What is the definition of disability-adjusted life year (DALY)? (YLL+YLD)
One DALY equals one year of healthy life lost due to premature death and time lived with illness, disease, or injury.
What is the definition of years of Life lost (YLL)?
Each YLL represents one year of life lost due to premature death.
What is the definition of years lived with disability (YLD)?
Measure of how many years of life are lost due to disease, injury, disability.
What is the definition of life expectancy?
The number of years of life, on average, remaining to an individual at a particular age if death rates do not change.
What is the definition of health-adjusted life expectancy (HALE)?
A measurement that considers life expectancy data and the impact of ill heath in a population.
What is the definition of mortality?
Refers to a number of deaths in a population in a given period (usually 12 months).
What is the definition of maternal mortality rate?
Number of mothers who die as a result of pregnancy or childbirth per 100,000 live births.
