Cardiovascular diseases are strongly related to dietary habits. Diet can be assessed using dedicated questionnaires that can be self-completed by subjects but with the risk of errors.
To compare the completion error rate of two questionnaires designed to assess dietary pattern linked to cardiovascular diseases and to study the correlation between the two questionnaires.
Two questionnaires were used to assess dietary patterns of students: the 14-item Food-Frequency-Questionnaire (FFQ) that was validated against biomarkers, and the Cardiovascular-Dietary-Questionnaire 2 (CDQ2), which is a 19-item-FFQ derived from the previous 14-item FFQ. Both questionnaires assessed the intake of various food groups associated with either favourable or unfavourable effects on cardiovascular risk. A global dietary score was calculated for each questionnaire.
FFQ and CDQ2 were completed by 150 sport degree students. In the case of FFQ, 111 questionnaires out of 150 (74.0%) were incomplete compared to only 1 CDQ2 out of 150 (0.7%) (P<0.001). The correlation coefficient between the overall CDQ2 score and the FFQ dietary score was 0.53 (P<0.01).
The self-completion of CDQ2 compared to FFQ was associated with far less errors. There was a significant correlation between CDQ2 and FFQ. Preference should be given to CDQ2 in clinical practice and in studies where dietary pattern are evaluated without any interviewer.
心血管疾病与饮食习惯密切相关。饮食可通过专门的问卷进行评估，这些问卷可由受试者自行填写，但存在错误风险。
比较两种旨在评估与心血管疾病相关饮食模式的问卷的完成错误率，并研究这两种问卷之间的相关性。
使用两种问卷评估学生的饮食模式：一种是经过生物标志物验证的14项食物频率问卷（FFQ），另一种是心血管饮食问卷2（CDQ2），它是从之前的14项FFQ衍生而来的19项FFQ。两种问卷都评估了与心血管风险有有利或不利影响相关的各种食物组的摄入量。为每份问卷计算了一个总体饮食评分。
150名体育专业学生完成了FFQ和CDQ2。在FFQ方面，150份问卷中有111份（74.0%）不完整，而CDQ2在150份中只有1份（0.7%）不完整（P<0.001）。CDQ2总体评分与FFQ饮食评分之间的相关系数为0.53（P<0.01）。
与FFQ相比，CDQ2的自行填写错误要少得多。CDQ2与FFQ之间存在显著相关性。在临床实践和无需访员的饮食模式评估研究中，应优先选择CDQ2。
