“…In both of the previous reproducibility studies of the old version of the QFFQ, the difference in energy intake between the ®rst and the second QFFQ was 12%. The phenomenon that repeated administration of questionnaires shows lower total intake the second time, was also reported in other studies (Pietinen et al, 1988;Rohan et al, 1987;Fogelholm et al, 1991). Furthermore, it is shown that repeated diet records (Bingham, 1987), recalls (Solvoll et al, 1993) and repeated food frequency questionnaires (Goldbohm et al, 1995) in¯uence the outcome of the study.…”

“…Furthermore, it is shown that repeated diet records (Bingham, 1987), recalls (Solvoll et al, 1993) and repeated food frequency questionnaires (Goldbohm et al, 1995) in¯uence the outcome of the study. One explanation suggested for this kind of difference may be a learning effect (Rohan et al, 1987). Reproducibility studies are often combined with comparisons with other dietary survey methods between the two measurements.…”

Response rates with different distribution methods and reward, and reproducibility of a quantitative food frequency questionnaire

Objectives: To evaluate the use of a self-administered quantitative food frequency questionnaire (QFFQ) in a national dietary survey concerning (a) response rates with different distribution methods and reward; (b) degree of underreporting of energy intake; (c) reproducibility of the QFFQ; and (d) seasonal variation on reported intake. Design and subjects: A pilot study was performed in 1992 to test response rates to the QFFQ with three different distribution methods, with and without reward, in a random sample of 1200 adults aged 16±79 y. In another study, the QFFQ was distributed to a nation-wide, representative random sample of 5008 adults aged 16±79 y during June, September, November 1993 and March 1994. Reproducibility was evaluated among 90 responders to the survey who answered another QFFQ six weeks later. Results: The distribution method combining postal distribution and collecting the QFFQ by interviewer as well as an offer to participate in a lottery, gave the highest response rate (72%). The possibility to get a reward increased the response rate by 9, 14 and 57%, respectively, depending on the distribution method used. The mean daily energy intake and the percentage of subjects claiming to have unlikely low energy intake did not differ signi®cantly between the different ways of distribution. In the main survey the mean ratio between energy intake and estimated basal metabolic rate was 1.58 among men and 1.47 among women, and 37% of men and 45% of women had a ratio below 1.35. Spearman rank correlations between the two QFFQ ranged from 0.48 (edible fats) to 0.91 (coffee) with a median coef®cient of 0.70. For nutrients correlations ranged from 0.55 (carbohydrate E%) to 0.81 (alcohol), with a median coef®cient of 0.72. The season of questionnaire administration was of minor importance for the reported intake of the main foods and nutrients. Conclusions: The QFFQ-method is suitable for use in a Norwegian nutritional surveillance system.

“…Although selection bias in indirectly interviewed subjects cannot be ruled out, the non-significant , relatively small interaction effects between response status and intake of carbohydrates and simple sugars argues against a strong role of this factor. Assessment of usual dietary intake in the more recent past by means of an interviewer-administered semi-quantitative food frequency questionnaire possesses adequate validity and repeatability for classifying individuals according to usual dietary intake (Jain et al, 1980;Hankin et al, 1983;Rohan et al, 1987). Yet a certain degree of measurement error related to our test instrument may have been present.…”

During 1984-88 a population-based case-control study was carried out in The Netherlands in collaboration with the International Agency for Research on Cancer in order to further explore the possible relationship between diet and exocrine pancreatic carcinoma. Past habitual dietary intake was assessed in 164 cases and 480 controls. This is the first series of population-based studies of pancreas cancer to perform a comprehensive assessment of diet. The results of logistic regression analysis, controlled for age, gender and total cigarette consumption, suggested a positive association with past habitual intake of energy in directly interviewed patients (OR highest versus lowest quintile 3.35; 95% confidence interval 1.51-7.18). No indication of an effect of Quetelet index was found. When maximum-weight-ever-achieved was used, nonsignificantly reduced risks were observed for the upper 4 quintiles of "maximum" Quetelet index. After controlling for age, gender, response status and total cigarette consumption, a positive relationship with habitual past intake of total carbohydrates was observed (OR 2.40; 95% confidence interval 1.44-3.99). The effect decreased considerably when the analysis was restricted to subjects who reported stable long-term dietary intake. After controlling for age, gender, total cigarette consumption and response status, a significant, positive association between pancreatic cancer and past habitual intake of simple sugars was found (OR 1.95; 95% confidence interval 1.24-3.07). Among those who reported stable long-term dietary intake, no effect was seen. The positive effect of simple sugars was present in males only (OR 2.15; 95% confidence interval 1.18-3.93) and was smaller in men who reported long-term stable dietary intake. Our findings suggest that the development of exocrine pancreatic carcinoma is positively related to past habitual intake of total energy, total carbohydrates and simple sugars, whereas no relationship with body-mass index was observed.

“…We examined the 'Questan' version with 172 items, which was administered in a statewide survey of the state of Victoria in 1985 21 and has been used in a national postal survey every 5 years since 1988 to assess usual food and nutrient intakes 26 . The repeatability of this FFQ has been reported 13,27 but little information about its validity relative to other dietary methods has been published, despite its extensive use. The limited reports that exist have examined only a few nutrients 3,23,28,29 , were conducted with female student dietitians 29 or compared total fruit and vegetable intakes only 30 .…”

Objectives: To compare a widely used Australian food-frequency questionnaire (FFQ) with diet records and consider the results in relation to its use in nutrition surveillance. Design: Inter-method reliability study. Setting: A randomised trial in subjects with past asbestos exposure. Subjects: Seventy-two adults living in Western Australia. Methods: A semi-quantitative FFQ developed by the Commonwealth Scientific Industrial Research Organisation in South Australia was administered after the completion of four 7-day diet records (DRs). Results: Mean agreement between methods was not significantly different from 100% for many nutrients, but the limits of agreement indicated that, at the individual level, the FFQ over-or underestimated the DR by at least 50%. Mean agreement between methods decreased significantly with increasing intakes for the majority of nutrients. Pearson's correlation coefficients were less informative indicators of agreement compared with the limits of agreement. Conclusions: These results indicate poor agreement between the FFQ and DR when estimating absolute intakes. Therefore, comparing intakes collected using this FFQ with specific cut-off points such as Recommended Dietary Intakes for nutrition surveillance may lead to seriously flawed conclusions about population intakes.
