Background:
To evaluate the impact of the new IADPSG thresholds on gestational diabetes mellitus (GDM) prevalence.
Methods:
Universal screening for GDM was performed in 200 consecutive patients at 24 to 28 weeks with 75 g oral glucose tolerance test.
Results:
The prevalence of GDM was 14.0%. We observed that among the 28 patients with GDM, 16 (57.1%) had only one abnormal value, 10 (35.7%) two abnormal values and only two (7.2%) had three abnormal values. For the 16 patients with one abnormal value, 13 of them (81.2%) have an abnormal fasting plasma glucose (FPG). Patients with GDM had an increased body mass index (29.6 kg/m(2) vs 25.1 kg/m(2), P<0.001) and more important rates of familial history of type II diabetes (46.4% vs 21.5%, P<0.005) and history of GDM in a previous pregnancy (21.4% vs 2.9%, P<0.002) compared to non-GDM patients. Birth weight was increased in offspring of mothers with GDM (3451.3g vs 3387.4 g, P<0.05).
Conclusion:
Our study found an increased rate of GDM with the new IADPSG criteria compared to previous published data. Higher rates of GDM represent a challenge for the organization of perinatal teams involved in GDM care.
