Estimated Change in Child Fruit & Vegetable Self-efficacy Primary · Beginning to end of school year 2019-20 ( Baseline and ~ 8 months)

Self-efficacy for eating F\&V score is average of responses to five 4-point Likert scale questions. Higher score is higher self-efficacy. Score range is 1 to 4. Change in self-efficacy is based on a model that uses all available data (from baseline and 8-month follow-up). The unit of analysis is participant-timepoint. The analysis accounts for nesting within schools. Using a repeated measures linear mixed model analysis, the results are estimated change in self-efficacy score from baseline to 8-month follow-up, contrasting intervention group to comparison group. From the model, the estimate

Estimated Change in AHEI Healthy Foods Score Primary · Beginning to end of school year 2019-20 ( Baseline and ~ 8 months).

The Healthy Foods Score is a subscale from the modified Alternative Healthy Eating Index (AHEI). Data were derived from a picture sort frequency tool estimating consumption frequencies of ten major food groups of the Navajo diet. Scoring used the published AHEI-2010. The subscale is the sum of scores for fruits (fresh \& dried), vegetables (not salad), whole grains, beans, nuts, only. Values range from 0 to 36. Higher values represent a better outcome. Change in Score is based on a model that uses all available data (from baseline and 8-month follow-up). The model is from a repeated measure

Estimated Ratio of Full Self-efficacy to Grow F&V at School Primary · Beginning to end of school year 2019-20 ( Baseline and ~ 8 months)

Measure derived from Percent of participants at each time point reporting "I know I can". Using generalized mixed models, specifying a binomial distribution, accounting for nesting within schools, the Odds ratio of 8-month follow-up to baseline percent reporting "I know I can" was estimated for both intervention and comparison groups. The overall range in these odds ratios was 0.95 to 3.63 . The contrast of intervention group to comparison group was also an odds ratio.

Group	Value	95% CI
Intervention Group	1.92	1.02 – 3.63
Comparison Group	1.48	0.95 – 2.31

Sponsor's own description

In this study, one year changes in healthy eating and gardening behaviors associated with the intervention were estimated using a group randomized controlled trial design, with the comparison arm receiving a delayed intervention in the following school year.
