BackgroundTo date, no culture-specific food frequency questionnaires (FFQ) are available in North Africa. The aim of this study was to adapt and examine the reproducibility and validity of an FFQ or use in the Moroccan population.MethodsThe European Global Asthma and Allergy Network (GA2LEN) FFQ was used to assess its applicability in Morocco. The GA2LEN FFQ is comprised of 32 food sections and 200 food items. Using scientific published literature, as well as local resources, we identified and added foods that were representative of the Moroccan diet. Translation of the FFQ into Moroccan Arabic was carried out following the World Health Organization (WHO) standard operational procedure. To test the validity and the reproducibility of the FFQ, 105 healthy adults working at Hassan II University Hospital Center of Fez were invited to answer the adapted FFQ in two occasions, 1 month apart, and to complete three 24-h dietary recall questionnaires during this period. Pearson correlation, and Bland-Altman plots were used to assess validity of nutrient intakes. The reproducibility between nutrient intakes as reported from the first and second FFQ were calculated using intra-class correlation coefficient (ICC). All nutrients were log-transformed to improve normality and were adjusted using the residual method.ResultsThe adapted FFQ was comprised of 255 items that included traditional Moroccan foods. Eighty-seven adults (mean age 27.3 ± 5.7 years) completed all the questionnaires. For energy and nutrients, the intakes reported in the FFQ1 were higher than the mean intakes reported by the 24-h recall questionnaires. The Pearson correlation coefficients between the first FFQ and the mean of three 24-h recall questionnaires were statistically significant. For validity, de-attenuated correlations were all positive, statistically significant and ranging from 0.24 (fiber) to 0.93 (total MUFA). For reproducibility, the ICCs were statistically significant and ranged between 0.69 for fat and 0.84 for Vitamin A.ConclusionThis adapted FFQ is an acceptable tool to assess usual dietary intake in Moroccan adults. Given its representativeness of local food intake, it can be used as an instrument to investigate the role of diet on health and disease outcomes.

“…In a French study with adults, finding correlation coefficients less than 0.3 in 8 nutrients, among these vitamin B 12 25 , low correlations for vitamins can be attributed to implicit bias of the FFQ 26 . In the literature, the validity has been reached for most macronutrients, but micronutrients, in general, have the lowest values of correlation coefficient 9,10,19 , other studies also show low correlation for protein 27 , data likewise found in our study.…”

Background: To investigate the association between diet and health effects in population surveys, it is necessary to have precise tools that allow estimating the habitual consumption of the population. Introduction: To investigate the association between diet and health effects in population surveys, it is necessary to have precise tools that allow estimating the habitual consumption of the population. Aim: To evaluate the reproducibility and validity of the ELSA-Brasil food frequency questionnaire (FFQ) to assess macro and micronutrients intake. Material and methods: We collected dietary information of 281 participants which completed two ELSA-Brasil food frequency questionnaires (FFQ) over a year period and three records. To assess the reproducibility of the FFQ, we compared the macro and micronutrients intake from the two FFQ while to assess the validity, we compared the intakes of FFQ with the mean of three records. The intraclass correlation test (ICC) and agreement percentages of nutrient intake were calculated after categorization by tertiles. Results: ICC coefficients for reproducibility ranged from 0.51 (polyunsaturated fat) to 0.70 (magnesium) while the ICC coefficients for validity ranged from 0.14 to 0.61 for omega 3 and magnesium, respectively. The exact concordances between methods ranged from 37% for omega 3 to 50.2% for magnesium (mean = 44.6%). An average disagreement of 13.4% was found. Conclusions: This study suggests that the ELSA-Brasil FFQ is suitable tool to assess dietary intake with a satisfactory reproducibility and relative validity.

“…Depending on the aim of the study, various types of FFQs are developed and applied-either un-quantified ones, where product intakes, but not nutrient intakes, are assessed, 34 or semi-quantitative and quantitative ones, where nutrient intakes are assessed. 35 Moreover, quantitative questionnaires include both comprehensive ones to assess the intake of many nutrients 17 and brief ones to assess the intake of one nutrient 36 or a few nutrients related to a certain disease. 37 At the same time, brief FFQs are especially valuable, as they are developed to assess the intake of just a few food items and thus significantly reduce the number of questions, which is less than 50.…”

Aim The aim of the study was to develop and validate the semi‐quantitative brief food frequency questionnaire to assess the magnesium intake (Mg‐FFQ). Methods The developed questionnaire consists of 39 questions and it was validated in a group of 75 women aged 20‐30. The validity was assessed with reference to the 3‐day dietary record and the reproducibility was assessed for a period of 6 weeks. Results The Bland‐Altman index for the assessment of validity was 6.7% and for reproducibility—8.0%, while the kappa statistic indicated a slight and substantial agreement, respectively. The high reproducibility was confirmed by a high share of respondents correctly classified into tertiles (73.3%) and correctly classified into categories of adequate/inadequate intake (85.3%). Conclusion For the developed and validated Mg‐FFQ, a high reproducibility, accompanied by a satisfactory validity, was confirmed, so it may be used to assess the magnesium intake in the epidemiological studies in young Polish women aged 20‐30.
