目的:在这个混合方法案例研究中,我们探讨了影响在娱乐设施中采用和实施《艾伯塔省儿童和青少年营养指南》的因素,并评估其实施对食物环境的影响。
方法:定性数据是通过访谈生成的,观察,和文件审查。使用经过验证和新开发的食品环境评估工具评估了食品环境的质量。
结果:尽管在采用指南方面存在的障碍很少,事实证明,实施它们更具挑战性。对健康项目缺乏盈利能力的担忧阻碍了实施,时间,和资源约束。不限制不健康选择的准则被利益相关者更好地接受。准则的实施支持创造健康的食物环境,但在特许权(16%)和自动售货机(20%)内,健康物品的供应仍然非常有限,儿童继续主要购买不健康的物品。
结论:研究结果表明,当存在不健康的物品时,儿童选择健康的选择是不充分的。因此,尽管以非限制性形式引入营养指南在某些方面可能是有利的,随着时间的推移,他们应该得到加强,以便他们建议接近或完全消除不健康的选择。
OBJECTIVE: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.
