In order to evaluate the reliability of anthropometry in assessing protein stores we have compared, in 10 normal adults and 82 surgical patients with varying degrees of weight loss, measurements of weight/height, arm circumference, arm muscle circumference, and arm muscle area with direct measurements of body nitrogen using in vivo neutron activation analysis. Anthropometry is reliable for the assessment of protein nutrition in groups of patients (for 100 patients 95% confidence limits are +/- 30 g nitrogen) but the magnitude of variance shown makes it inappropriate for assessing the individual as a single measurement (95% confidence limits are +/- 300 g nitrogen). Repeat measurements were made after 2 weeks on 35 patients and there was no correlation between changes in body nitrogen and changes in the anthropometric measurements. Anthropometry is not reliable in following changes in body nitrogen in individual patients over short periods of time.
为了评估人体测量学在评估蛋白质储备方面的可靠性，我们对10名正常成年人和82名不同程度体重减轻的外科患者进行了比较，将体重/身高、上臂围、上臂肌肉围和上臂肌肉面积的测量值与使用体内中子活化分析直接测量的身体氮含量进行了对比。人体测量学对于评估患者群体的蛋白质营养状况是可靠的（对于100名患者，95%置信区间为±30克氮），但所显示的方差大小使其不适用于将个体作为单一测量对象进行评估（95%置信区间为±300克氮）。对35名患者在2周后进行了重复测量，身体氮含量的变化与人体测量学测量值的变化之间没有相关性。人体测量学在短期内跟踪个体患者身体氮含量的变化方面不可靠。
