What does DALY stand for in health statistics?

DALY stands for Disability Adjusted Life Years, which is a key measure used in public health to assess the overall burden of disease. This metric combines years of life lost due to premature mortality and years lived with disability into a single, comprehensive number. It provides a way to compare the impact of different health issues on population health and allows for the evaluation of health interventions and strategies.

The importance of DALY lies in its capacity to quantify not just how many years individuals live, but the quality of those years. By incorporating disability into the equation, DALYs offer a more nuanced understanding of health outcomes, particularly for chronic diseases and conditions that may not lead to death but significantly impact an individual's quality of life.
