Health Status Indicators Flashcards
Health Status
An individuals or populations overall level of health and wellbeing, taking into account various aspects such as life expectancy, amount of disability and levels of disease risk factors.
Self-assessed Health Status
A measure based on a persons own opinion about how they feel about their health and wellbeing, their state of mind and their life in general. Commonly sourced from population surveys.
Life Expectancy
An indication of how long a person can 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)
A measure of burden of disease based on life expectancy at birth, but including an adjustment for time spent in poor health. 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.
Burden of Disease
A measure of the impact of disease 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. (Measured in DALY’s).
Disability Adjusted Life Years (DALY)
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.
DALY’s are calculated by adding YLL’s and YLD’s.
Years of Life Lost (YLL)
Years of life lost from premature death.
Years Lost due to Disability (YLD)
A measure of how many healthy years have been lost by living with disease, injury or disability.
Mortality
Relating to death, often at a population level.
Mortality Rate
The measure of the proportion of a population who die in a one-year period (per 100,000 people).
Maternal Mortality
Death of a mother during pregnancy, childbirth or within 6 weeks of delivery occurring as a result of the pregnancy, birth or related treatments.
Maternal Mortality Rate (or Ratio)
The number of mothers who die as a result of pregnancy or childbirth (per 100,000 live births).
Infant Mortality
Refers to deaths occurring between birth and first birthday.
Infant Mortality Rate
The rate of deaths of infants between birth an their first birthday (per 1000 live births).
Under 5 Mortality
Refers to deaths occurring between birth and their fifth birthday.
