BACKGROUND/OBJECTIVES: The purpose of this study was to evaluate the feasibility of application of the draft nutritional standards for school lunches in the Republic of Korea (South Korea) from the supplier perspective.
SUBJECTS/METHODS: In November 2018, a pilot operation was conducted at 104 participating schools for 2 weeks each by applying the draft standards A and B. To evaluate the ease and appropriateness of application of the standards, we analyzed the nutritional values and food cost of the school lunches for 2 weeks before and for 4 weeks under the pilot operation. We conducted an online survey of school dietitians or nutrition teachers of the participating schools to evaluate the feasibility of application of the standards in school lunch sites.
The proportions of schools of which lunches met the reference values of the school's own nutritional standards were 19.2% for the standards A and 21.2% for the standards B. The food cost of school lunches applying the standards A (KRW 2,880) was significantly lower than that of school lunches applying the standards B (KRW 3,030) or the existing standards (KRW 2,980). As a result of the survey, the mean score for the ease of application was significantly higher for the standards B (2.75) than for the standards A (2.24). The proportions of school dietitians or nutrition teachers reporting no problem in meeting an existing food cost standard were 72.5% for the standards A and 61.8% for the standards B, respectively. The overall appropriateness of application was higher for the standards B, because almost two-thirds (58.8%) of the respondents answered that the standards B were more appropriate than the standards A.
The standards B were more feasible to apply as nutritional standards for school lunches than the standards A from the supplier perspective.
背景/目的：本研究旨在从供应商角度评估韩国学校午餐营养标准草案的应用可行性。
对象/方法：2018年11月，通过应用标准A和标准B，在104所参与学校进行了为期2周的试点运营。为评估标准应用的难易程度和适宜性，我们分析了试点运营前2周和运营期间4周学校午餐的营养价值和食品成本。我们对参与学校的学校营养师或营养教师进行了在线调查，以评估该标准在学校午餐场所应用的可行性。
午餐符合学校自身营养标准参考值的学校比例，标准A为19.2%，标准B为21.2%。应用标准A的学校午餐食品成本（2880韩元）显著低于应用标准B的学校午餐（3030韩元）或现行标准（2980韩元）。调查结果显示，标准B在应用难易程度上的平均得分（2.75）显著高于标准A（2.24）。报告在满足现有食品成本标准方面没有问题的学校营养师或营养教师比例，标准A为72.5%，标准B为61.8%。标准B在应用的总体适宜性上更高，因为近三分之二（58.8%）的受访者回答标准B比标准A更合适。
从供应商角度来看，作为学校午餐营养标准，标准B比标准A更具应用可行性。
