摘要

目的2011年,国家课后协会采用了健康饮食和体育活动(HEPA)标准,以解决课后项目中的零食质量和体育活动问题。虽然研究表明国家组织有希望采用这些政策,但对地方的采用、实施和有效性知之甚少。在这项研究中,我们的目的是比较项目实施前和实施后的零食质量,并确定非项目零食与项目零食的质量。方法采用中断时间序列设计,对3个政策采用点和2个非政策采用点的零食质量和消费情况进行测量,作为对照。训练有素的研究人员使用改进的四分之一废物法收集零食的类型,品牌和消费量。利用“营养数据研究系统”软件对零食的营养成分进行了分析。结果政策采纳地采用HEPA标准对零食质量没有显著改善作用。在所有网站中,节目零食比非节目零食更健康。结论为显著提高零食质量,有必要制定与实施HEPA标准相关的附加内容。环境方面的支持,如限制现场提供的非节目零食的数量,可能会提高零食的质量。

The Adoption of the Healthy Eating Standards in Local Afterschool Programs Does Not Improve Quality of Snacks.
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.
