Bonne reproductibilité dans une population étudiante d’un court questionnaire (14-item Food Frequency Questionnaire) évaluant l’alimentation à risque vasculaire
Abstract
Unlabelled - Diet is a modifiable risk factor of atherosclerosis. A 14-item food frequency questionnaire (FFQ) has been developed. The reproducibility of this FFQ is unknown in a student population whereas its use could be of interest. Methods - This FFQ allows calculating different scores for different food groups involved in cardiovascular disease. The vascular dietary score (VDS) can be calculated. The VSD ranges from -17 to +19. The higher the VSD, the better diet. Reproducibility was assessed in sports faculty students using mean tests comparing measurement 1 and 2 (minimum time interval ≥ 7 days) and intra-class correlation (ICC) tests. Results - Thirty students (50% men) were included in a French Sports Faculty. Time between two FFQ assessments was 19 ± 9 days. Mean VSD was 0.50 ± 3.70 for the first assessment and 0.30 ± 3.14 for the second one (non significant). Any score for each food group was statistically significant between the first and the second measurement. ICC of VSD was 0.68 [95% confidence interval: 0.43-0.83]. Conclusion - This FFQ that assesses a risky vascular diet has good reproducibility. This tool could be useful for large studies involving students.
