背景/目的：儿童和饮食评估工具（CADET）是一个24小时的食物日记，测量3-7岁儿童的营养摄入量，重点是水果和蔬菜的消费。到目前为止，CADET还没有被用于测量8-11岁儿童的营养摄入量。为了确保新分配的部分大小为这个年龄较大的组是有效的，参与者被要求完成CADET日记（学校和家庭的食物日记），同时1天称重记录。+/- 1.4，51%女孩）参加了研究。提取水果和蔬菜的总摄入量（以克为单位）和其他营养素，使用t检验和Pearson r相关性比较CADET日记和称重记录的平均摄入量。Bland-Altman分析也进行了评估，以评估这两种方法之间的协议。结果：相关性比较CADET日记称重记录高水果，蔬菜和水果和蔬菜相结合（r = 0.7）。Bland-Altman图的结果显示，水果和蔬菜摄入量的平均差异为54 g（95%置信区间：-88，152）。CADET是唯一的工具，已在英国人口验证，并提供营养水平的数据，儿童的diets.CONCLUSIONS：从这项研究的结果得出结论，CADET可以提供高质量的营养数据，适合评估干预研究，现在为3-11岁的儿童，重点是水果和蔬菜的摄入量。
BACKGROUND/OBJECTIVES: The Child And Diet Evaluation Tool (CADET) is a 24-h food diary that measures the nutrition intake of children aged 3-7 years, with a focus on fruit and vegetable consumption. Until now CADET has not been used to measure nutrient intake of children aged 8-11 years. To ensure that newly assigned portion sizes for this older age group were valid, participants were asked to complete the CADET diary (the school and home food diary) concurrently with a 1-day weighed record.SUBJECTS/METHODS: A total of 67 children with a mean age of 9.3 years (s.d.: +/- 1.4, 51% girls) participated in the study. Total fruit and vegetable intake in grams and other nutrients were extracted to compare the mean intakes from the CADET diary and Weighed record using t-tests and Pearson's r correlations. Bland-Altman analysis was also conducted to assess the agreement between the two methods.RESULTS: Correlations comparing the CADET diary to the weighed record were high for fruit, vegetables and combined fruit and vegetables (r = 0.7). The results from the Bland-Altman plots revealed a mean difference of 54 g (95% confidence interval: -88, 152) for combined fruit and vegetables intake. CADET is the only tool recommended by the National Obesity Observatory that has been validated in a UK population and provides nutrient level data on children's diets.CONCLUSIONS: The results from this study conclude that CADET can provide high-quality nutrient data suitable for evaluating intervention studies now for children aged 3-11 years with a focus on fruit and vegetable intake.
