Research on School Wellness Policies
Written Policy
Implementation
– 99% of school districts wrote
a policy
– Barriers: time, people,
incentives, resources
– Language is weak
– Increased nutrition education
– Variety of policy components
– Fewer sugar sweetened
beverages
– Adolescents in school districts
with mandated wellness
policies may have lower BMI
– No change in physical
education or activity
– No studies with BMI
Adolescent obesity rates vary by
community
Social, economic, behavioral and cultural factors
influence adolescent BMI

School Characteristics and Wellness Practices
• The following were not associated with wellness
practices:
–
–
–
–
Race and ethnicity of school population
School enrollment
Rurality
Proportion of students receiving free and reduced
price meals
– Mandated policy versus recommended policy
– Practices in schools within the same district
Strengths and Limitations
Strengths
• Adds to scarce literature
• Profiles allowed
examination of practices pre
and post CNRA without lag
time
• Able to look at the same
schools over multiple time
periods
Limitations
• Profiles survey inadequate
for examining wellness
policies
• No information on school
cafeterias
• Principals may not be best
source of competitive foods
and PE practices
• Limited to one state
Summary
• Few changes in high school nutrition and physical activity practices
post CNRA
• No associations of practices by:
– School characteristics
– School district wellness policy content
– Schools in the same district
• In Utah:
– Junk foods are available in >90% of high schools
– 67% of high schools allow exemption from PE for at least one reason
– Nutrition and PA concepts are consistently taught in the health
classroom
Discussion
Research
•
•
•
Assess practices pre- and post CNRA
2010
– develop better tools for wellness
policy implementation and
evaluation
– evaluate middle school practices
Include built environment surrounding
schools in analyses
Strive to understand changes in health
behaviors and outcomes resulting from
wellness policies
Public Health Application
•
Policy is different than practice
–
–
In state policy
In federal policy
•
Ensure quality nutrition and physical
activity education in health classes
•
Do a better job with obesity
prevention in high schools
– Competitive foods/ PE
– Make guidelines specific
– Work towards long-term
sustainability
