This study sought to elucidate students' perceptions of school food environments and to assess correlations between perceptions and purchasing and consumption behaviors at school.
Seventh and ninth graders (n = 5365) at 19 schools in multiethnic, low-income California communities participating in the Healthy Eating Active Communities program completed questionnaires assessing their attitudes and behaviors regarding school food environments during spring 2006.
Most students (69%) reported that fresh fruit was important to be able to buy at school; more than chips (21%), candy (28%), or soda (31%). Reported importance of food offerings was correlated with the consumption of those items. Most students did not perceive foods/beverages offered at school to be healthy; fewer than a quarter reported eating fruits or vegetables (FV) at school. Students eating school lunch were more than twice as likely to consume FV, though if they also purchased from competitive venues, their consumption of candy, chips, and soda was similar to their peers who purchased only competitive foods.
Students report healthy foods to be important to be able to buy at school, but do not perceive their school food environment to be healthy and consume more unhealthy foods at school. Students served healthy items via school lunch are more likely to consume them; however, they also purchase and consume unhealthy items if available. Findings suggest that modifying school food environments to facilitate consumption of healthy foods and limit unhealthy foods will better match students' preferences and could lead to improved dietary intake.
本研究旨在阐明学生对学校食物环境的看法，并评估这些看法与在校购买和消费行为之间的相关性。
参与“健康饮食与社区活力”项目的 19 所加利福尼亚多民族低收入社区的 7 年级和 9 年级学生（n=5365）在 2006 年春季完成了问卷，评估他们对学校食物环境的态度和行为。
大多数学生（69%）表示，能够在学校购买新鲜水果很重要；比购买薯片（21%）、糖果（28%）或苏打水（31%）更重要。报告的食物供应重要性与这些项目的消费相关。大多数学生并不认为学校提供的食物/饮料是健康的；不到四分之一的学生报告在学校吃水果或蔬菜。吃学校午餐的学生食用水果和蔬菜的可能性是其两倍多，尽管如果他们也从竞争场所购买，他们食用糖果、薯片和苏打水的量与只购买竞争食品的同龄人相似。
学生报告说，健康食品在学校购买很重要，但他们不认为学校的食物环境是健康的，而且在学校消费更多的不健康食品。通过学校午餐提供健康食品的学生更有可能食用这些食品；然而，如果有这些食品，他们也会购买和食用不健康食品。研究结果表明，改变学校食物环境以促进健康食品的消费和限制不健康食品的消费，将更好地满足学生的偏好，并可能改善饮食摄入。
