II. Office-based Simple Screening Tests to Extend Healthy Life Expectancy

The aging process and potential interventions to extend life expectancy

Aging is commonly defined as the accumulation of diverse deleterious changes occurring in cells and tissues with advancing age that are responsible for the increased risk of disease and death. The major theories of aging are all specific of a particular cause of aging, providing useful and important insights for the understanding of age-related physiological changes. However, a global view of t...

Methods for life expectancy and healthy life expectancy uncertainty analysis

Healthy Life Expectancy Is Expanding.

This is a very complex issue given that the issue involves many factors, including genetics, socioeconomic status, culture, and the quality and availability of healthcare services. Furthermore, it is not easy to define many of the above elements (e.g., culture, quality). Even if we could, determining the individual effects of components that we know can influence healthy life expectancy (HLE) (...

Global Patterns of Healthy Life Expectancy

Background: Healthy life expectancy – sometimes called health-adjusted life expectancy (HALE) – is a form of health expectancy indicator that extends measures of life expectancy to account for the distribution of health states in the population. The World Health Organization reports on healthy life expectancy for 192 WHO Member States. This paper describes variation in average levels of populat...

Healthy life expectancy in 191 countries, 1999.

We describe here the methods used to produce the first estimates of healthy life expectancy (DALE) for 191 countries in 1999. These were based on estimates of the incidence, prevalence, and disability distributions for 109 disease and injury causes by age group, sex, and region of the world, and an analysis of 60 representative health surveys across the world. We used Sullivan's method to compu...
