  1. GDM Gestational diabetes
  2. aThe analysis of Cox regression was used to determine the RR and 95% confidence interval
  3. Model 1: Adjusted for age (continuous)
  4. Model 2: Additional adjustment were made for physical activity (inactive/moderately inactive/moderately active/active), education (high school graduate/university graduate), occupation status (housewife/employee), family number (continuous), history of stillbirth (yes/no), history of preterm delivery (yes/no), history of cesarean (yes/no), history of abortion (yes/no), pregnancy number (≤2/≥3) and baseline-BMI (continuous)
  5. Model 3: Additional adjustment were made for maternal weight gain (continuous)
