[Risk of prematurity and reported bleeding in pregnancy (author's transl)].
The analysis of 5.139 cases from the prospective study "Pregnancy and Childdevelopment" (supported by the Deutsche Forschungsgemeinschaft) showns that time and frequency of bleeding in pregnancy influence the risk of premature delivery. Every additional bleeding will increase the risk, especially if bleeding occurs in the second trimester. For example the risk of prematurity exceedes 25%, if bleeding occurs four times or more. After bleeding in early pregnancy the frequency of small for gestational age infants is not increased.
