School-based interventions hold promise for child obesity prevention. Implemented as a part of the Winning With Wellness obesity prevention project, the "Go Slow Whoa" meal pattern (GSW) was designed to promote healthier foods in school cafeterias. This investigation determined perceived program effectiveness and impact on student's food purchases.
A mixed method design was used, including focus groups with cafeteria staff (CS), quantitative analysis of CS and teacher surveys, and pre-post analysis of cafeteria sales. A total of 37 CS and 131 teachers from 7 schools in northeast Tennessee participated.
CS recognized the important role of school nutrition services in influencing student choices, yet perceived lack of administrative support for cafeteria-based interventions and minimal interaction with teachers were barriers. CS also believed that students choose less nutritious options due to family influence. Cafeteria sales indicated that changes were made in menu planning and production, yet students' choices improved minimally. Teachers expressed moderate levels of confidence in GSW as influential in children's dietary habits.
Successful implementation of school-based nutrition programs requires supportive policies, administrators, and teachers. CS should be included in program implementation efforts and the role of school nutrition services should be maximized.
基于学校的干预措施有望预防儿童肥胖。作为“健康赢未来”肥胖预防项目的一部分，“慢下来”膳食模式（GSW）旨在促进学校自助餐厅提供更健康的食物。本研究旨在确定该项目的感知效果及其对学生食物购买的影响。
采用混合方法设计，包括与自助餐厅工作人员（CS）进行焦点小组讨论、对 CS 和教师进行定量分析以及对自助餐厅销售情况进行前后分析。田纳西州东北部的 7 所学校共有 37 名 CS 和 131 名教师参与了研究。
CS 认识到学校营养服务在影响学生选择方面的重要作用，但他们认为缺乏行政支持、与教师的互动有限是障碍。CS 还认为，由于家庭的影响，学生选择了营养成分较低的食物。自助餐厅销售数据表明，菜单规划和生产方面发生了变化，但学生的选择变化不大。教师对 GSW 作为影响儿童饮食习惯的因素表示出中等程度的信心。
成功实施基于学校的营养计划需要得到支持性政策、管理人员和教师的支持。应让 CS 参与到项目实施工作中，并最大限度地发挥学校营养服务的作用。
