在线自我管理的数据收集，通过减少后勤负担和成本，可以有利地取代经典的方法，基于营养师的访谈时，评估饮食摄入量的大型流行病学研究。有必要对此类新仪器与传统方法进行比较研究。我们的目的是比较一个NutriNet-Sante基于网络的自我管理的24小时饮食记录与一个24小时的回忆进行的营养师。受试者完成基于网络的记录，第二天通过电话进行营养师指导的24小时回忆（对应于同一天并使用相同的计算机化界面进行数据输入）。受试者为147名48-75岁的志愿者（女性59.2%）。该研究于2009年2月在法国进行。协议进行了评估的组内相关系数（ICC）的食物和能量调整皮尔逊相关的营养素。两种方法之间的一致性很高，尽管可能被高估了，因为两种评估是连续的。仅在消费者中，食品的ICC中位数为男性0.8，女性0.7（范围0.5-0.9）。能量调整的皮尔逊相关系数的中位数为0.8，在两种性别（范围0.6-0.9）。受试者的平均皮尔逊相关性较高，
Online self-administered data collection, by reducing the logistic burden and cost, could advantageously replace classical methods based on dietitian's interviews when assessing dietary intake in large epidemiological studies. Studies comparing such new instruments with traditional methods are necessary. Our objective was to compare one NutriNet-Sante web-based self-administered 24 h dietary record with one 24 h recall carried out by a dietitian. Subjects completed the web-based record, which was followed the next day by a dietitian-conducted 24 h recall by telephone (corresponding to the same day and using the same computerised interface for data entry). The subjects were 147 volunteers aged 48-75 years (women 59.2%). The study was conducted in February 2009 in France. Agreement was assessed by intraclass correlation coefficients (ICC) for foods and energy-adjusted Pearson's correlations for nutrients. Agreement between the two methods was high, although it may have been overestimated because the two assessments were consecutive to one another. Among consumers only, the median of ICC for foods was 0.8 in men and 0.7 in women (range 0.5-0.9). The median of energy-adjusted Pearson's correlations for nutrients was 0.8 in both sexes (range 0.6-0.9). The mean Pearson correlation was higher in subjects
