Health-Adjusted Life Expectancy (HALE) measures years weighted by health, unlike traditional life expectancy. Women and those in early old age experience a higher burden of ill health.

Area of Science:

  • Public Health
  • Health Economics
  • Biostatistics

Background:

  • The National Task Force on Health Information recommended an aggregate population health index in 1991.
  • Assessing population health requires indicators beyond traditional life expectancy.

Purpose of the Study:

  • To present Health-Adjusted Life Expectancy (HALE) as a population health indicator.
  • To compare HALE with traditional life expectancy to quantify the burden of ill health.

Main Methods:

  • Utilized the Health Utility Index to measure health status.
  • Employed 1994-95 National Population Health Survey data.
  • Calculated HALE by weighting years of life by health status.

Main Results:

Related Experiment Videos

  • The societal burden of ill health is greater for women than for men.
  • Ill health burden is highest in "early" old age, not the most elderly.
  • Sensory problems and pain are the largest components of the ill health burden.
  • Higher socioeconomic status is associated with longer life expectancy and lower ill health burden.

Conclusions:

  • HALE provides a more comprehensive measure of population health than traditional life expectancy.
  • Understanding the burden of ill health can inform public health interventions.
  • Socioeconomic factors significantly influence both lifespan and health status.
