You should also be able to answer yes to at least one of these statements:

  • My BMI at booking was greater than 29
  • I was referred to (or I was offered but declined referral to) a dietician or weight management services due to being overweight or obese
  • I was placed under consultant-led care due to being overweight or obese
  • I was advised to take 5mcg of folic acid per day due to being overweight or obese
  • I was advised that due to being overweight or obese I should have a glucose tolerance test and/or additional growth scans.

If you are currently working, or were employed prior to pregnancy, as a healthcare professional, you will not be able to take part.
