Magazines 64% 47%
Books or Brochures 62% 45%

The Bottom Line

  • Only 12 percent of adults have Proficient health literacy. In other words, nearly 9 out of 10 adults may lack the skills needed to manage their health and prevent disease.

  • Fourteen percent of adults (30 million people) have Below Basic health literacy. These adults are more likely to report their health as poor (42 percent) and are more likely to lack health insurance (28 percent) than adults with Proficient health literacy.

27

Measuring Health Literacy

Measures of health literacy at the individual level were developed in the 1990s:

  • Rapid Estimate of Adult Literacy in Medicine (REALM)
  • Test of Functional Health Literacy in Adults (TOFHLA and S-TOFHLA)
28

Measuring Health Literacy

  • Health literacy measures based on functional literacy do not capture the full range of skills needed for health literacy.
  • Current assessment tools (for populations and individuals) cannot differentiate among:
    • Reading ability
    • Lack of health-related background knowledge
    • Lack of familiarity with language and materials
    • Cultural differences in approaches to health.
29

Who Is at Risk?

  • The problem of limited health literacy is greater among:
    • Older adults
    • Those who are poor
    • People with limited education
    • Minority populations
    • Persons with limited English proficiency (LEP)
30

Who Is at Risk?

  • Many of the same populations at risk for limited health literacy also suffer from disparities in health status, illness (including heart disease, diabetes, obesity, HIV/AIDS, oral disease, cancer deaths, and low birth weight), and death.

Health Literacy: Use of Preventive Services

Persons with limited health literacy skills* are more likely to skip preventive measures such as:

  • Mammograms
  • Pap smears
  • Flu shots

*As defined by these studies

32

Health Literacy: Knowledge About Medical Conditions and Treatment

Persons with limited health literacy skills:

  • Are more likely to have chronic conditions and less likely to manage them effectively.
  • Have less knowledge of their illness (e.g., diabetes, asthma, HIV/AIDS, high blood pressure) and its management.
33

Health Literacy: Hospitalization and Health Status

Persons with limited health literacy skills:

  • Experience more preventable hospital visits and admissions.
  • Are significantly more likely to report their health as "poor."
34

Health Literacy: Healthcare Costs

  • Predicted inpatient spending for persons with inadequate health literacy (measured by the S-TOFHLA) was $993 higher than that of persons with adequate health literacy.
  • An earlier analysis found that the additional healthcare resources attributable to inadequate health literacy were $29 billion (assuming that inadequate literacy was equivalent to inadequate health literacy):
    • This number would have grown to $69 billion if even one-half of marginally literate adults were also considered not health literate.

Health Literacy at HHS

36

Commitment to Health Literacy

  • Secretary Leavitt: Prevention and health information technology (IT) are two big priorities for the healthcare system.
  • Secretary Thompson's Workgroup on Health Literacy
    • Prevention: A Blueprint for Action
      "It is critical that individuals have access to health information in a way they can understand and make appropriate health decisions."
37

Office of the Surgeon General

  • Health literacy improvement is one of the Surgeon General's seven public health priorities.
  • "Health literacy is the currency of success for everything I am doing as the Surgeon General."
    • —Dr. Richard Carmona in his speech to the AMA
          House of Delegates, June 2003.

Funding

  • NIH program announcement: Understanding and Promoting Health Literacy
    • Three annual submission dates 2004–2006
    • Thirteen sponsoring institutes and offices with AHRQ
    • NIH spending in FY05 for these grants is close to $3 million, and it will total more than $8 million during the life of the awarded grants.
  • HRSA provides funding to community-based organizations for health literacy activities and research.
