Abstract
Background: Determining the relationship between diet and health outcomes in children requires reproducible and validated long-term dietary assessment tools such as food frequency questionnaire (FFQ). Objective: To test the reproducibility and relative validity of a FFQ for young children against 24-hour food recalls (24HRs), anthropometric measurements, and a comprehensive feeding practices questionnaire (CFPQ). Design and setting: Children (aged 5-6) and their mothers were recruited during one school-year (2008) from preschools. Children's anthropometric measurements were obtained and mothers provided during a personal interview on three occasions a 110-item semiquantitative FFQ, 24HRs and CFPQ. Statistical analyses performed: Pearson correlation coefficients were calculated to assess the reliability of the FFQ and the relative validity compared to the 24HR. Validity coefficients between the FFQ and the different measurements were calculated. Scores of the 12 factors of the CFPQ were calculated and dietary intake was compared across CFPQ tertiles using ANOVA. Results: Sixty-six healthy children (47% boys) were recruited. The FFQ seemed to overestimate the nutrient intake when compared with 24HRs. Pearson's correlations between the average of the FFQs and the average of the 24HRs ranged from 0.3-0.6 (P
