OBJECTIVE: To evaluate the effect of the change in the gestational @entity6 (GDM) screening policy from risk-factor based to comprehensive screening on the prevalence and type of GDM and characteristics of GDM pregnancies. DESIGN: Population-based register study in Finland. Subjects were GDM @entity1 who gave birth before (2006, n=5185) and after (2010, n=6683) the policy change. All the other @entity1 in those years without @entity6 as controls (51759 and 52398 respectively). METHODS: GDM @entity1 with singleton pregnancy were identified through The Finnish Medical Birth Register by abnormal oral @entity413 tolerance test or initiation of @entity2690 . Main outcome measures were prevalence of GDM (total and @entity2690 /diet-treated), and caesarean section rate. RESULTS: The proportion of screened mothers increased from 27.5 to 51.3% and the total prevalence of GDM from 9.1 to 11.3%. This increase consisted mainly of diet-treated mothers, while the number and proportion of @entity2690 -treated mothers decreased (21.8% vs13.3%, P<0.001). The proportion of primiparous @entity1 increased (34.5-39.4%, P<0.0001) and mean pre-pregnancy BMI decreased (28.6-28.2, P<0.001). The overall caesarean section rate remained the same but increased among @entity1 with GDM (20.8-22.1%) adjusted odds ratios being 1.22 (95% CI 1.14, 1.31) during comprehensive and 1.10 (95% CI 1.02, 1.19) during risk factor-based screening. CONCLUSIONS: The shift to comprehensive screening led to a significant increase in @entity1 with GDM, who were more often primiparous and had a lower BMI. Comprehensive screening did not perform better in diagnosing @entity1 needing @entity2690 treatment.
