Objective:
The current study evaluated the overall public health impact of the 'Shaping Up My Choices' (SMC) programme, a 10-week school-based nutrition education curriculum developed for third-grade students, using the RE-AIM (Reach, Efficacy, Adoption, Implementation, Maintenance) framework.
Design:
Randomized controlled trial to evaluate the programme and secondary analysis of archival data to describe dissemination. Data were collected from programme records, teacher surveys and student pre-, post- and 3-month follow-up surveys.
Setting:
Public elementary schools in California.
Subjects:
An evaluation sample (938 students and nineteen teachers) and a dissemination sample (195 245 students and 7359 teachers).
Results:
In the evaluation sample, differences between the control and intervention groups were observed for nutrition knowledge, self-efficacy, outcome expectancies, and intakes of vegetables, fruit (girls only), soda, and low-nutrient high-energy foods from pre- to post-survey. Group differences in change in knowledge, outcome expectancies and vegetable intake were sustained through the 3-month follow-up (efficacy). One hundred per cent of intervention teachers in the evaluation sample implemented all of the lessons (implementation). The dissemination sample represented 42% of third-grade students (reach) and 39% of third-grade classrooms in public elementary schools in California during 2010-2011 (adoption). Thirty-seven per cent of third-grade teachers in the dissemination sample reordered SMC materials during the subsequent school year (2011-2012; maintenance).
Conclusions:
The SMC programme demonstrates the potential for moderate to high public health impact.
