Core 1 IQ2: What are the priority issues for improving Australia's health? Flashcards
What are some examples of the differences in the level of health of particular groups in our generally affluent society? (2)
These differences exist in terms of:
Unequal distribution of some illnesses or conditions throughout the population (across different demographics)
Health inequities; unjust impact on the health status of some groups due to social, economic, environmental and cultural factors such as income, education
What are the three (general) determinants of health?
Sociocultural determinants
Socioeconomic determinants
Environmental determinants
What is included in sociocultural determinants of health (5)?
Family
Peers
Media
Religion
Culture
What is included in socioeconomic determinants of health? (3)
Employment
Education
Income
What is included in the environmental determinants of health? (3)
Geographical location
Access to health services
Access to technology
What is the difference in life expectancy for ATSI people compared to non-ATSI peoples?
There is a difference of 10 years, and this has continued throughout the years leading up to 2023.
WHat is the trend in life expectancy for ATSI in prior years?
It has been increasing slowly.
What is Cardiovascular Disease (CVD)?
Refers to damage to, or disease of the heart, arteries, veins and/or smaller blood vessels.
Why has CVD been identified as a health priority area?
Because it is a major health and economic burden on Aus. It accounted for 42, 300 deaths (25% of all deaths) in 2019, according to AIHW
What subgroups are more susceptible to death from CVD?
Males are more likely than females to die from the disease, and ATSI people die from the disease at twice the rate of the total population
What is the nature of Cardiovascular disease?
It mainly affects the circulatory system. It has 3 major forms; coronary heart disease, stroke and peripheral vascular disease. It is most evident as stroke, heart attack, angina, heart failure and peripheral vascular disease.
Atherosclerosis is the underlying cause of most of these conditions
What is Atherosclerosis?
It is the build up of fatty and/or fibrous material on the interior walls of arteries. This build up hinders flow of blood to the body’s tissues and also acts to increase blood pressure.
Atherosclerosis can occur in any artery of the body, but it is of greatest threat to an individual’s health when it is present in the arteries lading to the brain, eyes or legs or the heart
Typically occurs in patches known as atheroma or plaque and is characterised by the presence of cholesterol
High blood pressure, smoking and a diet rich in fat can accelerate the development of atherosclerosis
What is the major function of the heart, and what happens when the individual has atherosclerosis in the coronary arteries?
Major function of the heart is to supply the body with oxygen rich blood. To perform continual intense exercise, the heart requires a supply of Oxygenated blood, which is received from the coronary arteries. The presence of atherosclerosis in the coronary arteries reduces the needed supply of blood, depriving the muscle of oxygen, and hindering the functioning of the heart
Wha is Arteriosclerosis?
The hardening of arteries, and it is a degenerative disease that occurs during ageing, and it is a form of atherosclerosis, as it develops as fatty or fibrous deposits build up and arteries become harder and less elastic
What is coronary heart disease?
Also known as ischaemic heart disease, it refers to damage or disease in the heart’s major blood vessels. The usual cause is the build-up of plaque. This causes coronary arteries to narrow, limiting blood flow to the heart. Typically manifests as a heart attack or angina
What is a heart attack known as? (3)
myocardial infarction, coronary thrombosis and coronary occlusion
What is a heart attack caused by?
The complete closure of a coronary artery by atherosclerosis, and can also occur hen blood clot forms and blocks a narrowed artery.
The efficient functioning of the heart relies on a regular oxygenated blood flow, so the cessation of the flow to any part of the heart results in tissue death.
What can a heart attack cause?
Sudden death or impaired function of the heart muscle, the area of damage may also be minimal and the individual can resume everyday activity. During the healing process following a heart attack, nearby arteries grow new branches to supply the damaged tissue
What are 5 symptoms associated with heart attacks?
Sudden collapse or unconsciousness
Shortness of breath, nausea, vomiting, excessive sweating
Chronic pain, lasting for hours or days
Acute pain, extending to the shoulders, neck, arms and jaw
Pain felt as a burning sensation in the centre of the chest, between the shoulder blades or behind the breast bone
What is an angina pectoris? (or angina)
Medical term used to describe the chest pain that occurs when the heart has an insufficient supply of oxygenated blood. Thus, it’s not really a disease but a symptom of oxygen deprivation
What is an angina caused by?
