An epidemiologist wants an indicator that combines life expectancy with the expected years lived without disability for a population. Which of the following measures serves this purpose?
- A Sullivan's index ✓
- B Human Development Index
- C Physical Quality of Life Index
- D Standardized death rate
Correct answer: A. Sullivan's index
Explanation
Sullivan's index, or disability-free life expectancy, subtracts the expected duration of disability from total life expectancy, yielding the average number of years a person can expect to live free of disability. It combines mortality and morbidity into one summary measure. The Human Development Index combines income, education and life expectancy but ignores disability, and the Physical Quality of Life Index uses literacy, infant mortality and life expectancy at age one. Standardized death rates adjust only for age structure.
