OBJECTIVE
To evaluate the effectiveness of the Shaping Healthy Choices Program (SHCP).

DESIGN
A clustered, randomized, controlled intervention lasting 1 school year.

SETTING
Schools in northern and central California.

PARTICIPANTS
Fourth-graders (aged 9-10 years) at 2 control schools (n = 179) and 2 intervention schools (n = 230).

INTERVENTION
Garden-enhanced education, family, and community partnerships; increased regionally procured produce in the lunchroom; and school-site wellness committees.

MAIN OUTCOME MEASURES
Changes in body mass index (BMI) percentiles/Z-scores; nutrition knowledge, science process skills, and vegetable identification and preferences; and reported fruit and vegetable intake.

ANALYSIS
Student t test, chi-square, ANOVA of change, and multilevel regression mixed model to evaluate change in outcomes with school as a random effect to account for cluster design effects. Statistical significance was set at P < .05.

RESULTS
There was a greater improvement in BMI percentile (-6.08; P < 0.01), BMI Z-score (-0.28; P < .001), and waist-to-height ratio (-0.02; P < .001) in the intervention compared with the control schools.

CONCLUSIONS AND IMPLICATIONS
The SHCP resulted in improvements in nutrition knowledge, vegetable identification, and a significant decrease in BMI percentiles. This supports the concept that the SHCP can be used to improve the health of upper elementary school students.
