The reliability of anthropometric measurements of term infants has not been studied sufficiently to determine if these measurements are reliable enough to be used in clinical practice and research. This study described the intra- and interexaminer reliability of the following anthropometric measurements: weight (WT), head circumference (HC), chest circumference (CC), abdominal circumference (AC), mid-arm circumference (MAC), and length.
A convenience sample of 50 clinically stable term infants was studied. Two examiners obtained the six measurements twice using blank tape measures. The order of examiners was randomized and the examiners were masked to their own and the other examiners' measurements.
The intraexaminer mean absolute differences were as follows: WT = 1.88, 3.28 g; HC = 0.29, 0.29 cm; CC = 0.50, 0.78 cm; AC = 0.71, 0.77 cm; MAC = 0.36, 0.39 cm; length = 0.92, 1.18 cm. The interexaminer mean absolute differences were as follows: WT = 1.94, 1.66 g; HC = 0.37, 0.36 cm; CC = 0.59, 0.72 cm; AC = 0.99, 0.77 cm; MAC = 0.41, 0.57 cm; length = 1.57, 1.47 cm.
These findings indicate that intraexaminer differences tended to be smaller than interexaminer differences for all measures except weight, which remained stable for intra- and interexaminer comparisons. These findings also suggest that weight and head circumference were the most reliable measures, whereas length and mid-arm circumference were the least reliable measures.
足月儿人体测量的可靠性尚未得到充分研究，以确定这些测量是否足够可靠，可用于临床实践和研究。本研究描述了以下人体测量的检查者内和检查者间的可靠性：体重（WT）、头围（HC）、胸围（CC）、腹围（AC）、上臂围（MAC）和身长。
对50例临床稳定的足月儿进行便利抽样研究。两名检查者使用空白卷尺对这六项测量进行了两次测量。检查者的顺序是随机的，检查者对自己和其他检查者的测量结果均不知情。
检查者内平均绝对差异如下：WT = 1.88、3.28克；HC = 0.29、0.29厘米；CC = 0.50、0.78厘米；AC = 0.71、0.77厘米；MAC = 0.36、0.39厘米；身长 = 0.92、1.18厘米。检查者间平均绝对差异如下：WT = 1.94、1.66克；HC = 0.37、0.36厘米；CC = 0.59、0.72厘米；AC = 0.99、0.77厘米；MAC = 0.41、0.57厘米；身长 = 1.57、1.47厘米。
这些发现表明，除体重外，所有测量的检查者内差异往往小于检查者间差异，体重在检查者内和检查者间比较中保持稳定。这些发现还表明，体重和头围是最可靠的测量指标，而身长和上臂围是最不可靠的测量指标。
