OBJECTIVES/AIMS: We tested the reproducibility and relative validity of a French self-administered food frequency questionnaire (FFQ) against 24-hour dietary records (DRs).
We selected 140 participants from the SU.VI.MAX study. They filled in the FFQ twice at 1-year intervals and completed monthly 24-hour DR during that year. The number of food items in the FFQ was 240.
Reproducibility was high. Medians of Pearson coefficients were 0.70 and 0.65 for nutrients in men and women, respectively. Medians of intraclass correlation coefficients for food were 0.62 in men and 0.65 in women. For nutrients, crude Pearson correlation coefficients for relative validity ranged from 0.28 to 0.67 in men and from 0.25 to 0.55 in women. The Spearman coefficient for alcohol was 0.78 in both genders. For food, the medians of the Spearman coefficient were 0.49 and 0.45 for men and women, respectively. Complete disagreement between the FFQ and 24-hour DRs for ranking subjects according to food consumption was low (about 4%), except for rarely consumed food groups, that is nuts, legumes and offal. Calibration coefficients were estimated by linear regression. All coefficients were lower than one.
Acceptable reproducibility and relative validity were observed in a FFQ designed for French adults.
目的/目标：我们通过与 24 小时饮食记录（DR）相比，测试了法国自行管理的食物频率问卷（FFQ）的可重复性和相对有效性。
我们从 SU.VI.MAX 研究中选择了 140 名参与者。他们在 1 年内填写了两次 FFQ，并在那一年中每月完成 24 小时 DR。FFQ 中的食物项目数量为 240。
可重复性很高。男女营养素的皮尔逊系数中位数分别为 0.70 和 0.65。男性和女性的食物的组内相关系数中位数分别为 0.62 和 0.65。对于营养素，相对有效性的粗皮尔逊相关系数在男性中为 0.28 至 0.67，在女性中为 0.25 至 0.55。男女两性酒精的斯皮尔曼系数均为 0.78。对于食物，男性和女性的斯皮尔曼系数中位数分别为 0.49 和 0.45。根据食物消费对受试者进行排名，FFQ 和 24 小时 DR 之间的完全不一致（约 4%），除了很少食用的食物组，即坚果、豆类和内脏。通过线性回归估计校准系数。所有系数均低于 1。
对于为法国成年人设计的 FFQ，观察到了可接受的可重复性和相对有效性。
