Reevaluating health metrics: Unraveling the limitations of disability-adjusted life years as an indicator in disease burden assessment

Table 1 Comparison of age profiles of death and disease durations with identical disability-adjusted life years values

Age of death	Number of sick years	YLL	YLD	DALY
54	0	90-54 = 36	0 × 0.4 = 0	36 + 0 = 36
56	5	90–56 = 34	5 × 0.4 = 2	34 + 2 = 36
58	10	90–58 = 32	10 × 0.4 = 4	32 + 4 = 36
62	20	90–62 = 28	20 × 0.4 = 8	28 + 8 = 36
70	40	90–70 = 20	40 × 0.4 = 16	20 + 16 = 36
90	90	90–90 = 0	90 × 0.4 = 36	0 + 36 = 36

DALY: Disability-adjusted life years; YLL: Years of life lost; YLD: Years lost due to disability.
