PURPOSE
A semi-quantitative food frequency questionnaire (FFQ) was developed for use in the Prospective Epidemiological Research Studies in IrAN (PERSIAN Cohort), investigating non-communicable disease risk factors. This study aimed to assess the validity and reproducibility of this FFQ, through food group intake.
METHODS
Participants, recruited from seven PERSIAN cohort centers, completed the FFQ at the beginning of the study (FFQ1) and at the end (FFQ2), with a 12-month interval in between, during which two 24-h dietary recalls (24 h) were completed each month. Correlation coefficients of the median intake of food groups recorded by the FFQs were compared to those of the 24 h to assess validity, and the two FFQs were compared to assess reproducibility of findings.
RESULTS
Overall, data from 978 participants were included in this validation analysis. Of the 26 food groups assessed, , , , and /, had the strongest correlations (0.6-0.79), while and showed moderate correlations (0.42-0.59). The weakest correlations observed belonged to and (0.23-0.32). Reproducibility was assessed among those who completed both FFQ1 and FFQ2 ( = 848), revealing moderate to strong correlations in all food groups, ranging from 0.42 in to 0.72 in both and
CONCLUSION
The PERSIAN Cohort FFQ is appropriate to rank individuals based on food group intake.
目的
开发了一种半定量食物频率问卷（FFQ），用于伊朗前瞻性流行病学研究（PERSIAN队列），以调查非传染性疾病风险因素。本研究旨在通过食物组摄入量评估该FFQ的有效性和可重复性。
方法
从七个PERSIAN队列中心招募参与者，在研究开始时（FFQ1）和结束时（FFQ2）完成FFQ，中间间隔12个月，在此期间每月完成两次24小时膳食回顾（24h）。将FFQ记录的食物组中位数摄入量的相关系数与24h的相关系数进行比较以评估有效性，并比较两个FFQ以评估结果的可重复性。
结果
总体而言，978名参与者的数据纳入了该验证分析。在评估的26个食物组中，[具体食物组1]、[具体食物组2]、[具体食物组3]和[具体食物组4]具有最强的相关性（0.6 - 0.79），而[具体食物组5]和[具体食物组6]显示出中等相关性（0.42 - 0.59）。观察到的最弱相关性属于[具体食物组7]和[具体食物组8]（0.23 - 0.32）。在完成FFQ1和FFQ2的参与者（n = 848）中评估了可重复性，结果显示所有食物组的相关性从中等到强，范围从[具体食物组9]的0.42到[具体食物组10]和[具体食物组11]的0.72。
结论
PERSIAN队列FFQ适用于根据食物组摄入量对个体进行排名。
