Q

How are the determinants of social health found

A

First they look at the whole population to see who is at risk, then they use the Dahlgren and Whitehead model to identify the effects of different determinants on different populations health, then finding the inequities and inequalities and how/why to reduce them.

45
Q

The ability to change behaviours from habitus depends on

A

the social group

46
Q

What is social and community networks

A

The role of families, friends and people working and living in the same community influences what is thought of as normal and acceptable behaviours. Another part of this is the social capital of an community

47
Q

What is social capital

A

This is the level of trust between a community and the value of socially uplifting behaviours in that community that forge bonds between diverse people - eg civic participation, volunteerism

48
Q

52
Q

Define Agency (in pophlth)

A

The capacity of an individual to act independently and make free choices.

53
Q

Where does structure and agency lie on the DW model

A

Structure is in the three outermost levels (2/3) , Agency is in the two innermost (1)

54
Q

The determinants of health are a framework to help you

A

identify risk and protective factors

55
Q

Protective factors should not be

A

‘not’ something

56
Q

By identifying risk and protective factors, this helps us to think of interventions. what 2 things must you consider when thinking about tackling these factors ?

A

Different factors can affect others, so distal factors may affect proximal factors. Factors operate at different scales= person- micro, community/ family- meso and society = macro

57
Q

Inequities in health outcomes result from

A

inequities in health opportunities

58
Q

Opportunities could be thought of as

A

chance of exposure

59
Q

Define inequalities

A

measurable difference/ inequalities in health

60
Q

Differences in health experiences and outcomes between different populations according to ethnicity, gender, area is an example of

A

inequalities

61
Q

Inequalities help us to see the

A

social gradient

62
Q

Define inequities

A

Inequalities that are unfair/ based from injustice/ imbalance of power resulting in health outcomes

63
Q

Define health inequities

A

Differences in the distribution of health resources and services across populations that do not reflect the needs of that population

64
Q

What is the rationale for Maori health promotion / interventions (what hasn’t been happening)

A

Maori as an indigenous people have not had their rights fulfilled. Evidence of persistent inequalities. Mainstream health interventions have not been effective with for Maori than for non-Maori. Maori health is everyone’s responsibility.

65
Q

What is the state of Maori health at the moment

A

There have been systemic inequities in health outcomes, exposure to determinants of health, access to quality healthcare, and representation in the health workforce at all levels created by historical and contempory factors.

66
Q

Ethnic inequalities have been created and perpetuated therefore they can be

A

reduced, eliminated and prevented

67
Q

What causes health inequalities

A

the unequal distribution of health risks and opportunities (social determinants)

68
Q

What is health promotion?

A

set of strategies/ approaches to addressing health inequities

69
Q

What are the main failings of conventional health promotion

A

Based on western models, it has a one size fits all mentality, that focuses on the superficial, rather than structural approach. This isn’t rooted in Maori values and is poorly adapted for the Maori realities.

70
Q

What are the prerequisites of the Ottawa charter

A

Peace, shelter, education, food, income, stable eco-system, sustainable resources, social justice and equity

71
Q

What is a Maori health promotion model

A

Te Pae Mahutonga- the Southern cross

72
Q

What are the 6 parts of Te Pae Mahutonga

A

4 Key tasks (Mauriora, Waiora, Toiora, Te Oranga) and 2 prerequisites (Nga Manukura and Te Mana Whakahaere)

73
Q

What is Mauriora

A

The security of cultural identity and means access to Te Ao Maori (the Maori world). Including Te Reo, Tikanga Maori (customs) , Marae, Maori environments and ecological resources.

74
Q

What is Waiora

A

Environmental protection and a recognition of some of the physical determinants of health, including clean water, clean air, vegetation and wildlife, less noise pollution. (keeping people in harmony with the environment)

75
Q

Can Te Pae Mahutonga be applied to other whole population approaches

A

yes

76
Q

What is Toiora

A

Healthy lifestyles - depending on personal behaviour and as Maori experience more risk factor, a shift from harmful lifestyle takes targeted interventions, risk minimisation, cultural relevance, risk management and positive development

77
Q

What is Te Oranga

A

Participation in society - the participation of Maori individually and collectively in decision making at all levels. The ability to have ownership and access to the resources to fulfill the other three stars

78
Q

What is Nga Manukura

A

Leadership - Leadership from health professionals in partnership with community leadership to enable and empower them to do things for themselves.

79
Q

What is Te Mana Whakahaere

A

Autonomy - having the political structures and processes in place to give communities ownership and control over health promotion finding community based solutions. Self governance

80
Q

What are the principles of Maori Health Promotion

A

Focusing on the underlying determinants to achieve sustainable change
Maori decision making at all levels
Allows for diverse realities
Using contemporary methods, valid approaches. Knowing the dynamics of the community to have leverage
Give leadership to communities

81
Q

What is the liberation

A

Removing barriers to good health outcomes for everyone by empowering them rather than putting bandaids

82
Q

Epidemiology can play a central role in preventing disease by

A

unraveling the causal pathway, directing preventative action, evaluating effectiveness

83
Q

Why is preventing disease becoming more needed?

