Abstract
Background: To evaluate the association of major dietary patterns identified by factor analysis and attention deficit hyperactivity disorder (ADHD) in a group of Iranian school aged children.
Materials and Method: This cross-sectional study was conducted among 375 school-aged children in Tehran, Iran. Usual dietary intakes were assessed by a semi-quantitative food frequency questionnaire. DSM-IV questionnaire was used to determine the prevalence of ADHD. Major dietary patterns were identified by factor analysis.
Results: The prevalence of ADHD was 9.7% in this population. We identified 4 major dietary patterns: "healthy", "western", "sweet" and "fast foods" dietary patterns. Children in top quintile of "sweet dietary pattern” score had greater odds for having ADHD as compared with those in the lowest quintile (Odds ratio: 3.95 95% CI: 1.16, 15.31 p=0.03). Greater adherence to "fast food" dietary pattern was significantly associated with higher risk of having ADHD (Odds ratio: 3.21 95% CI: 1.05, 10.90 p=0.03). No overall significant associations were seen between either healthy or western dietary patterns with ADHD. All these analysis were done in the controlled model for confounders.
Conclusion: We found significant independent associations between "sweet" and "fast foods" dietary patterns and prevalence of ADHD. Prospective studies are required to confirm these findings.
