Evaluating Health Literacy and the Intersection of Public Policy

Abstract

Health literacy (HL), is how people find, understand, and use information to make informed health-related decisions. HL is a determinant of individual and population health. This article examines the intersection of HL and public policy, and discusses how strategic policymaking can enhance HL and improve health outcomes. Drawing on theoretical frameworks such as Nutbeam’s Model of Health Literacy, the Elaboration Likelihood Model, and the Theory of Planned Behavior, we explore how HL influences health behaviors, healthcare utilization, and patient engagement. We also review global policy initiatives, including national HL strategies in the European Union, Australia, China, and the United States. Case studies and public health campaigns, such those related to tobacco control and COVID-19 communication efforts, are analyzed to illustrate best practices and the effectiveness of policy. Despite progress, significant challenges persist, including health disparities, misinformation, and barriers to policy implementation. We conclude with recommendations to strengthen HL through education, accessibility, stakeholder collaboration, and media literacy. A systems-level approach is crucial for reducing health inequities and promoting informed decision-making across diverse populations.
