What Is Health Literacy?
The definition of health literacy was updated in August 2020 with the release of the U.S. government’s Healthy People 2030external icon initiative. The update addresses personal health literacy and organizational health literacy and provides the following definitions:
- Personal health literacy is the degree to which individuals have the ability to find, understand, and use information and services to inform health-related decisions and actions for themselves and others.
- Organizational health literacy is the degree to which organizations equitably enable individuals to find, understand, and use information and services to inform health-related decisions and actions for themselves and others.
These definitions are a change from the health literacy definition used in Healthy People 2010 and Healthy People 2020: “the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions.”
The new definitions:
- Emphasize people’s ability to use health information rather than just understand it
- Focus on the ability to make “well-informed” decisions rather than “appropriate” ones
- Acknowledge that organizations have a responsibility to address health literacy
- Incorporate a public health perspective
From a public health perspective, the organizational definition acknowledges that health literacy is connected to health equity. Health equity is the attainment of the highest level of health for all people. We will achieve health equity when everyone has the opportunity to be as healthy as possible.
In the March 2021 article, “Updating Health Literacy for Healthy People 2030: Defining Its Importance for a New Decade in Public Health,” Santana and colleagues provide the rationale and process for updating the definition of health literacy.
