Total body potassium was measured in 103 healthy adults using a shadow-shield whole-body monitor of high sensitivity. The range of height was 147 to 192 cm, of weight 43 to 92 kg, and of age 18 to 77 years. The values obtained for total body potassium were correlated with height, with weight, and with height and weight. Age was then included as an additional variable. The standard deviation from regression was smaller when total body potassium was correlated with height than with weight and was further reduced, to about 9%, in a multiple regression using height and age. The advantages of this relationship over indices involving weight are discussed. The smallest standard deviation from regression, 7.5%, was obtained when total body potassium was correlated with height, weight, and age. The usefulness of this relationship is discussed with comment on its limitations.A regression equation was derived between lean body mass (derived from height and weight) and total body potassium with a standard deviation from regression of 5.5% in males and 7.3% in females.
使用高灵敏度的阴影屏蔽全身监测仪对103名健康成年人进行了全身钾含量测量。身高范围为147至192厘米，体重范围为43至92千克，年龄范围为18至77岁。所获得的全身钾含量值与身高、体重以及身高和体重相关。随后将年龄作为一个额外变量纳入。当全身钾含量与身高相关时，回归标准差比与体重相关时更小，并且在使用身高和年龄的多元回归中进一步降低至约9%。讨论了这种关系相对于涉及体重的指标的优势。当全身钾含量与身高、体重和年龄相关时，获得了最小的回归标准差，为7.5%。讨论了这种关系的实用性，并对其局限性进行了评论。推导了瘦体重（由身高和体重得出）与全身钾含量之间的回归方程，男性的回归标准差为5.5%，女性为7.3%。