Generally caused by coronary atherosclerosis, where the narrowed arteries allow enough oxygenated blood to flow to the heart to enable everyday activity, but chest pain or tightness occurs when the heart becomes overloaded by exertion, excitement or overeating
What is a stroke?
A stroke refers to damage to the brain from interruption of its blood supply. It is known medically as a cerebrovascular accident
What is a stroke caused by?
Occurs when the blood supply to the brain is interrupted by a clot / atherosclerosis or when a burst blood vessel haemorrhages into the brain
What is a risk factor for a stroke, why?
Hypertension is a risk factor for a stroke, as blood vessels directly damaged due to high blood pressure tend to either rupture more easily or result in an aneurysm (which could lead to a rupture)
What are the symptoms of stroke?
Sudden confusion
Trouble speaking
Lack of coordination, dizziness
Difficulty walking
Paralysis on one side of the body
what is the acronym to identify stroke?
F - Face
A - Arms
S - Speech
T - Time
What is heart failure?
Heart failure occurs when the heart muscle doesn’t pump blood as well as it should. It is a reflection of the heart’s inability to cater for the demands placed on it during every day life. It doesn’t mean that the heart has stopped beating
Typically occurs because the heart is unable to compensate for; atherosclerosis, heart attacks, high blood pressure, defective heart valves, and more
A critical symptom is repeated breathlessness
What does left heart failure do?
Decreases blood flow, reduces exercise tolerance, weakness, confusion, increased pressure in lungs –> difficulty breathing, enlargement of heart to compensate for he problem
Typically caused by a heart attack
WHat does right heart failure cause?
Causes pressure to build up in the right atrium, so blood cant return to the heart from the body in the usual way, causes issues with the legs and thee liver
What is peripheral vascular disease?
Peripheral vascular disease is the reduced circulation of blood to a body part other than the brain or heart
What causes peripheral vascular disease?
Result of reduced blood flow to the legs and feet, usually due to atherosclerosis and/or arteriosclerosis. Given a slowed flow of blood to the leg muscles, walking results in a cramping feeling
9/10 of people with this are smokers
What are symptoms of peripheral vascular disease?
Tingling sensations in the feet and tightness (cramping in the legs and buttocks, particularly after exercise. It may lead to gangrene
What should be included when discussing the extent of cardiovascular disease in Aus?
Should discuss the mortality, morbidity and how many people it has affected, its trends
How many people over 18 years old have hade 1 or more conditions related to heart, stroke or vascular disease in 2017-18? (i.e. morbidity)
1.2 Million Australians - 6.2% of adult population (NEED TO CHECK THIS STAT)
What is the trend in CVD?
Over 35 years from 1980 to 2015, there has been a steady decline in CVD death rates. Death rates have fallen from 560 to 151 deaths peer 100 000 people
What % of deaths in Aus is caused by CVD? Whats the trend in CVD mortality?
Cause 27% of deaths in Aus in 2021. Death rates from CVD has declined considerably over recent decades, showing signs of continuing to fall.
What is the general mortality trend for CVD
Declining overall, however th decline in younger age groups have slowed relative to improvements made in older age groups
What is the cause of the declining prevalence of CVD? (2)
Reduction in the levels of risk factors; implementation of prevention strategies have led to a reduction in smoking levels, increased monitoring of hypertension levels and diet modifactions
Improved medical care and treatment; which have ultimately led to reduced mortality and improved quality of life
What are the risk factors for CVD which CANT be changed? (3)
Risk factors increasing the chance of CVD and mortality from CVD include:
A family history of heart disease. People with family history of heart disease are more likely to develop CVD
Gender. The cardiovascular disease death in men aged up to 50 years is higher than in women. This is largely due to hormones, as oestrogen is thought to be a protective factor for CVD
Advancing age; The risk of CVD increases with age
What are 4 risk factors for CVD which can be changed?
Smoking; The risk of heart attack and stroke is doubled by heavy smoking, risk of sudden cardiac death is also higher.
