As part of an evaluation of Ontario's School Food and Beverage Policy (P/PM 150) in a populous Ontario region, this research aimed to: 1) identify, describe and categorize beverages and snacks available for purchase in secondary school vending machines according to P/PM 150 standards; and 2) compare the number and percentage of beverages and snacks within P/PM 150 categories (Sell Most, Sell Less, Not Permitted) from Time I (2012/2013) to Time II (2014).
Representatives from consenting secondary schools assisted researchers in completing a Food Environmental Scan checklist in Times I and II. Sourced nutritional content information (calories, fats, sodium, sugars, ingredients and % daily values) was used to categorize products. The number and percentage of products in P/PM 150 categories were compared between Times by paired t-tests.
Of 26 secondary schools participating in total, 19 participated in both Time periods and were included in the study. There were 75 beverages identified (59 Time I, 45 Time II), mostly water, juices and milk-based beverages; and 132 types of snacks (87 Time I, 103 Time II), mostly grain-based snacks, vegetable/fruit chips, and baked goods. A majority of schools offered one or more Not Permitted beverages (47% Time I, 58% Time II) or snacks (74% Time I, 53% Time II). Significantly more schools met P/PM 150 standards for snacks (p = 0.02) but not beverages in Time II.
Full P/PM 150 compliance was achieved by few schools, indicating that schools, school boards, public health, and food services need to continue to collaborate to ensure nutrient-poor products are not sold to students in school settings.
作为对安大略省一个人口众多地区的学校食品和饮料政策(P/PM 150)进行评估的一部分,本研究旨在:1)根据P/PM 150标准,识别、描述和分类中学自动售货机中可供购买的饮料和零食;2)比较从第一阶段(2012/2013年)到第二阶段(2014年)P/PM 150类别(最常销售、较少销售、禁止销售)中的饮料和零食的数量及百分比。
来自同意参与的中学的代表协助研究人员在第一阶段和第二阶段完成食品环境扫描清单。利用获取的营养成分信息(卡路里、脂肪、钠、糖、成分及每日摄入量百分比)对产品进行分类。通过配对t检验比较不同阶段P/PM 150类别中产品的数量及百分比。
在总共参与的26所中学中,19所学校在两个阶段都参与了研究并被纳入本研究。共识别出75种饮料(第一阶段59种,第二阶段45种),主要是水、果汁和乳基饮料;以及132种零食(第一阶段87种,第二阶段103种),主要是谷物类零食、蔬菜/水果片和烘焙食品。大多数学校提供了一种或多种禁止销售的饮料(第一阶段47%,第二阶段58%)或零食(第一阶段74%,第二阶段53%)。在第二阶段,达到P/PM 150零食标准的学校显著增多(p = 0.02),但饮料方面未达标。
很少有学校完全符合P/PM 150标准,这表明学校、学校董事会、公共卫生部门和食品服务机构需要继续合作,以确保在学校环境中不向学生出售营养欠佳的产品。
