Utilizing available data and several assumptions, the body content of water, minerals, protein, carbohydrate, and fat has been estimated for a 9-year-old reference boy. This reference boy is leaner than the reference man (13.4 versus 15.3% of body weight) and his fat-free body mass exhibits greater concentration of water (75.5 versus 73.7%) and lesser concentrations of potassium (66.8 versus 68.1 mEq/kg) and total minerals (4.7 versus 6.9%). If age-specific values are used for composition of fat-free body mass body composition), it will be possible to avoid underestimation of fat content calculated from data on total body water and overestimation of fat content calculated from 40K counting data or from body density determined by underwater weighing.
利用现有数据和若干假设，已估算出一名9岁参考男孩体内水、矿物质、蛋白质、碳水化合物和脂肪的含量。该参考男孩比参考男性更瘦（分别占体重的13.4%和15.3%），其去脂体重中水分浓度更高（75.5%对73.7%），钾浓度更低（66.8对68.1毫当量/千克），总矿物质浓度也更低（4.7%对6.9%）。如果将特定年龄值用于去脂体重的成分（身体成分），就有可能避免因总体水数据低估脂肪含量，以及因40K计数数据或水下称重法测定的身体密度高估脂肪含量。
