[Influence of age on risk-factors during pregnancy, delivery and puerperium of primiparae (author's transl)].

The course of pregnancy and delivery of 600 primiparae is being reported. These were divided into four age groups: very young primiparae (14-16 years of age, Group I), older primiparae (35-39 years of age, Group III) and old primiparae (40 years and more, Group IV). These age groups are being compared to a collective of primiparae, by whom the delivery took place at an age between 17 and 34 years (Group II). In these age groups the difference in complication rate during pregnancy, delivery and puerperium is demonstrated. The differences were statistically secured by means of X-2-test. The very young primipara shows the least tendency to delivery complications, still her pregnancy should be considered more risky as compared to Group II, owing to the higher rate of gestosis and the tendency to premature delivery. Groups III and IV show a rising risk rate with increasing age in regard to gestosis (10, 8-30, 8%) and premature delivery (15, 4-28, 6%); also the higher rate of operational delivery was significant (38, 9-44, 6%). The highest risk rate is to be expected in women, who deliver the first time at an age above 40 years. Also the perinatal mortality of newborn is at its highest in this group.
