To validate a food frequency questionnaire (FFQ) against multiple 24-hour dietary recalls (DRs) that could be used for Colombian adults.
A convenience sample of 219 individuals participated in the study. The validity of the FFQ was evaluated against multiple DRs. Four dietary recalls were collected during the year, and an FFQ was administered at the end of the study along with the fourth DR.
Deattenuated correlation coefficient for FFQ against mean intake of 4 DRs varied from 0.77 for carbohydrate, 0.55 for energy, and 0.51 for protein. In rural areas, lower correlations were observed. The overall extent of agreement in each quartile of estimated nutrient intake varied from 61% to 83%.
The FFQ provides moderate to high estimates for energy and nutrient intake and can be employed to rank individuals based on their habitual intake.
验证针对可用于哥伦比亚成年人的多次 24 小时膳食回顾（DR）的食物频率问卷（FFQ）的有效性。
本研究采用方便抽样方法，共纳入 219 名参与者。使用多次 DR 来评估 FFQ 的有效性。在一年内收集了 4 次饮食回顾，在研究结束时还进行了 FFQ 调查和第 4 次 DR。
FFQ 与 4 次 DR 平均摄入量的去趋势相关系数从碳水化合物的 0.77 到能量的 0.55 再到蛋白质的 0.51 不等。在农村地区，观察到的相关性较低。在每个估计营养素摄入量四分位数中，总体一致性从 61%到 83%不等。
FFQ 提供了能量和营养素摄入的中等至高估计值，并可用于根据习惯性摄入量对个体进行排名。
