Measuring dietary intake in children and adolescents can be challenging due to misreporting, difficulties in establishing portion size and reliance on recording dietary data via proxy reporters. The aim of this review was to present results from a recent systematic review of reviews reporting and comparing validated dietary assessment tools used in younger populations in the UK. Validation data for dietary assessment tools used in younger populations (≤18 years) were extracted and summarised using results from a systematic review of reviews of validated dietary assessment tools. Mean differences and Bland-Altman limits of agreement (LOA) between the test and reference tool were extracted or calculated and compared for energy, macronutrients and micronutrients. Seventeen studies which reported validation of 14 dietary assessment tools (DATs) were identified with relevant nutrition information. The most commonly validated nutrients were energy, carbohydrate, protein, fat, calcium, iron, folate and vitamin C. There were no validated DATs reporting assessment of zinc, iodine or selenium intake. The most frequently used reference method was the weighed food diary, followed by doubly labelled water and 24 h recall. Summary plots were created to facilitate comparison between tools. On average, the test tools reported higher mean intakes than the reference methods with some studies consistently reporting wide LOA. Out of the 14 DATs, absolute values for LOA and mean difference were obtained for 11 DATs for EI. From the 24 validation results assessing EI, 16 (67%) reported higher mean intakes than the reference. Of the seven (29%) validation studies using doubly labelled water (DLW) as the reference, results for the test DATs were not substantially better or worse than those using other reference measures. Further information on the studies from this review is available on the www.nutritools.org website. Validated dietary assessment tools for use with children and adolescents in the UK have been identified and compared. Whilst tools are generally validated for macronutrient intakes, micronutrients are poorly evaluated. Validation studies that include estimates of zinc, selenium, dietary fibre, sugars and sodium are needed.

测量英国儿童和青少年的能量、宏观和微量营养素摄入量：经过验证的饮食评估工具的比较。

由于误报、难以确定份量以及依赖通过代理报告者记录饮食数据，测量儿童和青少年的膳食摄入量可能具有挑战性。这篇综述的目的是展示最近对英国年轻人群中使用的经过验证的饮食评估工具报告和比较的系统综述的结果。使用对经过验证的饮食评估工具的系统评价的结果提取和总结了在年轻人群（≤18 岁）中使用的饮食评估工具的验证数据。提取或计算测试工具和参考工具之间的平均差异和 Bland-Altman 协议限制 (LOA)，并比较能量、常量营养素和微量营养素。报告了 14 种膳食评估工具 (DAT) 的验证的 17 项研究与相关营养信息一起被确定。最常验证的营养素是能量、碳水化合物、蛋白质、脂肪、钙、铁、叶酸和维生素 C。没有经过验证的 DAT 报告对锌、碘或硒摄入量的评估。最常用的参考方法是称重食物日记，其次是双标水和 24 小时召回。创建摘要图以促进工具之间的比较。平均而言，测试工具报告的平均摄入量高于参考方法，一些研究一致报告了广泛的 LOA。在 14 个 DAT 中，获得了 11 个 EI DAT 的 LOA 绝对值和平均差。在评估 EI 的 24 个验证结果中，16 个（67%）报告的平均摄入量高于参考值。在使用双重标记水 (DLW) 作为参考的七项 (29%) 验证研究中，测试 DAT 的结果并不比使用其他参考测量的结果好或差。有关本次审查研究的更多信息，请访问 www.nutritools.org 网站。已经确定并比较了用于英国儿童和青少年的经过验证的饮食评估工具。虽然工具通常针对大量营养素的摄入进行验证，但对微量营养素的评估却很差。需要包括估计锌、硒、膳食纤维、糖和钠的验证研究。有关本次审查研究的更多信息，请访问 www.nutritools.org 网站。已经确定并比较了用于英国儿童和青少年的经过验证的饮食评估工具。虽然工具通常针对大量营养素的摄入进行验证，但对微量营养素的评估却很差。需要包括估计锌、硒、膳食纤维、糖和钠的验证研究。有关本次审查研究的更多信息，请访问 www.nutritools.org 网站。已经确定并比较了用于英国儿童和青少年的经过验证的饮食评估工具。虽然工具通常针对大量营养素的摄入进行验证，但对微量营养素的评估却很差。需要包括估计锌、硒、膳食纤维、糖和钠的验证研究。
