DALY: Disability-adjusted life years A DALY refers to the loss of one year of full health in a person’s life due to injury, disease, or disability. It is a measure used to quantify the burden of disease and to compare the overall health and life expectancy of different populations. DALY = YLL + YLD |
YLL: Years of life lost to premature death YLLs are calculated by multiplying the number of deaths by a global standard life expectancy at the age of death. It is a measure of premature mortality that takes into account both the frequency of deaths and the age at which it occurs |
YLD: Years of life lived with disability Each YLD represents one full year of healthy life lost due to illness or disability |
Incidence Rate It is the proportion of new cases within a specific time period to the total number of people at risk for the disease. The total observation time of the population within a given calendar year refers to the approximate number of people in the population at the beginning of the year |
Mortality Rate: Deaths in the population It is the number of deaths from a disease divided by the total population. The total observation time of the population within a given calendar year refers to the approximate number of people in the population at the beginning of the year |
