Original article: adolescent dietary patterns derived using principal component analysis and neuropsychological functions: a cross-sectional analysis of Walnuts Smart Snack cohort.

We aimed to analyze the association between dietary patterns and neuropsychological outcomes in a sample of healthy adolescents of the Walnuts Smart Snack (WSS) cohort from Barcelona city. We performed principal components analysis (PCA) to determine dietary patterns in the adolescent sample using a food frequency questionnaire (60 items). Multiple linear regression models were performed to analyze the association between PCA dietary patterns with neuropsychological outcomes: Strengths and Difficulties (SDQ) externalizing and internalizing scores, Attention Network Test (ANT) Impulsivity Index and Emotional Recognition Task (ERT) scores. We additionally adjusted the models for child sex, age, body mass index (BMI), physical activity and maternal education. Six dietary patterns were identified in PCA analyses. "low consumption of calorie-dense foods" dietary pattern had a negative association (protective) with the both SDQ outcomes (p value < 0.001) and "Nuts" dietary pattern showed a negative (protective) association with impulsivity index (β1 = -24.60, 95% CI = -36.80, -12.41, p value < 0.001). Overall, our main results suggest that healthy dietary patterns, including higher intakes of "nuts" and a preference of "low consumption of calorie-dense foods" dietary patterns, could provide a beneficial association with neuropsychological functions during the adolescence period. The associations may include improvements of externalizing and internalizing problem symptoms, and impulsivity.application/pdfeng© The Author(s) 2024.
