❤️ What is Health Promotion & Disease Prevention? And Why Bother?
📖 Core Concepts & Definitions
The Problem We're Solving
In medicine, too many of us get bogged down with treating actual disease when it happens that we forget to prevent it in the first place (disease prevention). And often, we are so concerned with getting those medically unstable to a stable position that we forget about those who are stable but will go back to being unstable and develop other disease processes if we don't help them to look after THEIR OWN HEALTH CONDITION (health promotion & further disease prevention).
📈 Health Promotion (WHO Definition)
"The process of enabling people to increase control over, and to improve, their health. It moves beyond a focus on individual behavior towards a wide range of social and environmental interventions."
Aims to engage and empower individuals and communities to choose healthy behaviors, and make changes that reduce the risk of developing chronic diseases and other morbidities.
🛡️ Disease Prevention
Focuses on specific efforts aimed at reducing the development and severity of chronic diseases and other morbidities.
More targeted than health promotion - specific interventions to prevent particular diseases or conditions.
🏃 Wellness
The attitudes and active decisions made by an individual that contribute to positive health behaviors and outcomes. Health promotion and disease prevention programs often address social determinants of health, which influence modifiable risk behaviors such as tobacco use, poor eating habits, and lack of physical activity.
🎯 Primary, Secondary & Tertiary Prevention
Primary Prevention: Prevent Disease Before It Occurs
Aims to prevent disease before it ever occurs by preventing exposures to hazards, altering unhealthy behaviors, and increasing resistance to disease.
- • Immunising people (increasing resistance)
- • Statin in high QRISK patients with no PMH of IHD
- • Smoking cessation programmes
- • Healthy eating campaigns
- • Exercise promotion
- • Safety equipment (helmets, seatbelts)
- • Lifestyle counselling
- • Vaccination programmes
- • Risk factor modification
- • Health education
- • Environmental health advice
Secondary Prevention: Reduce Impact of Existing Disease
Aims to reduce the impact of disease that has already occurred by detecting and treating disease as soon as possible to halt or slow its progress.
- • Mammography to detect breast cancer early
- • Clopidogrel for patients who've had a stroke
- • Low dose aspirin after MI
- • Cervical screening
- • Bowel cancer screening
- • Blood pressure monitoring
- • Screening programme delivery
- • Early detection of disease
- • Prompt treatment initiation
- • Risk stratification
- • Follow-up and monitoring
Tertiary Prevention: Soften Impact of Ongoing Illness
Aims to soften the impact of ongoing illness that has lasting effects by helping people manage long-term, complex health problems to improve function, quality of life, and life expectancy.
- • Cardiac rehabilitation programmes
- • Stroke rehabilitation
- • Chronic disease management (diabetes, arthritis)
- • Depression support programmes
- • Palliative care
- • Disability support services
- • Chronic disease reviews
- • Symptom management
- • Referral to rehabilitation
- • Quality of life optimization
- • Multidisciplinary coordination
💡 Worked Example: The Swimming Hole Rash Outbreak
Scenario
You're the Public Health Consultant of a town near a swimming hole used by kids and adults. One summer, citizens develop serious and persistent rashes after swimming due to a chemical irritant in the river. You decide to take action.
🛡️ Primary Prevention
Action: Approach the company upstream discharging the chemical and make it stop.
Result: Remove hazardous exposure, prevent rashes in the first place. Most effective intervention - "upstream" approach.
👁️ Secondary Prevention
Action: Ask lifeguards to check swimmers for signs of rash that can be treated immediately.
Result: Not preventing rashes, but reducing impact by early treatment so swimmers recover quickly.
🤝 Tertiary Prevention
Action: Set up programmes and support groups teaching people to live with persistent rashes.
Result: Not preventing or treating rashes, but softening impact by helping people cope as best as possible.
Key Learning Point
For many health problems, a combination of primary, secondary and tertiary interventions are needed. However, prevention experts say that the further "upstream" one is from a negative health outcome, the likelier it is that any intervention will be effective.
⭐ Beyond the Obvious: Innovative Health Promotion Activities
Think Broader Than Just Lifestyle
It's not just about stopping smoking, not doing drugs, getting fitter, not drinking alcohol much and eating more healthily. There are lots of other types of health promotion and disease prevention activities. Don't limit your mind – you might come up with something innovative and transformative.

