Abstract

OBJECTIVE

To describe the standardization process and reliability of anthropometric and bioelectrical impedance analysis (BIA) measurements. We examined both intra- and interobserver errors for skinfolds, circumferences and BIA.

METHODS

For the intraobserver error assessment, first of all, 202 adolescents in the pilot study (110 boys, 92 girls, aged 13.64+/-0.78 years) were assessed. For the second intraobserver and interobserver assessments, 10 adolescents were studied (5 boys and 5 girls).

RESULTS

The pilot study's intraobserver technical errors of measurement (TEMs) were between 0.12 and 2.9 mm for skinfold thicknesses, and between 0.13 and 1.75 cm for circumferences. Intraobserver reliability for skinfold thicknesses was greater than 69.44% and beyond 78.43% for circumferences. The final workshop's intraobserver TEMs for skinfold thicknesses and circumferences were smaller than 1; for BIA resistance TEMs were smaller than 0.1 Omega and for reactance they were smaller than 0.2 Omega. Intraobserver reliability values were greater than 95, 97, 99 and 97% for skinfold thicknesses, circumferences, BIA resistance and reactance, respectively. Interobserver TEMs for skinfold thicknesses and circumferences ranged from 1 to 2 mm; for BIA they were 1.16 and 1.26 Omega for resistance and reactance, respectively. Interobserver reliability for skinfold thicknesses and circumferences were greater than 90%, and for BIA resistance and reactance they were greater than 90%.

CONCLUSIONS

After the results of the pilot study, it was necessary to optimize the quality of the anthropometric measurements before the final survey. Significant improvements were observed in the intraobserver reliabilities for all measurements, with interobserver reliabilities being higher than 90% for most of the measurements.The Healthy Lifestyle in Europe by Nutrition in Adolescence Study aims to describe total body fat percentage and anthropometric indices of body fat distribution in European adolescents.

摘要

目的

描述人体测量和生物电阻抗分析（BIA）测量的标准化过程及可靠性。我们检查了皮褶厚度、周长测量以及BIA测量中的观察者内和观察者间误差。

方法

对于观察者内误差评估，首先，对初步研究中的202名青少年（110名男孩，92名女孩，年龄13.64±0.78岁）进行评估。对于第二次观察者内和观察者间评估，研究了10名青少年（5名男孩和5名女孩）。

结果

初步研究中，皮褶厚度的观察者内测量技术误差（TEMs）在0.12至2.9毫米之间，周长的观察者内测量技术误差在0.13至1.75厘米之间。皮褶厚度的观察者内可靠性大于69.44%，周长的观察者内可靠性超过78.43%。最终研讨会中，皮褶厚度和周长的观察者内TEMs小于1；BIA电阻的TEMs小于0.1Ω，电抗的TEMs小于0.2Ω。皮褶厚度、周长、BIA电阻和电抗的观察者内可靠性值分别大于95%、97%、99%和97%。皮褶厚度和周长的观察者间TEMs在1至2毫米之间；BIA电阻和电抗的观察者间TEMs分别为1.16和1.26Ω。皮褶厚度和周长的观察者间可靠性大于90%，BIA电阻和电抗的观察者间可靠性大于90%。
