- Prevention reduces risk before disease or complications occur.
- Education programs and campaigns are named syllabus examples.
- Strategies should target a specific risk factor and audience.
- Effectiveness must be evaluated using evidence.

Prevention Campaigns for Non-infectious Disease
Prevention strategies use evidence to reduce disease risk before treatment is needed. Learn how education programs and campaigns are designed, evaluated and improved.
Today's hook: A poster that says "be healthy" is not automatically a prevention campaign. What evidence would show that a campaign actually reduces disease risk?

Lesson map
Evidence -> strategy -> evaluation
Build a prevention strategy that is biologically targeted and evidence based.
- 1Choose the preventable risk.Use epidemiological evidence, not guesswork.
- 2Design the campaign.Match message, audience and action to the disease mechanism.
- 3Evaluate effectiveness.Use measurable outcomes and identify limitations.
Know what matters
- Campaign outcomes can include knowledge, behaviour, screening rates or disease rates.
- Good campaigns remove barriers rather than only blaming individuals.
- Secondary sources help justify the strategy and judge its impact.
- Population-level policy such as pricing, access, labelling or urban design.
- Equity, cultural safety and unintended consequences.
- Short-term campaign metrics versus long-term disease outcomes.

Put the campaign-design steps in order.
- Choose actions that reduce the barrier or risk.
- Use evidence to identify a disease and risk factor.
- Decide how effectiveness will be measured.
- Define the target audience.

Example: melanoma prevention
explainA melanoma campaign can target UV exposure by combining education with practical supports: shade, sunscreen, protective clothing and reminders when UV levels are high. Evaluation could compare sun-protection behaviour, sunburn rates or melanoma trends over time.

Worked example: campaign design
Disease and risk: melanoma; harmful UV exposure. Audience: secondary students, with attention to outdoor sport and lunchtime exposure. Actions: teach when UV protection is needed; provide shade and sunscreen; require hats or protective clothing; use UV-index reminders. Measures: observed protection behaviour, sunscreen access, reported sunburn and sustained participation. The actions target both knowledge and practical barriers.
Worked example: evaluating evidence
A rise in sunscreen use is evidence of short-term behaviour change, not direct proof that melanoma incidence has fallen. Stronger evaluation would combine several measures: observed protection behaviour, sunburn or UV-exposure data, participation across different groups, comparison with baseline or a comparison group, sustained change and long-term disease trends. Access to sunscreen and shade, cultural safety and reach to high-exposure groups determine whether the strategy is equitable.
Short Answer Model Answers
SA1 (3 marks): A one-off poster mainly provides a general message and may change knowledge without changing exposure [1]. A stronger strategy targets the biological risk, UV exposure, through education plus practical actions such as shade, sunscreen, protective clothing or a hat policy [1]. It also specifies an audience and a measurable outcome, allowing effectiveness to be evaluated rather than assumed [1].
SA2 (4 marks): The risk factor is harmful UV exposure and the target audience is school students [1]. Two linked actions could be UV-risk education and removing practical barriers by providing shade and sunscreen, supported by hats, protective clothing or UV-index reminders [2]. Effectiveness could be measured using observed protection behaviour, sunscreen use, sunburn frequency or a pre/post comparison, with the measure matched to the campaign aim [1].
SA3 (6 marks): The 30% rise supports a positive short-term change in one protective behaviour [1], so the campaign shows some effectiveness. However, sunscreen use alone does not measure total UV exposure, correct application, use of shade or protective clothing, and three months cannot demonstrate reduced melanoma incidence [2]. Further evidence should include sustained behaviour, sunburn or exposure data, baseline or comparison-group results and longer-term health trends [1]. Self-reporting and seasonal change may bias the result. Access to free sunscreen and shade, cultural suitability and reach to high-risk groups should be examined because unequal access can limit or widen the benefit [1]. Overall, the campaign is promising but the evidence is insufficient for a strong claim of melanoma prevention [1].

Return to the school melanoma example. Explain how you would improve a one-off awareness message so it targets UV exposure, removes a barrier, reaches the intended audience and produces evidence that can be evaluated.
