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.
