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.
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.
Public elementary schools in California.
An evaluation sample (938 students and nineteen teachers) and a dissemination sample (195 245 students and 7359 teachers).
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).
The SMC programme demonstrates the potential for moderate to high public health impact.
本研究使用RE-AIM（覆盖、效果、采用、实施、维持）框架，评估了“塑造我的选择”（SMC）项目对公众健康的总体影响。该项目是为三年级学生开发的一项为期10周的校内营养教育课程。
采用随机对照试验评估该项目，并对存档数据进行二次分析以描述其传播情况。数据收集自项目记录、教师调查问卷以及学生的课前、课后和3个月随访调查问卷。
加利福尼亚州的公立小学。
一个评估样本（938名学生和19名教师）和一个传播样本（195245名学生和7359名教师）。
在评估样本中，从课前到课后，对照组和干预组在营养知识、自我效能感、结果期望以及蔬菜、水果（仅女生）、苏打水和低营养高能量食物的摄入量方面存在差异。在3个月的随访期间（效果），知识、结果期望和蔬菜摄入量变化的组间差异持续存在。评估样本中100%的干预教师实施了所有课程（实施）。传播样本代表了2010 - 2011年加利福尼亚州公立小学三年级学生的42%（覆盖）和三年级教室的39%（采用）。在随后的学年（2011 - 2012年；维持），传播样本中37%的三年级教师重新订购了SMC材料。
SMC项目显示出对公众健康产生中度至高度影响的潜力。
