Background: Children and youth are an important population group requiring specific policies to address their needs. In Australia, most children and youth are doing well, however, certain equity groups are not. To address health equity in policy, applying a social determinants of health approach is considered best practice. For over 10 years governments in Australia have been called upon to address the social determinants of health, however, there has been limited action. Health and education departments are typically most involved in policy development for children and youth. To date, there have been limited systematic analyses of Australian child and youth health policies, and selected education wellbeing policies, with a social determinants of health and health equity focus and this study aims to contribute to addressing this gap. Methods: We conducted a policy analysis study across 26 Australian child and youth health policies, and selected education wellbeing policies. We used an existing prior coding framework with a social determinants of health and health equity lens to understand the extent to which the social determinants of health and heath equity were addressed. Policies were dated 2009 onwards. Results: Across 26 selected policies only 10% of strategies addressed the social determinants of health. We report on the social determinants of health addressed, to some degree, which includes early childhood development, education, parental workplace conditions, healthy settings, and housing, and to a lesser extent, public transport and regulation. Conclusions: This study demonstrates a lack of policy action on the social determinants of health. Rather, the application of a siloed, and predominantly acute care approach. However, there is recognition of equity across all policies; an emphasis on housing as a determinant of health; and a link between health and education departments through education wellbeing policies, specifically addressing the issue of mental health.
