[The importance of the risk factor "obesity" during gravidy (author's transl)].

Between 1. 6. 1972 and 31. 12. 1974 obese gravidae with a body weight of 90 kg or more were observed (7,6% of all patients in this period). This 315 patients were compared with a group of 315 patients with normal body weight chosen by random. The results of both groups were compared and evaluated by statistic (t-test, x2-test). A significant higher rate of Diabetes, latent Diabetes, EPH-Gestosis and cases of over-term deliveries were found in the group of obese patients.
