INS and gestational diabetes: Insulin therapy was more frequently used to control GDM in women with increased fasting glucose levels (early FPG and late FPG groups) and was associated with body weight (ρ = 0.19, p < 0.001), BMI (ρ = 0.24, p < 0.001) and glycated hemoglobin at the time of GDM diagnosis (ρ = 0.30, p < 0.001).
