We analysed the influence of the mother's age on the weight of the newborn of a total of 7.715 newborn infants (3.922 boys and 3.793 girls). Under consideration of further age-depending factors (parity, weight of the mother) we could not find any statistically significant influence of the mother's age on the birth weight of her child. On the basis of data of 7.263 births we investigated the correlation between duration of pregnancy and the mother's age. The result was that contrary to what can be found in the literature the bearing periods over the whole of the mothers' age were constant, and thus no increased rate of prematures in juvenile pregnant women could be ascertained.
我们分析了母亲年龄对总共7715名新生儿（3922名男孩和3793名女孩）体重的影响。在考虑了其他与年龄相关的因素（胎次、母亲体重）后，我们未发现母亲年龄对其孩子出生体重有任何统计学上的显著影响。基于7263例分娩的数据，我们研究了孕期时长与母亲年龄之间的相关性。结果是，与文献中所发现的情况相反，在母亲的整个年龄范围内，生育期是恒定的，因此未发现年轻孕妇早产率增加。
