Abstract

Background: With the growing accessibility of the internet, dietary assessment tools, including food frequency questionnaires (FFQs), are increasingly being adapted for web platforms. A web-based FFQ was developed as a dietary assessment tool for healthy adults in Iran.

Objective: This study aimed to develop an online FFQ for dietary data collection among Iranian adults and to compare its performance with the validated Iranian printed FFQ.

Methods: Eligible participants were randomly assigned to complete both the printed and web-based FFQs. The type of FFQ alternated for each participant after 10 days. The agreement between the two FFQs was assessed using the Bland-Altman method and correlation analysis.

Results: Of the 190 participants, final analyses were conducted on 141 individuals, including 70 females (49.6%) and 71 males (50.4%) who completed both FFQs. Agreement was high for all nutrient intakes (r > .8). Among food groups, "Whole grains" showed the highest correlation (r = .84), while "Potato" had the lowest (r = .25). There were no significant differences in the time taken to complete the questionnaires.

Conclusion: The web-based FFQ demonstrated strong agreement with the validated printed FFQ, accurately reflecting nutrient and food group intakes in Iranian adults.

伊朗成年人食物频率自填问卷在线版。

背景：随着互联网的日益普及，饮食评估工具，包括食物频率问卷（FFQs），越来越多地被用于网络平台。开发了一个基于网络的FFQ，作为伊朗健康成年人的饮食评估工具。目的：本研究旨在开发用于伊朗成年人饮食数据收集的在线FFQ，并将其性能与经过验证的伊朗印刷FFQ进行比较。方法：符合条件的参与者被随机分配完成印刷和基于网络的ffq。10天后，每个参与者的FFQ类型交替进行。采用Bland-Altman方法和相关分析评估两个FFQs之间的一致性。结果：在190名参与者中，对141名个体进行了最终分析，其中70名女性（49.6%）和71名男性（50.4%）完成了两个ffq。所有营养素摄入量的一致性都很高（rbb0.8）。在食物组中，“全谷物”的相关性最高（r = 0.84），而“土豆”的相关性最低（r = 0.25）。在完成问卷的时间上没有显著差异。结论：基于网络的FFQ与经过验证的印刷FFQ表现出强烈的一致性，准确地反映了伊朗成年人的营养和食物组摄入量。
