  1. aThe larger sample size in the unadjusted analysis was due to less missing information by only pre-pregnancy BMI and outcomes
  2. b104 boys and 80 girls were not included in adjusted analyses due to missing values in covariates
  3. cAdjusted for maternal gestational weight gain, maternal age at conception, gestational weeks at birth, education, parity, folic acid intake during pregnancy, passive smoking and infant birth weight
