The study objective was to determine the relative validity and reproducibility of a modified FFQ for ranking the nutrient intakes of New Zealand toddlers aged 12-24 months.
Cross-sectional study.
Dunedin, New Zealand.
One hundred and fifty-two participants completed a ninety-five-item FFQ twice, and five days of weighed diet recording (WDR), over one month. Validity and reproducibility were assessed for crude data and for data that were weighted for total fruit and vegetable intake (FV-adjusted).
De-attenuated correlations between FV-adjusted FFQ data and WDR data ranged from 0.45 (Zn) to 0.77 (Ca). The percentage classified to the correct WDR quartile by the FV-adjusted FFQ data ranged from 34.6% (total fat, Zn) to 50.3% (Fe). Average gross misclassification was 3%. Bland-Altman statistics showed crude data had a range of 128-178% agreement with the WDR and mean FV-adjusted intakes had 112-160% agreement. FV-adjusted intra-class correlations, assessing reproducibility, ranged from 0.65 (vitamin C) to 0.75 (Ca).
The Eating Assessment in Toddlers (EAT) FFQ showed acceptable to good relative validity, and good reproducibility, for ranking participants' nutrient intake and is able to identify toddlers at extremes of the nutrient intake distribution. It will be a useful tool for investigating toddlers' nutrient intakes in studies that require a method of dietary assessment with low respondent burden.
本研究的目的是确定一种改良的食物频率问卷（FFQ）用于对12至24个月大的新西兰幼儿营养摄入量进行排名的相对有效性和可重复性。
横断面研究。
新西兰达尼丁。
152名参与者在一个月内完成了一份95项的FFQ两次，以及连续五天的称重饮食记录（WDR）。对原始数据以及针对总水果和蔬菜摄入量进行加权的数据（FV调整后的数据）评估有效性和可重复性。
FV调整后的FFQ数据与WDR数据之间去衰减后的相关性范围为0.45（锌）至0.77（钙）。FV调整后的FFQ数据将参与者正确分类到WDR四分位数的百分比范围为34.6%（总脂肪、锌）至50.3%（铁）。平均总体错误分类率为3%。Bland-Altman统计显示原始数据与WDR的一致性范围为128 - 178%，平均FV调整后的摄入量一致性为112 - 160%。评估可重复性的FV调整后的组内相关性范围为0.65（维生素C）至0.75（钙）。
幼儿饮食评估（EAT）FFQ在对参与者营养摄入量进行排名方面显示出可接受至良好的相对有效性和良好的可重复性，并且能够识别营养摄入量分布极端的幼儿。在需要一种应答者负担低的饮食评估方法的研究中，它将是调查幼儿营养摄入量的有用工具。
