在线膳食评估工具可以降低管理成本，并促进大规模研究随访期间的重复膳食评估。然而，由于这些工具的测量误差，关于偏差的信息是有限的。我们开发了一种在线24小时回忆（myfood 24），并将其性能与传统的面试官管理的多遍24小时回忆进行了比较，并根据生物标志物对两者进行了评估。代谢稳定的成年人被招募并完成了新的在线饮食回忆，基于访谈的多遍回忆和一套参考措施。根据间隔2周的3 × 24小时回忆来估计长期饮食摄入量。将蛋白质、钾和钠的估计摄入量与尿生物标志物浓度进行比较。将估计的总糖摄入量与预测性生物标志物进行比较，并将估计的能量摄入量与通过加速度计和热量计测量的能量消耗进行比较。营养素摄入量也进行了比较，从采访者管理的多通24小时回忆。至少有一次从212名参与者那里收到了生物标志物样本。与生物标志物相比，两种自我报告的饮食评估工具都导致了衰减。在线工具的衰减系数约为0.2-0.3，反映排名摄入量的偏相关系数约为0.3-0.4。这大致类似于行政上更为繁琐的基于访谈的工具。来自myfood 24的其他营养素估计值比基于访谈的工具低约10-20%，一致性范围很广。组内相关系数约为0.4-0.5，表明一致性中等。我们的研究结果表明，虽然与生物标志物测量相比，两种自我报告饮食测量的结果都有所减弱，但在一系列测量中，myfood 24在线24小时回忆与更耗时且成本更高的基于访谈者的24小时回忆相当。本文的在线版本（10.1186/s12916-018-1113-8）包含补充材料，可供授权用户使用。
Online dietary assessment tools can reduce administrative costs and facilitate repeated dietary assessment during follow-up in large-scale studies. However, information on bias due to measurement error of such tools is limited. We developed an online 24-h recall (myfood24) and compared its performance with a traditional interviewer-administered multiple-pass 24-h recall, assessing both against biomarkers. Metabolically stable adults were recruited and completed the new online dietary recall, an interviewer-based multiple pass recall and a suite of reference measures. Longer-term dietary intake was estimated from up to 3 × 24-h recalls taken 2 weeks apart. Estimated intakes of protein, potassium and sodium were compared with urinary biomarker concentrations. Estimated total sugar intake was compared with a predictive biomarker and estimated energy intake compared with energy expenditure measured by accelerometry and calorimetry. Nutrient intakes were also compared to those derived from an interviewer-administered multiple-pass 24-h recall. Biomarker samples were received from 212 participants on at least one occasion. Both self-reported dietary assessment tools led to attenuation compared to biomarkers. The online tools resulted in attenuation factors of around 0.2–0.3 and partial correlation coefficients, reflecting ranking intakes, of approximately 0.3–0.4. This was broadly similar to the more administratively burdensome interviewer-based tool. Other nutrient estimates derived from myfood24 were around 10–20% lower than those from the interviewer-based tool, with wide limits of agreement. Intraclass correlation coefficients were approximately 0.4–0.5, indicating consistent moderate agreement. Our findings show that, whilst results from both measures of self-reported diet are attenuated compared to biomarker measures, the myfood24 online 24-h recall is comparable to the more time-consuming and costly interviewer-based 24-h recall across a range of measures.
