[The effect of various parameters on the incidence of premature births].
In a retrospective study among about 17,000 newborns the preterm infants were registered. Newborns delivered in the District Hospital of Schwerin between 1969 and 1977 are included in the above figure. The influence of different parameters on the deliveries of preterm infants was proved. In order to exclude the influence of age and parity on the results of the examinations s standardization of age and parity was done. The frequency of the delivery of preterm infants was dependent on age, parity, occupation and case histories of abortion, interruption of pregnancy and delivery of under-weight.
