Q

What are health behaviours?

A

Behaviours employed by people to enhance or maintain their health
Become health habits

77
Q

Define health habits

A

Health behaviour that is well established and is preformed automatically
If reinforced early, becomes resistant to change

78
Q

What are some influential factors of health behaviours?

A 
Socio-economic factors 
Age 
Gender
Values 
Personal control 
Social influence 
Personal goals
Perceived symptoms
Access to health-care
Location
Cognitive factors
79
Q

What strongly affects health habits?

A

Socialization: parents as role models
Teachable moment: educational opportunity
Closing the widow of vulnerability: adolescence

80
Q

What are some benefits of identifying risks?

A

May eliminate or prevent poor health habits
Efficient and effective use of health dollars
Help identify risk factors in patient population

81
Q

What are some problems with identifying at risk people?

A

Hypervigalence - over sensitive to stressors

May become defensive and disregard risk factors

82
Q

What are some ethical issues that must be considered when identifying people at risk?

A

Do you identify at-risk people of risk is low
Identification may initiate symptoms
There might not be a clear intervention
Interpersonal issues may arise

83
Q

What is the main goals in health habits in elderly and what factors must be considered?

A 
Improve quality of life
Factors:
Exercise
Participation in social activities
Monitor alcohol consumption
Controlled diet
Vaccination
84
Q

What are some other factors to consider when looking at health behaviours?

A 
Gender and ethnic differences can influence vulnerability to particular health risks:
Alcohol consumption
Smoking 
Drug use
Exercise
85
Q

How can we change health behaviours?

A

Educational appeals: credible, colourful, concise
Fear appeals: use feSr to change behaviour, may be counter productive, coupled approach
Message framing: messages that stress benefits
- loss framed works best for high risk
- gain framed works best for low risk

86
Q

What is health behaviour change and what are some models of health behaviour change?

A

Changing beliefs instead of attitudes
Social cognition model: expectancy-value theory, engage in behaviours that will be successful and they value
Health belief model: perception of threat, perceived threat reduction
Planned behaviour model: health behaviour is a result of a behavioural intention
Transfheoretical model: includes stage of change, has treatment goals

87
Q

What is the theory of planned behaviour?

A

Direct result of behavioural intention
Three components:
- attitude towards specific action: likeness and evaluation
- subjective norms: what do other think? Motivation to comply?
- perceived behavioural control: capable of preforming the behaviour, achieve intended effect

88
Q

Describe the transtheoretical model?

A

Also referred to as the stages of change model

89
Q

What are the stages of the transtheoretical model?

A

Precontemplation: no intention of changing behaviour
Contemplation: aware of the problem but have not made a commitment
Preparation: intention is there but no action, minor modifications may have been initiated
Action: modify behaviour, commitment made
Maintenance: prevent relapse, consolidate gains

90
Q

What is cognitive behavioural therapy?

A

Patient targets behaviour with individual changes
Modification of internal monologue
Behaviour change shifts from therapist-patient to pt alone
Factors include:
- self-observation/monitoring
- classic conditioning
- opérant conditioning: linked to positive reinforcer

91
Q

What factors are included in cognitive behavioural approaches?

A

Modelling: emulate and reinforce behaviour
Stimulus control: removed associated triggers
Self control: use positive reinforcement positive/negative reward

92
Q

What are preventable injuries?

A

One of the major preventable deaths
Include:
Home and workplace injuries
Motorcycle and automobile accidents

94
Q

What is sun tanning become a problem?

A

Increased uv radiation
Ineffective use of sunscreen
Changing health behaviours adolescents

95
Q

How does exercise effect health behaviour?

A 
Aids with mental and physical health: can help just as much as medicine 
Includes aerobics (biking, swimming) not isokinetic (weightlifting)
96
Q

How much exercise do we require a week?

A

150 minutes per week

Improvement of psychological factors

97
Q

What are the determinants of regular exercise?

A 
Gender
Age
Race
Support group
Self motivation 
Settin
98
Q

Why do people resist modifying diet?

A

Choice is not self motivated
Health vs image
Restrictive, expensive, laborious plans
Related to stess

99
Q

How are family and community interventions used to modify diet?

A

As a kid, you are what your parents made
Don’t cook much until your older
Might not always be nutritious food
Learn that lifestyle and becomes basis of diet
Must modify what is being consumed as a family
