Burden of disease
a measure of the impact of diseases and injuries, specifically it measures the gap between current health status and an ideal situation where everyone lives to an old age free of disease and disability. It is measured in a unit called DALY
Disability-adjusted life year (DALY)
a measure of burden of disease. One DALY is equal to one year of healthy life lose due to illness and/or death. DALYs are calculated as the sum of the years of life lose due to premature death and the years lived with disability for people living with the health condition or its consequences
Life expectancy

Health-adjusted life expectancy (HALE)
average length of time an individual at a specific age can expect to live in full health; that is, time lived without the health consequences of disease or injury
Mortality

Self-assessed health status
An individuals own opinion about how they feel about their health, their state of mind and their life in general
