of the Tri-Ponderal Mass Index (TMI) for early screening of adolescent obesity compared with anthropometric measures such as hip circumference, neck circumference, waist circumference, waist-height ratio, waist-hip ratio, and body mass index.

Methods

A school-based, cross-sectional study was conducted between July and December 2019 among 1101 school-going adolescents (both sexes) aged 12 to 17 years, in Rudrapur, Uttarakhand, India. Anthropometric measurements were collected using well-calibrated equipment, and age- and sex-specific BMI percentile cutoff values recommended by the Indian Academy of Pediatrics were used to define overweight and obesity. Statistical analysis was done using SPSS software version 16.0. Receiver operating characteristic curve analysis was conducted, and optimal cutoff values for anthropometric measurements were determined using the Youden Index (sensitivity + specificity – 1).

Results

Of 1101 study participants, 71.5% (n = 787) and 28.5% (n = 314) were males and females, respectively. The prevalences of overweight and obesity were 10.4% and 4.1%, respectively. Receiver operating characteristic curve analysis was conducted and TMI exhibited the highest Youden Index both in terms of overweight (0.835) and obesity (0.869) among adolescents. The optimal TMI cutoff values for overweight and obese males and females were >12 kg/m³ and >14 kg/m³ and >13 kg/m³ and >16 kg/m³, respectively. The TMI demonstrated superior predictive capacity for early screening of adolescent obesity, as indicated by high discriminative power, sensitivity, and specificity.

Conclusions

The TMI can be used as a simple, reliable tool for early screening of overweight and obesity among adolescents.
