A new anthropometric rate called energy/protein ratio (E/P) which results from the division of the logarithmic transformation of tricipital skin fold (F) by the logarithm of branchial muscle circumference (BMC) is described. In a study of a sample of healthy preschool children from 97 day-care centers of the Havana City it was proved a relationship between adiposity and the muscular mass of the arm middle third which depends on age, sex and race and is normally distributed. Percentiles for each age and sex were obtained and it was confirmed the dependence of age and differences in each sex. It was also proved the quality of E/P in assessing variations of the muscular mass as well as a relationship between energy and protein storages. The E/P ratio is a new contribution to nutritional evaluation since it offers a new approach for the use of arm measurements, specially the tricipital fold, and demonstrates the easiness for its obtention and its reliability. The ratio may be applied either to individual assessment or to field studies. Measurements may be performed by well trained personnel, which may record the primary data and screen initially according to the percentile distribution of the values obtained. The E/P ratio may be obtained by a computerized program or a nomogram designed to that purpose.
描述了一种新的人体测量比率，即能量/蛋白质比率（E/P），它是通过将三头肌皮褶厚度（F）的对数变换除以肱肌周长（BMC）的对数得到的。在一项对哈瓦那市97个日托中心的健康学龄前儿童样本的研究中，证实了肥胖与手臂中三分之一肌肉量之间的关系，这种关系取决于年龄、性别和种族，且呈正态分布。获得了各年龄和性别的百分位数，并证实了年龄依赖性以及各性别之间的差异。还证明了E/P在评估肌肉量变化方面的质量以及能量和蛋白质储存之间的关系。E/P比率是营养评估的一项新贡献，因为它为使用手臂测量值，特别是三头肌皮褶厚度，提供了一种新方法，并展示了其获取的简便性和可靠性。该比率可应用于个体评估或现场研究。测量可由训练有素的人员进行，他们可以记录原始数据并根据所获得值的百分位数分布进行初步筛选。E/P比率可通过为此目的设计的计算机程序或列线图获得。
