Chapter 3 - Factors Influencing Health Status and Burden of Disease Flashcards
(38 cards)
The Four Influential Factors on Health Status of Australians
- Smoking
- Alcohol
- High body mass index
- Dietary risks
What is smoking?
Smoking is a practice in which a substance is burned and the resulting smoke is inhaled and absorbed into the bloodstream.
What does the impact of tobacco include?
The impact of tobacco includes the risks associated with past tobacco use, current use, and exposure to second hand smoke.
What Is Alcohol Use Disorder and What May Indicate the Presence of This?
Alcohol misuse over a period of time can indicate the presence of an alcohol use disorder - a disease characterised by ongoing risky alcohol consumption.
Alcoholism
Alcoholism is when a person can’t stop drinking once they have started, or has a constant desire to drink alcohol.
Binge Drinking
Binge drinking in Australia is defined as consuming more than four standard drinks in one sitting.
Health Concerns due to Smoking
- Cardiovascular disease
- Cancer
- Asthma
- Prenatal and infancy health concerns
- Respiratory conditions
- Infections
Burden of Disease due to Smoking
- Responsible for just under 20% of burden of disease for coronary heart disease and 10% for asthma.
- Responsible for almost 80% of lung cancer DALYs and 72% Chronic Obstructive Pulmonary Disease (COPD) DALYs.
- Low birth weight is a leading cause of burden of disease in 0-14 year olds.
Health Status due to Smoking
- Increased morbidity and mortality from cardiovascular disease (CVD), cancer and chronic obstructive pulmonary disease (COPD).
- Increased risk of infection due to low birth weight contributing to increased infant and under-5 mortality rates.
- Increased morbidity from asthma attacks and infectious diseases such as upper respiratory tract infections.
- Lower life expectancy and health adjusted life expectancy.
Health Concerns due to Alcohol
- Alcohol use disorder
- Weight gain, high body mass index and associated conditions including cardiovascular disease, some cancers and type 2 diabetes.
- Cancer (including mouth, throat, stomach, bowel, liver and breast)
- Liver disease (including cirrhosis)
- Injuries
- Mental health issues and self-harm
- Prenetal/infant health outcomes (including premature birth, low birth weight and foetal alcohol spectrum disorder (FASD).
Burden of Disease due to Alcohol
- Responsible for all DALY associated with alcohol use disorders
- 24% of total burden due to traffic injuries was due to alcohol use
- Caused 28% of total DALY due to liver diseases
- Contributed 14% of DALY due to suicide and self-inflicted injuries.
- Increases YLL and YLD due to cardiovascular disease.
Health Status due to Alcohol
- Increased incidence and mortality from cardiovascular disease, type 2 diabetes, some cancers, liver diseases, injuries.
- Higher rates of morbidity due to mental health issues.
- Increased infant and under-5 mortality rates.
Alcohol misuse
Relates to the excessive consumption of alcohol and includes alcoholism and binge drinking.
Body Mass
Relates to the amount of body weight an individual is carrying. Generally, assessments about body mass are made using the body mass index (BMI) and waist circumference measurements.
Body Mass Index (BMI)
A statistical measure of body mass calculated by dividing weight (in kg) by height (in m^2). BMI does not take fat distribution into account.
E.g. For someone who is 182 cm tall and weights 88 kg:
BMI = 88/1.82^2
= 88/3.31
= 26.6
Health Concerns due to high BMI
- Cardiovascular disease
- Some cancers
- Type 2 diabetes
- Kidney disease
- Osteoarthritis and osteoporosis
- Asthma
- Mental health issues
- Maternal health conditions
Burden of Disease due to high BMI
- Contributes to 54% of diabetes burden.
- Caused 40% of kidney disease burden.
- Contributes to 25% of coronary heart disease burden and 21% of stroke burden.
- YLD for mental health issues, osteoarthritis, type 2 diabetes and asthma.
Health Status due to high BMI
- Increased morbidity and mortality rates due to a range of causes such as cancer, cardiovascular disease and kidney disease.
- Lower life expectancy and HALE.
Health Concerns due to Underconsumption of Vegetables
- High body mass index and associated conditions
- Various cancers
- Cardiovascular disease
- Neural tube defects (conditions characterised by damage to the brain and spine, and to the nerve tissue of the spinal cord during prenatal development. E.g. spina bifida, anencephaly)
Nutrient Dense
Foods that contain a large amount of nutrients such as vitamins and minerals.
Antioxidants
Compounds in food that neutralise free radicals.
Free radicals are molecules that can damage body cells and increase the risk of conditions such as cardiovascular disease and cancer.
Vegetables
Vegetables are nutrient dense. They are high in minerals and vitamins, low in kilojoules and high in dietary fibre and antioxidants. Eating a range of them increases the variety and amount of vitamins and minerals consumed. Many of these nutrients promote adequate functioning of body systems, including immune system functioning, which can reduce the incidents of conditions such as cancer, cardiovascular disease, etc.
Health Concerns due to Underconsumption of Fruit
- High body mass index and associated conditions
- Various cancers
- Cardiovascular disease
- Neural tube defects
Fruit
- Provides a range of essential nutrients such as vitamins, minerals and fibre, while being low in fat and a good source of antioxidants.
- Reduces risk of conditions such as CVD, cancers and neural tube defects since it promotes adequate functioning of body systems.
- People who eat adequate amounts of fruit are likely to feel full for longer and are therefore less likely to consume energy dense foods.
