本报告描述了一个基于技术的系统的开发和验证，该系统集成了食物选择，营养和盘子浪费的数据，以生成反馈报告，总结学生在学校用餐时的饮食摄入量。食堂的工作人员使用该系统来记录学校的午餐选择的7年级学生（N=37）在城市特许学校五个月。研究人员使用目视估计方法评估平板废物，该方法针对直接称重的平板废物进行了验证。大多数（97.1%）食物选择通过系统被正确记录。接骨板废弃物的视觉估计值具有极好的评价者间可靠性（r ≥.94），并且与直接测量值一致（rho ≥.75）。每个托盘的平板废物评估需要约10秒。54%的家长持续收到反馈报告。这一基于技术的系统使工作人员能够准确监测学校膳食的饮食摄入量。该系统可能会为午餐菜单的修改提供信息，以减少盘子浪费。
This report describes the development and validation of a technology-based system that integrates data on food choice, nutrition, and plate waste to generate feedback reports summarizing students’ dietary intake at school meals. Cafeteria staff used the system to document the school lunch choices of 7th-graders (N=37) in an urban charter school for five months. Plate waste was assessed by research staff using a visual estimation method that was validated against directly weighed plate waste. Most (97.1%) food choices were correctly recorded through the system. Visual estimates of plate waste had excellent interrater reliability (r’s≥.94) and agreement with direct measurements (rho’s≥.75). Plate waste assessment required approximately 10 seconds per tray. Fifty-four percent of parents received feedback reports consistently. The technology-based system enabled staff to accurately monitor dietary intake at school meals. The system could potentially inform lunch menu modifications aimed at reducing plate waste.
