Body fat (BF) and cardiorespiratory fitness (CRF) are important health markers that ought to be considered in screening exams. The aim of this study was to assess the value of six indicators, i.e., tri-ponderal mass index (TMI), relative fat mass (RFM), waist-BMI ratio, waist-to-height ratio (WHtR), waist-to-hip ratio (WHR) and body mass index (BMI) in predicting CRF in school-aged children. The analysis was based on the data coming from the examination of 190 children participating in school physical education (PE) classes. Their body weight (BW) and height (BH), waist and hip circumference (WC; HC) and percentage of body fat (%BF) were measured; the CRF test was performed with the use of the 20 m shuttle run test (20 mSRT); peak heart rate (HRpeak) was measured; TMI, relative fat mass pediatric (RFMp), waist-BMI ratio, WHtR, BMI and WHR were calculated. Statistical analysis was mainly conducted using regression models. The developed regression models, with respect to the sex and age of the children, revealed RFMp as the strongest CRF indicator ( = 51.1%) and WHR as well as waist-BMI ratio as the weakest ones ( = 39.2% and = 40.5%, respectively). In predicting CRF in school-aged children, RFMp turned out to be comparable to body fat percentage obtained by means of the bioimpedance analysis (BIA) ( = 50.3%), and as such it can be used as a simple screening measure in prophylactic exams of school children. All of these models were statistically significant ( < 0.001).
体脂（BF）和心肺适能（CRF）是筛查检查中应予以考虑的重要健康指标。本研究的目的是评估六项指标，即三相质量指数（TMI）、相对脂肪量（RFM）、腰臀比指数、腰高比（WHtR）、腰臀比（WHR）和体重指数（BMI）在预测学龄儿童CRF方面的价值。该分析基于对190名参加学校体育课（PE）的儿童进行检查所获得的数据。测量了他们的体重（BW）、身高（BH）、腰围和臀围（WC；HC）以及体脂百分比（%BF）；使用20米往返跑测试（20 mSRT）进行CRF测试；测量了峰值心率（HRpeak）；计算了TMI、儿童相对脂肪量（RFMp）、腰臀比指数、WHtR、BMI和WHR。统计分析主要使用回归模型进行。所建立的回归模型，就儿童的性别和年龄而言，显示RFMp是最强的CRF指标（=51.1%），而WHR以及腰臀比指数是最弱的指标（分别为=39.2%和=40.5%）。在预测学龄儿童的CRF时，RFMp与通过生物电阻抗分析（BIA）获得的体脂百分比相当（=50.3%），因此它可以用作学童预防性检查中的一种简单筛查措施。所有这些模型均具有统计学意义（<0.001）。
