We acknowledge the Whadjuk people
of the Nyungar nation on whose land we are
gathered and pay our respects to
elders past and present.
As representatives of Curtin University we are proud to honour the Nyungar people and value this
place of shared learning. We recognise the impacts of colonisation on Indigenous Australians and as
active participants in reconciliation we are committed to moving forward together in a spirit of mutual
honour and respect.

•Notice the different levels of prevention (primary, secondary, tertiary, primordial)
•Consider when universal vs. targeted approaches are used
•Identify examples of the prevention paradox in action
•Compare behavioural and structural prevention strategies
•Think about how equity and access appear across different programs

Levels of Prevention and their Applications:
•Different levels of prevention serve complementary purposes in a
comprehensive public health strategy.
•Primary prevention focuses on preventing disease before it occurs,
secondary prevention aims to reduce impact through early detection, and
tertiary prevention aims to soften the impact of ongoing illness or injury.
Universal vs. Targeted Approaches:
•The choice between universal and targeted interventions involves complex
trade-offs between reach, efficiency, and stigmatisation.
•Universal interventions reach entire populations regardless of risk status,
while targeted interventions focus resources on those at higher risk, each
with distinct advantages and limitations.
The Prevention Paradox:
•Population-wide prevention often delivers greatest total benefit while
providing minimal benefit to individuals.
•A preventive measure that brings large benefits to the community offers little
to each participating individual.

Equity and Access in Prevention Programs:
•Prevention programs can unintentionally widen health inequalities if not
designed with equity focus.
•Without explicit attention to equity, prevention programs (i.e. screening)
tend to be utilised more by the socially advantaged, potentially widening
health disparities.
Behavioural vs. Structural Approaches:
•Most effective prevention combines individual behaviour change with
structural environmental modifications.
•Focusing solely on individual behaviour change without addressing
structural determinants often yields limited and inequitable results.
Evaluation Challenges and Program Evolution:
•Prevention program evaluation faces unique challenges including time
horizons, attribution, and evolving contexts.
•Evaluating prevention is challenging as benefits often emerge years after
implementation and multiple factors influence outcomes.

1.How do the presentations demonstrate the different levels of
prevention (primary, secondary, tertiary, primordial)? Which
level seems most emphasised in Australian public health
approaches?
2.When is a universal approach more appropriate than a
targeted approach? How do the case studies illustrate this
choice?
3.Where did you see examples of the prevention paradox in the
presentations?
4.What common barriers to equitable access appeared across
multiple prevention programs? What strategies worked to
improve equity?
5.How do successful prevention programs balance individual
behavioural approaches with structural or environmental
changes?
Consider the following:

•Differentiate between primary,
secondary and tertiary prevention
approaches.
•Discuss the role of universal and
targeted/selective approaches to
prevention.

Next Week:
Health Promotion
Next week we focus on why behaviour change is complex and effective
approaches to promoting health involve empowering communities and
individuals to take control of the determinants of their health.
