School level items
- “Does your school have a garden (vegetable
and/ or fruit) that students participate in?”
- School funding
- Co-educational/ single sex
- School size
- School decile

SLIDE 10
Analysis
- Multilevel regression models used to estimate
the association between presence of school garden and student nutrition indicators
- Analyses control for student characteristics
(sex, age, ethnicity, socioeconomics) and school characteristics (size, funding, decile)

Summary
- School gardens common among secondary
schools
- Appear to be associated with better nutrition
indicators, particularly for young people living with poverty
- Implementation of school gardens and
integration within community largely unknown
