在线饮食评估工具比印刷问卷具有优势，例如自动和直接存储答案的数据，并且有潜力成为有价值的研究方法。我们为 JPHC-NEXT 协议（大规模遗传队列研究的平台）中使用的现有印刷版 FFQ 开发了一个在线调查系统（web-FFQ）。在这里，我们检查了使用此网络 FFQ 根据饮食摄入量对个人进行排名的有效性，以及与印刷问卷 (print-FFQ) 相结合使用的可用性。我们纳入了来自 JPHC-NEXT 协议指定的五个地区的 237 名年龄在 40-74 岁之间的男性和女性。从 2012 年到 2013 年，参与者被要求提供 12 天的称重食物记录 (12d-WFR) 作为参考摄入量，并对印刷版和网络版 FFQ 做出回应。计算了使用 web-FFQ 和 12d-WFR 估计值之间的 Spearman 相关系数 (CC)。将摄入量的交叉分类与使用 print-FFQ 的交叉分类进行了比较。大多数参与者 (83%) 回答说，完成网络 FFQ 与完成印刷调查问卷相当或更容易。男性和女性能量和 53 种营养素的 CC 中值分别为 0.47（范围，0.10-0.86）和 0.46（范围，0.16-0.69）。个体营养素摄入量的 CC 与基于打印 FFQ 的 CC 非常相似，无论响应位置如何。对于许多营养素和食物组来说，基于两个 FFQ 按摄入五分位进行交叉分类是相当准确的。这个在线调查系统是一种相当有效的衡量标准，可以根据多种营养素的摄入量对个人进行排名，就像印刷版的 FFQ 一样。在流行病学研究中混合使用两种 FFQ 进行暴露评估似乎是可以接受的。我们检查了使用网络 FFQ 与打印 FFQ 的摄入量的有效性。基于网络 FFQ 的许多估计显示出中等的有效性。这些 CC（具有 12 天的食物记录）与印刷版 FFQ 的 CC 非常相似。两个 FFQ 的各个排名之间具有良好的一致性。在流行病学研究中混合使用这些 FFQ 进行饮食调查似乎是可以接受的。
Online dietary assessment tools offer advantages over printed questionnaires, such as the automatic and direct data storage of answers, and have the potential to become valuable research methods. We developed an online survey system (web-FFQ) for the existing printed FFQ used in the JPHC-NEXT protocol, the platform of a large-scale genetic cohort study. Here, we examined the validity of ranking individuals according to dietary intake using this web-FFQ and its usability compared with the printed questionnaire (print-FFQ) for combined usage. We included 237 men and women aged 40–74 years from five areas specified in the JPHC-NEXT protocol. From 2012 to 2013, participants were asked to provide 12-day weighed food records (12d-WFR) as the reference intake and to respond to the print- and web-FFQs. Spearman's correlation coefficients (CCs) between estimates using the web-FFQ and 12d-WFR were calculated. Cross-classification of intakes was compared with those using the print-FFQ. Most participants (83%) answered that completing the web-FFQ was comparable to or easier than completing the printed questionnaire. The median value of CCs across energy and 53 nutrients for men and women was 0.47 (range, 0.10–0.86) and 0.46 (range, 0.16–0.69), respectively. CCs for individual nutrient intakes were closely similar to those based on the print-FFQ, irrespective of response location. Cross-classification by quintile of intake based on two FFQs was reasonably accurate for many nutrients and food groups. This online survey system is a reasonably valid measure for ranking individuals by intake for many nutrients, like the printed FFQ. Mixing of two FFQs for exposure assessments in epidemiological studies appears acceptable. We examined validity of intakes using web-FFQ compared with those for the print-FFQ. Moderate validities were shown for many estimates based on the web-FFQ. These CCs (with 12-day food record) were closely similar to those of the print-FFQ. Good concordance between individual rankings were obtained with the two FFQs. Mixing of these FFQs for diet survey in epidemiological studies appears acceptable.