Raise blood fat levels; the higher the blood cholesterol levels, the higher risk of heart disease. A diet high in fat can raise cholesterol levels
High blood pressure; The risk of heart disease, stroke and heart failure all increase with hypertension. It can overload the heart and blood vessels and speed up atherosclerosis
Physical inactivity; the association of inactivity with obesity, high blood pressure and high fat levels makes it a significant contributor to the development of heart disease
What are 5 protective factors, reducing the chance of developing CVD?
Regular physical activity
Maintaining healthy eight
Avoiding exposure to tobacco and tobacco smoke
Consuming a diet low in salt
Lo consumption of alcohol
What should we discuss when talking about the determinants of CVD?
Should discuss sociocultural, socioeconomic and environmental determinants
What are the sociocultural determinants of CVD? (4)
People with a family history of CVD are more at risk
Asians are less prone to getting CVD due to a generally low-fat diet
ATSI people more at risk as they are associated with have lower socioeconomic status and lower edu levels
Media exposure (Cultural factor) to the effects of smoking on health have lead to a reduction in smoking rates and a declining trend in CVD
What are the socioeconomic determinants of CVD? (2)
People with a low socioeconomic status or who are unemployed have higher death rates because income can limit health choices, such as purchasing fresh fruit and vegetables and using exercise facilities.
People with low education levels are more at risk as poor education is linked to poor health choices and less knowledge about how to access and use health services.
What are the environmental determinants of CVD? (1)
People living in rural and remote areas are more at risk as thy tend to have less access to health info, health services and tech, such as electrocardiogram monitors
What 7 groups are at risk of developing CVD?
Tobacco smokers
People with family history of CVD
People with high fat diets
People with high blood pressure
Males
People aged over 65 years
Blue-collar workers (labourers and tradespeople) - may have higher levels of smoking, alcohol consumption and high fat diets
Is the prevalence of stroke (i.e. a cardiovascular event) higher in men or women? STats
1.6% in males
1.1% in females
Which age groups does CVD affect the most?
65+ have had 71% of people having a stroke
WHat % does stroke conttribute to hospitalisations from CVD?
11% of CVD hospitalisations and 0.6% of total hospitalisations
How many new cases of canceer were there in 2022?
About 162, 200 new cases of cancer were diagnosed in Aus
Why has there been an increasing trend to 2008 in cancers?
Largely due to a rise in the number of diagnosed prostate cancer in males and breast canceer in females. This trend may have been the result of increased prostate specific antigen testing and the introduction of national cancer screening programs
What should you discuss when talking abut the nature of a preventable chronic disease?
What is it?
What are the different forms of this disease?
Potential causes of this disease
What is cancer?
Refers to a diverse group of several hundred diseases with a common feature - the uncontrolled growth and spread of abnormal body cells. It involves a mutation and is believed to originate from a single cell whose genetic material has been influenced or damaged by some foreign agent.
The changed cell divides and multiplies uncontrollably, transferring its damaged genetic material to its offspring cells. Eventually, a tumour develops and cells that would normally work together for the benefit of the tissue continue to multiply independently, starving other nearby cells of nourishment. This group of cells is now referred to as a neoplasm.
What are the two different types of tumours?
Benign tumours
Malignant tumours
What are benign tumours?
These aren’t cancerous. They generally grow slowly, surrounded by a capsule that leads to control their spread. Usually the cure is surgical removal. They may cause some damage by robbing surrounding tissue of necessary nutrients or interfering with the function of vital organs, but generally aren’t too harmful
What are malignant tumours?
These are cancerous. Without the restraint of a controlled capsule, they can spread to other parts of thee body, starve surrounding tissue of necessary nutrients and invade healthy tissue. These can cause sickness and death
What are metastases?
These are secondary or new tumours. They may develop some distance from the original malignant tumour, because the malignant tumour has the ability to invade surrounding tissues, blood vessels and lymphatic channels, spreading into either the bloodstream or lymph fluid, and travelling to the other parts of the body
Both metastases and malignant tumours are capable of spreading to many sites throughout the body, affecting the whole body with the disease
What are Carcionogeens?
