CHAPTER TWO: exploring differences in health status Flashcards
leading causes of death in Australia
- cardiovascular disease - coronary heart disease (heart attack and related disorders) and cerebrovascular disease (mainly in the form of stroke)
- dementia (alzheimer’s)
- lung cancer
- chronic obstructive pulmonary disease (COPD)
causes of mortality by age
- chronic conditions are the prominent cause of death among people aged 45 and over
- external causes such as accidents, suicide and poisoning are more prominent causes of death for younger people (15-44 years)
chronic conditions
- non communicable
- highest contributors to morbidity and burden of disease in australia
- includes cardiovascular disease, COPD, cancer, diabetes mellitus, asthma, osteoarthritis, back problems, mental and behavioural problems
disability
- blanket term to describe impairments, activity limitations and participation restrictions
biological factors
- relating to the body that impact on health and wellbeing and thus overall levels of health status, including genetics, body weight, blood pressure, cholesterol levels, blood glucose levels, age and birthweight
genetics
biological factor
- plays a role in determining lifespan health and wellbeing and the likelihood of developing specific diseases
- predisposition to disease: influence an individual’s risk of getting some diseases, but it does not mean that an individual will develop this condition
- other related conditions are caused by the inheritance of DNA variants, referred to as mutations, which result in a change in one of the genes affecting the way the body works or develops
body weight
biological factor
- particular concern to Australia’s health status is the incidence of overweight and obesity
- overweight and obese individuals are at higher risk of cardiovascular disease, some types of cancer, arthritis, type 2 diabetes mellitus
- body weight is influenced by genetics as well as body function in relation to metabolism and hormonal control
blood cholesterol
biological factor
- waxy, fatty substance found in all cells of the body
- used by the body for the production of hormones, vitamin D and digestive enzymes
blood pressure
biological factor
- measurement of pressure of the blood in the artery
- rises and falls during the day and is influenced by a number of factors; for example, body position, exercise, sleep and emotional state
- hypertension: heart is working too hard, increasing the risk of heart failure
- hypertension can result in other conditions: congestive heart failure, kidney disease and blindness
- - causes of hypertension: narrowing of the arteries, a greater than normal volume of blood, or the heart beating faster or more forcefully than it should
- lifestyle choices that increase the risk: excessive alcohol use, tobacco use, too much sodium (salt) in the diet, stress
blood glucose regulation
biological factor
- impaired glucose regulation (IGR) - pre-diabetes
- refers to blood glucose levels that are above the normal range, but not high enough for the diagnosis of type 2 diabetes mellitus
birthweight
biological factor
- first weight of the newborn measured immediately after birth
- low birthweight: <2500 g
-
reasons why a baby may be born with low birthweight
- premature birth
- when a baby is born before 37 completed weeks of pregnancy
- foetal growth restriction
- when feotus doesn’t gain an appropriate amount of weight before birth due to problems with the placenta, infections, the age of the mother
- low birthweight is more prevalent for young mothers aged 15-17 and older mothers in their forties
- premature birth
-
health problems faced by low-birthweight babies
- respiratory distress syndrome (RDS)
- bleeding in the brain
- heart problems
- eye conditions
age
biological factor
- ageing → deterioration of body systems due to various forms of cellular damage that occur over time
- causes reduction of both physical and mental function → makes individual more susceptible to diseases including osteoarthritis, dementia, cardiovascular disease, depression, diabetes, hearing loss
sociocultural factors
- social and cultural conditions into which people are born, grown, live, work and age
- can often be outside of an individual’s control
social networks - family
sociocultural factor
- social disadvantages in childhood → limit opportunities for health throughout a child’s entire life
- earliest years of an individual’s life → crucial impact on their path of health and wellbeing
- limitations on parental education and income can either create or restrict their ability to provide opportunities to model healthy behaviours for their children to adopt
social networks - peers and the community
sociocultural factor
- support can be emotional (nurturing, encouraging), instrumental or physical (financial), or informational (advice)
- social networks → increase health outcomes → higher levels of self-esteem → improved mental hwb
- peer and community groups
- negative impact
- a person may be more likely to smoke if their friends do
- positive impact
- a person may participate in regular exercise if their friends do
- negative impact
socioeconomic status
sociocultural factor
- social class; key elements of income, education level, employment status and occupational type
- people with a lower SES → poorer health outcomes → higher rates of disease and disability → lower life expectancy
level of education
sociocultural factor
- high levels of education → associated with higher income and better employment prospects
- allows individuals to participate in, and connect with the wider community
- better health literacy → improved lifestyle decisions
employment status
sociocultural factor
- the workplace can promote healthy activities and behaviours, a sense of identity, social status and purpose in life, as well as additional social support
- provides source of income
- unemployment
- less likely to have strong support networks
- long term unemployment → increases risk of self-harm, suicide and attempted suicide
- limited finances
- limits healthy lifestyle choices → increases other behavioural risk factors such as tobacco, alcohol, drug use
overcrowding and homelessness
sociocultural factor
- housing - basic human right
- overcrowding and homelessness → detrimental to an individual’s health status
- overcrowding → increased stress on health infrastructure (e.g. water supply and sewerage systems)
- main impact on the health of children and can cause respiratory conditions, skin infections and meningitis
acess to health information
sociocultural factor
- culture, beliefs, affordability, education
- inability to access health information and healthcare services → detrimental to health
- misdiagnosis of disease
- lack of understanding about how to prevent disease
- increased likelihood of mortality from a disease due to lack of treatment and/or lack of knowledge of the signs and symptoms of the condition
environmental factors
- refers to the situations and surroundings that exert an influence on people’s health and wellbeing
- surroundings in which individuals exist on a daily basis
- air, water and sanitation quality; access to physical resources such as
transport, recreation facilities or healthcare; workplace; climate change and natural disasters. Other factors can include geographic location and exposure to hazards. - includes home, school, workplace, geographical location (city/rural) and the wider community
- can be direct or indirect, simple or complex, and immediate or delayed
- for some people, the physical environment may contain harmful or toxic substances that also impact their health
air, water and sanitation quality
environmental factor
-
many environmental influences are involuntary
- indoor air may contain constituents such as asbestos, moulds, radon gas, carbon monoxide and methane
-
water quality in australia
- extremely high
- water ways - high quality according to global standards → low count of faecal contamination and industrial pollution
- diseases associated with poor quality water consumption → gastroenteritis, diarrhoea, typhoid fever and hepatitis
- parasitic diseases associated with poor quality water consumption → giardiasis, dysentery, diarrhoea
- unsafe drinking water → dehydration due to loss of fluids when experiencing diarrhoea → loss of life
access to physical resources such as transport, recreation facilities and healthcare
environmental factor
-
transport systems and infrastructure
- PT → enables people to access a range of services, recreational facilities and healthcare → improves health status of a population
- rural areas
-
recreational facilities
- lack of access to recreational facilities (e.g. parks, walking and cycling tracks and well-made sporting grounds) → risk factor for chronic diseases esp. respiratory conditions
- geographic location of resources such as healthcare
workplace
environmental factor
- type of work and tasks involved → influences a worker’s risk of physical injury and illness
climate change and natural disasters
environmental factor
males and females
- an individual’s sex can lead to health differences due to the physical differences in reproductive systems, as well as hormone production and release
- gender: refers to the values, norms and expectations that society attributes to being a man or a woman
