Aims: Women with a history of gestational diabetes mellitus (GDM) are likely to develop postpartum diabetes mellitus (DM) We examined women in the early stages of pregnancy who were at high risk of postpartum DM progression to establish a follow-up method for early detection. Methods: We performed the oral glucose tolerance test (OGTT) and identified predictive factors for postpartum impaired glucose tolerance (IGT) or DM in 77 women after GDM, for 2 years after delivery, retrospectively. Cutoff values for each factor were determined. We classified these women with GDM into four groups using these predictive factors and evaluated postpartum glucose intolerance (GI) in each group. Results: In total, 44.1% of the women with a GDM history had developed postpartum GI within 2 years. We determined three risk factors for postpartum GI: elevated glucose level 120 min after a 75-g OGTT (Glu120), elevated glycated hemoglobin (HbA1c) level at diagnosis, and perinatal complications. The cutoff Glu120 and the HbA1c level were 155 mg/dl and 5.3% (34 mmol/mol), respectively. Type 2 DM developed in 53.8% of women, and IGT developed in 38.5% of women within 2 years in groups with high Glu120 and high HbA1c. Conclusions: High-risk groups require careful follow-up observation. (C) 2018 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND license.
