First, the advantages and disadvantages of various methods of calculating the duration of life lost due to a death at each age are discussed. DALYs use a standard expected-life lost based on model life-table West Level 26. Second, the value of time lived at different ages is captured in ...
The Cohort Disability Adjusted Life Years (C-DALYs) differs from the Disability measurement in the specification of the discount function. Namely, the discount formula e-r(x-a) (where x = age, a = onset of disease year, and r=discount rate),is replaced by e-rx. Cohort Disability Adjuste...
Smoking-attributable deaths and years of potential life lost were estimated using the formula adopted to estimate UK and US deaths caused by smoking. These estimates are based on sex-specific proportions by age of current and ex-smokers and rates of relative risk. For prevalence data we used da...
