We conducted a Brief-type Self-administered Diet History Questionnaire (BDHQ) survey in conjunction with the use of the food-weighing method involving participants of the 2016 Nagasaki Prefecture health and nutrition survey (prefectural survey), in order to compare the obtained data and examine the questionnaire’s usefulness. As the results of a comparison of the two dietary surveys, the difference in the mean values of energy intake was -1.2 to +2.9%, showing the validity of the data. With regard to the level of nutrient intake, the validity was also confirmed, as the difference in values of energy-producing nutrients was less than ±10% for most items. On the other hand, the validity of the data for vitamins was not confirmed, as the difference was more than ±10％ for many items. This variation may be caused by the difference in the time of measurement between the food-weighing method (1 day) and BDHQ (1 month).
