As for the gender in ADHD group, 56.8% was male and 43.2% was female. Normal group showed the higher breakfast consumption rate than ADHD group (p < 0.05). Dietary habits were better in normal group than ADHD group. Nutrition knowledge scores of normal group was 7.38 out of 15 and scores of ADHD group was 5.77 out of 15 (p < 0.01). The nutrition knowledge score and the dietary habits score showed a positive correlation (p < 0.01). The nutrition knowledge score and snack · meal purchasing frequency showed a negative correlation (p < 0.05). There are significant negative correlation between attention deficit hyperactivity score and nutrition knowledge score (p < 0.01).
