changes in life expectancy over time
Life Expectancy
Life expectancy data over time shows that significant improvements in health status have been made, with males expected to live 81.2 years in 2022 compared to 53.8 years in 1900. Similarly, females in 2022 had a life expectancy of 85.4 years compared to 57.5 years in 1900.
mortality over time
Life expectancy has increased however there have been changes to the leading causes of mortality since 1900.
The diseases that were common in Australia during the first half of the twentieth century are in many ways different from those that Australians face now.
Diseases can be grouped into five broad categories and account for 60% of deaths around 19000 and no 83% in the early 2000s.
what is public halth
Public health relates to the actions of governments to promote health and wellbeing and prevent the spread of disease. Eg. cholera, diarrhoea, measles.
what is old public health
Government that focuses on changing the physical environment to prevent the spread of diseases.
These actions contributed to a reduction in deaths from communicable diseases such as Cholera and Diarrhoea. As these were responsible for child mortality.
8 examples of action that were undertaken to improve health
- Providing safe water, sanitation and sewage disposal
- Improved nutrition
- Improved housing
- Better work conditions
- Masses immunisation programs
- More hygienic birthing practices
- Provision of antenatal and infant welfare services
- Introduction of quarantine laws
defining features of the biomedical model
- relatively expensive as medical professionals are central to the biomedical model and medical technology is also important in this model
- It focuses on the disease itself and not the factors that contribute to disease and therefore does not specifically target disease prevention
- It is responsible for many developments in medical technology and knowledge and is therefore a key reason for life expectancy increasing significantly over the past 100 years.
- It focuses on individuals with disease not the whole population
- It accounts for a large proportion of the health budget
3 strengths and weaknesses of the biomedical model of health 4
- Created advances in technology and research to diagnose and treat health conditions. (pathology tests, x rays, MRI, CAT scan) but relies of professional health workers and tech so is costly
- Many common health conditions can be effectively cured and treated but doesnt always promote good health
- Extends life expectancy by intervening in health conditions that often results in early mortality but not every condition can be treated
- Improves quality of life for people living with a health condition by decreasing the impact of the condition such as managing symptoms or pain with medication and other treatments. but it represents a big cost to the government
what is new public health
An approach to health that expands the traditional focus on individual behaviour to one that considers the ways in which physical, sociocultural and political environments impact on health, also referred to as the social model of health.
what is the social model of health
An approach that recognises improvements in health and wellbeing can only be achieved by directing effort towards addressing the physical, sociocultural and political environments of health that have an impact on individual and population groups.
It was developed in response to many lifestyle diseases increasing and some population groups not experiencing the same improvements in health and wellbeing as the rest of the population.
As a result, ‘new public health’ was developed to focus on the broader factors that influence health and wellbeing; the sociocultural and environmental factors that have a significant impact on health status.
examples of changes due to the social model of health
- Creating laws that promote health and wellbeing such as -smoking bans and road safety laws.
- Education campaigns such as the TAC TV ads, sunsmart.
- Empowering people by providing information about health foods through the health star rating system and educating people how to read food labels.
defining features of the social model of health
Can improve health status of disadvantaged groups
Can prevent diseases from occurring in the first place
Focuses on the broader determinants of health
Focusesses on communities and groups rather than individuals
Relatively inexpensive
strengths and weaknesses of the social model of health 4
- It promotes good health and wellbeing and assists in preventing diseases but not every condition can be prevented
- It promotes overall health and wellbeing but it does not promtoe the development of technology and medical knowledge
- It is less expensive than the biomedical approach bit it does not address health concerns of the individual
- Education can be passed on from generation to generation but health promotion messages may be ignored.
5 principles of the social model
- Intersectoral Collaboration
- Addresses the broader determinants of health
- Empowers individual communities
- Acts to increase access to health care
- Acts to reduce social inequalities
intersectoral collaboration
Intersectoral Collaboration
The greatest gains in health will be made if many sectors work together. Sectors such as the health sector, education sector, government and non government organisations, and the private sector should all work together. This will produce the greatest results.
Example: Road safety, TAC works with schools, community groups, sporting organisations and the health sector to promote the road safety message.
Addresses the broader determinants of health
Addresses the broader determinants of health
Factors such as education, income, occupation, housing, access to healthcare and cultural barriers play a significant role in health outcomes and must be addressed to produce optimal health and wellbeing.
Example: indigenous health campaigns.
