AB  - BACKGROUND: The food frequency questionnaire (FFQ) is the most efficient and 
      cost-effective method to investigate the relationship between usual diet and 
      disease in epidemiologic studies. Although FFQs have been validated in many adult 
      populations worldwide, the number of valid FFQ in preschool children is very 
      scarce. The aim of this study was to evaluate the reproducibility and validity of 
      a semi-quantitative FFQ designed for children aged 4 to 5 years. MATERIALS AND 
      METHODS: In this study, we have included 169 children aged 4-5 years from the 
      INMA project in Valencia, a population-based prospective cohort study of mothers 
      and children in Spain. The 105-items FFQ was administered twice to the parents or 
      care-givers of children over a 9-month period. Reproducibility was explored by 
      comparing intake of nutrients by the FFQs, while validity was examined by 
      comparing the nutrient values from the FFQs with the average nutrient values of 
      three 24 hour dietary recall (24hDR) taken in the period, and also, with the 
      concentration in blood specimens for several vitamins (carotenoids, folate, 
      vitamin B12, vitamin C and alpha-tocopherol). Pearson correlation coefficients and 
      de-attenuated correlation coefficients were calculated and we also evaluated 
      misclassification by quintile distribution. RESULTS: All correlation coefficients 
      for reproducibility for nutrients and major food groups were statistically 
      significant; the average correlation coefficients for daily intake were 0.43 for 
      food groups and 0.41 for nutrients. The average correlation coefficients for 
      validity for daily intakes against 24hDR was r = 0.30, and the average for 
      de-attenuated correlation coefficients was r = 0.44. When evaluating validity 
      against the blood concentration of vitamins, statistically significant 
      correlations were observed for vitamin C (0.35), lycopene (0.31), beta-Cryptoxantin 
      (0.40), and vitamin E (0.29); the average of correlation coefficients was r = 
      0.21. CONCLUSION: Despite some low to moderate correlations for reproducibility 
      and validity, overall this study suggests that the FFQ may be a good method for 
      assessing a wide range of food groups and nutrients intake in children aged 4-5 
      years.
