[The problem of premature births in the GDR].

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.
