From an allometric analysis of single and multiple human pregnancies the metabolic rate and the degree of encephalization of neonates could be calculated. As a result of the reduction in somatic growth in multiple gestations the oxygen consumption per neonate was found to be an inverse non-linear function of litter size. Furthermore, differential growth rates between brain weight, body weight, and body length, respectively, in the late prenatal period revealed that twins at birth are in general less encephalized than are newborns from single births.
通过对单胎和多胎人类妊娠的异速生长分析，可以计算出新生儿的代谢率和脑化程度。由于多胎妊娠中躯体生长的减少，发现每个新生儿的耗氧量是胎仔数的反非线性函数。此外，产前后期脑重量、体重和体长之间的差异生长率表明，双胞胎出生时的脑化程度通常低于单胎新生儿。
