Paraoxonase activity, insulin levels, HOMA-IR, demographic features and anthropometric measurements were evaluated. Results: The mean paraoxonase activity was significantly diminished in patients with GDM (p:0,004). Insulin level and HOMA-IR were significantly higher in GDM patients (p:0,004 and p:0,001; respectively). The mean interval between present and previous pregnancy was significantly shorter in patients group (p:0,004). There was a significant correlation between PON1 activity and serum LDL, HDL levels and weight gained during pregnancy (p:0,001,p<0,001 and p:0,002; respectively) but not with weight and parity. However HOMA-IR was significantly correlated with weight and parity (p:0,001 and p:0,002; respectively). Discussion: Diminished PON1 activity and enhanced oxidative stress accompany to insulin resistance in the pathogenesis of GDM. Oxidative stress is associated with weight gained during first 2 trimesters of pregnancy rather than obesity.eninfo:eu-repo/semantics/closedAccessGestational DiabetesInsulin ResistanceParaoxonase ActivityArticle2946536572-s2.0-84896700396N/A
