GSTM1 and gestational diabetes: Compared to women with NGT, those with GDM exhibited significantly higher FBG, WBC count, neutrophil count, RBC count and Hb concentration (120 ± 11 vs. 125 ± 10 g/L in T1, 112 ± 10 vs. 115 ± 9 g/L in T2, 110 ± 12 vs. 115 ± 12 g/L in T3, all P < 0.001) throughout pregnancy (all P < 0.05), increased first-trimester blood pressure, creatinine, UA, TG, and HDL (all P < 0.05), second-trimester FBG, 1-h blood glucose (BG), 2-h BG, HbA1c, FINS, and HOMA-IR (all P < 0.001), and third-trimester diastolic blood pressure, creatinine, and TG (all P < 0.05).
