3.1.2 Flashcards
Health Status
an individuals or a populations overall health, taking into account various aspects such as life expectancy, amount of disability and levels of disease risk factors
Life expectancy
an indication of how long a person can expect to 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
HALE = ?
life expectancy – number of years living in unhealthy states
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.
BOD is measured in a unit called a Disability Adjusted Life Year (DALY)
Disability Adjusted Life Year (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 = ?
YLL + YLD
YLL
Years of life lost due to premature DEATH
fatal component of burden of disease
YLD
Years of healthy life lost due to living with a disability (non-fatal component of burden of disease)
Disability weights
a scale ranging from 0-1 that reflects the severity of a range of conditions
calculation of YLD
number of years a person suffers from a condition multiplied by the disability weight
Mortality
Refers to deaths caused by a particular disease, illness or other environmental factor
Under-five mortality rate (U5MR)
Measures the number of children that die before their fifth birthday (usually given per 1000 live births)
Infant mortality rate (IMR)
Measures the number of deaths of infants between birth and their first birthday (usually given per 1000 live births)
Maternal mortality rate (MMR)
The number of deaths of females who are either pregnant or in the first 42 days after giving birth or having a termination (usually given per 100,000 live births)
