Years Lived with Disability (YLD) is a measure used in public health to quantify the impact of living with a disability. It represents the number of years a person lives with a health condition that affects their daily activities or quality of life. YLD is often used in conjunction with other metrics, such as Disability-Adjusted Life Years (DALY), to assess the overall burden of diseases and disabilities in a population. YLD helps policymakers and health organizations understand the prevalence and severity of disabilities. By analyzing YLD data, they can allocate resources more effectively and develop targeted interventions to improve the quality of life for individuals with disabilities.
