Abstract

OBJECTIVES

In 2011, the National Afterschool Association adopted the Healthy Eating and Physical Activity (HEPA) standards to address snack quality and physical activity in afterschool programs. Although research has indicated promise in the adoption of these policies by national organizations, less is known about local adoption, implementation, and effectiveness. In this study, we aimed to compare the quality of snacks served at program sites pre- and post-adoption and to determine the quality of non-program snacks compared to program snacks.

METHODS

An interrupted time series design was used to measure snack quality and consumption at 3 policy adopting sites and 2 non-policy adopting sites that served as a comparison control. Trained research staff collected snack type, brand, and amount consumed using a modified quarter-waste method. Analysis on nutrient content of snacks was completed using Nutrition Data System for Research software.

RESULTS

Adoption of the HEPA standards among policy adopting sites did not result in significantly better snack quality. Across all sites, program snacks were healthier than non-program snacks.

CONCLUSION

Pursuing additional components of the HEPA standards related to implementation may be necessary to significantly improve snack quality. Environmental supports such as limiting the amount of non-program snacks available onsite may improve snack quality.

摘要

目的

2011 年,全美课后协会采用健康饮食和体育活动(HEPA)标准来解决课后项目中的零食质量和体育活动问题。尽管有研究表明,这些政策在国家组织中的采用具有一定的前景,但对于地方采用、实施和效果的了解较少。在这项研究中,我们旨在比较采用这些政策前后项目点提供的零食质量,并确定非项目点零食与项目点零食的质量。

方法

采用中断时间序列设计,在 3 个采用政策的点和 2 个作为比较对照组的非采用政策的点测量零食质量和消费情况。经过培训的研究人员使用改良的四分之一丢弃法收集零食类型、品牌和消耗量。使用 Research 软件中的 Nutrition Data System 软件完成对零食营养成分的分析。

结果

在采用政策的点采用 HEPA 标准并没有导致零食质量显著改善。在所有点,项目点的零食比非项目点的零食更健康。

结论

可能需要实施 HEPA 标准的其他相关部分来显著提高零食质量。环境支持,如限制现场提供的非项目点零食的数量,可能会提高零食质量。
