[Diabetes screening in pregnant patients with different risk factors. Benefits, therapeutic success, consequences].

600 ethnically heterogeneous patients with various risk factors from outpatient obstetric clinic of the UFK Ulm were screened for gestational diabetes. Incidence with the 100 g oGTT was 21%, with fasting levels having the lowest prognostic value, and one hour levels having the best. After the diagnosis of gestational diabetes was established patients were counselled and put on diet, 7% received insulin additionally. Weight gain was far more acceptable in those patients compared to the group of patients with normal metabolism. We observed no significant differences concerning fetal macrosomia, caesarean section-rates, newborn apgar and ph-values compared to normal pregnant women. We confirmed the known risk factors, personal history, familial disposition and maternal age. A screening based only on these criteria, however, would fail to detect 20% of patients with gestational diabetes. A general screening must be postulated.
