YLD Calculation

• Measures years lived with disability due to disease or injury.
• Formula:
  • Incidence-based: $YLD_i = I \times DW \times L$
  • Prevalence-based: $YLD_p = P \times DW$
• 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.
