Of 1,263 women who were diagnosed with GDM from
2005 to 2009, 1157 were diagnosed with IGT and 106 with
diabetes based on their OGTT glucose concentrations at 26–
30 gestational weeks. After a mean 2.26-year (27.2 months)
delivery of 1263 GDM mothers, 83 were diagnosed with type
2 diabetes (6.6%) and 400 with prediabetes (31.7%). GDM
women with diagnosed diabetes during pregnancy or after
delivery were slightly older, their prepregnancy and current
BMI and fasting and 2-hour glucose in the OGTT at 26–30
gestational weeks were higher, and they had less gestational
weight gain as compared with GDM women with IGT during
pregnancy or with normal glucose after delivery (Table 1).
The offspring of GDM mothers diagnosed with diabetes
during pregnancy or after delivery had shorter gestational
age and were more often premature and large for gestational
age at delivery compared with those of GDM mothers with
IGT during pregnancy or with normal glucose after delivery.
However, offspring of GDM mothers diagnosed with diabetes
after delivery had higher mean values of
