Promoting Healthy Behavior
© 2005 POPULATION REFERENCE BUREAU
Behavior and Global Health
• Physical good health eludes billions of people• Death and disease from preventable causes
remain high• Behavior is a key factor in determining health
“Health is a state of complete physical, psychological, and social well-being and not simply the absence of disease or infirmity.” (World Health Organization, 1948)

Ten Leading Risk Factorsfor Preventable Disease
• Maternal and child underweight
• Unsafe sex• High blood pressure• Tobacco• Alcohol• Unsafe water, poor
sanitation, and hygiene
• High cholesterol• Indoor smoke from solid
fuels• Iron deficiency• High body mass index
or overweight

Whose Behavior is Responsible For…
• Maternal and child underweight• Smoking and alcohol abuse • Unsafe sex • Unsafe water and lack of adequate sanitation
© 2005 POPULATION REFERENCE BUREAU
Maternal and Child Underweight
• Individuals (may resist nutrition education)• Communities (male preference norms)• Policymakers (fail to address poverty)• Health planners and health workers (do not
include nutrition programs for the poor)
© 2005 POPULATION REFERENCE BUREAU
Smoking and Alcohol Abuse
• Individuals (choice)
• Communities (norms regarding smoking)
• Health policymakers
• Legislators & tax assessors
• Tobacco company executives
• Decision-makers in marketing companies

Unsafe Sex
• Individuals (abstinence, fidelity, condoms)
• Communities (norms regarding male
dominance and multiple partners)
• Poverty (transactional sex for poor women)
• Health policymakers and health workers
(effective AIDS prevention programs)

Unsafe Water and Lack of Adequate Sanitation
• Individuals (where they fetch water, boiling
water, washing hands)
• Communities (fatalism regarding diarrheal
diseases, community latrines)
• Governments (ignore or underfund safe water
and sanitation needs)

Health Promotion Means Changing Behavior at Multiple Levels
A Individual: knowledge, attitudes, beliefs, personality
B Interpersonal: family, friends, peers C Community: social networks, standards,
norms D Institutional: rules, policies, informal
structuresE Public Policy: local policies related to
healthy practices

A: Individual-Oriented Models
• Individual most basic unit of health promotion• Individual-level models components of
broader-level theories and approaches • Models
Stages of Change Model Health Belief Model

Stages of Change Model
• Changing one’s behavior is a process, not an event
• Individuals at different levels of change• Gear interventions to level of change

Health Belief Model
• Perceived susceptibility and severity of ill health
• Perceived benefits and barriers to action• Cues to action• Self-efficacy

B: Interpersonal Level:Social Learning Theory
• Interaction of individual factors, social environment, and experience
• Reciprocal dynamic• Observational learning• Capability of performing desired behavior• Perception of self-efficacy

Interpersonal Level:Social Learning Theory (cont.)• Three strategies for increasing self-efficacy
Setting small, incremental goals Behavioral contracting: specifying goals and
rewards Self-monitoring: feedback can reinforce
determination to change (keep a diary)
• Positive reinforcement: encouragement helps

C: Community-Level Models
• Analyze how social systems function• Mobilize communities, organizations, and
policymakers• Use sound conceptual frameworks
Community Mobilization Organizational Change Diffusion of Innovations Theory

Community Mobilization
• Encompasses wider social and political contexts
• Community members assess health risks, take action
• Encourages empowerment, building on cultural strengths and involving disenfranchised groups

Diffusion of Innovations Theory• How new ideas, products, and behaviors
become norms• All levels: individual, interpersonal,
community, and organizational• Success determined by: nature of innovation,
communication channels, adoption time, social system

Diffusion of Innovations (cont.)
Nature of innovation• Relative advantage over what is being
replaced• Compatible with values of intended users• Easy to use• Opportunity to try innovation • Tangible benefits
© 2005 POPULATION REFERENCE BUREAU
Diffusion of Innovations (cont.)
Communication channels• Mass media (enhanced by listening groups,
call-in opportunities, and face-to-face approaches)
• Peers• Respected leaders

Diffusion of Innovations (cont.)
Adoption time• Awareness Intention Adoption Change• Gradual• Movement through groups
Pioneers Early adopters Masses

Diffusion of Innovations (cont.)
Social system:• Identify influential networks to diffuse
innovation: health systems, schools, religious and political groups, social clubs, unions, and informal associations
• Identify opinion leaders, peers, and targeted media channels to diffuse innovations

Behavior Change Successes
• Reducing malnutrition (micronutrient initiatives)• Preventing malaria (insecticide-treated bednets)• Helping children survive (breastfeeding)• Improving maternal health (safe motherhood
movement, emergency obstetric care)• Making family planning a norm (worldwide efforts)• Combating HIV/AIDS (Uganda program)

Combating HIV/AIDS in Uganda
• Political support, multisectoral response• Decentralized behavior change campaigns• Focus on women and youth, stigma and
discrimination• Mobilization of religious leaders• Confidential voluntary counseling and testing• Social marketing of condoms• Control and prevention of STIs

Health Promotion: Lessons Learned
• Research underlying causes• Address contextual factors• Identify and reach key actors at every level• Involve stakeholders throughout process• Use sound behavioral theories
• Monitor and evaluate
© 2005 POPULATION REFERENCE BUREAU
Conclusion
• Improving global health requires behavior change at every level—individuals, families, communities, organizations, and policymaking bodies
• Evidence-based behavioral theories and successful behavior-change case histories point the way
• Next step: political will and sufficient resources
