Conventional anthropometric measurements are time consuming and require well trained medical staff. To use three-dimensional whole body laser scanning in daily clinical work, validity, and reliability have to be confirmed.
We compared a whole body laser scanner with conventional anthropometry in a group of 473 children and adolescents from the Leipzig Research Centre for Civilization Diseases (LIFE-Child). Concordance correlation coefficients (CCC) were calculated separately for sex, weight, and age to assess validity. Overall CCC (OCCC) was used to analyze intraobserver reliability.
Body height and the circumferences of waist, hip, upper arm, and calf had an "excellent" (CCC ≥ 0.9); neck and thigh circumference, a "good" (CCC ≥ 0.7); and head circumference, a "low" (CCC < 0.5) degree of concordance over the complete study population. We observed dependencies of validity on sex, weight, and age. Intraobserver reliability of both techniques is "excellent" (OCCC ≥ 0.9).
Scanning is faster, requires less intensive staff training and provides more information. It can be used in an epidemiologic setting with children and adolescents but some measurements should be considered with caution due to reduced agreement with conventional anthropometry.
传统人体测量方法耗时且需要训练有素的医务人员。要在日常临床工作中使用三维全身激光扫描，其有效性和可靠性必须得到确认。
我们在来自莱比锡文明病研究中心（LIFE-Child）的473名儿童和青少年中，将全身激光扫描仪与传统人体测量法进行了比较。分别计算了性别、体重和年龄的一致性相关系数（CCC）以评估有效性。总体CCC（OCCC）用于分析观察者内可靠性。
在整个研究人群中，身高以及腰围、臀围、上臂围和小腿围的一致性为“极佳”（CCC≥0.9）；颈围和大腿围的一致性为“良好”（CCC≥0.7）；头围的一致性为“低”（CCC<0.5）。我们观察到有效性与性别、体重和年龄有关。两种技术的观察者内可靠性均为“极佳”（OCCC≥0.9）。
扫描速度更快，所需的人员培训强度更低，且能提供更多信息。它可用于儿童和青少年的流行病学研究，但由于与传统人体测量法的一致性降低，一些测量结果应谨慎考虑。
