The aim of this study was to validate the EPIC food frequency questionnaire in Lebanon. The validation was done by comparing data collected from the EPIC FFQ with that collected from three 24-hour recalls. Unadjusted and energy adjusted correlations, Bland Altman plots, and weighed kappa statistics were used to assess the agreement between the two methods. Unadjusted and energy-adjusted correlation coefficients ranged from -0.002 (vitamin A) to 0.337 (carbohydrates) and were all statistically significant except for vitamin D, vitamin E, vitamin A, selenium, and niacin. The weighed kappa estimates for unadjusted data ranged from -0.05 (vitamin C) to 0.248 (magnesium). Weighed kappa for energy-adjusted data ranged from -0.034 (vitamin A) to 0.203 (phosphorus). The visual inspection of the Bland-Altman plots revealed over-estimation of energy, carbohydrates, protein, and fat intakes by the FFQ method. This validation study demonstrated an overall acceptable agreement compared to the 24-h recall method.
