Title: Literacy, health education, health literacy and health outcomes

Literacy, health education, health literacy and
health outcomes How do they fit?
  • Don Nutbeam
  • University of Sydney

2
What is literacy?
  • What is it?
  • Functional literacy is a measure of a persons
    ability to read basic text and write a simple
    statement relevant to everyday life
  • Why do we care?
  • Those who are functionally literate are able to
    participate more fully in society, and are able
    to exert a higher degree of control over everyday
    events
  • Literacy levels are related to public health
    outcomes

Distribution of Global Adult Illiterate
Population (15 and over) by Region, 2005-2007
(Total Number of Adult Illiterate Population
775 millions)
"More than two-thirds of the world's adult
illiterates live in Asia and the Pacific Region"

Rates of illiteracy are higher in SW Asia,
especially in India, Bangladesh and

children that would be born per woman if she
were to live to the end of her child-bearing
years and bear children at each age in
accordance with prevailing age specific fertility
rates.

Literate People Tend to Live Longer
Life expectancy at birth is the number of years
newborn children would live if subject to the
mortality risks prevailing for the cross-section
of population at the time of their births

Commission on Social Determinants of Health
  • Education and the life-course
  • Removing the numerous barriers to achievement of
    primary education will be a crucial part of
    action on the social determinants of health
  • Literacy has central role in health equity in
    countries rich and poor

Literacy and health
  • Relationship between low literacy and a range of
    health related outcomes well established
  • Some indirect effects
  • Employment
  • Income
  • Some direct effects
  • Engaging in preventive health practices
  • Early detection of disease
  • Access to health care
  • Management of chronic disease
  • Key messages
  • Literacy is a public health goal
  • Achieving the MDGs in relation to literacy will
    have major public health benefits

10
A brief history of health education (1)
  • A central component of efforts to promote health
    an prevent disease throughout this century
  • Evolved from health propaganda campaigns focused
    on eradication of infectious disease into healthy
    lifestyle programs
  • Found to be most effective in reaching and
    influencing the most literate, best educated and
    economically advantaged in the community

11
Contemporary health education how to maximise
impact on health outcomes
  • New generation of health education focussed on
    the social context of health decision-making, the
    development of personal skills and capabilities
  • Informed by evolving psycho-social theory
  • Supported by more sophisticated understanding of
    media, and adaptation of social marketing
    techniques to health campaigns
  • Greater understanding of the need to
    contextualise communication, making it relevant
    to defined target populations, and needs of low
    literacy populations
  • Well documented successes in improving knowledge
    and health related skills, and in changing health
    behaviours relevant to the MDGs, for example in
    relation to smoking, food choices, physical
    activity and sexual practices

12
The emergence of the concept of health literacy
  • Literacy is context and content specific more
    accurate to talk about literacies for example
  • financial literacy,
  • consumer literacy,
  • IT literacy and,
  • health literacy
  • Even where a person has advanced literacy skills
    their ability to obtain, understand and apply
    information about health may be poor hence
    findings indicating high prevalence of poor
    health literacy from US, Australian and Canadian
    studies.

13
What is health literacy?
  • Health literacy represents the cognitive and
    social skills which determine the motivation and
    ability of individuals to gain access to,
    understand, and use information in ways which
    promote and maintain good health
  • Health literacy means more than being able to
    read pamphlets and make appointments. By
    improving peoples access to health information
    and their capacity to use it effectively, health
    literacy is critical to empowerment

Health literacy public health origins in
Australia
15
Australias health literacy goals 1993
  • To achieve the goals of the Australian Language
    and Literacy Policy
  • To enhance knowledge and improve health literacy
    to enable people to make informed choices about
    their health
  • To enhance knowledge and improve health literacy
    to enable people to take an active role in
    bringing about changes in the environments that
    shape their health

    Literacy in Goals and Targets for Australias

19
How would this look in practice?
  • Schools and health literacy strong and
    consistent evidence exists for
  • providing a comprehensive and integrated health
    education program for students, based on
  • Content that includes both basic personal health
    information, and exposure to the influence of
    social, economic conditions, and the role of the
    media
  • Teaching and communication methods based on well
    researched psycho-social theory and effective
    classroom interaction
  • Outcomes focus on enhanced health literacy
    through improved knowledge and development of
    personal and social skills

20
Schools and health promotion
  • Efforts to promote health literacy will be
    greatly enhanced by
  • Adopting organisational practices which
    complement and support the teaching program
  • Offering a supportive social environment for
    students
  • Fostering links with health resources in the
    community, including optimal use of school health
    services
  • creating a safe an secure physical environment

21
Summary remarks What is the state of the
science
  • Good research in health care settings linking
    poor health- related literacy with range of
    clinical outcomes
  • Some intervention trials in health care settings
    demonstrate potential effectiveness and cost
    savings
  • Good research on the efficacy of modern health
    education in schools and other settings, but less
    developed research on the intermediate concept of
    health literacy in these settings (eg adult
    education, E-learning)
  • Progress in development of measures of
    health-related literacy in clinical settings, but
    limited progress in development of comprehensive
    measures

22
Summary remarks where to from here in practice
development
  • Health literacy fundamentally dependent upon
    levels of basic literacy in the population
    essential to make policy and practical program
    links between these MDGs,
  • Developing self confidence to act on knowledge
    and the ability to support others requires more
    personal, and community-based educational
    outreach incorporation of adult learning
    principles and health promotion concepts
  • Promoting greater critical health literacy and
    well informed independent decision-making
    requires recognition of social and environmental
    context to decision-making, enabling individuals
    to address structural barriers to health

23
Summary remarks What needs to be done first?
  • Develop programs that are context and content
    specific in priority areas in relation to MDGs
  • Improving capability to obtain, understand and
    apply relevant information through
  • Maternal and child health programs
  • School Health programs
  • Cross-sectoral collaboration on adult literacy
    programs

24
Skilled for Health (UK)
  • Skilled for health
  • Integrates goals of health improvement with
    improving literacy, language and numeracy (LLN)
    skills of adults
  • Cross government-voluntary sector initiative
    combines adult LLN learning with peoples wish
    for a better understanding of health
