To maintain their own health and the health of their families and communities, consumers rely heavily on the health information that is available to them. This information is at the core of the partnerships that patients and their families forge with today?s complex modern health systems. This information may be provided in a variety of forms ? ranging from a discussion between a patient and a health care provider to a health promotion advertisement, a consent form, or one of many other forms of health communication common in our society. Yet millions of Americans cannot understand or act upon this information. To address this problem, the field of health literacy brings together research and practice from diverse fields including education, health services, and social and cultural sciences, and the many organizations whose actions can improve or impede health literacy. Health Literacy: Prescription to End Confusion examines the body of knowledge that applies to the field of health literacy, and recommends actions to promote a health literate society. By examining the extent of limited health literacy and the ways to improve it, we can improve the health of individuals and populations.

Health literacy : a prescription to end confusion

OBJECTIVE: To review the relationship between literacy and health outcomes DATA SOURCES: We searched MEDLINE, Cumulative Index to Nursing and Allied Health (CINAHL), Educational Resources Information Center (ERIC), Public Affairs Information Service (PAIS), Industrial and Labor Relations Review (ILLR), PsychInfo, and Ageline from 1980 to 2003 STUDY SELECTION: We included observational studies that reported original data, measured literacy with any valid instrument, and measured one or more health outcomes Two abstractors reviewed each study for inclusion and resolved disagreements by discussion DATA EXTRACTION: One reviewer abstracted data from each article into an evidence table; the second reviewer checked each entry The whole study team reconciled disagreements about information in evidence tables Both data extractors independently completed an 11-item quality scale for each article; scores were averaged to give a final measure of article quality DATA SYNTHESIS: We reviewed 3,015 titles and abstracts and pulled 684 articles for full review; 73 articles met inclusion criteria and, of those, 44 addressed the questions of this report Patients with low literacy had poorer health outcomes, including knowledge, intermediate disease markers, measures of morbidity, general health status, and use of health resources Patients with low literacy were generally 15 to 3 times more likely to experience a given poor outcome The average quality of the articles was fair to good Most studies were cross-sectional in design; many failed to address adequately confounding and the use of multiple comparisons CONCLUSIONS: Low literacy is associated with several adverse health outcomes Future research, using more rigorous methods, will better define these relationships and guide developers of new interventions

Literacy and health outcomes

The efficacy of behavioral interventions to modify dietary fat and fruit and vegetable intake: a review of the evidence.

▪ Abstract Our evolving understanding of how psychosocial and behavioral factors affect health and disease processes has been marked by investigation of specific relationships and mechanisms underlying them. Stress and other emotional responses are components of complex interactions of genetic, physiological, behavioral, and environmental factors that affect the body's ability to remain or become healthy or to resist or overcome disease. Regulated by nervous, endocrine, and immune systems, and exerting powerful influence on other bodily systems and key health-relevant behaviors, stress and emotion appear to have important implications for the initiation or progression of cancer, HIV, cardiovascular disease, and other illnesses. Health-enhancing and health-impairing behaviors, including diet, exercise, tobacco use, and protection from the sun, can compromise or benefit health and are directed by a number of influences as well. Finally, health behaviors related to being ill or trying to avoid disease or its...

Review and Analysis of Evaluation Measures Used in Nutrition Education Intervention Research

The authors explored changes in dietary behavior, nutrition knowledge, and parental support among inner-city, low-income, Hispanic American families. Thirty-eight families were randomly assigned to receive a 12-week, culture-specific dietary intervention or be in a control group. Results showed that parental support was related to changes in diet, nutrition knowledge, and attendance for both mothers and children. Dietary behavior changes (e.g., reduction in dietary fat) were seen only in the treatment group. Distribution of health-related pamphlets to the control group may have promoted cognitive changes (e.g., increased nutrition knowledge) seen in this low-literacy sample. Further research is needed to document behavioral changes after ethnic-specific interventions and the maintenance of those changes over time.