A

The cost of treating disease (to healthcare system and consumers) and the limitations of curing disease causes disparities between different populations utilisation/ access to technological solutions therefore creating inequalities

84
Q

What is the goal of health professionals try to reduce risk factors, identify early stages of disease so that it can be treated early?

A

Its so the number of people presenting to curative health services can be reduced and they can then provide equitable care to all population groups

85
Q

What are the three types of population health approaches and what are the two ways they can be delivered ?

A

Health promotion, disease prevention and health protection– delivered either by population based (mass) strategies or High risk (individual) strategies

86
Q

What is the population based strategy? (focus, aims, useful)

A

Its focus is to address WHOLE POPULATIONS. Aims to reduce the health risks/ improve the outcomes of all individuals in the population. Useful for widespread diseases with a common cause eg immunisation

87
Q

What is the High Risk individual strategy (focus, aim, useful)

A

Focus on individuals who are perceived to be high risk. Aim to improve their health/ reduce their risk to bring them back to the normal population level. Useful for matching individuals and their concerns. eg needle exchange programme

88
Q

What are the advantages of a high risk strategy?

A

Targeted towards individuals-> appropriate
High individual and Clinician motivation -> strong justification of treatment
Cost effective use of resources -> the people who need it
Favourable benefit to risk ratio-> Benefits outweigh the risks

89
Q

What are the disadvantages of high risk strategy?

A

It has limited potential -> not radical and even if some individuals are high risk, its only beneficial if they make up the majority of the cases of disease
Screening for high risk individuals is costly, needs to be done at different stages of life
Its effects are temporary-> need to keep screening
Behaviourally inappropriate-> requires people to step out of social norms

90
Q

What are the advantages of a population based strategy?

A

Radical-> addressing the underlying causes
Large potential benefit for the whole population-> eliminating risk factors
Behaviourally appropriate-> changes the societal norm

91
Q

What are the disadvantages of a population based strategy?

A

Small benefit to individuals-> not all of them are at risk, no immediate reward
Low motivation of individuals
Whole population is exposed to the downside of the strategy
Low benefit to risk ratio-> not everyone is reaping the reward but everyone has the downsides

92
Q

What is Health Promotion (acts on, purpose, involves)

A

This acts on the determinants of Well being. Its purpose is to empower people to make healthy choices. It involves whole populations in everyday contexts.

93
Q

What is primary health care

A

Healthcare services that are the first point of contact, a regular source of healthcare . Eg GP

94
Q

What is secondary health care

A

The specialist you are referred to by your GP

95
Q

What is tertiary health care

A

Institutionalised health care services such as rehabilitation, hospital based care.

96
Q

When/where was the Alma Ata declaration for primary health care made

A

1978 International conference for primary healthcare in Kazakhstan

97
Q

What was so special about the Alma Ata

A

Focused on a health promotion approach to healthcare, looking to protect & promote health of all, primary healthcare was important. It also addressed the social determinants - the idea that prerequisites are required for people to be healthy- no war, food, water, income etc

98
Q

When/where was the first international conference on health promotion made?

A

21/11/1986 , Ottawa

99
Q

What is so special about the Ottawa Charter for health promotion

A

Recognises the human rights of health, assigns responsibility to the individual and collective, advocates an equity in good health opportunities, and pushes the idea of health for all will increase the social and economic development of all

100
Q

What are the three basic strategies of the Ottawa Charter

A

Enable -> provide opportunity for people to make informed choices (individual)
Advocate -> create favourable societal environments to get equity in health (systems)
Mediate -> bring together opposing groups/ individuals to work for the greater good of healthcare

101
Q

What are the 5 priority action areas of the Ottawa charter

A

Develop personal skills, strengthen community action, create supportive environments (physical), Reorient health services towards primary healthcare, build health policy

102
Q

What is disease prevention strategies (focus, goal)

A

Focuses on the disease. Identifies features about the disease prevalence and risk and works to reduce the occurrence of disease in the population

103
Q

What is the primary, disease prevention strategy and when is it implemented

A

Primary occurs before the biological onset and limits the occurrence of the disease by controlling specific risk factors and causes - eg vaccine

104
Q

What is the secondary disease prevention strategy and when is it implemented

A

Secondary occurs just after symptoms are occurring and reduces serious consequences of the disease eg- screening for early diagnosis

105
Q

What is the tertiary disease prevention strategy and when is it implemented

A

Tertiary occurs just before the outcome of the disease (recovery,death or disability) and helps to reduce the progress of complications of the established disease. eg. rehabilitation

106
Q

What is health protection (focus, goal)

A

These focus on environmental hazards. Its goals are to manage environmental risk by assessing and monitoring hazards, communicating this to the public and starting regulations on occupational health

107
Q

Can there be overlap between Health protection, health promotion and disease prevention?

A

yes

108
Q

It is before the disease is occurring-> what population health approaches am I expecting to be occurring?

A

The whole of health promotion, and the primary part of disease prevention, some parts of health protection
