In order to assess birth risk a study was made of parturition and neonatal findings in 196 late primiparae from a total collective of 4993 primiparae and multiparae covering all age groups. The investigation covered the frequency of surgery, the type of delivery, indications for surgery, Apgar scores, the birthweight of the newborns, the incidence of premature and deficient births, neonatal morbidity and mortality, and maternal mortality. With advancing age of the mother there is a distinct increase in the number of surgical deliveries, while the number of normal-weight infants decreases. There is a slight increase in the number of infants weighing less than 2500 g, and a distinct increase in the number weighing over 4000 g. The reason for this is not the number of diabetic or prediabetic mothers, but the high proportion of boys. Neither age nor parity have any significant influence on the incidence of premature and deficient births. With regard to neonatal morbidity and mortality, late primiparae do not differ fundamentally from the patient collective as a whole. The incidence of surgical delivery is distinctly higher among late primiparae, but this enables them to give birth with a risk which is only slightly higher than that for younger women.
为了评估分娩风险，对4993例初产妇和经产妇（涵盖所有年龄组）中的196例晚期初产妇的分娩及新生儿情况进行了研究。调查内容包括手术频率、分娩类型、手术指征、阿氏评分、新生儿出生体重、早产和低体重儿的发生率、新生儿发病率和死亡率以及孕产妇死亡率。随着母亲年龄的增长，手术分娩的数量明显增加，而正常体重婴儿的数量减少。体重不足2500克的婴儿数量略有增加，体重超过4000克的婴儿数量明显增加。原因并非糖尿病或糖尿病前期母亲的数量，而是男孩的比例较高。年龄和胎次对早产和低体重儿的发生率均无显著影响。关于新生儿发病率和死亡率，晚期初产妇与整个患者群体并无根本差异。晚期初产妇的手术分娩发生率明显更高，但这使得她们分娩时的风险仅略高于年轻女性。
