Résumé
Aims: Health literacy is considered a key social determinant of health. It plays an important role in the prevention and management of non-communicable diseases (NCDs), contributing to better health and well-being. Therefore, the overall aim of the health literacy focus (Action) within the European Joint Action to prevent NCDs (JA PreventNCD) is to promote general, digital, mental and organizational health literacy to improve health outcomes and counteract NCD-related health inequities in Europe. This paper presents a rational and methodological approach for strengthening health literacy in Europe.Methods: The Action will be implemented through collaboration among 13 EU Member States and three non-EU Member States, using both quantitative and qualitative research approaches including questionnaire-based surveys, literature reviews, in-depth interviews, and focus groups, as well as stakeholder and user involvement. The implementation will be guided by a Health Literacy Approach to Theory of Change and carried out in three main phases: 1) project development, 2) data collection, data-analysis and tool development, and 3) recommendations for policy, research, and practice and dissemination.Conclusions: The project supports participating countries in conducting a comprehensive national-level situation analysis and provides a solid foundation for further developing national health literacy-related policies, strategies or action plans. The project's expected outcome will contribute to promoting general, digital, mental and organizational health literacy in the prevention of NCDs in Europe. A Theory of Change and a coordinated approach facilitate the development of shared platforms, such as the European Health Literacy Arena, which help maintain collaboration and visibility beyond the lifetime of the project.
