Size of problem: incidence / prevalence
Impact of problem: morbidity and mortality, life expectancy
Data comes from: registry, hospital admissions, GP databases, mortality data, primary data collection
Services available for the problem: prevention / treatment / care
Evidence base: effectiveness / cost-effectiveness
Models of care: incl. quality + outcome measures
Existing services: unmet need, services not needed
65

Reinforces the biomedical model
Required data may not be available
Variable data quality
Evidence base may be inadequate
Requires staff to be trained in data analysis
Does NOT consider ‘felt needs’ of people affected
66
Explain the Comparative Approach to Health Needs Assessment.
Compares services received by a population (or subgroup) with other populations, to identify variation in performance, cost and service use
> can be spatial (different towns)
> can be social (two age groups in the same town)
May examine:
Service access
Service provision
Service utilisation
Health outcomes: mortality, morbidity, QoL, Patient satisfaction
67

Asking the local population what their health needs are - structured collection of knowledge and views of the stakeholders
Use of focus groups, interviews and public meetings.
Wide variety of stakeholders, such as teachers, healthcare workers, social workers, charity workers, local businesses, council workers, politicians, patients, parents
Based on the demands, wishes and perspectives of the parties involved, and recognises the importance of their experiences.
69
List 4 problems with a corporate approach to health needs assessment
May be difficult to distinguish need from demand
Groups may have vested interests
May be influenced by political agendas
Dominant personalities may have undue influence.
70

Transtheoretical Model
Motivational interviewing
Social norms theory
Nudging (choice architecture, e.g. fruits and veg near the till)
Financial incentives
98
Explain the theory behind the Health Belief Model:
Individuals will change if they believe:
they are susceptible to the condition
that the disease has serious consequences
that taking action reduces susceptibility
that the benefits of taking action outweigh the costs.
Cues to action may also be present
99
Critique the Health Belief Model:
Alternative factors may predict health behaviour (outcome expectancy, aka whether someone feels their behaviour will make them healthier, and self efficacy)
HBM doesn’t consider the influence of emotions on behaviour
HBM doesn’t differentiate between 1st time and repeat behaviour
100
In the Health Belief Model, what has been demonstrated to be the most important factor in addressing behaviour change?
Perceived barriers have been demonstrated to be the most important factor for addressing behaviour change in patients.
101
Explain the ‘Theory of Planned Behaviour’.
Proposes the best predictor of behaviour is ‘intention’
Intention is determined by:
> a person’s attitude to the behaviour
> the perceived social pressure to undertake the behaviour, or “subjective norm”
> a person’s appraisal of their ability to perform the behaviour, or their perceived behavioural control.
102
Critique the Theory of Planned Behaviour.
Lacks direction or causality or temporal element
Doesn’t account for emotions eg. fear, threat, positive affect etc. which might disrupt ‘rational’ decision making.
Habits + routines bypass cognitive deliberation + undermine a key assumption of the model.
Relies on self-reported behaviour.
Doesn't account for the intention-behaviour gap
103
In the theory of planned behaviour, what impacts people's ability to act on their intentions?
Perceived control
Anticipated regret
Preparatory actions (dividing a task into subgoals improves behaviour)
Implementation intentions (i-then plans)
Relevance to self
104
Give 3 advantages of the transtheoretical model / ‘Stages of Change’ model:
Acknowledges individual stages of readiness (tailored interventions)
Accounts for relapse
Temporal element (although arbitrary)
105
Give 3 disadvantages of the transtheoretical model / stages of change model.
Not all people move through every stage.
Arbitrary lines are drawn between stages
- change might operator on a continuum, rather than in discrete stages
Doesn’t take into account values, habits, culture, social + economic factors
106
Summarise the transtheoretical model / stages of change model.
Examines the process of change, rather than factors that determine behaviour.
Allows for interventions to be tailored to the individual according to what stage they are at.
107
Summarise ‘Motivational Interviewing’ as a theory of behaviour change.
A counselling approach -> initiates behaviour change by resolving ambivalence.
Clinical impact has been shown in problem drinkers or substance abusers.
108
Aside from the recognised models, what factors might influence a person’s ability to change their behaviour(s)?
Impact of personality traits on health behaviour
Assessment of risk perception
Impact of past behaviour / habit
Automatic influences on health behaviour
Ability to maintain the behaviour
Social environments
109
What does the NICE guidance say about behaviour change and transition points?
Interventions to change health related behaviour should work in partnership with individuals, communities, organisations + populations.
Typical transition points include:
> leaving school
> entering the workforce
> becoming a parent

