Which indicator best reflects the overall burden of chronic disease?

• A. Life expectancy
• B. Infant mortality rate
• C. DALYs
• D. Hospital bed occupancy

Answer: (C)

Capturing the total health loss from chronic disease requires a metric that includes both deaths and the time people live with illness. DALYs do this by combining years of life lost due to premature mortality with years lived with disability. This means they reflect not only how many people die early from chronic conditions but also how much of life is spent in ill health because of those conditions. Life expectancy looks mainly at overall survival and doesn’t account for quality of life or disability; infant mortality focuses only on deaths in infancy, missing the broader chronic-disease burden; hospital bed occupancy shows health-system use rather than the population’s total health loss. So, DALYs best represent the overall burden of chronic disease because they integrate fatal and non-fatal health outcomes into one measure.
