Abstract
OBJECTIVES
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.
AIM
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.
MATERIALS AND METHODS
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.
RESULTS
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).
CONCLUSION
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.
