目的：测量在美国农业部（USDA）在洛杉矶联合学区（LAUSD）的可报销午餐计划中引入沙拉吧计划作为午餐菜单选项后，小学生水果和蔬菜（F&V）消费的变化。设计：采用24小时食品召回问卷，在沙拉吧干预前后（分别为1998年和2000年）对儿童进行横断面抽样调查。计算了F&V消耗频率。环境：评价是在参加沙拉吧方案和美国农业部可报销午餐方案的三所拉丁美洲州小学进行的。研究对象：337名2 -5年级（7-11岁）儿童。结果：引入沙拉吧后，研究儿童的F&V消费频率显著增加（2.97至4.09，P< 0.001）。食品和饮料消费频率的增加几乎都是由于午餐时间的增加（84%）。在学校引入沙拉吧后，儿童的平均能量、胆固醇、饱和脂肪和总脂肪摄入量明显低于引入沙拉吧前的儿童摄入量。结论：在美国农业部可报销午餐计划中，将沙拉吧作为午餐菜单选项可以显著增加低收入家庭小学生的餐饮消费频率。
Objective: To measure change in fruit and vegetable (F&V) consumption among elementary-school children after the introduction of a salad bar programme as a lunch menu option in the US Department of Agriculture's (USDA) reimbursable lunch programme in Los Angeles Unified School District (LAUSD).Design: A cross-sectional sample of children was interviewed before and after a salad bar intervention (1998 and 2000, respectively) utilising a 24-hour food recall questionnaire. Frequencies of F&V consumption were calculated.Setting: The evaluation took place in three LAUSD elementary schools participating in the salad bar programme and the USDA reimbursable lunch programme.Subjects, Three hundred and thirty-seven children in 2nd-5th grade (7-11 years old).Results: After the salad bar was introduced, there was a significant increase in frequency (2.97 to 4.09, P< 0.001) of F&V consumed among the children studied. The increase in frequency of F&V consumed was almost all due to an increase during lunch (84%). Mean energy, cholesterol, saturated fat and total fat intakes were significantly lower in the children after the salad bar was introduced in the schools compared with the intakes in the children before the salad bar was introduced.Conclusion: A salad bar as a lunch menu option in the USDA reimbursable lunch programme can significantly increase the frequency of F&V consumption by elementary-school children living in low-income households.
