The distribution of obstetrical and postnatal risk-factors in a population of 400 newborns was investigated. For documentation, an extended list of Prechtl's list of optimal obstetric conditions was used. The newborns had been selected randomly from two populations, born 1972 in two different hospitals (County hospital, University hospital). The reduction of optimal conditions was calculated by percentiles. It was found that the number -3 (of 52 items, representing full optimal conditions) defined the 10th percentile of the population; number -5 the median, and number -10 the 90th percentile. In addition, percentiles were calculated regarding the history of the mother and the history of the infant respectively. Using the distribution of reduced obstetrical and postnatal optimal conditions allows to compare the history of a single newborn or the histories of a population of newborns with defined problems. Newborns with rather low negative numbers of reduced optimal conditions are at lower risk regarding their psychomotor development wheras newborns with high negative numbers carry a much higher irsk in this respect.
对400名新生儿群体中的产科和产后风险因素分布进行了调查。为了记录，使用了普雷茨尔最佳产科条件列表的扩展清单。这些新生儿是从两个群体中随机选取的，于1972年在两家不同的医院（县医院、大学医院）出生。最佳条件的减少情况通过百分位数计算。结果发现，（代表完全最佳条件的52项中的）-3代表该群体的第10百分位数；-5代表中位数，-10代表第90百分位数。此外，还分别计算了母亲病史和婴儿病史的百分位数。利用减少的产科和产后最佳条件的分布，可以将单个新生儿的病史或有特定问题的新生儿群体的病史进行比较。最佳条件减少负数较低的新生儿在精神运动发育方面风险较低，而负数较高的新生儿在这方面风险要高得多。
