Public Health Notes

Disease Causation and Prevention

  • Public health interventions aim to prevent disease and maximize health.
  • Interventions targeting pregnant women, babies, and young children can influence lifelong health.
  • Evaluation of interventions is crucial but can be complex.

Prevention in Early Years

  • Early interventions for children and families are evaluated based on:
    • Education
    • Health and nutrition
    • Socio-economic benefits
    • Emotional and social support
    • Combined programs
  • Preschool education improves social and intellectual development.
  • Parental education includes parenting skills and adult education access.

Health and Nutrition

  • Low birthweight (LBW) is linked to higher infant mortality and chronic conditions.
  • Modifiable factors influencing LBW:
    • Poor maternal nutrition
    • Smoking during pregnancy
  • Breastfeeding benefits:
    • Reduced infection risk
    • Lower SIDS rates
    • Reduced obesity and diabetes rates
    • Lower atopy rates
    • Mother-baby bonding
    • Reduced cancer rates in mothers
  • Interventions include education, subsidies, and supplements (e.g., fluoridation).

Socio-Economic Benefits

  • The Acheson Report highlighted poverty risks for families with young children.
  • Recommendations:
    • Accessible, affordable childcare
    • Increased benefits and uptake

Emotional/Social Support

  • Family support programs aim to:
    • Improve parental wellbeing
    • Improve child development
    • Prevent child abuse

Combined Programmes

  • These programs combine multiple intervention types, often run by multi-agency teams.
  • Examples: Sure Start (UK) and Head Start (USA).
  • The Healthy Start program provides food and vitamin vouchers for disadvantaged pregnant women and young children.
  • Family Nurse Partnership (FNP): A preventive program for vulnerable young first-time mothers offering home visits and support.

Pre-Determinants of Health

  • Pre-determinants are factors affecting the determinants of health.
  • Include material goods, policies, and societal factors.
  • Social cohesion (strong interactions, mutual support, few inequalities) improves health outcomes.

Individual Behaviour Change

  • Interventions to influence health behavior can be implemented at multiple levels.
  • Face-to-face methods:
    • Motivational interviewing: Patient-centered counseling based on the stages of change model.
    • Cognitive behavioral therapy (CBT): Replacing unhealthy behaviors with healthy ones.
  • Incentives to encourage healthy behavior:
    • Vouchers for smoking cessation
    • Financial rewards for avoiding STIs or achieving weight loss

Role of Social Marketing

  • Social marketing uses commercial marketing techniques to promote health messages.
  • Involves seven steps:
    • Identify the target group
    • Research target group
    • Competitive analysis
    • Set objectives
    • Develop the message
    • Sell the message (4 Ps)
    • Evaluate
  • The 4 Ps of marketing: product, price, placement, and promotion.

Involving the Public

  • Reasons to involve the public:
    • Improved treatment outcomes
    • Empowerment
    • Democracy
    • Integrated approaches
    • Better decisions
    • Acceptability
    • Ownership and sustainability
  • Brager and Specht described a health ladder specifying different levels of community involvement.

Deprivation and its Effect on Health

  • Deprivation (material or social) is associated with:
    • Lower life expectancy
    • Higher risk of tobacco, alcohol, and drug dependence
    • Higher chance of developing a long-term illness
  • Manifestations of deprivation:
    • Housing
    • Environment
    • Income
    • Employment
    • Education
    • Social exclusion
  • Types of poverty: absolute and relative.
  • Factors reinforcing deprivation: social exclusion, discrimination, employment, stress, and antenatal effects.

Community Development

  • Benefits and means of community development, including the roles and cultures of partner organizations.

Health Impact Assessment

  • HIA of social and other policies.

Strategic Partnerships

  • Role of strategic partnerships and the added value of organizations working together.
  • Local strategic partnerships (LSPs) encourage collaboration to address complex problems.

Setting Targets

  • Reasons for setting targets in healthcare:
    • Adoption of management practices
    • Improvement of performance and accountability
    • Ensuring consistency across services
  • Targets can relate to structure, process, output, or outcome.
  • Targets can be set at the micro(individual), meso(organizational), or macro(national) level.
  • 'SMART' targets: Specific, Measurable, Achievable, Relevant, Timescale
