This study aimed at developing a valid culture-sensitive quantitative food frequency questionnaire (FFQ) for Qatari adults. A convenient sample of healthy Qataris ( = 107) were recruited from family members of Qatar University students. The Diet History Questionnaire II of the US National Cancer Institute was translated to Arabic language, back-translated to English, pilot tested, and then modified accordingly to be used in Qatari setting. Participants were asked to complete the translated version of the FFQ. This FFQ was then validated against three 24 h diet recall (24 hDR) including a weekend day. Participants were asked to complete the FFQ again after one-month period to measure its repeatability. Dietary data were analyzed using the dietary analysis software ESHA. The validity and reliability of FFQ were assessed by comparing the median intake of nutrients and foods and by calculating the Pearson correlation coefficients. The median nutrient intakes assessed by the second FFQ were higher than that reported in the baseline FFQ1 except for fat. The percentage of increase varies between 1.5% and 96%. Results of the second FFQ indicated an overestimation of intake for most nutrients (macro and micro). Macronutrient intakes assessed by the two FFQ and 24 hDR were strongly correlated. The correlation coefficients for micronutrient intakes between FFQ2 and 24hDR were lower than that of the two FFQs except for calcium (r = 0.55) and sodium (r = 0.643). They ranged from (-0.17) for fluorine to (0.643) for sodium. The agreement rates for classifying macronutrient intakes into same or adjacent quartile were between 79.4% and 100% for the two FFQs and between 71% and 100% for the second FFQ and 24hDR. The reported consumption of food groups estimated by FFQ2 was significantly higher than that reported by FFQ1. In conclusion, the developed FFQ was sufficiently valid to assess energy and macronutrients but not micronutrients. The reliability was adequate for most nutrients.
本研究旨在为卡塔尔成年人开发一种有效的文化敏感型定量食物频率问卷（FFQ）。从卡塔尔大学学生的家庭成员中方便地招募了 107 名健康的卡塔尔人作为研究对象。美国国家癌症研究所的饮食历史问卷 II 被翻译成阿拉伯语，再翻译成英语，进行预试验，然后根据卡塔尔的情况进行相应修改，用于研究对象。参与者被要求完成翻译版的 FFQ。然后，将该 FFQ 与 3 次 24 小时饮食回忆（24 hDR）进行验证，包括一个周末。一个月后，参与者被要求再次完成 FFQ，以测量其可重复性。使用饮食分析软件 ESHA 分析饮食数据。通过比较营养素和食物的中位数摄入量，并计算 Pearson 相关系数，评估 FFQ 的有效性和可靠性。第二次 FFQ 评估的中位数营养素摄入量高于基线 FFQ1 报告的中位数，除了脂肪。增加的百分比在 1.5%到 96%之间变化。第二次 FFQ 的结果表明，大多数营养素（宏量和微量）的摄入量都被高估了。两次 FFQ 和 24 hDR 评估的宏量营养素摄入量高度相关。FFQ2 和 24 hDR 之间的微量营养素摄入量的相关系数低于两个 FFQ，除了钙（r = 0.55）和钠（r = 0.643）。它们的范围从氟（-0.17）到钠（0.643）。将两种 FFQ 的宏量营养素摄入量分类为相同或相邻四分位数的一致率在 79.4%到 100%之间，而第二次 FFQ 和 24 hDR 的一致率在 71%到 100%之间。FFQ2 估计的食物组的报告摄入量明显高于 FFQ1。总之，开发的 FFQ 足以评估能量和宏量营养素，但不能评估微量营养素。大多数营养素的可靠性都足够高。
