There is limited information concerning the dietary intake of toddlers in Australia. Consequently, there is a need for studies investigating toddler intake that use dietary assessment measures that are valid and place a low participant burden on caregivers. The aim of this study was to determine the relative validity of a single 24-h dietary recall (24HR) in measuring the intake of five nutrients in a cohort of Australian toddlers compared to a combined 24HR and 2-day estimated food record (2DFR). A single 24HR and a 2DFR were collected from a cohort of Australian toddlers ( = 699) at approximately 12 months of age as part of the Study of Mothers' and Infants' Life Events affecting oral health (SMILE) project. Relative validity of one day of dietary data (24HR) in assessing intake of energy, protein, calcium, iron, and added sugars was tested against three days of dietary data (24HR + 2DFR) using paired -tests, Bland-Altman analysis, cross-classification, and weighted Kappa statistic. Classification analysis found good agreement between the 24HR and 24HR + 2DFR for all nutrients with the percentage classified in the same tertile at 57.9% and above. The weighted Kappa statistic found acceptable agreement for all nutrients. This study suggests that a 24HR is a valid assessment tool for estimating the relative intake of energy, protein, calcium, iron, and added sugars among Australian toddlers at the individual level.
关于澳大利亚幼儿的饮食摄入量，相关信息有限。因此，需要开展研究调查幼儿的摄入量，使用既有效又能降低照顾者负担的饮食评估方法。本研究旨在比较单次 24 小时膳食回顾（24HR）和 2 天估计食物记录（2DFR）在测量澳大利亚幼儿五种营养素摄入量方面的相对有效性。在 Study of Mothers' and Infants' Life Events affecting oral health (SMILE) 项目中，约在 12 个月大时，从澳大利亚幼儿队列中收集了单次 24HR 和 2DFR。采用配对检验、Bland-Altman 分析、交叉分类和加权 Kappa 统计检验，评估了一天的饮食数据（24HR）在评估能量、蛋白质、钙、铁和添加糖摄入量方面的相对有效性，与三天的饮食数据（24HR + 2DFR）进行了比较。分类分析发现，24HR 和 24HR + 2DFR 对于所有营养素的分类都有很好的一致性，相同三分位的分类百分比在 57.9%及以上。加权 Kappa 统计显示所有营养素的一致性均为可接受。本研究表明，24HR 是一种有效的评估工具，可用于个体水平估计澳大利亚幼儿的能量、蛋白质、钙、铁和添加糖的相对摄入量。
