A definition and operational framework for health numeracy.

Area of Science:

• Public Health
• Health Communication
• Behavioral Science

Background:

• Health numeracy is often conflated with or subsumed under health literacy.
• Limited research has focused on health numeracy as a distinct construct.
• The importance of quantitative health skills is increasingly recognized.

Discussion:

• This paper addresses the gap in the literature by proposing a formal definition of health numeracy.
• It introduces clarifying categories to delineate the scope of health numeracy.
• This work aims to establish health numeracy as a recognized field of study.

Key Insights:

• Health numeracy requires a definition separate from health literacy to advance research.
• A clear definition and categorization will facilitate focused research efforts.
• This foundational work supports the development of the health numeracy field.

Outlook:

• Future research can now build upon a defined framework for health numeracy.
• This will enable a deeper understanding of individuals' quantitative health skills.
• The proposed definition and categories will guide the evolution of health numeracy research.
