1
Q

Define: diabetes mellitus

A

chronic condition in which the sufferer is unable to utilse their blood glucose regularly.

2
Q

Define: insulin

A

hormone secreted by the pancreas to facilitate uptake of glucose from blood into cells.

3
Q

in all cases of diabetes…

A

the process of insulin action is interrupted, causing BGL’s to be too high and cells not functioning normally

4
Q

Effects of diabetes?

A
  • Poor circulation and CVD: excess glucose in bloodstream can result in blood vessels being damaged and poor circulation. Can cause tingling, cell death, amputation of limbs and increased risk of CVD
  • Vision problems and blindness: excess blood glucose can damage blood vessels supplying the eye
  • Kidney disease: kidneys must work harder to fulter excess glucose in blood which can lead to kidney damage/disease.
5
Q

WHy does type 1 diabetes occur?

A

pancreas not producing enough, if any, insulin to allow glucose from blood to enter cells.

6
Q

Causes/risk factors of type 1 diabetes?

A

unknown, but presumed links between genetics and exposure to certain viruses (eg. influenza)

7
Q

when does type 1 diabetes occur?

A

any life stage, mainly childhood//youth

8
Q

how must type 1 diabetics manage their condition?

A

need to deliver insulin (olden days used needle and syringe, now use pumps)
Need to monitor BGL’s - fluctuations can cause tiredness, confusion and headaches
SPecial attention to diet, exercise abd BW (can affect BGL’s)

9
Q

WHy does type 2 diabetes occur?

A

due to the pancreas not producing enough insulin, or the body not using insulin effectively (insulin resistance)

10
Q

Main risk factor for type 2 diabetes?

A

being overweight - but relationship unclear. potentially:
cells are more resistant to insulin (and hence fat people are more insulin resistant)
 High levels of fat could destroy insulin producing cells, lowering level of insulin available
 Being overweight puts strain on the pancreas, as it has tried to produce enough insulin. After time

11
Q

when does type 2 diabetes occur?

A

most common in older, often overweight people, but becoming more common in younger people.

12
Q

how is type 2 diabetes managed?

A

lifestyle changes (eg. diet, exercise, weight management, sometimes medication)

13
Q

type 2 diabetes is often associated with…

A

obesity, CVD, hypertension, high blood cholesterol

14
Q

potential causes of gestational diabetes?

A

 Occurs as hormones released to assist baby’s growth and development can reduce the
 Energy requirements increase over the course of pregnancy – as does insulin needs – so there might not be enough insulin to metabolise glucose.

15
Q

when does gestational diabetes occur?

A

occurs during pregnancy (affects 3-8% of women) and goes away after pregnancy.

16
Q

effect of gestational diabetes on the baby?

A

more glucose is passed onto the baby, resulting in increased gestational growth, resulting in higher birthweight and lower blood glucose, but not diabetes, in the baby.

17
Q

effect of gest di on the mother?

A

more likely to get type 2 diabetes

18
Q

why is diabetes mellitus a NHPA?

A
  • Major contributor of BOD, both YLD (esp. type one can cause long term disability) and YLL (risk factor for conditions which often result in death).
  • Risk for type 2 diabetes can be reduced through lifestyle factors
19
Q

direct costs to indv?

A
  • Ambulance transport if a person has a diabetic coma (due to diabetes being uncontrolled)
  • Patient co-payments for insulin
  • Patient co-payments for doctor/dspecialist services (often require ongoing treatment from them)
20
Q

direct costs to comm?

A
  • Medicare contribution to doctors and specialists consultations.
  • PBS contributions for insulin
  • Health promotion programs such as Life! Taking action on diabetes
21
Q

indirect costs to indv?

A
  • Paying for carers

* Lost income when unable to work

22
Q

indirect costs to comm?

A
  • Government contribution to cost of carers
  • Loss of productivity
  • Social security payments
  • Lost taxation revenue
23
Q

intangible costs to indv?

A
  • Loss of self esteem
  • Anxiety about the possibility of condition progressing – can lead to blindness and limb amputations
  • Frustration over making lifestyle changes
24
Q

intangible costs to comm?

A
  • Anxiety over possibility of it progressing

* Frustration over making new lifestyle changes

25
Q

biological determinants?

A

Age
• T2 Increases with age – highest risk over 55
• T2 Rates in young people increasing – due to increased obesity rates
Hypertension and high blood cholesterol
• unsure whether they cause obesity and hence type 2 diabetes, or whether diabetes causes them.
Impaired glucose regulation
• Precursor to type 2
• IF not managed, can lead to it.
Genetic predisposition:
• more likely if another family member has
Body weight
• Overweight/obesity a risk factor for T2, unsure why.

26
Q

behavioural determinants?

A

obacco smoking
• Leads to higher BGL  insulin resistance  type 2
• More likely to be sedentary/overweight
Excessive alcohol consumption
• Energy dense  obesity  TD and gest
Physical activity
• Inactive  weight gain  obesity  T2 and gest diabetes
Dietary behaviour
• Energy dense/high fat foods  obesity - type 2 and gest

27
Q

physical environment determinants?

A

Work environment
• If doesn’t promote incidental physical activity, more type 2
Transport
• Passive transport  obesity  T2
Access to recreational facilities
• If not  not enough exercise  obesity  t2

28
Q

social determinants?

A

Socioeconomic status
• Lower  higher rates of obesity  higher rates of T2/gest
Occupation
• If managerial/sedentary  obesity  t2
Food security
• None  might eat energy dense, processed foods  obesity  T2 and gest
Early life experiences
• Low birth weight  increased risk of T2
• Malnutrition could damage insulin producing cells in pancreas.

29
Q

whawt is the health promotion program?

A

Life! taking action on diabetes

30
Q

Who is life! by?

A

: funded by the Victorian state gov, administered by Diabetes Australia (Victoria branc), who train workforce required for implementation.

31
Q

aims of Life!?

A

 Prevent people from developing type 2 diabetes – specifically to prevent its onset in 25,000 high risk Victorians over a four year period.
 To contribute to early diagnosis in those who have type 2 diabetes but don’t know they do.

32
Q

life! is aimed at…

A

high risk Victorians - Victorians over 50 and all Aboriginal and Torres Strait Islanders.

33
Q

describe the life! program

A

 Delivers a program to the 25,000 high risk Victorians
• These participents identified through online/phone diabetes risk test. Note – only people with RISK of diabetes, not already with diabetes, are chosen.
• Conducted in metropolitan, rural and remote areas.
• 6 group sessions over 8 months – educates individuals about type 2 diabetes and the lifestyle changes (diet and exercise) to reduce risk.
o They analyse their own lifestyle, set goals for behaviour change and aim to lose atleast 5kg over the program.

34
Q

other elemts of LIfe!?

A

 Website: contains resource/education to individuals and health professionals about the prevention of type 2 diabetes. Including recipes and success stories
 Mass media campaigns: eg. Don’t be the type to leave it too late: woman saying healthy eating and exercise is vital, but wasn’t always healthy. She is swimming and gets out of pool and reveals amputated leg
