In a 5,5% sample of the lifeborns in the GDR in 1974 the distribution of the rate of prematures by uniquebirthes is evaluated for child bearing age, birth-order and age and order at the same time. The sample points a minimum in the group of the 2nd order and age between 25 and 30. Undependently of this result the distribution of the rate of prematures by twins is evaluated for the order of birthes and borns and for child bearing age. The influence of the twins on these distributions is discussed. Modifications of the human reproduction as a result of the decontrol of abortion in 1972 are discussed in its consequences of the rate of prematures. In consequence of the decontrol of abortion an ascent of the rate of prematures would be expected without patronize the risk for premature directly.
在1974年民主德国活产儿的5.5%样本中，按单胎出生情况评估早产率在育龄、胎次以及年龄和胎次同时考量时的分布。该样本显示，在二胎且年龄在25至30岁之间的组别中早产率最低。与这一结果无关，还按生育胎次、出生情况以及育龄评估了双胞胎早产率的分布。讨论了双胞胎对这些分布的影响。探讨了1972年堕胎解禁导致的人类生殖变化对早产率的影响。由于堕胎解禁，预计早产率会上升，而无需直接考虑早产风险。
