The energy and nutrient intakes estimated by the food frequency questionnaire (FFQg) method based on food groups were compared with the results from the weighed dietary record method. The correlation coefficients between the two methods for energy, fat, protein, carbohydrate, calcium, iron and dietary fiber intakes were higher than 0.4 and the intakes of those nutrients were not significantly different between the two methods according to paired t-test (p>0.05). The ratio of the value obtained by the FFQg method to that obtained by the record method ranged from 74% (dietary fiber) to 110% (salt). The correlation coefficients for food intakes estimated by the two methods were as follows : 0.44 for cereals, 0.83 for pulses, 0.44 for fruits, 0.53 for green-yellow vegetables, 0.63 for other vegetables and mushrooms, 0.43 for fishes, 0.47 for eggs, and 0.78 for milks. The correlation of 10 of 16 food groups was significant at a p<0.05 level. These results showed that the FFQg is a useful method for estimating energy and nutrient intakes. However, the FFQg method tested on 122 students who were beginners of dietary questionnaires suggested that the probability of errors in their answers is comparatively high.
