Models of Health Flashcards
1
Q
What is a model
A
A “model” is a perspective, or a way of looking at things.
2
Q
WHO’s definition for health?
A
“health is more than the absence of disease or infirmity [which means illness or disability], but is a complete state of mental, physical, and social well-being.”
3
Q
Other ‘dimensions of wellness’ to add to WHO’s health definition?
A
- Emotional wellness
- Environmental or planetary wellness
- Spiritual wellness
4
Q
What is health (described as a process rather than a state)
A
the process of doing your best most of the time to mobilize your resources to cope with the challenges of life.
5
Q
What was the main message in A New Perspective on the Health of Canadians?
A
many of the leading causes of death and disability at that time were associated with known, preventable risk factors: motor vehicle crashes, heart disease, lung cancer, suicide.
6
Q
What model was created from the insight provided by A New Perspective on the Health of Canadians
A
Risk factor model
7
Q
The risk factor model brought what two strong approaches to health
A
- At the population level, targeting interventions to groups at high risk of disease. For example, knowing that alcohol-related car crashes are especially common among young adult males could produce changes in licensing, law enforcement, or social marketing aimed at that group (social marketing is discussed in a separate unit by the same name).
- At the individual level, raising awareness of the connection between health behaviours and health outcomes, and giving knowledge and skills that will help people to change their risky or unhealthy behaviours.
8
Q
Your definition of health will influence what two things?
A
- The scope of things you would include in “health promotion”
- The way you would approach an issue e.g., detect disease, prevent disease, or promote wellness.
9
Q
Medical model/risk factor model of health vs. “holistic model” and the “wellness model”?
A
Medical model/risk factor model: “health” to be the absence of signs or symptoms of disease
Wellness model: health as MORE THAN the absence of disease, but a complete state of mental, physical, and social (and emotional, environmental, and spiritual) well-being
10
Q
What does the holistic model/wellness model challenge an individual to?
A
- Become aware of the connections between health behaviour and health outcomes
- Exercise more conscious control of their thoughts and behaviours
- Pursue higher level of wellness
11

41
What happens when you fail to stay current with indicated preventative services and failure to control disease risk factors
Spiral of unnecessary illness, health care costs, and disability---all widening the gap between the need for health care and the resources available to pay for it
42
What emotions do individuals who chronic disease and disabilities associated with obesity experience
Anxiety and depression
43
End result of researching molecular biology of obesity
Develop better understanding of what leads a proportion of the population to become obese in an environment that requires almost no PA and provides calories in accordance with desire
44
End result of researching genetics and behavior
Help us understand why some individuals who were once obese are able to achieve sustained weight loss whereas most others fail at this goal
45
Is obesity epidemic primarily due to an increase in the consumption of calories or a decline in physical activity?
Unknown however fundamentally result of energy imbalance: more calories consumed than burned
46

48
How do we create environments that make it possible and rewarding for individuals to avoid obesity in the first place and maintain weight loss if they were obese at one time
- ensure communities allow people to move around by foot or bike
- make low-calorie dense foods available at prices
- provide foods and drinks that meet nutritional goals in schools
- ensure students have adequate levels of P.E.
- develop and implement programs that market the benefits and pleasures of physical activity and low-calorie foods to offset the financed and highly sophisticated campaigns of the food, alcohol, spectator sport, and entertainment industries

63
Since obesity is not primarily a medical problem and can't be controlled by primarily medical approaches, what is it controlled by and what approaches are essential
- obesity anchored in society and culture
| - structural approaches essential
64
Why are environmental and policy solutions called passive solutions
They achieve objectives for the good of society and people in it w/out requiring individual behaviour change and perhaps even w/out knowledge of individual
65
Why are passive strategies more successful than those requiring decision making
they do not require health to be the basis of decision making and also because they help to reshape community norms …This strategy has been summarized by the phrase ‘to make healthy choices the easy choices'
66
3 strategies proposed by Milio?
1. General • Development of an intersectoral, national policy on obesity control • Educate government agency leadership about the inadvertent impacts of their policies on eating and physical activity
2. Physical activity related • Long-term planning of towns and city centers to promote walking and cycling • Measures to slow or ban traffic in some areas • Remove sales tax on the purchase of exercise equipment • Change building codes to increase the use of stairways • Develop adequate safety guidelines and liability legislation for sports equipment and exercise or recreational facilities • Protect open spaces through zoning and land-use policies • Give incentives to employers who provide for physical activity breaks or release time
3. Food and eating related • Label the fat and caloric content of foods in restaurants and take-out establishments • Setting and enforcing guidelines for the fat content of school and hospital meals • “Silent” alteration of the content of restaurant foods or processed foods through gradual changes in food processing or food preparation • Banning some types of food advertising on television • Regulation of television commercials in children’s programming • Requiring nutrient content information as a part of food advertisements • Use price supports to promote or discourage consumption of certain foods • Levy taxes on certain foods and use the revenues to support other health promotion activities
67
What is a campaign
a connected series of operations designed to bring about a particular result
68
Health communication campaigns have what qualities

