“…In a review of FFQ validation studies, Thompson & Byers 35 observed that correlation coefficients ranged from 0.4 to 0.7. The mean correlation coefficient for crude estimates of energy and nutrient intake presented by the present study is within an acceptable level (mean r = 0.41), and is similar to mean values found by Jackson et al 36 (r = 0.44), Kusama et al 37 (r = 0.46), Marques-Vidal et al 34 (r = 0.42), Block et al 38 and Deschamps et al 39 (r = 0.52). FFQ validation studies carried out in Brazil also showed similar values: Fornés et al 17 and Ribeiro et al 18 found a mean Pearson correlation coefficient of 0.50, and Henn et al 20 observed a mean value of 0.49.…”

“…However, their dependence on memory and the inability to incorporate direct measurements are the major limitations of 24hDR. Some previous studies used dietary recalls (35)(36)(37)(38)(39) and other studies used diet records (31,40) . It seems that characteristics of the study population are important for choosing the reference method, as the diet record is probably not applicable in populations with low or moderate education, or in populations not very experienced in recording food intake, such as the population in the present study.…”

Objective: To describe the relative validity and reliability of the FFQ used for assessing nutrient intakes of participants in the Tehran Lipid and Glucose Study (TLGS). Design: A total of 132 subjects (sixty-one males and seventy-one females) were included in the study. Dietary data were collected monthly by means of twelve 24 h dietary recalls (24hDR). Subjects completed two, 168-item semi-quantitative FFQ. Blood and urine samples were taken every season for measurement of plasma biomarkers and urinary N and K. Results: Mean age and BMI of the participants were 35?5 (SD 16?8) years and 25?5 (SD 5?2) kg/m 2 , respectively. The mean energy-adjusted and deattenuated correlation coefficients for overall nutrient intake between the 24hDR and FFQ2 were 0?44 and 0?37 in #35-year-olds and .35-year-olds, respectively, and for individual nutrients ranged from 0?24 to 0?71 in men (mean r 5 0?53) and from 0?11 to 0?60 in women (mean r 5 0?39). The mean energy-adjusted reliability coefficients varied from 0?48 in #35-year-olds to 0?65 in .35-year-olds, and ranged from 0?41 to 0?79 in men (mean r 5 0?59) and from 0?39 to 0?74 in women (mean r 5 0?60). The FFQ2 and 24hDR produced exact agreement rates ranging between 39?6 % and 68?3 % in men and between 39?6 % and 54?1 % in women. The ranges of questionnaire validity coefficients, with the sample correlation between the questionnaires and biochemical marker as the lower limit and the estimate obtained by the method of triads as the upper limit, were 0?21-0?56 (protein) and 0?37-0?61 (K). Conclusions: The FFQ developed for the TLGS has reasonable relative validity and reliability for nutrient intakes in Tehranian adults.

“…However, if the time interval is too long, dietary patterns may change, affecting the study's reliability. (34) The energy, CHO and protein intake reported were higher in FFQ1 compared to FFQ2. In general, food intake during the fi rst administration of an FFQ is higher than that during the second.…”

INTRODUCTIONThis study aimed to develop and validate a food frequency questionnaire (FFQ) to assess habitual diets of multi-ethnic Malaysian children aged 7-12 years.METHODS A total of 236 primary school children participated in the development of the FFQ and 209 subjects participated in the validation study, with a subsample of 30 subjects participating in the reproducibility study. The FFQ, consisting of 94 food items from 12 food groups, was compared with a three-day dietary record (3DR) as the reference method. The reproducibility of the FFQ was assessed through repeat administration (FFQ2), seven days after the fi rst administration (FFQ1). RESULTSThe results of the validation study demonstrated good acceptance of the FFQ. Mean intake of macronutrients in FFQ1 and 3DR correlated well, although the FFQ intake data tended to be higher. Cross-classifi cation of nutrient intake between the two methods showed that < 7% of subjects were grossly misclassifi ed. Moderate correlations noted between the two methods ranged from r = 0.310 (p < 0.001) for fat to r = 0.497 (p < 0.001) for energy. The reproducibility of the FFQ, as assessed by Cronbach's alpha, ranged from 0.61 (protein) to 0.70 (energy, carbohydrates and fat). Spearman's correlations between FFQ1 and FFQ2 ranged from rho = 0.333 (p = 0.072) for protein to rho = 0.479 (p < 0.01) for fat.CONCLUSION These fi ndings indicate that the FFQ is valid and reliable for measuring the average intake of energy and macronutrients in a population of multi-ethnic children aged 7-12 years in Malaysia.

Reproducibility and Validity of a Food Frequency Questionnaire among Vietnamese in Ho Chi Minh City

Abstract: This food frequency questionnaire measured the usual intake of major nutrients for Vietnamese adults living in Ho Chi Minh City and its urban area, where dietary patterns are similar to those of the Vietnamese population.
