Co designing evidence based resources for the twin and family community

Project Details

We seek to improve the lives of multiple-birth families by undertaking research of particular relevance to them, nurturing community connection, providing evidence-based resources, and advocating on their behalf. Twins, multiples and their families face significant challenges during pregnancy, birth and early life, placing long-term pressure on the whole family.

Twins and multiples are much more likely to be born pre-term (64%) compared to singletons (7%). The proportion of babies born with low birthweight is also higher amongst twins (54%) and multiples (98%), while remaining only at 5% in normal pregnancies. Therefore, their median length of stay in hospital is remarkably different: 6, 30 and 3 days respectively.

This project aims to inform future research, public discussion and policy-making on the social and health inequalities faced by twins, multiples and their families. It will provide pathways for engagement between researchers, clinicians and parent organisations, to develop a white paper with contributions from a variety of experts in each of those stakeholder groups, providing a space for collective learning and sharing of knowledge specific to the Australian context.
