Background:

  • A significant body of research links poor education and low literacy to adverse health outcomes and premature mortality worldwide.
  • The intricate relationships between socioeconomic factors, literacy, and health remain incompletely understood.
  • Existing health literacy frameworks may not fully capture the multifaceted nature of these complex associations.

Purpose of the Study:

  • To propose an expanded model of health literacy encompassing fundamental, science, civic, and cultural literacy domains.
  • To evaluate the utility of this expanded model in analyzing public health communication during a crisis.
  • To inform the development of improved health communication strategies and assessment tools.

    • The proposed four-domain health literacy model provides a robust framework for analyzing health communication.
    • The model effectively illustrates how different literacy aspects influence public understanding during health crises.
    • Selected public discourse analysis demonstrated the model's utility in identifying communication challenges.

    Conclusions:
