A Multicomponent, School-Based Intervention, the Shaping Healthy Choices Program, Improves Nutrition-Related Outcomes

Published:February 08, 2017DOI:



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


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


      Schools in northern and central California.


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


      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.


      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.


      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.

          The May 2017 issue of the Journal of Nutrition Education and Behavior carried a Research Article titled “A Multicomponent, School-Based Intervention, the Shaping Healthy Choices Program, Improves Nutrition-Related Outcomes” (JNEB 2017;49:368-379. ). The authors would like to amend some of the statements made in the paper. Additional analyses were conducted to control for clustering and as a result, the authors have clarified that results of the subanalysis of weight-related outcomes were only observed in the district that fully implemented the program.

          We write in response to the article by Scherr et al1 entitled “A multicomponent, school-based intervention, the Shaping Healthy Choices Program, improves nutrition-related outcomes.” We admire Scherr et al for undertaking such a challenging study on so important a topic, and for wisely using a randomized controlled design, the design that allows for the strongest causal inferences.
