It’s been two decades since the Arnold School’s Office for Research established the
Center for Applied Research and Evaluation (CARE). Directed by Pamela Gillam, CARE’s expertise in helping partners improve their public health practices and systems
across South Carolina has resulted in a reputation as problem solvers who bring stakeholders
and specialists together.
When the Green Heart Project approached CARE to help them determine if their work was making a difference, CARE
helped them navigate the process of finding answers. Specifically, the nonprofit organization
wanted to determine if their Farm to School Program was having an impact on young
students at schools in the Charleston area.
Were their school gardens and urban farms effective tools in teaching and connecting
students to food, health, culture and the environment?
Established at a Title I school in a food desert to help students reconnect students
with fresh, local produce in 2009, the Green Heart Project now reaches nearly 3,000
students across 18 schools each year. After more than a decade of growth and engagement
it was time to assess its principal program, which takes students through the process
of growing and maintaining edible crops as well and harvesting, cooking and eating
them.
They needed both evaluation and environmental expertise to answer their questions.
Affiliates of the Arnold School’s Ph.D. in Environmental Health Sciences (ENHS) program, CARE research associates Maria McClam (alumna) and Lesley Leake (current student) led the process in identifying grant opportunities to fund the
evaluation.
They applied for and received a grant from a center for children's environmental health.
ENHS professor Dwayne Porter served as principal investigator on the study – completing a three-way partnership
to assess the program.
“Both Lesley and I have interests that intersect the environment and health,” McClam
says. “CARE collaborates well with departments like ENHS due to the wide array of
expertise and experience we all bring to the table. The Center operates with flexibility
to handle a wide variety of needs, mixed methods research approaches, and community
engaged/practical work.”
With funding in place, the team designed a case control study to be piloted at one
of the participating schools. They also conducted a cross sectional analysis of survey
responses collected by the Green Heart Project between 2017 and 2023. The collected
data includes 24-hour food diaries/recall interviews, parent demographic surveys,
rich picture activities and pre- and post-intervention surveys.
Their findings revealed an overall positive effect of the Farm to School Program on
students. Outcomes included increased fruit and vegetable consumption and improved
positive attitudes and behaviors toward heathy eating. The research team also found
a bigger impact on students from low-income schools compared to high-income schools.
“Our findings, consistent with research in the field, suggest that the Green Heart
Project’s Farm to School Program improves student’s mental model of healthy food and
the environment as well as their attitudes and behaviors towards fruits and vegetables,”
CARE concluded in the report, which precedes three manuscripts in preparation for
scientific publications that expand on these results. “Overall, the Green Heart Project
is an effective and important program for students to receive in that it has a positive
impact on their understanding of health in relation to food and the environment, especially
for students attending low-income schools.”
