YLD Calculation
- Measures years lived with disability due to disease or injury.
- Formula:
- Incidence-based: YLDi=I×DW×L
- Prevalence-based: YLDp=P×DW
- Disability Weights (DW):** Ranges from 0 (full health) to 1 (death), representing severity.
- Challenges in Estimation:
- Variability in experiences of the same condition.
- Standardizing disability weights across diverse diseases.
