When disability-adjusted life years (DALYs) were first formulated, the effect of age-weighting on years of life lost due to death at each age as well as the different effect on short- and medium-term disability were taken into consideration. While there is considerable scope for discussion on the actual values that are incorporated into DALYs, the present article argues that once the values have been chosen we should accept the consequences of the choice.
当首次制定伤残调整生命年（DALYs）时，就考虑到了年龄加权对各年龄段因死亡而损失的生命年的影响，以及对短期和中期残疾的不同影响。虽然对于纳入DALYs的实际数值有相当大的讨论空间，但本文认为，一旦选定了这些数值，我们就应该接受该选择带来的后果。
