Repeatability and validity of a food frequency and dietary habits questionnaire in children.Farajian P, Karasouli K, Risvas G, Panagiotakos DB, Zampelas AUnit of Human Nutrition, Department of Food Science, Agricultural University of Athens, Athens, GreeceAim:  This work aimed to assess  the relative  validity  and repeatability  of  a  semi-quantitative food  frequency  questionnaire  (FFQ)  in  children.  Methods:  Dietary intakes and habits were assessed using the FFQ that contained all basic foods and food-groups, as well as beverages and a 3-d dietary record as the reference method. Eighty-two healthy children (47 girls and 35 boys), 11-12 years old, were recruited from public schools and asked to fulfil the FFQ and also to provide non-consecutive 3-d  dietary  records.  The  repeatability  of  the  FFQ  was  assessed  by  repeated administration  in  the  same  children  two  weeks  after  the  first  completion.  Data analysis  was  based  on  Wilcoxon  non-parametric  pairwise  comparisons  test  and Spearman’s  correlation  coefficient,  after  energy intake  adjustment.  Results:  There were no significant differences between the two examinations for most foods and food groups’ frequency consumption, as well as between the reported dietary and everyday living habits known to affect obesity status. W-test values ranged between -1.77 to -0.13  (all  p-values  >0.1).  Moreover,  hours  of  TV  viewing  were  associated  with increased saturated fatty acid (SAFA), dietary cholesterol and sodium intake, while eating outside home was inversely associated with monounsaturated fatty acids and calcium intake. Breakfast skipping was associated with increased total fat and SAFA dietary  intake,  while  children  that  reported  having  breakfast  also  had  increased carbohydrates  and  vitamin  C  intake.  Additionally,  significant  correlations  were observed for some energy dense foods, such as burgers, pizza, salty snacks, ice cream, and  fried  potatoes  and  total  energy  intake.  Spearman  correlations  between  the aforementioned  factors  ranged  from -0.45  to  0.55  (all  p-values<0.05).  No gender differences  were  observed  in  all  analyses  reported.  Conclusion:  The  applied questionnaire  is  a repeatable  and valid  tool  to  investigate  the association  between dietary habits, total energy intake and dietary nutrients.
