Insulin Resistance in GDM A1 vs Healthy Pregnancy: A Comparative Study Using METS-IR and TyG Index

Women with GDM A1 exhibited higher insulin resistance throughout pregnancy compared to healthy controls. Early-pregnancy METS-IR and TyG indices were associated with GDM A1 diagnosis but not with delivery characteristics or fetal parameters. Due to the influence of BMI changes during pregnancy, METS-IR may not be a reliable surrogate marker of insulin resistance in this population.
