Barwon Infant Study (BIS)

The Barwon Infant Study (BIS) is a pre-birth population derived cohort with over 1000 pregnant women recruited between 2010 and 2013. This study was designed to follow children born to the recruited mothers and observe them as they grow. BIS is an investigation into the early life origins of a range of non-communicable diseases in the modern environment.

BIS is being conducted as a partnership between Barwon Health, Deakin University and the Murdoch Children’s Research Institute. BIS is primarily funded by the National Health and Medical Research Council (NHMRC).

Study focus
  • BIS Immune (early life environment modifies postnatal immune programming and the risk of allergic disease)
  • BIS Respiratory (identify environmental exposures that may impact on foetal lung growth and development
  • BIS Cardiovascular (factors contributing to the development of atherosclerosis from birth onwards)
  • BIS Neurodevelopment (early life exposure to neurotoxicants and adverse childhood developmental outcomes)
  • BIS Food Allergy (investigate the relationship between low vitamin D status and food allergy)
