Exam question1

Answer plan question 1a and1b

• Draw a Venn diagram to show the differences between males and females on the graph.

• Why do more males than females suffer from some diseases?

• Why do more females than males suffer from some diseases?

11

Answer to question 1a

• Males- high incidence of injury, e.g. traffic accidents, suicide, drug abuse, e.g alcohol and heroin. Also high in mental disorders, e.g. schizophrenia.

• Females – high incidence in depression, social phobia and eating disorders

12

Answer to question1b

• Road traffic accidents are high for males because of their risk taking behaviour, eg. speed and drug use.

• Suicide and depression are high for males because men are less likely to communicate emotions, and more likely to hide feelings. Women seek help more often.

• Eating disorders for females are high because women are pressured to conform to unrealistic body images.

13

What factors affect our health?

Exam question 2

17

Reading the graph

• This graph is difficult to interpret.

• Circulatory diseases and cancers are on the same line

18

Answer question 2a

• The proportion of deaths from infectious diseases decreased this century, while circulatory diseases and cancers account for most of the deaths in males. Respiratory diseases and injuries have maintained a fairly constant contribution to the death rate.

19

Answer Question 2b

• Reduction in infectious diseases due to improved sanitation,medication,technology and vaccination.There has been an increase in diagnosis of circulatory diseases and cancers. Other causes include suicide and accidents.

20

Exam question 3

a. Discuss the contribution of lifestyle and behaviour choices to burden of disease in Australia, as indicated in the graph above. (4 marks)b. Select an area of the National Health Priority Areas for Australia that is reflected by Statistics above. Outline a health promotion initiative that has focused on one of theserisk factor areas. (6 marks)

21

answer plan 3a

Which factors are lifestyle choices?

Tobacco Physical inactivity

Overweight and obesity

Lack of fruit and vegIllicit drugsOccupationUnsafe sex

There are two factors that are affected by

lifestyle but are also Environmental.

These are hypertension and high blood cholesterol

22

Answer plan 3a.

Factors influencingMen more than

women

TobaccoOverweight

obesity

Lack of fruit and veg

High bloodcholesterol

Illicit drugsOccupationUnsafe sex

23

Answer to exam question 3

• a. Eight out of the ten risk factors are related to lifestyle choices. Hypertension and cholesterol are partly due to genetics.

• For men, drug use is markedly higher than for women, while females have higher risk from not exercising.

• b.NHPA areas include Cardiovascular health – an initiative would be the promotion of healthy foods in school canteens and sport participation in schools to reduce levels of obesity in children.

24

Groups who are at risk of ill health in Australia

• Indigenous Australians

• Socioeconomically disadvantaged

• Rural and Remote population groups

• Men and women

25

How to remember the four groups

• Jack and Jill (men and women)

• Went up the hill (rural and remote)

Can you think of an ending that will include indigenous and socio-economically disadvantaged groups?

33

Answer to exam question 4

a. Income affects money available to spend on food, medical services, housing, basic services, e.g. water and heating. Unemployment affects income, and may affect self-esteem and mental health. Education levels affect occupation choices, and knowledge of health and how to access health services.

b. There is a general trend for young people with highest disadvantage to report their health status as only fair or poor. This trend relates to men more than women.

34

Nutrition status can be defined as the state of health of an individual or group in relation to their nutrient intake.

Nutrition status is measured by:-

• Food consumption surveys- Measure food being consumed or available to be consumed

• Nutrition surveys- measure food and drink intake of a population and analyse the nutrient content

• Body mass index – measures the amount of body fat on a person

35

Nutrients required for hard and soft tissue, energy, blood and their food sources

Exam question 5

• Andrew, aged 17 has come to spend the year with his aunt and uncle in another city. His aunt is surprised by how much Andrew eats compared to her own son, Richard aged ten.

a. Compare and contrast the nutrient requirements of Andrew and Richard (6 marks)

b. Briefly outline what differences there might be

in nutritional requirements for the two boys in 10 years time. (6 marks)

44

Answer plan for 5a

• Draw a Venn diagram showing the similarities and differences between the nutritional requirements for both boys.

Answer plan for 5b

What are the factors that influence energy requirements?

45

Answer for question 5.a) Changes in energy requirements in adolescence are

due to:Growth spurt – body size, height, weight and high activitylevels.b) Factors that influence energy requirements are:Gender – boys have higher BMR due to higher ratio of

muscle to fatGrowth – different rates between childrenHormones – variation in hormones regulating metabolismPhysical activity – variation in exercise levelsState of Health – high energy use required to fightinfection.Emotional well – being: stress levels affect energy use.
