We assessed the effect on the food environments of public high schools of Maine's statewide nutrition policy (Chapter 51), which banned "foods of minimal nutritional value" (FMNV) in public high schools that participated in federally funded meal programs. We documented allowable exceptions to the policy and describe the school food environments.
We mailed surveys to 89 high school food-service directors to assess availability pre-Chapter 51 and post-Chapter 51 of soda, other sugar-sweetened beverages, and junk food. Frequency data were tabulated pre-Chapter 51 and post-Chapter 51, and Fisher exact test was used to assess significance in changes. We conducted food and beverage inventories at 11 high schools.
The survey return rate was 61% (N = 54). Availability of soda in student vending significantly decreased pre-Chapter 51 versus post-Chapter 51 (P = .04). No significant changes were found for other sugar-sweetened beverages and junk food. Exceptions to Chapter 51 were permitted to staff (67%), to the public (86%), and in career and technical education programs (31%). Inventories in a subset of schools found no availability of soda for students, whereas other sugar-sweetened beverages and junk food were widely available in à la carte, vending machines, and school stores. Candy, considered a FMNV, was freely available. Soda advertisement on school grounds was common.
Student vending choices improved after the implementation of Chapter 51; however, use of FMNV as the policy standard may be limiting, as availability of other sugar-sweetened beverages and junk food was pervasive. School environments were not necessarily supportive of the policy, as advertisement of soda was common and some FMNV were available. Furthermore, local exceptions to Chapter 51 likely reduced the overall effect of the policy.
我们评估了缅因州全州营养政策(第 51 章)对公立高中食品环境的影响,该政策禁止参与联邦资助膳食计划的公立高中供应“营养价值极低的食品”(FMNV)。我们记录了政策的允许例外情况,并描述了学校的食品环境。
我们向 89 名高中食品服务主任邮寄了调查问卷,以评估在第 51 章之前和之后苏打水、其他含糖饮料和垃圾食品在学校的供应情况。我们在第 51 章之前和之后对数据进行了频数统计,并使用 Fisher 精确检验评估变化的显著性。我们在 11 所高中进行了食品和饮料清查。
调查回复率为 61%(N=54)。学生自动售货机中苏打水的供应在第 51 章之前显著低于之后(P=.04)。其他含糖饮料和垃圾食品没有发现显著变化。第 51 章的例外情况允许提供给员工(67%)、公众(86%)和职业和技术教育计划(31%)。在一组学校的清查中,发现学生无法获得苏打水,而其他含糖饮料和垃圾食品在自助餐厅、自动售货机和学校商店中广泛供应。糖果被认为是 FMNV,可自由获得。学校场地的苏打水广告很常见。
在第 51 章实施后,学生自动售货机的选择有所改善;然而,使用 FMNV 作为政策标准可能是有限的,因为其他含糖饮料和垃圾食品的供应仍然普遍。学校环境不一定支持该政策,因为苏打水的广告很常见,而且一些 FMNV 是可用的。此外,第 51 章的地方例外情况可能会降低该政策的整体效果。
