an individual or populations overall health, taking into account various aspects such as life expectancy, amount of disability and level of diease risk factors
self assessed health status
a measure of a persons overall health which reflects a persons perception of his or her own health at a given point in time
life expectancy
the number of years of life, on average, remaining to an individual at a particular age if death rates do not change.
HALE health adjusted life expenctancy
a measurement that considers life expectancy data and the impacts of ill health in a population
mortality
refers to the number of death in a population in a given period (usually 12 months)
maternal mortality
the number of mothers who die as a result of pregnancy or child birth , per 100 000 live births

the number or rate of new cases of a condition during a specified time, usually a 12 month period
prevalence
the number or proportion of cases of a particular disease or condition present in a population at a given time (total)
burden of disease
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 DALYs
disability adjusted life years (DALYs)
one DALY equals one year of health life lost due to premature death and time lived with illness, disease or injury
YLL
each YLL represents one year of life lost due to premature death
YLD
YLD is a measure of how many years of life are lost due to disease, injury or disability.
when measuring the relationship in data
“as _______ increases _________ decreases”
U5MR
the probability of a child born in a specific year or period dying before they reach the age of 5
