Abstract

Background: Health researchers may struggle to choose suitable validated dietary assessment tools (DATs) for their target population. The aim of this review was to identify and collate information on validated UK DATs and validation studies for inclusion on a website to support researchers to choose appropriate DATs.

Design: A systematic review of reviews of DATs was undertaken. DATs validated in UK populations were extracted from the studies identified. A searchable website was designed to display these data. Additionally, mean differences and limits of agreement between test and comparison methods were summarized by a method, weighting by sample size.

Results: Over 900 validation results covering 5 life stages, 18 nutrients, 6 dietary assessment methods, and 9 validation method types were extracted from 63 validated DATs which were identified from 68 reviews. These were incorporated into www.nutritools.org. Limits of agreement were determined for about half of validations. Thirty four DATs were FFQs. Only 17 DATs were validated against biomarkers, and only 19 DATs were validated in infant/children/adolescents.

Conclusions: The interactive www.nutritools.org website holds extensive validation data identified from this review and can be used to guide researchers to critically compare and choose a suitable DAT for their research question, leading to improvement of nutritional epidemiology research.

抽象的

背景：健康研究人员可能难以为他们的目标人群选择合适的经过验证的饮食评估工具（DAT）。这次审查的目的是识别和整理有关经过验证的英国DAT和验证研究的信息，以纳入网站以支持研究人员选择合适的DAT。

设计：对DAT的审查进行了系统的审查。从确定的研究中提取了在英国人群中验证过的DAT。可搜索的网站旨在显示这些数据。此外，还通过一种方法总结了测试方法与比较方法之间的平均差异和一致性极限，并通过样本量进行了加权。

结果：从68个评价中鉴定出的63个经过验证的DAT中，提取了900项验证结果，涵盖5个生命阶段，18种营养素，6种饮食评估方法和9种验证方法类型。这些已合并到www.nutritools.org。确定了约一半验证的协议限制。34个DAT是FFQ。仅针对生物标志物验证了17个DAT，而在婴儿/儿童/青少年中仅验证了19个DAT。

结论：交互式www.nutritools.org网站拥有从此次审查中获得的大量验证数据，可用于指导研究人员针对他们的研究问题进行严格比较和选择合适的DAT，从而改善营养流行病学研究。
