Hung TH, Hsieh TT, Shaw SW, et al. - Researchers conducted this retrospective cross‐sectional study to highlight risk factors for gestational diabetes mellitus (GDM) in women with dichorionic (DC) twins and to determine the connection between GDM DC twins and adverse maternal and perinatal outcomes in a large homogeneous Taiwanese population. This investigation was carried out on 645 women with DC twins, excluding pregnancies complicated by one or both fetuses with demise (n = 22) or congenital anomalies (n = 9), who gave birth after 28 complete gestational weeks between January 1, 2001, and December 31, 2018. Independent risk factors for GDM in women with DC twins were maternal age > 34 years and pre‐pregnancy BMI > 24.9 kg/m². The pregnancy and neonatal outcomes for women with GDM DC twins are identical to those for women with non-GDM DC twins, except for an approximately two-fold increased risk of NICU admission of newborns.
