Abstract

OBJECTIVE

The primary objective of this study was to examine the validity and reliability of a semi-quantitative food frequency questionnaire (FFQ) among Chinese children aged 12-17 years.

METHODS

A semi-quantitative 72-food item FFQ was developed for children aged 12-17 years. The reliability and validity of this FFQ were evaluated against 24-h dietary recalls (24 h DRs) to measure the consumption of foods and nutrients. We administered two FFQs and three DRs to children (N = 160) over a period of 1 month to evaluate the reliability and validity. Reliability was examined by quartile agreement and intraclass correlation coefficients (ICCs), and validity was examined by quartile agreement, Bland-Altman plots and correlation with DRs.

RESULTS

For reliability, the ICCs between the two FFQs ranged from 0.21 to 0.76 for foods and nutrients, and the quartile agreement ranged from 70.0% to 95.0% in the same or adjacent quartiles. Spearman's correlation coefficients of foods and nutrients between the second FFQ and the 24 h DRs ranged from -0.04 to 0.59. The Bland-Altman plots demonstrated good agreement across the range of intakes among nutrients. The quartile agreement ranged from 50.0% to 100.0%, with infrequent misclassification.

CONCLUSION

The FFQ assessment of dietary intakes demonstrated acceptable relative validity and high reproducibility for Chinese children aged 12-17 years.

摘要

目的

本研究的主要目的是检验适用于 12-17 岁中国儿童的半定量食物频率问卷（FFQ）的有效性和可靠性。

方法

为 12-17 岁儿童制定了半定量 72 种食物项目的 FFQ。通过与 24 小时膳食回顾（24 h DR）相比较，评估该 FFQ 对食物和营养素摄入的可靠性和有效性。我们在 1 个月的时间内对 160 名儿童进行了两次 FFQ 和三次 24 h DR 的调查，以评估可靠性和有效性。通过四分位一致性和组内相关系数（ICC）评估可靠性，通过四分位一致性、Bland-Altman 图和与 24 h DR 的相关性评估有效性。

结果

在可靠性方面，两次 FFQ 之间的 ICC 值范围为 0.21-0.76，用于食物和营养素，同一或相邻四分位区间的四分位一致性范围为 70.0%-95.0%。第二次 FFQ 与 24 h DR 之间食物和营养素的 Spearman 相关系数范围为-0.04-0.59。Bland-Altman 图显示，在摄入量范围内，营养物质之间存在良好的一致性。四分位一致性范围为 50.0%-100.0%，且分类错误的频率较低。
