Hennepin County partnered with schools to implement lunchroom strategies to encourage fruit and vegetable consumption. An in-depth evaluation measured changes in consumption following implementation of encouragement strategies including slicing apples and attractive labels.
A pre-post prospective evaluation measured changes in average fruit and vegetable consumption at 2 elementary schools. The plate waste method was used to weigh individual waste. To measure consumption, 373 students were matched pre/post. Additional measures included change in fruit and vegetable selection, change in whole servings consumed and apple consumption.
Average fruit consumption increased by 3.0 g (p = .09), average vegetable consumption increased by 1.1 g (p = .27), neither significantly. The number of students selecting fruit significantly increased (p = .02), while the number taking vegetables increased, but not significantly (p = .28). The number of students consuming an entire serving of fruit (p = .15) or vegetables (p = .45) both increased but not significantly. Apple consumption more than doubled at one school.
Implementing lunchroom changes can increase the number of students selecting fruit, and changes including slicing can increase consumption of apples. Additional strategies are needed to increase vegetable selection and fruit and vegetable consumption.
亨内平县与学校合作实施食堂策略，以鼓励食用水果和蔬菜。一项深入评估测量了实施包括切苹果和使用吸引人的标签在内的鼓励策略后食用量的变化。
一项前后对比的前瞻性评估测量了两所小学平均水果和蔬菜食用量的变化。采用餐盘浪费法对个人浪费量进行称重。为测量食用量，对373名学生进行了前后匹配。其他测量指标包括水果和蔬菜选择的变化、整份食用量的变化以及苹果食用量。
平均水果食用量增加了3.0克（p = 0.09），平均蔬菜食用量增加了1.1克（p = 0.27），均无显著差异。选择水果的学生人数显著增加（p = 0.02），而选择蔬菜的学生人数增加，但不显著（p = 0.28）。食用一整份水果（p = 0.15）或蔬菜（p = 0.45）的学生人数均增加，但不显著。在一所学校，苹果食用量增加了一倍多。
在食堂实施改变可以增加选择水果的学生人数，包括切片在内的改变可以增加苹果的食用量。需要采取更多策略来增加蔬菜的选择以及水果和蔬菜的食用量。