Classification of health outcomes: (the 5Ds: death, disease, disability, discomfort, dissatisfaction)
Mortality eg. 30 day mortality rate
Morbidity eg. Complication rates
Quality of life / PROMs (Patient Reported Outcome Measures)
Patient satisfaction
113
List Maxwell’s Dimensions of Quality (as applied to Quality of Healthcare). (3As and 3Es)
Effectiveness: does the intervention produce the desired effect?

116
What are some of the consequences of undernutrition?
Stunting: low height for age
Wasting: low weight for height
Underweight: low weight for age
Micronutrient deficiencies / insufficiencies -> a lack of important vitamins + minerals.
117
What are some of the consequences of being overweight?
Obesity
- Diet-related non-communicable diseases eg. Heart disease, stroke, diabetes, cancer
118
Give examples of early influences on feeding behaviour.
Maternal diet + taste preference development - amniotic fluid is influenced by maternal diet, so in utero environment influences taste exposure
Breast feeding - for taste preference + body weight regulation
Parenting practices
119
How does the maternal diet lead to early flavour exposure for the baby in utero?
Baby’s taste + olfactory systems can detect flavour information prior to birth
Amniotic fluid + human milk transmit volatiles from the maternal diet, providing early chemosensory experience.
120
How might breast feeding be considered to be a public health issue?
Prevalence of breastfeeding is particularly low among very young mothers + disadvantages socio-economic groups, potentially widening existing health inequalities.
121
What are the 3 components of breast milk?
Colostrum
Foremilk
Hindmilk
122
Describe the composition of colostrum.
High protein
Low fat
Contains lots of antibodies

Responsive feeding: recognizing hunger + fullness cues
Providing a variety of foods
Avoid pressure to eat
Not using food as a reward
Indulgent / neglectful feeding practices.
125
What is ‘chemical continuity’ with regards to feeding behaviours?

128
Define ‘disordered eating’.
Restraint, strict dieting, disinhibition, emotional eating, binge eating, night eating, weigh + shape concerns, inappropriate compensatory behaviours that do not warrant a clinical diagnosis.
129
What are the 3 basic forms of dieting?
Restrict the total amount of food eaten
Do not eat certain types of food
Avoid eating for long periods of time
130
What are the problems with dieting?
Dieting is a risk factor for developing eating disorders
Dieting results in a loss of lean body mass, not just fat mass.
ieting can be difficult to stick to - people often relapse back into unhealthy behaviours.
Dieting slows metabolic rate + energy expenditure
Chronic dieting may disrupt ‘normal’ appetite responses + increase subjective sensations of hunger.
131
Why is dieting so difficult for some patients? (cues)

Coherence – logical consistency with lab information e.g. incidence of lung cancer
with increased smoking is consistent with lab evidence that tobacco is carcinogenic
Analogy – similarity with other established cause-effect relationships in the past e.g.
thalidomide in pregnancy, not other teratogenic drugs show similar effects

Describe the physiology of addiction:
Drugs stimulate the mesolimbic pathway int he brain (reward), of which dopamine is the main neurotransmitter, giving a sense of pleasure that reinforces the behaviour. Repeated exposure to the stimulus reduces the number and sensitivity of the dopamine receptors, requiring an increasingly strong stimulus to activate them for the same reward. At the same, the reward response to everyday activities also decreases. As a result, the person increasinly seeks out the substance to trigger their reward pathway. People, places or events can trigger cravings.
