Strategies of Health Promotion

Based on your notes and reinforced by Park's Textbook of Preventive and Social Medicine, health promotion strategies are organized along two main axes: focus (individual vs. population) and approach (medical, behavioral, socio-environmental). Here is a full breakdown:

Overview

The Ottawa Charter (1986) defines health promotion as "the process of enabling people to increase control over, and to improve, their health." It is not directed against any single disease but strengthens the host through a variety of interventions.

The strategies can be mapped on a spectrum:

Individual ←————————————————→ Population Focus
     ↕
Medical → Behavioral → Socio-Environmental Approach

I. By Population Focus

1. Individual Focus

Strategies aimed at changing the knowledge, attitudes, and behavior of a single person:

Screening - early detection of disease before symptoms appear (e.g., cervical smear, blood pressure checks)
Immunization - protecting the individual against specific infections
Risk assessment - identifying personal risk factors (e.g., family history, lifestyle habits)
Health education - giving the individual accurate health information to support informed decisions

2. Healing Communities

Strategies directed at groups or communities:

Healthy environments - improving housing, sanitation, water supply
Healthy communities & societies - building social capital, community cohesion, and peer support networks

II. By Approach (The Three Core Strategies)

A. Medical Approach

Focuses on the individual's physical health and clinical risk factors. Targets people who are unwell or at risk of disease.

Targets:

Individuals at risk of a health problem
Those who influence individuals at risk (e.g., parents who smoke in the home - risk for asthma in children)
Those who set policy

Activities include:

Screening programmes
Immunization
Risk factor management (e.g., hypertension, diabetes)

Example from your notes: A genetic predisposition to asthma means a teenager may already have it - the medical approach involves identifying and managing this early.

Limitations:

Inadequate treatment
Refusal to use an inhaler
Personal behavioral and compliance issues
Environmental factors outside clinical control

B. Behavioral Approach

Focuses on changing the lifestyle and behavior of individuals and groups. Targets habits, decisions, and self-care.

Key interventions (per Park's):

Health Education - the most cost-effective intervention; informs the public, patients, priority groups, and community leaders. WHO states: "the extension to all people of the benefits of medical knowledge is essential to the fullest attainment of health."
Nutritional Interventions - food distribution, child feeding programmes, food fortification, nutrition education
Lifestyle and Behavioral Change - encouraging smoking cessation, physical activity, safe sexual behavior; the physician acts as an educator, not just a therapist

Targets of health promotion (behavioral):

Individuals at risk of a health problem
Those who influence individuals at risk
Those who set health policy

C. Socio-Environmental Approach

The broadest strategy - focuses on the social, economic, and environmental determinants of health at a population level.

Key interventions:

Environmental modifications - safe water supply, sanitary latrines, insect/rodent control, improved housing. Many infectious diseases in Western countries were controlled through environmental changes before vaccines were even available.
Social marketing - using marketing techniques to promote health behavior across populations
Organizational development - building institutional capacity for health
Economic and regulatory activities - taxation on tobacco/alcohol, food labeling laws, occupational health regulation

Focus on: Healing communities, healthy environments, and healthy societies.

III. Ottawa Charter's 5 Key Action Areas

Park's textbook explicitly links these to the strategies above:

Action Area	Meaning
Build healthy public policy	Laws, regulations, and fiscal policies that support health
Create supportive environments	Safe physical and social settings
Strengthen community action	Empowering communities to set priorities and make decisions
Develop personal skills	Health education and life skills
Re-orient health services	Shifting focus from treatment to prevention and promotion

IV. Core Interventions Summary (Park's Classification)

Intervention	Description
Health education	Inform and empower individuals and communities
Environmental modification	Safe water, sanitation, housing, pollution control
Nutritional interventions	Supplementation, fortification, food programs
Lifestyle & behavioral change	Smoking, diet, exercise, sexual behavior

Key Point

A well-designed health promotion program must:

Identify target groups (at-risk individuals) in the population
Direct appropriate messages to them
Use organizational, political, social, and economic interventions to facilitate environmental and behavioral adaptations - Park's Textbook of Preventive and Social Medicine, p. 54

The three strategies (medical, behavioral, socio-environmental) are complementary - the most effective programs use all three together, addressing the individual, the community, and the wider determinants of health simultaneously.
