Q

3 levels of disease prevention strategy

A

Primary - work before biological onset - reduces incidence/prevalence by controlling causes and risk factors, e.g vaccination
Secondary - early detection to prevent more serious consequences of disease, reduces prevalence, e.g screening
Tertiary - after clinical diagnosis, reduce complications of established disease, e.g rehabilitation

A

likelihood of a positive test in those with the disease (can test identify correctly those who have disease from all individuals with it): true positives/all with disease x 100

Q

NPV and PPV

A

NPV and PPV change to reflect prevalence, if prevalence is high = higher false negative, if prevalence is low = higher false positive

Q

criteria for health prioritisation

A
  1. evidence based measures
    - descriptive evidence - what problem
    - explanatoy evidence - why (determinants, risks, why trend?)
    - evaluative - what improves outcomes and in whole (intervention
  2. community expectation - acceptability and what they want
  3. Te tiriti, human rights, social justice

Q

population attributable risk

A

the amount of extra disease attributable to a risk factor in a particular population (when association is causal, this si the amount we could prevent if we removed the risk factor from this pop.) occurance in tot. Pop. (PGO) - CGO. directly related to the prevalence of risk factor within population

Q

reasons for Global burden of disease project

A
  • Data on disease burdern was incomplete
  • Largely mortality based
  • Lobby groups give distorted image of what problems are most important
  • Unless the same approach is used to estimate burden of diseases, it is difficult to priorities what conditions are most important
17
Q

Aims of GBD

A
  • Use a systematic approach to summarise the burden of diseases at the pop. level, based on epidemiological principles and best evidence
  • Take account of deaths and non-fatal outcomes when estimating burden
18
Q

Gains of daly

A
  • Has been able to identify risk due to non-fatal diseases like mental health and injuries
  • Recognises non-communicable diseases as a major and increasing problem in low and middle income countries - not just rich ones
19
Q

challenges with GBD

A
  • Who gets to decide on disability weights? Is it biased
  • Is it reasonable to apply one set of disability weights globally
  • do all people with a particular level of disability have the same opportunities in society
  • Physical and social environment influence disability experiences
  • Represents people with disabilities as a burden
  • Disability weights do not very with the context that a person with a disability exits in
    It takes a medical model to disability
20
Q

medical model of disability

A
  • The disabled are a burden and need to be cured
  • They are the problem, not society
  • Control rest with professionals so choices and options provided rest with the expert
21
Q

Social model of disability

A
  • Problem is with the policies and environment
  • Focus on ridding society of barriers rather than relying on curing
22
Q

why policy interventions are difficult to implement

A
  • industry opposition
  • Government reluctance to regulate/tax/fund
  • Lack of sufficient public demand for policies
23
Q

epidemiological transition

A

Characteristic shift in common causes of death and disability from perinatal and communicable (infectious) diseases to non-communicable (chronic) diseases

24
Q

Risk transition

A

changes in risks factor profiles as countries shift from low-to higher income countries where common risks for perinatal and communicable diseases are replaced by non-communicable disease risks (e.g unclean water becomes tobacco)

25
Q

double burden of disease

A

in many middle income countries previously common risks for perinatal and communicable diseases coexist with increasing risks for non-communicable diseases

26
Q

industrial epidemics

A

Diseases arising from over- consumption of unhealthy commercial products (e.g. tobacco, alcohol, processed food, sugar-sweetened beverages)

27
Q

To address the commercial determinants of NCDs and health inequalities:

A
  • Shift focus from individual behaviours to broader environment and upstream drivers of unhealthy product consumption
  • Tackle the broader determinants of health(i.e.,upstream determinants)
  • Develop effective health policy recognising the tension between commercial and health objectives
28
Q

surveilance

A

continuous systematic collection, analysis and interpretation of health-related data

29
Q

three essential channels for effective communications

A
  1. Channels - relevant, accessible, trustworthy
  2. Message - appropriate, co-designed, tested
  3. Messenger - trusted credible
30
Q

feminisation of HIV epidemic

A

refers to the observation that increasing proportions of new infections are among women, primarily due to heterosexual transmission of the infection

31
Q

right to health

A
  • States obliged to respect (e.g. no discrimination), protect (e.g. no interference from 3rd parties) and fulfil (e.g. adopt measures to achieve equity)
  • enshrined in international law
32
Q

snowflake hypothesis

A

overprotection from parents and therefore low resilience leading to mental distress

33
Q

igen hypothesis

A

mediating factors from social media leading to mental health issues. Perfectionism, racism+discrimination

34
Q

doomer hypothesis

A

impact of job insecurities, housing affordability, climate, political polarisation, disinformation