69
To understand health communication campaigns we should look at what six elements
1. Target group(s)
2. Central messages
3. Strategy
4. Tactics
5. Outcomes (results)
6. Costs (and ideally cost/benefit analysis)
70

```
2. Central Messages
• It is not your fault
• Do not be afraid of being judged
• There is help available
• “Just be open”
This may be a bit too many messages. Maybe it is easier to maintain focus and have impact with one or two key messages.
```
```
3. Strategy: Four Pillars

1. Target: Smokers age 40-54
2. Central messages
• Quitting smoking may be difficult, but it is possible and it is worth it.
• It is important to develop a quit plan.
3. Strategy (the big plan)
I don’t know what the strategy was.
4. Tactics (the specifics)
• Eight 30 sec television ads
• Call-to-action to contacts: 1-800 O-Canada; gosmokefree.ca
• Website where Bob & Martin made journal entries
• Other advertising (billboards, print, mail to physicians) Text of one TV spot in which Bob thinks about quitting
• "I know. It's tough to be a smoker these days...
• I'm outside and it's minus 20. No problem - I like winter.
• My breath stinks? I've got mouthwash.
• Food's got no taste? No problem - I use salt.
• I'm getting sick of this. That's the problem." Sample daily quitting message
• "What makes you reach for a cigarette?
• In addition to physical cravings, many people smoke in response to certain emotions....
• We all feel these things, but we can choose how we respond. What else could you do with your emotions instead of smoking? What else could you do to feel pleasure when you quit? Just think about it for now and we'll talk more about this in future messages." Strategic alliance with Reader’s Digest
• Subscribers got Health Canada's self-help guide to quitting
• Those who had requested smoking cessation info got letter
• Doctors got letter (poly-bagged with Reader's Digest), informing them of Health Canada's cessation resources and encouraging them to use/distribute them to patients
5. Outcomes

• Media placement $ 6,400,000
• Evaluative research $ 237,000
72
Examine VERB. It's what you do campaign:
1. Target group(s)
2. Central messages
3. Strategy
4. Tactics
5. Outcomes (results)
6. Costs (and ideally cost/benefit analysis)
1. Target group • Children aged 9 to 13 (“tweens”) Targeted because at this age they become more independent • Parents = secondary target, to support & encourage tweens’ participation in PA 4.2. Central messages • PA is a good way to spend time with friends • PA is fun • PA is cool They later dropped the first message because it was giving a mixed message, since socializing may connote sedentary time. They added messages on mastery & inclusiveness for older tweens
3. Strategies I don’t know what the strategy was. 4.4. Tactics • TV ads on Nickelodeon, Disney Channel, etc. • Website • Text messages to kids: “Remember to have fun by being physically active” • Yellowball o 500,000 yellowballs (about 18 cm = 7 “ diameter) with campaign name and logo were passed out
o Tweens encouraged to play with ball with their friends, then blog about its whereabouts. o View photos of Hillary Duff with her yellowball and read her blog about getting physically active
Other advertising: radio, theatres, billboards, print (e.g., in Sports Illustrated for Kids, Teen People) • Website, whose interactive components included o ability to create virtual character identities and blog about their physical fitness activities o virtual “playground” that included jokes and games for kids to explore
5. Outcomes A random sample of children and parents were surveyed April-June 2002, before the launch of VERB. This same group of individuals surveyed again April-June 2003 • 74% of children aware of VERB • Those who were “Informed” (i.e., had heard about Yellowball) reported 34% more free-time physical activity in the week preceding survey than the “uninformed” • 21% of the balls were passed on. • Nearly 17,000 blogs were received. • One ball was passed 31 times while another ball traveled 39,940 miles. 4.6. Costs • $339 million (USD) over the five years (= $68 million per year) • Campaign ended because of funding shortfall • Difficult to calculate cost/benefit:
o If reached 21 million people, then $16/person o But, what is cost/participant-hour of PA? • Advertising production, especially for TV, is expensive.

88
Cause for global obesity epidemic
result of inc urbanization n globalization, coupled with significant changes in food environment
89
Obesity is the consequence of automatic n largely uncontrollable responses to an environment w/excess food availibility n aggressive n unrelenting cues that cause people to eat too much
.
90
Ten human characteristics exploited to make people eat too much
1. Physiological response to food n to images of food
2. Inborn preferences for sugar n fat
3. Hardwired survival strategies
4. Inability to judge caloric content
5. Natural tendency to conserve nrg
6. Mirror neurons
7. Conditioned responses to stimuli
8. Priming
9. Automatic stereotype activation
10. Limited cognitive capacity
91
1. Physiological response to food n to images of food
- dopamine secreted when see food & creates craving
| - exploited: vending machines
92
2. Inborn preferences for sugar n fat
- people born w/natural preferences for sweets n fat
| - exploited: placing candy at checkout
93
3. Hardwired survival strategies
- people are wired to eat a greater variety of foods
| - people respond to variety by consuming larger total quantities of food
94
4. Inability to judge caloric content
- people cannot judge volume n portion amts
| - exploited: restaurants serve too large portions
95
5. Natural tendency to conserve nrg
- people naturally attracted to foods conveniently prepared in order to save nrg
- exploited: make foods for on the run
96
6. Mirror neurons
- people tend to mimic behaviours of others
| - exploited: modelling eating behaviors, people eat more when with others
97
7. Conditioned responses to stimuli
- humans have tendency to respond to conditioning
| - exploit: branding... people learn to buy that brand rather than product
98
8. Priming
- priming evokes specific memories that make people more disposed to act in particular way
- exploit: in restaurants people eat faster when faster music played n vice versa
99
9. Automatic stereotype activation
- exploit: advertisers exploit fact that we respond more favourably to images of people like us n customize marketing to reflect appearance of target group
100
10. Limited cognitive capacity
- people can only process limited amt of info at one time, when over loaded tend to make decisions impulsively
- exploit: default options r items high in sugar n fat
101
how to reduce people's overwhelming desire to eat in response to environmental cues
number n type of cues needs to b limited n regulated
| - regulations addressing food cues, food availability, portion sizes, n advertising are needed
