Abstract
There is an emerging use of brief dietary questionnaires to investigate diet-health relation. We prospectively assess the association between eating attitudes (yes/no) and incident cardiovascular disease (CVD) in 19,138 participants of the Seguimiento Universidad de Navarra (SUN) Cohort. We calculated a baseline healthy-eating attitudes score (in quartiles), positively weighting answers on more fruit, vegetables, fish and fiber and less meat, sweets and pastries, fat, butter, fatty meats and added sugar in drinks. We observed 139 incident cases of CVD. A higher score was associated with a lower risk of CVD [3-5 points Hazard Ratio (HR): 0.38 (95% confidence interval: 0.18-0.81); 6-8 points: 0.57 (0.29-1.12); 9-10 points: 0.31 (0.15-0.67), compared to 0-2 points]. Key contributors were the attitude to increase fruit [HR: 0.59 (0.40-0.87)], vegetables [HR: 0.57 (0.29-1.12)] and fiber intake [HR: 0.69 (0.48-0.98)]. Brief questionnaire on attitudes towards healthy-eating may be a useful tool for the primary prevention of CVD.
