BUDS（通过每日校餐平衡营养）计划改善了小学生的校餐摄入量，促进了他们的健康成长和饮食行为

摘要(中文译文)

学校供餐在儿童日常营养和终身饮食习惯的形成中起着关键作用。本研究旨在评估BUDS（通过每日学校供餐实现均衡营养）项目对大韩民国小学生学校供餐摄入量、饮食行为及体重相关结局的影响。我们假设参与BUDS项目会增加学校供餐摄入量，并改善体重状况和饮食行为。共有478名二、三年级学生参与了为期6个月的BUDS项目，该项目包括每月一次的营养教育和促进学校供餐摄入的策略。研究采用基于人工智能的食物扫描仪客观监测每日学校供餐摄入量。在项目前后评估了人体测量指标、饮食行为（采用儿童营养商数NQ-C测量）、零食偏好和膳食摄入量。共有450名学生完成了该项目，平均年龄为8.0 ± 0.7岁。学校供餐摄入量从69.1%增加至77.0%（p < .001）。体重不足组和正常体重组的BMI z评分呈上升趋势，而所有组的体脂百分比和去脂体重均有所增加。学校供餐摄入量改善越大，达到或维持正常体重的几率越高（OR = 2.68，95% CI = 1.27-5.65）。供餐摄入量与NQ-C总分之间呈正相关（r = 0.216，p < .001）。该相关性也特定于食用多样化配菜和减少屏幕时间等行为。基于学校的BUDS项目在增加学校供餐摄入量、促进更健康的饮食行为和支持健康体重结局方面显示出成效，尤其是在体重不足的儿童中。

Abstract

School meals play a critical role in the daily nutrition of children and the development of lifelong eating habits. The objective of this study was to assess the impact of the BUDS (Balanced nutrition through daily school meals) program on school meal intake, eating behaviors, and weight-related outcomes among elementary school students in the Republic of Korea. We hypothesized that participation in the BUDS program would increase school meal intake and lead to improvements in weight status and eating behaviors. A total of 478 second- and third-grade students participated in the 6-month BUDS program, which included monthly nutrition education and strategies to promote school meal consumption. An artificial intelligence-based food scanner was utilized to objectively monitor daily school meal intake. Anthropometric measurements, eating behaviors (as measured by the Nutrition Quotient for Children, NQ-C), snack preferences, and dietary intake were assessed before and after the program. A total of 450 students completed the program, with a mean age of 8.0 ± 0.7 years. School meal intake increased from 69.1% to 77.0% (p < .001). The BMI z-scores of the underweight and normal weight groups demonstrated an upward trend, while the body fat percentage and fat-free mass of all groups exhibited an increase. Greater improvement in school meal intake was associated with higher odds of achieving or maintaining a normal weight (OR = 2.68, 95% CI = 1.27-5.65). A positive correlation was identified between meal intake and total NQ-C score (r = 0.216, p < .001). This correlation was also found to be specific to behaviors such as consuming diverse side dishes and reducing screen time. The school-based BUDS program demonstrated efficacy in increasing school meal intake, promoting healthier eating behaviors, and supporting healthy weight outcomes, particularly among underweight children.
