  2. bReference group—women that reported no morning sickness; were not unwell during the pregnancy; had a straight-forward pregnancy; or, experienced a complication free pregnancy
  3. cAdjusted for factors from early pregnancy: age, highest education, parity reported at the 1st antenatal visit
  4. dAdjusted for demographic factors reported at the 21-year FU: marital status, satisfaction with marital relationship, family income
  5. eAdjusted for clinical measures: BMI measured at 21-year FU, anxiety or depressive symptoms (DSSI) ever during the FU phases
