Literacy and health are deeply influential in social participation, utilisation of social resources and quality of life. This paper discusses interacting discourses and common conceptual points shared by the adult literacy and public health fields and situates how the sub-field at the intersection of these two domains, known as ‘health literacy’, is constructed and enacted. Emerging approaches that recognise the convergence of education and health within international policy, research and in practice are articulated. The paper argues a case for re-thinking the literacy-health connection from a cross-sectoral perspective and for more effective approaches furthering the interests of both life-long learning and wellbeing.
