systematic differences in health status between different socio-economic groups
5
Q
health literacy
A
people having the skills (language, literacy and numeracy), knowledge, understanding and confidence to access, understand, evaluate, use and navigate health and social care information and services
6
Q
two types of health behaviour models
A
- explanatory theory/ social cognition models
2. change theory
7
Q
public health
A
the health of a population as a whole, especially as the subject of government regulation and support
understanding causes of ill-health, seeking to explain and or predict health-related behaviour, helping clients, groups or communities redirect their own activities towards health and wellbeing
8
Q
health education
A
combination of learning experiences to help individuals and communities improve their health by increasing their knowledge or influencing their attitudes
part of health promotion
9
Q
what is explanatory theory
A
used to explore reasons behind a particular health behaviour by focusing on the individual
10
Q
examples of explanatory theories
A
health belief model theory of reasoned action/planned behaviour transtheoretical (stages of change) model social cognitive (learning) theory
11
Q
What is change theory
A
Theory to guide change following explanation of change needed to improve health
12
Q
health belief model (HBM)
A
desire to avoid negative health consequences
used to try and predict health behaviours
13
Q
examples of health belief models
A
condoms, seat belts, medical compliance, health screening
14
Q
6 concepts protective/health promoting actions depend on in the Health Belief Model
A
- perceived susceptibility
- perceived severity
- perceived benefits
- perceived barriers

- self-efficacy
15
Q
what is perceived susceptibility
A
belief of chances of getting a condition
16
Q
what is perceived severity
A
belief of how serious condition and consequences
17
Q
what is perceived benefits
A
belief in the efficacy of the advised action to reduce risk or seriousness of impact
18

strategies to activate ‘readiness’
20
Q
what is self-efficacy
A
confidence in ones ability to take action
21
Q
3 challenges in applying the HBM
A
- avoiding blame (HBM stresses personal responsibility)
- solutions often more complex or caused by factors over which individuals have less personal control
- challenge of providing meaningful cues to action
22
Q
theories of reasoned action and planned behaviour
A
centres on individuals attitudes and beliefs
seeks to explain behaviours under voluntary control
23
Q
Stages of change (transtheoretical) model
A
identifies 5 stages of change in behaviour representing ‘levels of readiness’
24
Q
5 stages of stages of change model
A
- pre-contemplation
- contemplation
- preparation
- action
- maintenance
- potentially relapse as 6th stage
25
social cognitive theory (SCT)
takes into account determinants of health and individual behaviours
links personal factors, behaviour and environmental influences
26
diffusion of innovations
identifies factors that influence how quickly an idea or behaviour is adopted
highlights uncertainties associated with new behaviours
27
according to diffusion of innovations, what 4 factors does the adoption of a new idea depend on
1. characteristics of the innovation
2. communication channels
3. time
4. social system
28
behavioural change wheel
developed from 19 frameworks of behaviour change and consists of 3 layers
29
3 layers of behaviour change wheel
1. 6 source of behaviour (2 in each domain)
2. domains of: opportunity, capability and motivation
3. 9 intervention functions
30
6 sources of behaviour in behaviour change wheel
```
Capability domain
1. physical
2. psychological
Opportunity domain
3. social
4. physical
Motivation domain
5. reflective
6. automatic
```
31
what is the purpose of screening
to reduce risk of certain groups in the population by identifying those more susceptible to diseases, reducing associated risks of complications
32
what is screening
process of identifying healthy people who may be at increased risk of disease or condition, enabling earlier treatment and better informed decisions
33
11 UK national population screening programmes
```
abdominal aortic aneurysm (AAA)

newborn hearing screening (NHSP)
sickle cell and thalassaemia (SCT)
```
34
screening parameters

- test (sieve or screen)
- sorting for positives (
- intervention for cases
- avoidable outcomes
35
false positive
wrongly reported as having the condition
36
false negative
wrongly reported as not having the condition
37
harm caused by false negative/positive

44
7 priorities for action to improve national health
1. tackle obesity, particularly among children
2. reduce smoking and stop children starting
3. reduce harmful drinking and alcohol related hospital admissions
4. ensure every child has best start in life
5. reduce risk of dementia, incidence and prevalence in 65-75y/o
6. tackle growth in antimicrobial resistance
7. achieving a year-on-year decline in the incidence of Tb
45
UK guidance for alcohol consumption
14 units spread over 3 days or more
46
1 unit of alcohol equivalent to...
half a pint of beer
half a small glass of wine
one single shot of spirit
47
low risk of drinking behaviour
both men and women not drinking regularly more than 14 units per week spread over 3 or more days
48
increasing risk of drinking behaviour
men - regularly drinking 15-49 units/week
women - regularly drinking 15-34 units/week
49
higher risk of drinking behaviour
men - regularly more than 8 units/day or 50+ units/week
women - regularly more than 6 units/day or 35+ units/week
50
binge drinking - risk of drinking behaviour
men - more than 8 units on heaviest drinking day in previous week
women - more than 6 units on heaviest drinking day in previous week
51
brief alcohol interventions
short, time-limited interaction/ conversation (no more than 5 mins)
guided nature of conversation, delivered in a motivational style, distinguishes it from basic information giving
52
addressing smoking (3 A's)
ASK - all patients if they smoke
ADVISE - the best way to stop (for them)
ACT - by offering referral to local stop smoking services
53
4 quitting methods for smoking
1. local stop smoking services offer best chance of success
2. using a prescribed medicine
3. using OTC nicotine replacement (patches, gum or e-cig)
4. using will power alone - least effective method
54

```
58
advise for smoking cessation pregnancy and breastfeeding
try to stop without NRT but can be used as far less risk to baby than continuing to smoke
for breastfeeding: if using NRT = should use intermittently (not patches)
59
factors that can lead to relapse
```

taken immediately before, during or up to 1 hour after a meal
if meal contains no fat - skip dose
review at 12 weeks
75
additional meds when taking orlistat
use additional contraceptive to prevent failure of oral contraception from severe diarrhoea
orlistat may impair absorption of vit A,D,E and K - consider multivitamins taken at least 2 hours after orlistat, or at bedtime
