|• This form may be completed by |
• pregnant women
• lead maternity carers
• Completion of this form enables researchers to make contact and discuss the study in more detail. It does not commit women to take part in the study.
• We need to hear from women as early in pregnancy as possible, and this must be before reaching 16 weeks pregnant.

We want to find out if by giving pregnant women a specific probiotic we can:
- Stop infants developing eczema and allergy
- Help pregnant women’s health by preventing:
o Some vaginal infections
o A type of diabetes that occurs only in pregnancy (gestational diabetes)
What are probiotics?
Probiotics are helpful microbes that occur naturally in many foods such as yoghurt. They provide health benefits.
What does the study involve?
- Participants in this study need to take one study capsule each day starting when 14-16 weeks pregnant and continuing throughout the remainder of their pregnancy and for 6 months after birth while breast feeding.
- Half the participants will take study capsules containing the study probiotic. They contain one specific probiotic strain which is not genetically modified and was produced in a Halal compliant manner.
- The other half of the participants will receive study capsules that do not contain probiotics. These capsules are called a “placebo”. The placebo capsules contain Maltodextran only instead of the probiotic.
- Neither you nor the researchers know who is having the probiotic capsules and who is having the placebo until after the study is completed.
- After birth the baby would not receive the study capsules.
- Participants will take part in 5-6 study visits starting when they are 14-16 weeks pregnant and finishing when their baby is 1 year old.
- Study visits involve a range of questions and measures including one set of blood tests and two sets of vaginal swabs during pregnancy. We will also be testing participants, their baby and the baby’s father for allergies and checking your baby’s skin for eczema.
- We will provide parking and petrol vouchers when participants need to travel to attend study visits. Home visits will be arranged for some parts of the study (e.g. just after birth).
Who can take part in this study?
Women taking part in the study need to:
1. Be less than 16 weeks pregnant
2. Either they (the pregnant woman) or the biological father of the unborn child must have had eczema, asthma or hay fever that was treated by a doctor at some time in the past
3. Live in, and plan to deliver in the Wellington area
Live in, and plan to deliver in the Auckland area
If you are unsure if you would meet all of the above criteria please contact us.
Please note: A range of other criteria apply to women who wish to join the study.
These will be assessed over the phone by the research staff after women register interest in the study.
If you think you may be interested in taking part in this study please contact us as early in your pregnancy as possible by expressing your interest here
What are the benefits of taking part in this study?
Being involved in this study means that:
- You may be healthier during pregnancy (although there is no guarantee of this).
- Your child may not develop eczema (although there is no guarantee of this).
- You would be contributing to important research which may help us to gain new ways of preventing illnesses in pregnancy and in young children
Who is conducting this study?
This research is being conducted in two centres, (Wellington and Auckland), and is being run by a group of experienced researchers collaborating across several different institutions. Several members of this group have successfully completed a similar large scale research using probiotics in pregnancy women and infants in the past.
