• Public Health Policy

Background:

• Health literacy definitions are numerous and evolving.
• Restricted definitions create research gaps and limit inquiry.
• Current understanding necessitates expansion to encompass broader aspects of health literacy.

Purpose of the Study:

• Discuss challenges posed by narrow health literacy definitions.
• Identify missing elements in current health literacy research.
• Advocate for an expanded framework for health literacy.

Main Methods:

• Literature review and conceptual analysis of health literacy definitions.
• Examination of existing research gaps and limitations.
• Argumentative synthesis of evidence for a broader scope.

Main Results:

• Restricted definitions hinder comprehensive research and understanding.
• Key missing elements include health professionals' communication skills and health-related tasks/texts.
• System-level factors (norms, policies) significantly impact health access.

Conclusions:

• An expanded definition of health literacy is crucial for advancing research and practice.
• Future research should integrate literacy skills, system demands, and health outcomes.
• Policy and institutional changes are necessary to improve access to health information and care.
