To compare food group intakes and dietary indices estimated from a 14-item food frequency questionnaire (FFQ) with a seven day diet record.
112 Belgian and 114 Italian children (11-12 years) completed the FFQ followed by a seven-day diary (FD) and a retest one week later. Dietary indices were calculated from the FFQ and the FD.
Spearman's correlations between the FFQ items and the diary varied between -0.13 and 0.67. When comparing the FFQ with the FD an overestimation was found for most items. The Excess Index was significantly correlated with energy intake (respectively 0.35 and 0.25 for Belgian and Italian children); the Variety Index with fiber intake (0.26 for both) and Calcium intake (respectively 0.32 and 0.41); the Fiber Index with fiber intake (respectively 0.30 and 0.37) and the Calcium Index with Calcium intake (respectively 0.47 and 0.50).
When the FFQ is used for estimating consumption frequencies, overestimation must be considered. The ability to rank individuals varies considerably between food items. The Calcium index can be useful in situations requiring brief dietary instruments. The value of the other indices is lower although still associations in the expected directions were found.
比较通过14项食物频率问卷（FFQ）估算的食物组摄入量和饮食指数与7天饮食记录的结果。
112名比利时儿童和114名意大利儿童（11 - 12岁）完成了FFQ，随后记录了7天的饮食日记（FD），并在一周后进行了重新测试。从FFQ和FD中计算饮食指数。
FFQ项目与饮食日记之间的斯皮尔曼相关性在 - 0.13至0.67之间。将FFQ与FD进行比较时，大多数项目都存在高估现象。过量指数与能量摄入量显著相关（比利时和意大利儿童分别为0.35和0.25）；品种指数与纤维摄入量（两者均为0.26）和钙摄入量（分别为0.32和0.41）相关；纤维指数与纤维摄入量（分别为0.30和0.37）相关，钙指数与钙摄入量（分别为0.47和0.50）相关。
当使用FFQ估算消费频率时，必须考虑高估的情况。不同食物项目对个体进行排序的能力差异很大。在需要简短饮食工具的情况下，钙指数可能会有用。其他指数的价值较低，尽管仍发现了预期方向上的关联。
