BACKGROUND & AIMS: Little is known about the validity of repeated 24-h dietary recalls (24-HDR) as a measure of total energy intake (EI) in young children. This study aimed to evaluate the validity of proxy-reported EI by comparison with total energy expenditure (TEE) measured by the doubly labeled water (DLW) technique.
The agreement between EI and TEE was investigated in 36 (47.2% boys) children aged 4-10 years from Belgium and Spain using subgroup analyses and Bland-Altman plots. Low-energy-reporters (LER), adequate-energy-reporters (AER) and high-energy-reporters (HER) were defined from the ratio of EI over TEE by application of age- and sex-specific cut-off values.
There was good agreement between means of EI (1500 kcal/day) and TEE (1523 kcal/day) at group level though in single children, i.e. at the individual level, large differences were observed. Almost perfect agreement between EI and TEE was observed in thin/normal weight children (EI: 1511 kcal/day; TEE: 1513 kcal/day). Even in overweight/obese children the mean difference between EI and TEE was only -86 kcal/day. Among the participants, 28 (78%) were classified as AER, five (14%) as HER and three (8%) as LER.
Two proxy-reported 24-HDRs were found to be a valid instrument to assess EI on group level but not on the individual level.
关于重复24小时膳食回顾法（24-HDR）作为幼儿总能量摄入（EI）测量方法的有效性，人们了解甚少。本研究旨在通过与双标记水（DLW）技术测量的总能量消耗（TEE）进行比较，评估代理报告的EI的有效性。
使用亚组分析和布兰德-奥特曼图，对来自比利时和西班牙的36名4至10岁儿童（47.2%为男孩）的EI和TEE之间的一致性进行了研究。通过应用年龄和性别特异性临界值，根据EI与TEE的比值定义了低能量报告者（LER）、适当能量报告者（AER）和高能量报告者（HER）。
在组水平上，EI（1500千卡/天）和TEE（1523千卡/天）的均值之间具有良好的一致性，尽管在单个儿童中，即在个体水平上，观察到了较大差异。在体重偏瘦/正常的儿童中，EI和TEE之间观察到几乎完美的一致性（EI：1511千卡/天；TEE：1513千卡/天）。即使在超重/肥胖儿童中，EI和TEE之间的平均差异也仅为-86千卡/天。在参与者中，28名（78%）被归类为AER，5名（14%）为HER，3名（8%）为LER。
发现两次代理报告的24-HDR是评估组水平而非个体水平EI的有效工具。
