Body surface area is a physiological quantity relevant for many medical applications. In clinical practice, it is determined by empirical formulae. 3D laser-based anthropometry provides an easy and effective way to measure body surface area but is not ubiquitously available. We used data from laser-based anthropometry from a population-based study to assess validity of published and commonly used empirical formulae.
We performed a large population-based study on adults collecting classical anthropometric measurements and 3D body surface assessments (N = 1435). We determined reliability of the 3D body surface assessment and validity of 18 different empirical formulae proposed in the literature. The performance of these formulae is studied in subsets of sex and BMI. Finally, improvements of parameter settings of formulae and adjustments for sex and BMI were considered.
3D body surface measurements show excellent intra- and inter-rater reliability of 0.998 (overall concordance correlation coefficient, OCCC was used as measure of agreement). Empirical formulae of Fujimoto and Watanabe, Shuter and Aslani and Sendroy and Cecchini performed best with excellent concordance with OCCC > 0.949 even in subgroups of sex and BMI. Re-parametrization of formulae and adjustment for sex and BMI slightly improved results.
In adults, 3D laser-based body surface assessment is a reliable alternative to estimation by empirical formulae. However, there are empirical formulae showing excellent results even in subgroups of sex and BMI with only little room for improvement.
体表面积是一个与许多医学应用相关的生理量。在临床实践中，它是通过经验公式来确定的。基于三维激光的人体测量法提供了一种简单有效的测量体表面积的方法，但并非普遍可用。我们使用了一项基于人群的研究中基于激光的人体测量数据，以评估已发表的常用经验公式的有效性。
我们对成年人进行了一项大规模的基于人群的研究，收集经典人体测量数据和三维体表评估数据（N = 1435）。我们确定了三维体表评估的可靠性以及文献中提出的18种不同经验公式的有效性。在性别和体重指数亚组中研究了这些公式的性能。最后，考虑了公式参数设置的改进以及性别和体重指数的调整。
三维体表测量显示出评估者内部和评估者之间的可靠性极佳，一致性相关系数为0.998（总体一致性相关系数，OCCC用作一致性度量）。藤本和渡边、舒特和阿斯兰尼以及森德罗伊和切奇尼的经验公式表现最佳，即使在性别和体重指数亚组中，与OCCC的一致性也极佳，OCCC > 0.949。公式的重新参数化以及性别和体重指数的调整略微改善了结果。
在成年人中，基于三维激光的体表评估是一种可靠的替代经验公式估算的方法。然而，有一些经验公式即使在性别和体重指数亚组中也显示出优异的结果，改进空间很小。
