Improving the school health environment through community based participatory research

1. Introduction/Importance; Goals
This pilot program will analyze the diet and exercise environments among St. Louis area schools through
participatory research techniques involving 5th and 6th grade students, teachers and administrators. It will
be coupled with education and student involvement in improving the health environments at their schools.
Long term outcomes will focus on whether this project leads to improved health environments and health
outcomes at participating schools. In developing this project I have been working with a pediatric
endocrinologist at St. Louis Children’s Hospital and the head of the Barnes-Jewish Hospital Foundation’s
(BJH) health education outreach program.

Childhood obesity is a major health problem in America with 16% of children overweight 1 and nine
million children over age six obese 2. While this epidemic affects all demographic groups, research
conducted at Johns Hopkins Bloomberg School of Public Health found large differences in obesity rates
related to socioeconomic status and race. These growing differences will likely exacerbate existing healthy
inequities found in the local community. In St. Louis, African-Americans die from the complications of
diabetes at a rate 1.7 times higher than whites 3. If trends in obesity rates continue, this inequality and
others will worsen.

Numerous groups including the Institute of Medicine2 have made specific recommendations for school
districts to implement changes which could lead to improved health among students. Several researchers
have used ideas taken from these recommendations to create “report cards” for school districts 4, 5. We are
currently in the process of developing a set of criteria based upon the Alliance for a Healthier Generation
(AHG) school wellness checklist since the district is going to use this program next year.

Although there are clearly serious deficiencies in the current system, there is reason to believe that
interventions on the school food environment can significantly impact the food consumption patterns of
students. The relative availability of different types of foods strongly affects consumption patterns 6. This
conclusion taken from a study taking a city-wide geographic approach can also be applied to the high
school food environment as shown by a study looking at disadvantaged Scottish teens 7. More direct
evidence for the efficacy of interventions comes from looking at a statewide effort to change nutrition
policy in Texas schools. Outcomes analysis showed improvements in healthy food consumption behavior
among schoolchildren after statewide policy implementation8.

The process for achieving change may come through various mechanisms. As opposed to a traditional
approach, community based participatory research (CBPR) has the capacity to integrate community
members into the process of formulating research design and implementation. CBPR has become an
increasingly popular model to conduct public health research, and has been successfully used in the past to
look at inequalities in the food environment 9.

CBPR is particularly well suited to studying the food and exercise environment since the potential solutions
can only succeed if they reflect the tastes and values of the community. This particular project aims to
increase student awareness, understanding and interest in the health environment and inequalities within
our community. The students will then assist in creating evaluation methods and proceed to evaluate their
own school environment and dialogue with their school administration and local decision-makers about
changes which would improve the school environment. The students’ suggestions will form the basis for
the School Wellness Committee which is likely to be mandated by the district at every school by next fall.

2. Methods
Participating schools will be recruited from St. Louis City. For the first year’s pilot project we plan to
involve 4 schools which already have a relationship with the BJH Foundation. In order to participate, a
school administrator and 5th or 6th grade teacher must meet with the research team, and sign a form which
explains the project, permits the research and creates a commitment to participate for at least 1 year.
SEASAW plans to contract with the BJH Foundation to provide teacher/research assistants at $75/hour of
classroom time. They have agreed to help us develop the physical curriculum free of charge. Once this is
completed by early June, we plan to present it to the Washington University IRB.

At least two weeks prior to the curriculum, the school nurse will weigh and measure each child in a private,
confidential setting. This is already being done at all city schools by school nurses, but we will need to
make sure that the measurements are done in a timely manner. The data collected will be the property of
the school and will only be shared with the researchers in de-identified form. The teacher will also provide
the researchers with de-identified demographic information on the class including gender, age and race. A
letter about the project will be sent to all parents, and will solicit involvement.

The curriculum entails 6 sessions. These classes will occur either during after school enrichment classes or
regular classroom time, but will not take away from scheduled PE. A research assistant will conduct the
curriculum along with the regular teacher.

The Healthy Youth Project (HYP) in St. Louis is currently formulating policy for the St. Louis School
District, and is recommending that every school create a Wellness Committee along the guidelines of the
Alliance for a Healthier Generation. After we presented this project at the HYP meeting in early March,
we are now reassured that the students’ recommendations will be very useful to spark action from these
committees. The researchers will visit the school at 6 months in order to personally re-evaluate the school
using the same criteria. Our program will create an incentive for positive change by recognizing successful
schools with a plaque and a $150 donation toward equipment for physical education given 6 months after
the initial program.

Primary outcomes analysis of the pilot project will include each school’s initial score on the criteria scale
and the BMI of the students. We plan to track the school’s score over several years and analyze whether
this program leads to positive changes and whether these changes relate to the average BMI of the children.
We also plan to scale up based upon our initial findings, feedback and successes.
