背景:政策,系统,和环境(PSE)政策,系统,和环境(PSE)旨在支持健康饮食行为的改变策略,通过使健康食品在社区中更容易获得和获取来增强最佳营养。PSE变革策略可以补充和加强知识,技能,以及通过个体水平营养教育获得的行为。
目的:本范围审查旨在(1)确定现有的评估儿童早期的文献(即,5岁以下儿童)支持健康饮食行为的PSE变更策略,以及(2)描述用于评估已确定PSE变更策略的评估工具。
方法:三个数据库(PubMed、CINAHL,和WebofScience)用于系统地搜索2013年至2023年之间以英语撰写并在美国(US)进行的文章,这些文章评估了支持幼儿健康饮食行为的PSE改变策略(即,5岁以下儿童)。两名研究成员进行了审查,讨论和调和差异,直到就观察者之间的可靠性达成共识。
结果:本综述的结果确定了48项研究,这些研究评估了支持健康饮食行为的儿童早期PSE改变策略,36项研究使用以PSE为中心的评估工具(n=25)来评估这些策略。大多数工具(80%)评估了PSE变更策略,以支持在幼儿教育环境中获取和提供健康的食品和饮料选择。研究没有评估儿童水平的结果(即,态度,preferences,和行为),以展示儿童早期营养的改善。只有60%的工具报告了有效性或可靠性的证据。
结论:本范围综述中确定的大多数研究旨在评估健康饮食PSE改变策略,重点是改善儿童早期教育环境中健康食品和饮料的获取和供应。需要未来的研究来开发和验证以PSE为重点的评估工具,以评估儿童水平的健康饮食习惯和行为。
BACKGROUND: Policy, Systems, and Environmental (PSE) Policy, Systems, and Environmental (PSE) change strategies aimed at supporting healthy eating behaviors work to enhance optimal nutrition by making healthy foods more available and accessible in the community. PSE change strategies can complement and strengthen knowledge, skills, and behaviors obtained through individual-level nutrition education.
OBJECTIVE: This scoping review aimed to (1) identify existing literature evaluating early childhood (i.e., children under five years) PSE change strategies supporting healthy eating behaviors and (2) describe the evaluation tools used to assess the identified PSE change strategies.
METHODS: Three databases (PubMed, CINAHL, and Web of Science) were used to systematically search for articles published between 2013 and 2023 written in English and conducted in the United States (US) that evaluated PSE change strategies supporting healthy eating behaviors in young children (i.e., children under the age of five years). Two study members conducted the review, discussing and reconciling discrepancies until a consensus was reached for inter-observer reliability.
RESULTS: Findings from this review identified 48 studies evaluating early childhood PSE change strategies supporting healthy eating behaviors, with 36 studies using PSE-focused evaluation tools (n=25) to evaluate these strategies. Most tools (80%) assessed PSE change strategies supporting access and availability of healthy food and beverage options in early childhood education settings. Studies did not evaluate child-level outcomes (i.e., attitudes, preferences, and behaviors) to showcase improvement of early childhood nutrition. Only 60% of the tools reported evidence of validity or reliability.
CONCLUSIONS: Most of the studies identified in this scoping review were aimed to evaluate healthy eating PSE change strategies focused on improving access to and availability of healthy foods and beverages in early childhood education settings. Future research is needed to develop and validate PSE-focused evaluation tools assessing child-level healthy eating practices and behaviors.
