Abstract

OBJECTIVE

To assess the nutritional quality of student canteen purchases at recess and lunch, including: (i) the mean energy (kilojoules), saturated fat (grams), total sugar (grams) and Na (milligrams) and percentage of energy from saturated fat and total sugar; and (ii) the proportion and types of foods purchased that are healthier (green) and less healthy (amber/red) according to a state school canteen policy.

DESIGN

A cross-sectional study of student canteen food and beverage recess and lunch purchases.

SETTING

Twenty-six randomly selected government primary schools that were non-compliant with a state school canteen policy from a region of New South Wales, Australia, were approached to participate.

PARTICIPANTS

Students (aged 5-12 years) of participating schools.

RESULTS

Eighteen schools (69 %) consented to participate. On average students' recess purchases contained 571·2 kJ energy, 1·6 g saturated fat, 11·6 g total sugar and 132·4 mg Na with 10·0 % of energy from saturated fat and 37·8 % of energy from total sugar. Students' lunch purchases contained 685·4 kJ energy, 1·8 g saturated fat, 12·7 g total sugar and 151·4 mg Na with 9·5 % of energy from saturated fat and 31·8 % of energy from total sugar. Less healthy items represented 72 and 76 % of all items purchased at recess and lunch, respectively, with 'savoury snacks' and 'sugar-sweetened ice blocks and slushies' being the most common recess and lunch purchases, respectively.

CONCLUSIONS

There is considerable scope to improve the nutritional quality of student purchases from primary-school canteens, with a high percentage of energy from total sugar. Future research is required to identify effective strategies to enhance compliance with canteen policies and support the purchase of healthier foods from school canteens.

摘要

目的

评估课间和午餐时学生食堂购买食品的营养质量,包括:(i)平均能量(千焦耳)、饱和脂肪(克)、总糖(克)和钠(毫克)以及来自饱和脂肪和总糖的能量百分比;(ii)根据州立学校食堂政策,购买的更健康(绿色)和不太健康(琥珀色/红色)食物的比例和类型。

设计

对学生食堂食品和饮料课间和午餐购买情况进行横断面研究。

地点

澳大利亚新南威尔士州一个地区的 26 所随机选择的不符合州立学校食堂政策的政府小学应邀参与。

参与者

参与学校的学生(年龄 5-12 岁)。

结果

18 所学校(69%)同意参与。平均而言,学生课间购买的食品含有 571.2 千焦耳的能量、1.6 克饱和脂肪、11.6 克总糖和 132.4 毫克钠,其中 10.0%的能量来自饱和脂肪,37.8%的能量来自总糖。学生午餐购买的食品含有 685.4 千焦耳的能量、1.8 克饱和脂肪、12.7 克总糖和 151.4 毫克钠,其中 9.5%的能量来自饱和脂肪,31.8%的能量来自总糖。课间和午餐购买的所有食品中,不太健康的食品分别占 72%和 76%,课间和午餐最常见的购买食品分别是“咸味零食”和“含糖冰棒和冰沙”。

结论

有相当大的空间可以提高小学生食堂购买食品的营养质量,总糖的能量占比很高。未来需要研究确定有效策略,以加强对食堂政策的遵守,支持从学校食堂购买更健康的食品。
