An accurate assessment of food intake is necessary to monitor nutritional status. However, differences in cultures and dietary habits between communities make it necessary to create culturally specific tools to evaluate food intake. This study aimed to develop and validate a short food frequency questionnaire (SH-FFQ) in Iranian adults.
This perspective longitudinal study was conducted during four months. A total of 135 healthy adults over 18 years (both of sex) were included. The 24-hour dietary recalls (24-HDRs) (three times per month: A total of 12 numbers) were collected as reference for validation of SH-FFQ. Participants completed two SH-FFQ, once at the end of the fourth month for validity, and the second one week after the first administration for reliability assessing.
Reliability analysis showed that the mean difference between the two SH-FFQs was not statistically significant ( > 0.05). None of the correlation coefficients (r) were less than 0.4. There was a substantial or perfect correlation (r > 0.6) in 85.1% and a moderate correlation (r = 0.4-0.6) in 14.9% of food items. For validity assessment, the average values of two SH-FFQ1 and SH-FFQ2 (SH-FFQ) were compared with the average values of 24-HDRs. All of the intraclass correlation coefficients (ICCs) of between SH-FFQ and 24-HDRs were equal to or greater than 0.4 (except one item). Moderate correlation (ICC = 0.4-0.6) and substantial or perfect correlation (ICC > 0.6) were observed in 38.3% and 59.6% of food items, respectively.
The current study showed that the developed SH-FFQ is reliable and valid in Iranian adults. This developed SH-FFQ can be used in nutritional assessments.
准确评估食物摄入量对于监测营养状况至关重要。然而，不同社区之间的文化和饮食习惯差异使得有必要创建针对特定文化的工具来评估食物摄入量。本研究旨在开发并验证一种适用于伊朗成年人的简短食物频率问卷（SH-FFQ）。
本前瞻性纵向研究历时四个月。共纳入135名18岁以上的健康成年人（男女均有）。收集24小时膳食回顾（24-HDRs）（每月三次，共12次）作为验证SH-FFQ的参考。参与者完成两份SH-FFQ，一份在第四个月末用于效度验证，另一份在首次填写一周后用于信度评估。
信度分析表明，两份SH-FFQ之间的平均差异无统计学意义（>0.05）。所有相关系数（r）均不小于0.4。85.1%的食物项目具有高度或完美相关性（r>0.6），14.9%的食物项目具有中度相关性（r=0.4-0.6）。为进行效度评估，将两份SH-FFQ1和SH-FFQ2（SH-FFQ）的平均值与24-HDRs的平均值进行比较。SH-FFQ与24-HDRs之间的所有组内相关系数（ICC）均等于或大于0.4（一项除外）。分别在38.3%和59.6%的食物项目中观察到中度相关性（ICC=0.4-0.6）和高度或完美相关性（ICC>0.6）。
当前研究表明，所开发的SH-FFQ在伊朗成年人中具有可靠性和有效性。这种开发的SH-FFQ可用于营养评估。
