Determinants of PA and supporting behaviour change (wk8) Flashcards
What are health inequalities?
Health inequalities measured by differences in health outcomes among different groups of people. In England, life expectancy varies depending on where people live. People living in the most deprived areas have a life expectancy a decade shorter than those living in the least deprived areas. Covid-19 has widened health inequalities in England. Disproportionate effect on those already experiencing health inequalities – living in the most deprived areas and people from ethnic minority backgrounds.
Describe the different determinants of health and PA + PA interventions
Behaviour, individual person, lifestyle factors, social and community networks, living and working conditions, general socio-economic, cultural and economic conditions. Different jobs require different states of activity, such as with stairs.
-PA interventions -> Necessary to ensure that more people achieve the health benefits of physical activity.
Children, adults and older adults influence/ motivation towards PA behaviour
- Children -> Bone health, cognitive function, CV fitness, muscle fitness, weight status, depression
- Adults -> All-cause mortality, stroke and heart disease, hypertension, type 2 diabetes, 8 cancers, depression, cognitive function, dementia, quality of life, sleep, anxiety/depression, weight status
- Older adults -> Falls, frailty, physical function
WHO PA global plan for increasing PA behaviour
- Vision -> More active people for a healthier world
- Mission -> To ensure that all people have access to safe and enabling environments and to diverse opportunities to be physically active in their daily lives, as a means of improving individual and community health and contributing to the social, cultural and economic development of all nations
- Target -> A 15% relative reduction in the global prevalence of physical inactivity in adults and in adolescents by 2030
Outline and draw the ‘determinants rainbow’ (ecological model)
-Integration of different behavioural theories and models
-Inter-relationships between individuals and their environment – social and physical environment
-Correlates -> statistical associations – no causality
-Determinants -> longitudinal research – causal associations
Describe some determinants of PA in according to different demographics
(learning difficulties, homeless men, black people, gypsy or Irish travellers, LGBTQI+)
Identify some determinants of PA according to different demographics
(Canadian Fitness and Lifestyle Research Institute Study)
-Possible reasons for not exercising? -> Barriers. Canadian Fitness and Lifestyle Research Institute – Investigated barriers to physical activity when it conducted the 1995 Physical Activity Monitor. More than 2500 Canadians were asked ‘How important is each of the following in keeping your from maintaining physical activity?’. Those who answered ‘important’ or ‘very important’ to any of the 15 barriers included were considered to be experiencing the barrier. Found: Major barriers – lack of time (69%), lack of energy (59%), lack of motivation (52%). Time, energy, motivation, cost were the top 4 barriers for ages 18-24 and 25-44.
Explain the importance of understanding determinants of PA in different groups
-Psychological theories and models help us to understand the process of exercise adoption and adherence -> several major models/theories.
-The determinants rainbow -> PA/exercise adoption (action) and adherence (maintenance). The main psychological determinants include: lack of motivation, feeling uncomfortable, lack of skill and fear of injury (and they are all individual). Psychological determinants are however modifiable.
Outline psychological theories and models relevant to promoting PA adoption and maintenance
-Transtheoretical model
-Transtheoretical model -> Understand the stages that people go through with regards to the process of; exercise adoption, maintenance and relapse. Individuals can engage at any stage: design interventions which addresses these barriers or determinants.
-Designing interventions -> No intent to change, couch potatoes, defensive and uninformed, seriously intend to exercise?
Outline psychological theories and models relevant to promoting PA adoption and maintenance
-Self-efficacy
-Self-efficacy -> Fallon, Hausenblas and Nigg (2005). Examined whether self-efficacy to overcome barriers could distinguish between the action, maintenance, and termination stages of change for men and women. N= 330 male and 380 female (M age between 24 and 27 years). Barriers-efficacy scale: 12 items. Perceived ability to exercise 5 x per week in the face of barriers (e.g. bad weather, lack of interest/boredom, pain and discomfort, exercising alone). Stages of change questionnaire: 5 items (+1 extra for termination phase) – ‘Do you exercise 3 times a week, for at least 20 minutes each time?’. Level of SE was able to correctly classify 57% of the females according to their reported stage of change.
Outline psychological theories and models relevant to promoting PA adoption and maintenance
-Autonomous motivation
-Autonomous motivation -> Zamarripa et al., 2018. Analysed variations in behavioural regulations using the stages of change model. N = 530 participants. Pre-contemplation – external and amotivation predominated. Action and maintenance – intrinsic, integrated and identified.
* Fostering self-efficacy and autonomous motivation towards physical activity and exercise may likely have positive implications for physical activity/exercise behaviour change
* SE theory -> Higher SE for maintenance
* Self-determination theory -> More autonomous motivation for action
Describe strategies that can be used to support PA/ exercise adoption and maintenance (6 approaches)
-Need individualised strategies -> 6 broad strategies/ approaches:
1. Behavioural modification
2. Cognitive-behavioural
3. Decision making
4. Social support
5. Reinforcement
6. Intrinsic
Behavioural modification approach
Behavioural modification approaches -> The planned, systematic application of learning principles to the modification of behaviour. Examples:
* Behavioural contract -> specifies expectations and responsibilities (goals, dates, consequences)
* Prompts -> Cue that initiates a behaviour (verbal, physical, symbolic)
Kerr et al., (2001). 12-week stair climbing intervention. Banner on stair rises. Maintenance of behaviour can result to banners being removed. Compared sex/age differences -> individualized approaches.
Cognitive behavioural approach
Cognitive-behavioural approaches -> Assume internal events (i.e. thinking) have an important role in behaviour change. Examples:
* Goal setting -> Flexible, participant led (set by themselves-> autonomy), intrinsic (personal interest, improving health – rather than intrinsic)
Martin et al., (1984) – Exercise class participants. Participants set their own flexible goals. Attendance = 83% and 47% still exercising 3-months after programme. Instructor set-goals – 67% attendance and 28% exercise maintenance.
Decision making approach
Decision making approaches -> Decisional balance – cost vs benefit analysis
