Introduction & definition
DALY = Disability Adjusted Life Year = the sum of years of potential life lost due to premature death, and the years of productive life lost due to disability.
The WHO website summarises the DALY thus:
"One DALY can be thought of as one lost year of 'healthy' life. The sum of these DALYs across the population, or the burden of disease, can be thought of as a measurement of the gap between the current health status and an ideal health situation where the entire population lives to an advanced age, free of disease and disability.
Calculation of DALY
This measurement is a combination of 2 measurements (shown below):
DALY = YLL + YLD
ie. Disability Adjusted Life Year [DALY] is equal to the sum of the Years of Life Lost [YLL] due to premature mortality in the population and the Years Lost due to Disability [YLD} for people living with the health condition.
YLL
YLL = Years of Life Lost
This consists of the number of deaths multiplied by the standard life expectancy at the age at which death occurs.
The formula for this is: YLL = N x L
N = number of deaths and L = standard life expectancy at age of death (in years)
YLD
YLD = Years Living with a Disability
