尽管国家学校午餐计划 (NSLP) 中广泛支持将沙拉吧作为增加水果和蔬菜 (F&V) 摄入量的一种手段，但对其使用的实证支持有限。这项横断面研究调查了弗吉尼亚州提供全民免费餐食的 Title I 小学的沙拉吧使用情况与食品和饮料选择和消费之间的关系。随机选择三对匹配的学校（三对有沙拉吧；三对没有[对照]）。数字图像印版浪费方法评估了 F&V 选择、浪费和消耗。对来自一年级至五年级学生的 N = 1559 个托盘（N = 760 个沙拉吧；N = 799 个对照）进行了分析（92.5% 参与 NSLP；98.6% 属于少数族裔）。沙拉吧的使用率差异很大（8.2%-63.8%）。在配对中观察到不同的 F&V 选择和消费模式。与匹配对照相比，一所沙拉吧学校的蔬菜选择较高（+43.6g；q < .001），两所沙拉吧学校的蔬菜消费较高（+15.3g [q = .005]；+8.3g [q = .022]）。 2 所沙拉吧学校的学生比对照组选择了更多的水果（+30.2 克和+18 克；qs < .001），但所有 3 对学生的水果消耗量有所不同。沙拉吧可能会促进儿童的蔬菜摄入量。各校间的结果不一致表明，除了沙拉吧的使用之外，学校食品环境因素也影响了食品和饮料的消费。
Despite widespread support for salad bars as a means to increase fruit and vegetable (F&V) intake within the National School Lunch Program (NSLP), empirical support for their use is limited. This cross-sectional study examined associations between salad bar access and F&V selection and consumption in Title I elementary schools in Virginia serving universal free meals. Three matched pairs of schools (3 with salad bars; 3 without [control]) were randomly selected. Digital imagery plate waste methods assessed F&V selection, waste, and consumption. N = 1559 trays (N = 760 salad bar; N = 799 control) from 1st-5th grade students were analyzed (92.5% NSLP participation; 98.6% racial/ethnic minority). Salad bar usage varied widely (8.2%-63.8%). Different patterns of F&V selection and consumption were observed across pairs. Vegetable selection was higher in one salad bar school (+43.6g; q < .001) and vegetable consumption higher in 2 salad bar schools (+15.3g [q = .005]; +8.3g [q = .022]), compared with matched controls. Students in 2 salad bar schools selected more fruit than controls (+30.2g and +18g; qs < .001), yet fruit consumption differed across all 3 pairs. Salad bar access might facilitate children’s vegetable intake. Inconsistent results across school pairs suggest that school food environment factors other than salad bar access influenced F&V consumption.
