Dietary assessment method developed in Department of Social and Preventive Epidemiology at the University of Tokyo and mainly used for research
*Self-administered diet history questionnaire (DHQ)
To target for Japanese population living in Japan and to quantitatively
assess dietary habits (nutrient intake and food intake) during the preceding
month, Sasaki et al has developed a self-administered diet history questionnaire
(DHQ). DHQ is a so-called questionnaire of diet record method which includes
mainly a food frequency questionnaire and questions for dietary behaviors.
DHQ is a 16-page structured questionnaire (the latest version is a 22 pages)
consisting of more than 400 questions, and dietary intake derived from
149 foods and over 30 nutrients is calculated. Estimates of dietary intake
are calculated using an ad hoc computer algorithm for the DHQ.
A result of the DHQ obtained from an individual can be printed out and used for explanation or/and for dietary counseling. In addition, in case of a large population (many people), database for the population comprised of individual data is produced and can be used for studies of various purposes and statistical analyses.
DHQ has been tested for validation by several methods, and its validation is almost equal or a little higher in comparison to similar dietary questionnaires developed in Japan or in other countries (1-7). DHQ is one of the scarce methods for dietary assessment whose reliability (strength and limitation) has been evidenced, and DHQ is used in several studies conducted in Japan.
*Examples of the DHQ (in Japanese)
1. First page of the questionnaire
2. Individual feedback (a part of basic results for healthy person)
3. Individual feedback (a part of hypercholesterolaemic person)
*Brief-type self-administered diet history questionnaire (BDHQ)
BDHQ has been developed as a simple version of DHQ, targeted
for Japanese adults. BDHQ assesses amount of nutrients habitually consumed
from foods usually eaten (exclude intake from dietary supplements) as a
unit of individual, in relatively easy way. BDHQ is designed to obtain
each individual’s information of nutrient intake, food intake, as well
as information of few markers of dietary behaviors. BDHQ is a 2-pages (A3
size) or 4-pages (A4 size), consisting of 102 questions. While having characteristics
of DHQ, the structure of BDHQ as well as response style to each question
and data process have been made simpler than DHQ. BDHQ has been developed
to aim for uses in large-scale epidemiologic research, research with topics
other than nutrition, and relatively easy-leveled nutrition education and
dietary counseling targeted for a large number of people.
In similar to DHQ, a result of the DHQ obtained from an individual can be printed out and used for explanation or/and for dietary counseling. In addition, in case of a large population (many people), database for the population comprised of individual data is produced and can be used for studies of various purposes and statistical analyses.
Original papers about validation of BDHQ have yet existed, and its validation has reported only through research report so far (8). In addition, BDHQ was used in a study (9), and the structure of the BDHQ and its validation was written in a published paper.
Moreover, BDHQ for 3-year olds, elementary school upper-graders, adolescents (students in middle schools and high schools), and elderly has been in development.
*Examples of the BDHQ (in Japanese)
1. First and second page of the questionnaire
2. Individual feedback (a part of basic results for healthy person)
3. Individual feedback (a part of Food Balance Guide)
4. Individual feedback (a part of hypercholesterolaemic person)
5. Individual feedback (a part of table for individual data)
6. Data file of calculated nutrient intakes
*The validity of DHQ and BDHQ
The validity of DHQ and BDHQ was examined as follows;
Food intake→Public Health Nutr. 2011 14:1200-11. (in Japanese)
Nutrient intake→J Epidemiol. 2012 22:151-9. (in Japanese)
