Technology-based dietary assessment has promising benefits on improving accuracy and reducing cost of dietary data collection. The validity of technology-based tools in children/adolescents was examined. A systematic literature search was performed to identify studies published till September 2019. In total, 26 studies with 29 validation-related estimations were selected; 13 web-based 24-hdietary recalls (image assisted; = 12, drop-down food list; = 13), 4 mobile applications and 3 web-based dietary records (image based; = 2 and image assisted; = 1, drop-down food list; = 3) and 6 web-based food frequency questionnaires (FFQs) (image assisted; = 3). Fourteen studies were addressed to adolescents, ten studies to children (principally 9-11 years old) and two studies to mixed study samples. Validation was mostly performed through 24-h dietary recalls and dietary records while in some cases objective methods were used. Image-assisted 24-h dietary recalls presented good level of agreement with paper-based methods, yet principally in adolescents. Mobile-application dietary records with image-based facilities and drop-down food lists were found to accurately record dietary intake even when compared with objective methods. FFQs, mainly examined in adolescents, had good level of agreement with the "gold standard" dietary records method. The validity of technology-based methods could be supported yet various technical/methodological issues need better clarification.
基于技术的饮食评估在提高饮食数据收集的准确性和降低成本方面具有广阔的前景。本研究旨在评估基于技术的工具在儿童和青少年中的有效性。系统检索了截至 2019 年 9 月发表的研究。共纳入 26 项研究，涉及 29 项验证相关的评估；13 项基于网络的 24 小时膳食回顾（图像辅助； = 12，下拉式食物列表； = 13），4 项移动应用程序和 3 项基于网络的饮食记录（图像基础； = 2 和图像辅助； = 1，下拉式食物列表； = 3）和 6 项基于网络的食物频率问卷（FFQ）（图像辅助； = 3）。14 项研究针对青少年，10 项研究针对儿童（主要是 9-11 岁），2 项研究针对混合研究样本。验证主要通过 24 小时膳食回顾和饮食记录进行，在某些情况下还使用了客观方法。图像辅助的 24 小时膳食回顾与基于纸张的方法具有较好的一致性，但主要在青少年中。具有基于图像的设施和下拉式食物列表的移动应用程序饮食记录可以准确记录饮食摄入，甚至与客观方法相比也是如此。FFQ 主要在青少年中进行了评估，与“金标准”饮食记录方法具有较好的一致性。然而，需要更好地阐明各种技术/方法问题，以支持基于技术的方法的有效性。
