Solar ultraviolet (UV) exposure of people and related health risk is mainly examined by estimating the received UV radiant exposure. However, for several effects such as DNA damage, vitamin D photosynthesis or the probability of developing skin cancer, UV radiant energy is important and with that the size of exposed skin area. There is also a complex interaction between body shape and behavior like sun exposure habits, so that careful analysis is necessary when estimating health effects from UV exposure. In this paper, knowledge on body shape and methods of calculating the total body surface area (BSA) are summarized. BSA depends mainly on the height and weight of a person as well as on gender, ethnicity and body shape. BSA and body shape differ significantly between different populations and both change during life. This paper proposes formulas for BSA that consider height, weight, gender, ethnicity and body shape. As the exposed BSA depends on clothing, finally an approach is presented which aims to calculate the size of body parts released by real garments. In summary, this paper will enable future researchers to quantify the exposed BSA by best matching their study population and consequently investigate risks caused by solar UV exposure.
人们暴露于太阳紫外线（UV）及其相关健康风险主要是通过估算紫外线辐射暴露量来进行研究的。然而，对于诸如DNA损伤、维生素D光合作用或患皮肤癌的概率等多种效应而言，紫外线辐射能量很重要，与之相关的还有暴露皮肤面积的大小。身体形态与行为（如日晒习惯）之间还存在复杂的相互作用，因此在估算紫外线暴露对健康的影响时需要仔细分析。本文总结了有关身体形态以及计算全身表面积（BSA）方法的知识。全身表面积主要取决于一个人的身高、体重以及性别、种族和身体形态。不同人群之间的全身表面积和身体形态差异显著，且两者在一生中都会发生变化。本文提出了考虑身高、体重、性别、种族和身体形态的全身表面积计算公式。由于暴露的全身表面积取决于衣物，最后提出了一种方法，旨在计算实际衣物所覆盖的身体部位面积。总之，本文将使未来的研究人员能够通过最佳匹配其研究人群来量化暴露的全身表面积，从而研究太阳紫外线暴露所造成的风险。
