Learner objectives
• Describe public policymaking using a Socio-Ecological perspective.
• Discuss how policy can influence health weight promotion at all levels of the Socio-Ecological Model.
• Review differences between public policy, institutional and organizational policies, and programs and how to create synergy across the domains.

What is public policy?
• “ A statement by government of what it
intends to do or not to do, such as law,
regulation, ruling and decision, or order, or a
combination of these” (Birkland, 2001)
• “Political decisions for implementing programs
to achieve goals” (Cochran & Malone, 1995)

Policy is government’s response to
societal problems.

Policymaking
• Policymaking is essentially a decision-making process
involving the allocation of scarce resources; it can be
conceived of as a competition
• Need to develop an understanding of:
• The particular type of decision-making
• The decision-making context, participants and
processes
“[Political] competence entails knowing how
and where to exert influence” (Longest, 2002, p. 43)

Policymaking process
• Three components:
• Policy formulation
• Implementation
• Modification
• Characteristics:
continuous, inter-related, cyclic, no
phase complete without the others.

Social Ecological Model
Effective behavior change/health
promotion must target individual and
social factors; multi-level interventions are
synergistic.

Aims
• Improve health outcomes
• Reduce disparities

Social Ecological Model

Roots
Ecology (derived from the biological sciences)
Describes the complex interrelationships
among organisms and the environment
in which they are embedded
Social Ecology
The study of the influence of the social
context on behavior, including
institutional and cultural variables (Sallis &
Owen, 2002).

Two features of the model
• Embeddedness-One
system is nested in hierarchy of other
systems at different levels of analysis
• Emergence-System at each level is
greater than the sum of its parts

Two key concepts
Multiple levels: Behavior
affects and is affected by multiple levels of influence
Reciprocal causation:
Individual behaviors
shapes, and is shaped by, the social environment (similar idea in Social Cognitive
Theory)

If social change supports individual
change, more self-sustaining.

Majority of obesity interventions address clinical, behavioral or
educational issues; little attention paid to environmental factors.

Public policy interventions
• Public policy interventions or influences can be direct or indirect:• Direct-Policy
regarding food packaging, advertising
• Indirect-Farming policy, production practices, trade agreements

Food environment
• Proximity unhealthy food choices are major driver of weight
• Disparity between cost/calorie of healthy food and energy-dense foods are growing
• Portion sizes also growing; portion size directly influences consumption
• Frequency of eating away from home growing; associated with decreases in food quality
• Marketing favors unhealthy food choices

Environmental drivers of obesity
• Humans heavily influenced by default
conditions
• Defaults are conditions people are exposed to
in day-to-day life affecting behavior and health
• Defaults in food environment can influence
selection and consumption of food
Policy interventions that change defaults are
swiftest and most effective way of producing
change

Examples of policies to change
defaults
• Safe Routes to Schools
• Let’s Move!
• Healthy Food Financing Initiative
• Healthy, Hunger-Free Kids Act
• ACA menu labelling

Three most cost-effective policy
interventions
• Tax on unhealthy food and beverages
• Traffic light nutrition labeling system
• Decreased marketing of unhealthy food and
beverages to children
(Novak & Brownell, 2012)

Challenges
Multi-level interventions are scarce; most
interventions are single-level and primarily
focused on intrapersonal change.(Scholmerich & Kawachi, 2016)

Addressing environmental defaults
• Generally fail to address most powerful
defaults:
• Marketing unhealthy foods to children
• Availability of sugary drinks
