Needed action in health literacy.

Insights for action in the relatively new field of health literacy have been constrained by the emphasis on the literacy skills of the individuals. Early studies into the relationship between literacy and health outcomes were not appropriately balanced with examinations of individuals' skills and health system demands. Most studies focused on the measures of patients' reading skills without due attention to the health tasks undertaken, the health materials used, or the skills of providers with whom patients were interacting. Furthermore, public health is founded on the epidemiologic notion of the reciprocal relationship between individuals and environments. Early studies in health literacy did not attend to context-the physical and social environment of health-care settings. New initiatives in health literacy must bring attention to the demands and expectations of health systems and to the proficiencies of the various health professionals who prepare documents and information for the public and who interact with communities and patients.
