Policy-driven and Health Discourse Reconstruction: The Logic of Public Issues Construction in the Year of Weight Management——Discourse Network Analysis Based on Policy Texts and Media Reports

Abstract

Abstract: This study focuses on the policy practice of weight management year, and explores the construction logic of health issues in national governance and social response by analyzing the semantics of policy texts and the discourse network of media reports. The research shows that the policy takes the agenda setting of multi-sectoral coordination as the core, promotes weight management from individual health problems to the level of public governance, and the discourse practice highlights the instrumental rationality and humanistic care. It not only constructs a standardized intervention framework through quantitative indicators and technical tools, but also faces the public's questioning of the individual narrative of health responsibility. Media communication affects public cognition in the game of scientific authority, lifestyle and risk warning. Mainstream media constructs professional credibility with medical evidence, and social media deconstructs a single health standard with user-generated content. The interaction between the two promotes the penetration of policy target society, but also gives rise to communication deviations such as data anxiety and weight stigma. Public discourse is constrained by structural factors, forming a bottom-up reconstruction of the policy agenda. The study puts forward the interactive relationship between policy-driven, media game and public reconstruction, and reveals the dual reconstruction path of health discourse in technological empowerment and cultural change, with a view to providing theoretical and practical reference for optimizing health communication strategies and improving weight management policies.
