Objective: The number of heavy newborns is increasing steadily. Often the gestational diabetes (GDM) has not been identified even though an increasing number of pregnant woman are being screened. We examined in a circumscribed area how often the pregnant women passed through an oral glucose tolerance test (oGTT) and had it been realized and interpreted according to the AWMF guidelines.

Methods: In this prospective study we analyzed the OGTT results from 132 pregnant woman overall, separated in 3 groups: Women with detected GDM (n=64), mothers from macrosom newborns but normal OGTT (n=17), control-group (n=47). Finally we included 4 special cases, women with a high risk for GDM but undetected or missing OGTT.

Results: The prevalence for gestational diabetes mellitus was 12.4% during the period of the study. Overall 71/132 women, which means 53.8%, were screened for GDM according to the AWMF guidelines. In due consideration of a 2 week tolerance (= gestational age 24+0 till 27+6 (+/− 1 week)) 70.5% conformed to the guidelines. Reasons for not carrying out an oral glucose tolerance test according to the AWMF guidelines were that the measurement point was too early or too late, the use of capillary measurement, incorrect interpretation of the test values, no initiation of therapy despite pathologic test values, absence of oGTT after pathological GCT. the values were not tested over 2 hours.

Conculsions: By involving a 2 week tolerance the AWMF guidelines are established very satisfactorily but there is room for improvement.
