Researchers seeking locals who are planning a pregnancy

The MothersBabies Study is currently open for recruitment at St George Hospital. If you’re 18+ and planning a pregnancy in the next 12 months the team would love to have you involved!

The MothersBabies Study is investigating changes in the human microbiome from pre-pregnancy, through to your baby’s first birthday, to find out how our pre-pregnancy lifestyle impacts health and pregnancy outcomes. The study is aiming to recruit 2000 women from across NSW, and follow them for their pre-pregnancy, pregnancy and birth, and post-natal journey (approximately 3 years).

This study is entirely observational, and there is no treatment involved. To take part, you must be NSW-based female, at least 18 years old, and be planning to fall pregnant in the next 12 months (but not currently pregnant). Researchers will ask some questions about overall health and wellbeing and ask pregnancy-wellbeing questions as your pregnancy progresses. They will also conduct a small physical examination and ask you to provide a sample for microbiome analysis. Once your baby is born, they ask questions about their birth, ongoing development, and general wellbeing. They will also have a small physical examination at each visit you will also need to collect some samples from baby for microbiome analysis too.

You can sign up by emailing the research coordinators at To speak with one of the research midwives directly, call 02 9113 1832 during regular business hours.

This study has Human Research Ethics Approval, Number 2019/ETH00192
