7. Using a Systems-Oriented Approach
• Developing an understanding of the whole system is a critical
first step in tackling the problem more effectively
• A systems perspective recognizes that a
complex, reciprocal, interdependent, and interactive
relationship exists between individuals and their environment
• The complex, multifaceted etiology of obesity necessitates
comprehensive systematic approaches to obesity prevention
• Highlights the importance of the circumstances in which an
event occurs (the context), in order to understand the
potential implementation and impact
• Maps out the processes and mechanisms that are needed to
change and alter the social relations that are damaging to
health

8. The Dynamics of Community Change:
The Shape Up Somerville Experience
• To describe the key aspects and dynamics of social
change within the community of Somerville over 10 years
• Retrospective examination of the SUS model using a
systems perspective in an effort to create a framework
that may help guide future community-based childhood
obesity prevention interventions
– qualitative systems analysis informed by individual and
group interviews with key SUS stakeholders and researchers
• To illustrate through the integration of the socioecological model (determinants) and community-based
participatory research methods (approach) by visualizing
the process using a systems perspective (process).

23. Evaluating Impact
OBJECTIVE:
Gain understanding of PE/PA
environment before / after ASAP program
implementation
STUDY DESIGN:
• Survey among all 1000 ASAP schools: baseline,
mid-course, year-end
• Physical Activity questions related to:
• Support / Policy
• Opportunities / # minutes/day
• PE teacher professional development
• Implementation of ASAP program
• Student fitness assessment

24. Evaluating Impact
OBJECTIVE:
• Evaluate impact 100 Mile Club & Just Move have
on school-time & daily MVPA
STUDY DESIGN:
• 6 100 Mile Club, 6 Just Move & 6 control schools
• 20-40 students/school (grades 3-5)
• Two evaluation periods: Fall ‘13 & Spring ’14
• Height/Weight
• Accelerometry (7 days)
• MCAS scores (May ‘13 & May ‘14)
