PG - 108421 LID - S0168-8227(20)30674-4 [pii] LID - 10.1016/j.diabres.2020.108421 [doi] AB - AIMS: Diagnostic criteria for type 2 diabetes mellitus (T2DM) applied to women with gestational diabetes mellitus (GDM) may predict postpartum T2DM but requires validation. METHODS: Women with GDM aged >/= 18-years were prospectively evaluated 6-12 weeks after delivery at Tygerberg Hospital, Cape Town, South-Africa (November 2015- December 2018). Glucose status at GDM diagnosis was categorized into i) International Association for Diabetes in Pregnancy Study Group (IADPSG) T2DM (fasting glucose >/= 7 mmol/L and/or 2hr-glucose >/= 11.1 mmol/L) or ii) modified National Institute for Care Excellence (NICE) GDM (fasting glucose >/= 5.6 mmol/L-6.9 mmol/L and/or 2hr-glucose >/= 7.8 mmol/L-11 mmol/L) and compared with postpartum OGTT. RESULTS: IADPSG T2DM and NICE GDM was present in 35% (n = 64) and 65% (n = 117) of the 181 women who completed the 8 +/- 2 weeks postpartum evaluation respectively. Postpartum, the prevalence of T2DM and prediabetes was 26% (n = 47/181) and 15% (n = 28). Antenatal IADPSG T2DM categorization identified 31/47 women with postpartum T2DM (sensitivity 75%; specificity 48%). All of the modified NICE GDM category women who developed T2DM (n = 16/117) had elevations of both fasting and 2hr-glucose values antenatally. CONCLUSION: The utility of the IADPSG T2DM criteria to predict T2DM postpartum is confirmed. Women with both fasting and 2hr-glucose values above GDM cut-offs emerged as another high-risk category.
