In this mixed-methods case study, we explored factors influencing the adoption and implementation of the Alberta Nutrition Guidelines for Children and Youth within recreational facilities, and assessed the impact of their implementation on the food environment.
Qualitative data were generated via interviews, observations, and document reviews. The quality of the food environment was assessed using validated and newly developed food environment assessment tools.
Whereas few barriers existed in terms of adopting the guidelines, implementing them proved much more challenging. Implementation was impeded by concerns about the lack of profitability of healthy items, time, and resource constraints. Guidelines that do not restrict the availability of unhealthy options are better accepted by stakeholders. Implementation of the guidelines supported creation of a healthy food environment, but the availability of healthy items remained very limited within the concession (16%) and vending machines (20%), and children continued to purchase primarily unhealthy items.
Findings suggest that children choose healthy options insufficiently when unhealthy items are present. Thus, although introducing the nutrition guidelines in a nonrestrictive format may have been advantageous in some ways, they should be strengthened over time so that they recommend near or total elimination of unhealthy options.
在这项混合方法的案例研究中,我们探讨了影响艾伯塔省儿童和青少年营养指南在娱乐设施中采用和实施的因素,并评估了其实施对食品环境的影响。
通过访谈、观察和文件审查收集定性数据。使用经过验证的和新开发的食品环境评估工具对食品环境质量进行评估。
虽然在采用指南方面几乎没有障碍,但实施起来却困难得多。对健康食品缺乏盈利能力的担忧、时间和资源限制阻碍了实施。不限制不健康食品供应的指南更容易被利益相关者接受。指南的实施有助于营造健康的食品环境,但在小卖部(16%)和自动售货机(20%)中,健康食品的供应仍然非常有限,儿童仍然主要购买不健康食品。
研究结果表明,当有不健康食品时,儿童选择健康食品的情况不足。因此,尽管以非限制性的形式引入营养指南在某些方面可能是有利的,但随着时间的推移,这些指南应该得到加强,以便建议几乎完全或完全消除不健康食品。
