understanding health status indicators

• Examining these health status indicators allows governments  identify trends in levels of health and then target specific groups to work towards achieving optimal health & wellbeing 

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’ 

 

Life expectancy in Australia of someone born between 2019-2021 

• A male can expect to live to 81.3 years 

• A female can expect to live to 85.4 years 

mortality

number of deaths during a given period

mortality rate

proportion of a population who die in one year period

• help identify leading cause

• Help provide feed back on the success of curent inventions( policies , capaing , strateies ) reduce health condition

morbidity

level of ill health in populaition or individual

burdern of diease

measure of the impact of diseases and injuries of a popultation

Disability Adjusted Life Year

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; 

yll

• Years of Life Lost (YLL) 

• A measure of how many years of expected life are lost due to premature death. It is the fatal component of burden of disease 

• Years lost due to disability (YLD) 

• A measure of how many healthy years of life are lost due to living with illness, injury or disability. It is the non-fatal component of burden of disease  

calculating daly

A woman is diagnosed with cancer at age 45 and then dies from the cancer at age 55. Her life expectancy is 85 yrs. 

YLD = 55 – 45 

        = 10 (ten years ‘lost’ due to disability…so due to living with the cancer) 

YLL = expected life expectancy – age at death 

    = 85 – 55 

    = 30  

TOTAL DALY (total burden/impact of disease) = 10 (YLD) + 30 (YLL) = 40 DALYs
