已公布的人类胎儿化学分析数据已被用来构建具有代表性身体成分的参考胎儿。对于24到40周的胎龄，提供了参考胎儿的身体成分，包括水、脂肪、蛋白质和主要矿物质。单位体重的水、钠和氯的浓度随着胎龄的增加而降低，而蛋白质、脂肪、钙、磷、镁和钾的浓度则增加。根据各年龄段的身体成分估计和体重的增加，计算出增重的组成和身体各部分的每日增量。
Published data from chemical analyses of human fetuses have been utilized to construct a reference fetus of representative body composition. For gestational ages 24 through 40 weeks, body composition of the reference fetus is presented, including water, lipid, protein and major minerals. Concentrations of water, sodium, and chloride per unit of body weight decrease with increasing gestational age, whereas those of protein, lipid, calcium, phosphorus, magnesium and potassium increase. From the estimates of body composition at each age and from the gain in body weight, composition of gain and daily increments of body components have been calculated.
