  • Abstract OBJECTIVE We aimed to evaluate a selective screening strategy for gestational diabetes mellitus (GDM) based on the presence of risk factors: BMI =25 kg/m2, age =35 years, family history of diabetes, personal history of GDM, or birth of a child with macrosomia.

    RESEARCH DESIGN AND METHODS Of 20,630 deliveries between 2002 and 2010, we selected 18,775 deliveries in women with no known diabetes and for whom all risk factors were known. GDM was universally screened and defined as fasting plasma glucose level =5.3 mmol/L and/or 2-h postload (75 g) glucose level =7.8 mmol/L.

    RESULTS The prevalence of at least one risk factor has increased since 2002 (P < 0.001) from 51.7 to 61.5%, with no change in the GDM prevalence (mean 14.4%, intention to screen). At least one risk factor was present in 58.5% of women who represented 65.3% of all those with GDM. The presence of risk factors was significantly associated with GDM (odds ratio 1.4 [95% CI 1.3�1.5], P < 0.001) and with GDM-related events (preeclampsia/large for gestational age/dystocia) (P < 0.001) with the following incidences: no GDM/no risk factor 8.8%, no GDM/risk factor 11.1%, GDM/no risk factor 16.7%, and GDM/risk factor 18.2%.

    CONCLUSIONS The presence of risk factors increased during the last decade. This condition is predictive of GDM and GDM-related events. However, a selective screening would lead to missing one-third of the women with GDM who, even without risk factors, had more events than women without GDM. Therefore, these data stand against the present selective screening currently proposed in the French guidelines.
