A long and yet unfinished history of investigating how individual capabilities and social processes explain or predict health indicates that poor education, low literacy, poor health and early death are strongly linked around the world. However, the complexity of those relationships is not fully understood. In this article, we propose an expanded model of health literacy characterized by four domains: fundamental literacy (reading, writing, speaking and numeracy), science literacy, civic literacy and cultural literacy. To explore the utility of this model, we examine selected pieces of the public discourse about terrorism and bioterrorism that dominated the mass media during the anthrax threat in the United States during 2001. We conclude that this model of health literacy is useful to analyze health communication, to aid in constructing more understandable and appropriate health communication, and ultimately can lead to the development of a new measure to assess health literacy skills in individuals.
This study was designed to demonstrate the feasibility of forecasting functional health for the elderly. Using life-table techniques, we analyzed the expected remaining years of functional well-being, in terms of the activities of daily living, for noninstitutionalized elderly people living in Massachusetts in 1974. The expected years, or active life expectancy, showed a decrease, from 10 years for those aged 65 to 70 years to 2.9 for those 85 or older. Active life expectancy was shorter for the poor than for others, and women had a longer average duration of expected dependence than men. The measure of active life expectancy provides important information about health at a given population level, in terms other than death. This information can be used for actuarial purposes in planning and policy making. It is also useful in identifying high-risk populations for which preventive health care and medical care can compress morbidity during the last years of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
