[Significance and incidence of risk factors in pre- and dysmaturity].

Anamnestic and clinical data of 10 654 deliveries were related to premature and dysmature pregnancies. The aim of the study was to get a correlation between special data on the one hand and pre- and dysmaturity on the other hand. The risk of dysmaturity is the highest in gravidae with a gestosisscore of more than 4. The risk of prematurity is the highest in gravidae with bleedings during pregnancy. The most frequent symptom in prematurity was a high cervix-score. It occurred in the prematurity collective in 40.7%. In the dysmaturity collective occurred the abuse of nicotine in 32.9%. Some symptoms have a high prognostic value for a pathological pregnancy, but it was impossible to develop a high risk score following these data. An high specificity was connected with a low sensitivity and vice versa.
