  1. SD, standard deviation; CI, confidence interval.
  2. *Multiple linear regression models were used with adjustment for baby’s sex, gestation at delivery, maternal age, education, parity, smoking history, height, BMI at 27 weeks gestation, coffee consumption and depression.
  3. **There were 2 women with missing information on length and head circumference.
  4. ***There were 14 women with missing information on placental weight.
