 Presentation by Irving Rootman to SFU
   Class on Principles and Practices of
            Health Promotion
            October 4, 2010
Outline
   What is health literacy?

   How is it measured?

   How does it relate to aging?

   What impact does it have on older adults?

   What are the determinants of health literacy in older adults?

   How can be done to address health literacy in older adults?
What is health literacy?
   the ability to access, understand,
    evaluate and communicate information
    as a way to promote, maintain and
    improve health in a variety of settings
    across the life-course (CPHA Expert
    Panel on Health Literacy).


                     (Rootman and Gordon-El-Bihbety, 2008)
Literacy is…
   the ability to understand and use
    reading, writing, speaking and other
    forms of communication as ways to
    participate in society and achieve one’s
    goals and potential” (CPHA Expert Panel
    on Health Literacy)

     Health Literacy (Reading Proficiency) and
     Health-Related Outcomes (I.O.M., 2004)

   More likely hospitalization and negative disease outcomes

   Higher rates of diabetes

   Poorer Diabetes Control

   Inappropriate medication use and compliance with physician
    orders

   Less use of preventive services and less care seeking

   Difficulties using health care system

   Less expression of health concerns

   Higher mortality
Low health literacy and premature
mortality among older adults
   A recent U.S. study found that older adults with
    inadequate and marginal health literacy levels had a
    50 per cent higher mortality rate over a five-year
    period than those with adequate skills. (Barker et al.,
    2007)

   Low health literacy was the top predictor of mortality
    after smoking, and was a more powerful variable
    than both income and years of education.

   Another study found that limited literacy was
    independently associated with a nearly two-fold
    increase in mortality in the elderly. (Sudore, et al,
    2006)
Other literacy-related health
outcomes for older adults

   Older adults with low literacy are more likely
    to report difficulties with activities of daily
    living, few accomplishments because of their
    physical health, greater pain interfering with
    work, and have less knowledge about
    diseases

              (Rootman and Ronson, 2005; Friedman, 2006)
Challenges faced by Older Adults
with Low Literacy (IOM, 2007)

   Stigma
   Increasing literacy demands
   Isolation
   Poverty
   Perceptual or cognitive difficulties
   Difficulty maintaining their health, safety, independence and
    self-esteem
   Programs exclude older adults or don’t meet their needs
   Perceived relevance of adult education
   Health education materials tend to require strong literacy skills
   Health workers are not trained to recognize literacy deficits

Adults aged 66 and over (CCL, 2008)

Predictors of Health Literacy in
Older Adults
   Sub-sample of older adults (n=2,979) from 2003 IALSS
    (Canadian survey)

   Formal education, life-long and life-wide learning
    enabling factors exhibited the most robust associations
    with health literacy among older adults

   Concluded that Programs and policies that encourage
    life-long and life-wide educational resources and
    practices are needed


                                 (Malloy-Weir et al., 2010)
What can be done?
   Very few rigorous evaluations (IOM,
    2004; CPHA 2008)
Pignone Review (2005):
Methods
   Systematic review of interventions
   Included controlled and uncontrolled studies
   Searched variety of data sources
   Covered 1980-2003
   Found 20 articles with interventions to
    improve health among people with low
    literacy
   Abstracted data from articles and assessed
    quality
Pignone Review: Findings
   Effectiveness mixed

   Variation in research quality and outcome
    measures

   Only 5 studies examined interaction between
    literacy level and effect of intervention; also
    found mixed results
Pignone Review: Conclusions
   Several interventions have been developed to
    improve health for people with low literacy

   Limitations of studies make drawing
    conclusions difficult

   Further research needed to understand types
    of interventions that are most effective and
    efficient for overcoming literacy-related
    barriers to good health
King Review (2007): Methods
   focused search and review of the academic
    literature related to health literacy
    interventions

   focused search and review of the grey
    literature related to health literacy
    interventions in Canada and around the world

   Key informant interviews
King: Findings
   Majority of health literacy interventions involved
    accessing and understanding, with very few focused
    on appraising or communicating health information

   Very limited information was found about the
    effectiveness of health literacy interventions

   Some evidence to support the finding and general
    understanding that a participatory educational and
    empowerment approach is effective
King: Conclusions
   Barriers to evaluation of programs were time,
    money and lack of provider expertise

   a number of areas of further investigation are
    suggested including:
       health literacy interventions focused on appraising
        health information
       cultural issues
       health care professional training
       sources of health information
       learner and patient perspectives
Clement Review (2009):
Methods
   Systematic review of randomized and quasi-randomized
    controlled trials focused on complex interventions for
    people with limited literacy or numeracy

   Searched eight databases from start to 2007

   Checked references and contacted key informants

   Two reviewers assessed eligibility, extracted data and
    evaluated study quality
Clement: Findings
   2734 non-duplicate items, reduced to 15 trials
   Two interventions for health professionals,
    one literacy education and 12 health
    education and management; most in North
    America
   Most (13/15) reported at least one significant
    difference in primary outcome favoring
    intervention group
   Knowledge and self-efficacy most likely
    outcome improvement
Clement: Conclusions
   A wide variety of complex interventions for
    adults with limited literacy are able to
    improve some health-related outcomes

   Review supports wider introduction of
    interventions for people with limited literacy,
    particularly within an evaluation context
Strategies for Addressing Health Literacy




1.   Improve skills required to be health literate

2.   Provide services appropriate for people with all
     skill levels
An Example of Strategy #1



   Mental Fitness for Life is an 8-week series of intensive
    workshops based on grounded research that includes the
    following topics: Goal Setting; Critical Thinking; Creativity;
    Positive Mental Attitude; Learning; Memory; and Speaking your
    Mind.

    Evaluations suggest that the program has a positive impact on
    health, and that there is a need to promote mental fitness, like
    physical fitness, as a health promoting behavior that supports
    the progressive development of the individual across the
    lifespan.

   For more information see: Cusack et al., 2003 and Cusack and
    Thompson, 2005)
A Second Example of Strategy #1

   The Computer for Elder Learning project used free
    computer training as outreach tool to recruit older
    adults for literacy skills upgrading

   Although it failed to recruit people with low literacy
    skills, participants reported that they were reading
    and writing more due to the computer and more
    confident about their reading and writing skills.

    services appropriate for people with all skill levels

   The provision of opportunities for lifelong learning may be
    particularly important

   There are some innovative efforts in Canada to address the health
    literacy needs of older adults

   Most of the efforts are short-term and not well supported

   Few of them have been evaluated rigorously
