Chapter 2 Flashcards
Health Status
An individual’s or a population’s overall level of health, taking into account various aspects such as life expectancy, amount of disability and levels of disease risk factors.
Health Indicators
Standard Statistics that are used to measure and compare health status (e.g. life expectancy, morbidity and mortality rates)
Incidence
The number of new cases of a condition during a given period of time, usually 12 months.
Prevalence
The total number or proportion of cases of a particular disease or condition present in a population at a given time.
Morbidity
Refers to ill-health in an individual and the levels of ill-health in a population or group.
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. Burden of disease is measured in a unit called the DALY.
Disability Adjusted Life Years (DALYS)
A measure of burden of disease, one DALY equals one year of healthy life lost due to premature death and time lived with illness, disease or injury.
years of life lost (YLL)
a measure of how many years of expected life are lost due to premature death
years lost due to disability (YLD)
a measure of how many healthy years of life are lost due to illness, injury or disability
Life expectancy
An indication of how long a person can expect live, it is the number of years of life remaining to a person at a particular age if death rates do not change.
Health Adjusted Life Expectancy
(HALE)
It is the number of years in full health that a person can expect to live, based on current rates of ill health and mortality. It is an indicator of quantity and quality of life.
Mortality
Refers to death, often at a population level.
Maternal mortality
Death of a mother during pregnancy, childbirth or within six weeks of delivery.
Maternal mortality ratio
The number of mothers who die as a result of pregnancy or childbirth per 100 000 live births.
Infant mortality
The death of a child between birth and their first birthday.