These are agents that are known to cause cancer. However, the precise causes of cancer is a mystery.
What do carcinogens include?
Chemicals, pollution, radiation, cigarette smoke, dietary factors and alcohol
What are 4 different classifications of cancer and their sites?
Carcinoma; Skin; membranes lining the respiratory, gastrointestinal and urinary tracts; the breasts
Sarcoma; bones, cartilage, muscles
Leukaemia; blood forming organs such as bones the liver and the spleen
Lymphoma; infection fighting organs (glands and the spleen)
Is cancer the leading cause of death in Aus?
YES it is the OVERALL leading cause of death (as it encompasses breast, prostate, lung and more different cancers which contribute to a high mortality rate)
What are the risk factors for lung cancer? (3)
Tobacco smoking
Occupational exposure to carcinogns such as asbestos
Air pollution
What are the risk factors for breast cancer? (5)
A family/personal history of the disease
Obesity
Early onset of menstruation
A high fat diet
Late menopause
What are the risk factors for skin cancer? (5)
A fair skin that burns rather than tans
High number of hours of bright sunlight at place of residence
Prolonged exposure to the sun, especially as a child and adolescent
Number and type of moles on the skin
Fair or red hair and blue eyes, combined with residence in high sun exposure areas
What are the leading risk factors causing the highest mortality rates from cancer? (5)
Tobacco - 30% of all deaths from cancer
Diet - 10-70%
Sexual reproductive patterns - 7%
Occupational factors - 4%
Alcohol factors - 4%
What are the protective factors for lung cancer? (2)
Avoid exposure to tobacco smoke
Avoid exposure to hazardous materials such as asbestos
What are the protective factors for breast cancer? (3)
Consume a high diet in fruits and vegetables, and low in fat
Have regular mammograms if over the age of 50 years old (government allows for free mammograms for any woman over the age of 50yo, looking to get screened for breast cancer)
Practise self examination (i.e. paying attention to own body and if something feels off)
What are the protective factors for skin cancer? (2)
Avoid excess exposure to strong sunlight
Reduce exposure to the sun by wearing a hat, sunscreen, protective clothing and sunglasses
Which groups are at the highest risks of developing lung cancer? (4)
Cigarette smokers
People exposed to occupational or environmental hazards such as asbestos
People working in blue collar occupations (labourers / manual work)
Men and women aged over 50 years old
Which groups are at the highest risks of developing breast cancer? (6)
Women aged over 50 years old
Women who have late menopause
Women who start menstruating at an early age
Obese women
Women who have never given birth
Women who have a direct relative with breast cancer (i.e. mother or sister)
Which groups are at the highest risks of developing skin cancer (4)
People with fair skin
People in outdoor occupations
People who spend too much time in the sun without protection such as hats and sunscreen
People in lower latitudes (UV intensity is greater at lower latitudes)
What are the environmental determinants for cancer?
People living in rural and remote areas are more at risk, as they tend to have less access to health information, health services such as Pap smears, and technology, such as breast screening devices.
What are the socioeconomic determinants for cancer? (4)
People in occupations involving repeated exposure to carcinogens, such as asbestos, are more at risk of lung cancer.
People working outdoors, such as lifeguards, are more prone to getting skin cancer.
Those with a low socioeconomic status or who are unemployed have higher death rates as income can limit health choices, such as purchasing fresh fruit and vegetables and using exercise facilities.
People with low education levels are more at risk as poor education is linked to poor health choices and less knowledge about how to access and use health services.
What are the sociocultural determinants for cancer? (3)
People with a family history of cancer
Incidence of lung cancer and cervical cancer higher in ATSI peoples as they tend to have hihger smoking levels and less access to health services
If your family practises health-promoting behaviours, such as adopting healthy eating habits, the risk of cancer is reduced.
What is the trend in incidence of cancer?
It is the only major cause of death in Aus which has been increasing in incidence for both sexes. The most significant increases in the past two decades have been for breast cancer, skin cancer and melanoma (malignant skin cancer), as well as prostate cancer
Increasing from 383/100 000 to 503/ 100, 000
