The authors describe the role of maternal body weight, duration of pregnancy and sex of newborn in the intrauterine growth of the fetus, more exactly in the development of birth weight. In this context they dealt with the validity of the 2500 g upper limit of low-birth-weight-infants in ethnically different populations. From the findings of their studies they draw the conclusion that the weight limit of 2500 g cannot be regarded as valid for all the populations at the statement of the proportion of low-weight births. In the authors view the question of the upper limit of low-weight newborns should be revised. At the statement of the weight limit a differentiation is necessary taking into consideration the constitutional difference in the populations as well as the average birth weight of the newborn and the sex. Authors find it permissible to use the weight value of 2500 g in comparative studies only in case of some populations with identical constitutional characteristics.
作者描述了母亲体重、孕期时长和新生儿性别在胎儿宫内生长，更确切地说是在出生体重发育中的作用。在此背景下，他们探讨了低出生体重儿2500克上限在不同种族人群中的有效性。根据他们的研究结果，他们得出结论，在低体重儿出生比例的表述中，2500克的体重限制不能被视为对所有人群都有效。在作者看来，低体重新生儿上限的问题应该重新审视。在确定体重限制时，有必要进行区分，要考虑到人群的体质差异以及新生儿的平均出生体重和性别。作者认为，只有在某些体质特征相同的人群中，才允许在比较研究中使用2500克的体重值。
