OBJECTIVE
To compare beverages and foods selected by high school students on days when juice was offered (juice days) and not offered (non-juice days) with the reimbursable school meal.
METHODS
Lunch register data from 386 days across 3 low-income Northeast high schools were used to compare juice and non-juice days for average daily selections of meal components and à la carte water and 100% juice sales.
RESULTS
On juice days, 9.9% fewer milks (P < .01) and 7.4% fewer fruits (P < .01) were selected with lunches. In addition, on juice days, 8.2% fewer bottles of water and 24.4% fewer bottles of 100% juice were sold à la carte (P < .05).
CONCLUSIONS AND IMPLICATIONS
Reducing juice availability in the reimbursable school lunch may increase selection of milk and fruit. Future research is warranted to assess how juice availability influences selection of milk, fruit, and water across a range of student populations.
目的
比较高中生在提供果汁的日子（果汁日）和不提供果汁的日子（无果汁日）所选择的饮料和食物与可报销的学校午餐情况。
方法
利用东北部3所低收入高中386天的午餐登记数据，比较果汁日和无果汁日午餐各组成部分的日均选择情况以及单点水和100%果汁的销售情况。
结果
在果汁日，午餐时选择的牛奶减少了9.9%（P < .01），水果减少了7.4%（P < .01）。此外，在果汁日，单点的瓶装水销量减少了8.2%，100%果汁的瓶装销量减少了24.4%（P < .05）。
结论与启示
在可报销的学校午餐中减少果汁供应可能会增加牛奶和水果的选择。有必要开展进一步研究，以评估果汁供应如何影响不同学生群体对牛奶、水果和水的选择。
