health status Flashcards
(21 cards)
health status
An individual’s or a population’s overall 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
trend
a general movement or pattern in the data
relationship
the connection between the two concepts
self assessed health status
An individual’s own opinion about how they feel about their health, their state of mind and their life in general.
life expectancy
an indication of how long a person can expect to live. The number of years of life remaining to an individual at a particular age if death rates do not change.
health adjusted life expectancy (HALE)
a measure of burden of disease based on life expectancy at birth, but including an adjustment for time spent in poor health.
mortality
Refers to deaths in a population in a given period.
mortality rate
Number of deaths in a 12 month period per 1000 or 100,000 people from a specific cause.
infant mortality rate
the rate of deaths of infants before their first birthday, usually expressed per 1000 live births
under 5 mortality rate
the number of deaths of children under five years of age per 1000 live births
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, childbirth or associated treatment per 100 000 women who give birth (or per 100 000 live births)
morbidity
ill health in an individual and the levels of ill-health in a population
prevalence
The number or proportion of cases of a particular disease or condition present in a population at a given time.
incidence
The number of new cases of a condition during a given period of time.
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
DALY
A measure of burden of disease, one DALY equals one year of healthy life lost due to premature death, illness, disease or injury. DALY =YLL+YLD
Years of life lost (YLL)
a measure of how many years of expected life are lost due to premature death
Years lived with disability (YLD)
a measure of how many healthy years of life are lost due to illness, injury or disability
