Association of ADHD Symptoms With Dietary Pattern Scores.

Standardized regression coefficients are presented here because they make the comparison of effect sizes between the ADHD symptom scales comparable (e.g., one standard deviation increase of the score for Inattention and Impulsivity is associated with an increase of .09 and .14 standard deviations, of the Snack factor, respectively).
All three ADHD symptom scores in one model, with adjusted for recruitment group (conventional/alternative), maternal pre-pregnancy BMI, maternal smoking, and alcohol consumption during pregnancy, maternal age at birth, maternal education level, gestational age at birth, birthweight, and child’s sex. The ADHDi scale was not included in this multivariable linear regression due to its high overlap with the Cognitive problems/Inattention subscale.
