Abstract The burden of ill health is not carried equally, children and young people with experiences of childhood social care (CSC), e.g. kinship, foster, residential or ‘out-of-home’ care, are affected by multiple cumulative disadvantages and experience high inequalities in health compared to the rest of the population. CSC, and the adversities often associated with it, are linked to health problems that persist into adulthood and adversely affect education, employment, and the future European society. Public and policy interest in improving outcomes for CSC recipients has increased markedly, as has research on the association between CSC and life outcomes. But current research is siloed, with limited comparative perspective and has not led to a strong evidence base to inform policy and practice. Wider international networks to connect research, practice and policy are needed to change this. The objective of the workshop is to bring together evidence on health inequalities between people with and without CSC experience across Europe. The panel will set the scene for the discussion by raising questions that stem from their work for the audience to respond. We will ask the audience to engage with these questions based on their experience (e.g. academic, clinical or other professional). The real-time reactions will be collected via Mentimeter during presentations, moderated and fed back to the audience and panel for discussion. This will allow us to collect diverse responses across countries and from different professional perspectives, providing learning and insights for both the panel and audience. The added value of a EUPHA workshop is the high-profile European level attention on this population. A spotlight on CSC experiences bringing together evidence from topic experts and health practitioners committed to improving childhood health inequalities across Europe and will foster a strong foundation for future collaborations and comparative research. The format is interactive and will include an introductory video of lived experiences of CSC to put a human face on this topic. We will then hear 4x5 minute expert presentations from social epidemiologists, health and social care professionals (20m) followed by a moderated discussion with the audience (35m). The presentations cover research across Europe, consider how inequalities accumulate across the life course to place children in care settings and identify where gaps in services fail children. MA sets the scene by asking what the international evidence is telling us about the health of people with CSC experiences. VS explores the accumulation of disadvantage across the life-course and intergenerational experiences of CSC. HF uses the Swedish example to ask why welfare services are not meeting the health needs of children. Finally, SS will consider solutions: what additions support is required for health practitioners dealing with children in care settings and what can/cannot be achieved from within the doctor’s office? Key messages • Participants will gain new insights on the health of children with social care experience from each other by sharing evidence and discussing key questions from diverse perspectives across Europe. • The workshop provides a foundation for participants to build future international networks and comparative research that will lead to a strong evidence base to inform policy and practice.
