In this paper we describe the standardization and reliability of anthropometric measurements carried out by five population survey anthropometrists. For the standardization of anthropometric measurement techniques, one expert anthropometrist conducted two theoretical and practical workshops, in September 2006 and March 2007, where the intra- and interobserver technical errors of measurement (TEMs) were assessed, respectively. For the intraobserver assessment of anthropometric measurements, we studied 121 schoolchildren on two different days. For interobserver assessment, we studied 22 schoolchildren that were measured, during the same period, once by each of the five anthropometrists and by an expert anthropometrist. For skinfold thickness, intraobserver TEMs in general were smaller than 1 mm; for circumferences, TEMs in general were smaller than 1 cm. For the subscapular, suprailiac and calf skinfolds, the intraobserver relative TEMs were greater than the acceptable limit for beginner anthropometrists. Intraobserver reliability for skinfold thickness was greater than 0.95 and for circumferences was greater than 0.99 in almost all cases. The results of interobserver TEMs and reliability were similar to intraobserver assessment. The anthropometrists performed better in the intraobserver relative TEMs because their values were smaller than the acceptable limit. We conclude that the anthropometrists showed a better performance after two assessments of the error of measurement. This suggests that the standardization process of anthropometric measurements was carried out with success.
在本文中，我们描述了由五名人口调查人体测量师进行的人体测量的标准化和可靠性。为了实现人体测量技术的标准化，一名专业人体测量师分别在2006年9月和2007年3月举办了两次理论和实践研讨会，分别评估了测量的观察者内和观察者间技术误差（TEMs）。对于人体测量的观察者内评估，我们在两个不同的日子研究了121名学童。对于观察者间评估，我们研究了22名学童，在同一时期，这五名人体测量师和一名专业人体测量师每人都对他们进行了一次测量。对于皮褶厚度，观察者内TEMs一般小于1毫米；对于周长，TEMs一般小于1厘米。对于肩胛下、髂上和小腿皮褶，观察者内相对TEMs大于新手人体测量师的可接受限度。几乎在所有情况下，皮褶厚度的观察者内可靠性大于0.95，周长的观察者内可靠性大于0.99。观察者间TEMs和可靠性的结果与观察者内评估相似。人体测量师在观察者内相对TEMs方面表现更好，因为他们的值小于可接受限度。我们得出结论，在对测量误差进行两次评估后，人体测量师表现得更好。这表明人体测量的标准化过程取得了成功。