✅ Key Questions for Data Gathering
⚠️ Red Flags – What Not to Miss!
📈 Health Improvement
👥 Social Determinants of Health & Health Inequalities
WHO Definition
"The conditions in which people are born, grow, live, work and age, and people's access to power, money and resources"
⚖️ Tudor Hart's Inverse Care Law (1971)
"The availability of good medical care tends to vary inversely with the need for it in the population served"
- • Disadvantaged populations need more healthcare but receive less
- • Operates more completely where healthcare exposed to market forces
- • Still relevant today - commercial medicine excludes those who can't pay
Key Social Determinants
GP Actions to Address Health Inequalities
- • Individual level: Flexible appointments, proactive case-finding, social prescribing
- • Practice level: Targeted outreach, health promotion in deprived areas
- • System level: Advocacy for policy change, highlighting service gaps
- • Data collection: Code social determinants to enable population monitoring
❤️ Lifestyle Factors & Evidence Base
Evidence Base
- • Mediterranean diet reduces CVD risk by 30% (PREDIMED trial)
- • 5-a-day fruit/veg reduces all-cause mortality by 5% per portion
- • Processed meat increases colorectal cancer risk by 18% per 50g/day
- • High salt intake (>6g/day) increases stroke risk by 23%
GP Advice
"Aim for a plate that's half vegetables, quarter lean protein, quarter wholegrains. Small changes like swapping white bread for brown can make a big difference over time."
Evidence Base
- • 150 mins moderate activity/week reduces CVD mortality by 35%
- • Regular exercise reduces depression risk by 26%
- • Physical activity prevents 1 in 6 deaths globally
- • Even 10 mins daily walking reduces all-cause mortality by 15%
GP Advice
"Start with what you can manage - even parking further away or taking stairs counts. The best exercise is the one you'll actually do regularly."
Evidence Base
- • <6 hours sleep increases CVD risk by 48%
- • Poor sleep quality doubles depression risk
- • Sleep deprivation impairs immune function by 70%
- • Shift work increases cancer risk by 8%
GP Advice
"Aim for 7-9 hours nightly. Good sleep hygiene: regular bedtime, cool dark room, no screens 1 hour before bed, avoid caffeine after 2pm."
Evidence Base
- • Smoking reduces life expectancy by 10 years on average
- • Quitting by 40 reduces excess death risk by 90%
- • NRT doubles quit rates vs willpower alone
- • Brief GP advice increases quit rates by 66%
GP Advice

Evidence Base
- • No safe level of alcohol consumption (Global Burden of Disease)
- • 14 units/week increases cancer risk by 6%
- • Binge drinking (>6 units) increases stroke risk by 62%
- • Brief interventions reduce consumption by 13%
GP Advice
"UK guidelines: max 14 units/week spread over 3+ days with alcohol-free days. 1 unit = half pint beer, small wine, single spirit."
Evidence Base
- • Cannabis use increases psychosis risk 3-fold
- • Cocaine use increases stroke risk by 6.5-fold
- • Injecting drug use: 15x higher mortality rate
- • Harm reduction approaches reduce overdose deaths by 37%

✈️ Migration & Conflict
Displacement, trauma, interrupted healthcare, infectious disease spread, mental health impacts, social determinant disruption.
👥 Global Workforce
Healthcare brain drain, occupational health standards, migrant worker exploitation, global health security.
🛡️ Health Protection
👁️ Screening Programmes
Wilson & Jungner Criteria (1968) - Still Relevant Today
- 1. Important health problem
- 2. Natural history understood
- 3. Recognisable early stage
- 4. Suitable test available
- 5. Test acceptable to population
- 6. Intervals for repeat testing known
- 7. Effective treatment available
- 8. Agreed policy on who to treat
- 9. Facilities for diagnosis/treatment
- 10. Cost-effective
Cancer Screening
- • Cervical: 25-64 years, 3-5 yearly
- • Breast: 50-70 years, 3 yearly mammography

Risk-Benefit Discussions
- • Benefits: Early detection, improved outcomes, peace of mind
- • Harms: False positives, over-diagnosis, anxiety, radiation exposure
- • Informed consent: Must understand both benefits and harms
- • Right to refuse: Respect patient autonomy
Example: Breast Screening
"For every 1000 women screened for 20 years: 8-10 breast cancer deaths prevented, but 100-200 false alarms and 3-5 over-diagnosed cancers treated unnecessarily."
Why Screening Matters
- • Detects disease before symptoms appear
