The study objective was to determine impact of a Farm-to-School intervention on low-income, diverse elementary school students' nutrition-related attitudes, self-efficacy, behaviors, and locally grown vegetable choices.
Six elementary schools within 1 US school district were equally assigned to 1 of 3 conditions: Local Message, Nutrition Message, or Control. Locally grown vegetables (kale, green beans, zucchini, butternut squash, and beets) were served twice during lunch over 16 weeks. "Local" and "Nutrition" groups also received biweekly nutrition education and a messaging campaign in the cafeteria. Knowledge, attitudes, self-efficacy, and related behaviors were assessed using a validated questionnaire. Vegetable selection was assessed using the food service daily production records. General linear model analysis, analysis of covariance, and t tests were performed.
Students in the "Local" group (N = 81) had significantly improved nutrition-related attitudes (p = .0001), preferences (p = .001), and overall vegetable behavior score (p = .002), compared to control (N = 79). There was no difference in overall locally grown vegetable choices, but local beet choices were higher in the "Local" (p = .005) and "Nutrition" (p = .02) groups compared to control.
Messages about local foods in school cafeterias may improve students' attitudes, preferences, and selection of certain locally grown vegetables.
本研究旨在探讨“从农场到学校”干预措施对低收入、多元化小学生营养相关态度、自我效能、行为和当地种植蔬菜选择的影响。
美国一个学区内的 6 所小学被平均分为 3 组：本地信息组、营养信息组和对照组。在 16 周的时间里，午餐中会提供两次当地种植的蔬菜（羽衣甘蓝、青豆、南瓜、胡桃南瓜和甜菜）。“本地”和“营养”组还会接受两周一次的营养教育和在自助餐厅进行宣传活动。使用经过验证的问卷评估知识、态度、自我效能和相关行为。使用餐饮服务每日生产记录评估蔬菜选择。采用一般线性模型分析、协方差分析和 t 检验进行分析。
与对照组（N=79）相比，“本地”组（N=81）的学生营养相关态度（p=0.0001）、偏好（p=0.001）和整体蔬菜行为得分（p=0.002）均显著提高。在整体选择当地种植的蔬菜方面没有差异，但与对照组相比，“本地”（p=0.005）和“营养”（p=0.02）组的本地甜菜选择更高。
学校自助餐厅的本地食品信息可能会改善学生对某些当地种植蔬菜的态度、偏好和选择。
