Term 2 test Ch 6 Flashcards
2 leading causes of death in Canada?
Cancer 28%
Heart Disease 19%
Illness and early death could be substantially reduced if people would adopt ____
lifestyles that promote wellness
health behaviours definition
activities to maintain/improve health or prevent disease
*regardless of health status/whether activity actually improves health
well behavior
activity that maintains/improves current good health and avoid illness
well behaviour examples
diet, exercise, getting vaccinated
symptom-based behaviour
any behaviour we do when feeling unwell
how people respond to illness
symptom based behaviour examples
complaining about symptoms, seeking advice
sick role behaviour
- activity taken to adjust to a health problem
- expectations/responsibilities adopted by a sick person + imposed beliefs on others
Alameda County Study (1965-1999)
Link btwn lifestyle and health
7 risk factors/health habits associated with poor physical health and increased mortality in Alameda County study
- Smoking cigarettes- amplifies effect of other substances
- Excessive alcohol
- Obesity
- Physically inactive
- Eating between meals
- Not eating breakfast
- Sleeping < 7-8 hours/night
Top 3 risk factors in USA Health and retirement study (1992-2014)
- Current smoker
- Hx divorce
- Hx alcohol abuse
- Recent financial difficulties
- Hx unemployment
- Hx smoking
- Lower life satisfaction
- Never married
- Hx food stamps
- Negative affect
Findings of the PURE study (prospective urban rural epidemiology)
Higher total mortality is associated with higher carbohydrate intake and lower total fat intake
Sugar correlated to increased cancer + decreased intake of complex carbs/fiber= increased cardio disease
Pro-inflammatory effect of processed carbs
Increased fruit/vegetables/legume consumption is associated with a lower risk of mortality
Higher risk of IBD with ultra-processed food
Main issue with the PURE study?
Difficult to research due to confounding factors eg. can’t control diet
Primary prevention
actions taken to avoid disease or injury
*person currently does NOT have a disease
Can be undertaken by either individual or society
Health promotion initiatives
providing information on how to stay healthy
health promotion initiatives are aimed at ____ prevention
primary
secondary prevention
identify/treating an illness early with the aim of stopping or reversing the problem
*person already has the disease
primary prevention examples
exercise
seatbelt wearing
flossing
immunizations/vaccines
handwashing
physical distancing
mask wearing
secondary prevention examples
medical exams
cancer screening follow-ups
seeking medical care for pain
sick role behavior of taking meds
treating flu
Learning Objectives: Define health behaviours
Activities taken to maintain/improve health, regardless of health status
Well behaviour
Symptom-based behaviour
Sick role behaviour
Learning Objectives: examples of health-compromising behaviors
Alameda County study:
7 risk factors/health habits associated with poor physical health/increased mortality (premature death)
- smoking
- excessive alcohol
- obesity
- physically inactive
- unhealthy snacking
- skipping breakfast
- not enough sleep
USA Health and retirement study: factors associated w/death
1. Smoking
2. Hx divorce
3. Hx alcohol abuse
4. recent financial difficulties
5. Hx unemployment
6. Hx smoking
7. lower life satisfaction
8. Never married
9. Hx food stamps
10. Negative affect
PURE study (ongoing) Prospective Urban Rural Epidemiology
- High carbs/Low fat diet associated w/ higher mortality
- Low-carb diets also associated with lower life expectancy
- Only bad fat is trans fat
- Increased fruit/veg/legume diet associated with lower mortality
- higher intake of ultra-processed foods associated with IBD
Learning Objectives:
Factors in health behaviors: problems
eg. learning/personality, less rational processes, psychological factors: empathy and antisocial traits
Factors within the individual include:
- attitudes, perceptions, difficulties changing habits, lack of resources, low self-efficacy (the belief that we can succeed)
Interpersonal factors
- social support, conflicts among behaviors in family systems, disruptions to behavior
Health belief model
-Threat/perceived risk
(belief in health threat)
-cues to action from a physician
+ —> likelihood of
-pros/cons health behavior
Cognitive adaptation theory
not fully accepting physiological risk can result in better coping with risk
ie. optimal optimism encourages compliance
eg. 1992 study of men w/HIV found that HIV positive men who inaccurately, but optimistically believed they could halt the progression of AIDS practiced better health habits than those who were pessimistic
Health belief model applied to flu vaccine
-I haven’t had the flu shot which puts me at risk of getting sick from the flu
-cues to action from a physician
+ -
-I believe the shot works. I don’t believe the flu shot can give you the flu
–> likelihood of getting flu vaccine
Theory of planned behavior
ASN PBC
health behavior is the direct result of behavioral intentions influenced by 3 key factors:
- Attitude regarding the behavior (judging whether it’s good/bad)
- Subjective norm
- Perceived behavioral control //self-efficacy: belief of being able to achieve a goal
