The European study MetaCardis aims to investigate the role of the gut microbiota in health and cardiometabolic diseases in France, Germany, and Denmark. To evaluate long-term diet-disease relationships, a food frequency questionnaire (FFQ) was found to be the most relevant dietary assessment method for the MetaCardis study.
The objectives of this study were to describe the development of three semiquantitative online FFQs used in the MetaCardis study-one FFQ per country-and to assess the relative validity of the French MetaCardis FFQ.
The layout and format of the MetaCardis FFQ was based on the European Prospective Investigation of Cancer (EPIC)-Norfolk FFQ and the content was based on relevant European FFQs. Portion size and nutrient composition were derived from national food consumption surveys and food composition databases. To assess the validity of the French MetaCardis FFQ, a cross-sectional study design was utilized.
PARTICIPANTS/SETTING: The validation study included 324 adults recruited between September 2013 and June 2015 from different hospitals in Paris, France.
Food intakes were measured with both the French MetaCardis FFQ and 3 consecutive self-administered web-based 24-hour dietary recalls (DRs).
Several measures of validity of the French MetaCardis FFQ were evaluated: estimations of food groups, energy, and nutrient intakes from the DRs and the FFQ, Spearman and Pearson correlations, cross-classification, and Bland-Altman analyses.
The French MetaCardis FFQ tended to report higher food, energy, and nutrient intakes compared with the DRs. Mean correlation coefficient was 0.429 for food, 0.460 for energy, 0.544 for macronutrients, 0.640 for alcohol, and 0.503 for micronutrient intakes. Almost half of participants (44.4%) were correctly classified within tertiles of consumption, whereas 12.9% were misclassified in the opposite tertile. Performance of the FFQ was relatively similar after stratification by sex.
The French MetaCardis FFQ was found to have an acceptable level of validity and may be a useful instrument to rank individuals based on their food and nutrient intakes.
欧洲的MetaCardis研究旨在调查法国、德国和丹麦肠道微生物群在健康和心血管代谢疾病中的作用。为了评估长期饮食与疾病的关系，食物频率问卷（FFQ）被认为是MetaCardis研究中最相关的饮食评估方法。
本研究的目的是描述MetaCardis研究中使用的三种半定量在线FFQ（每个国家一种FFQ）的开发过程，并评估法国MetaCardis FFQ的相对效度。
MetaCardis FFQ的布局和格式基于欧洲癌症前瞻性调查（EPIC）-诺福克FFQ，内容基于相关的欧洲FFQ。食物分量和营养成分来自国家食物消费调查和食物成分数据库。为了评估法国MetaCardis FFQ的效度，采用了横断面研究设计。
参与者/地点：验证研究纳入了2013年9月至2015年6月期间从法国巴黎不同医院招募的324名成年人。
分别用法国MetaCardis FFQ和连续3次基于网络的24小时饮食回顾（DR）测量食物摄入量。
评估了法国MetaCardis FFQ的几种效度指标：从DR和FFQ中估计食物组、能量和营养素摄入量，Spearman和Pearson相关性分析、交叉分类分析以及Bland-Altman分析。
与DR相比，法国MetaCardis FFQ倾向于报告更高的食物、能量和营养素摄入量。食物摄入量的平均相关系数为0.429，能量为0.460，宏量营养素为0.544，酒精为0.640，微量营养素为0.503。几乎一半的参与者（44.4%）在消费三分位数内被正确分类，而12.9%被错误分类到相反的三分位数。按性别分层后，FFQ的表现相对相似。
发现法国MetaCardis FFQ具有可接受的效度水平，可能是一种根据个体食物和营养素摄入量进行排名的有用工具。
