RESUMO
Introducción: La Escala de Impulsividad de Barratt (BIS) es un instrumento de autoinforme diseñado para evaluar la construcción de personalidad y comportamiento de la impulsividad. La impulsividad se ha asociado con varios trastornos psiquiátricos, como el trastorno por déficit de atención e hiperactividad (TDAH). Este estudio evalúa el progreso de la conducta de impulsividad en niños con TDAH después de una intervención dietética de 8 semanas con dieta mediterránea y/o suplemento de ácidos grasos omega-3, mediante el uso de la BIS-11 adaptada para niños (BIS-11c). Métodos: Este estudio transversal incluyó a 60 niños españoles con TDAH de la provincia de Madrid, España. Los participantes se dividieron en 4 grupos, un grupo de control (G1) y 3 grupos de intervención (dieta mediterránea [G2], suplemento de omega-3 [G3] y dieta mediterránea + suplemento de omega-3 [G4]). Se diseñó una dieta mediterránea personalizada para los grupos 2 y 4. Se administró BIS-11c para determinar los niveles de impulsividad y se usó el KIDMED para evaluar la adherencia a la dieta mediterránea. Resultados: El grupo suplemento mostró una caída bastante significativa (p = 0,049) en la puntuación total de Barratt después del seguimiento. La puntuación cognitiva total disminuyó ligeramente en los grupos de dieta y suplemento. Solo el grupo control tuvo una disminución notable con respecto a la puntuación total de la impulsividad motora. Las puntuaciones totales de «falta de planificación» fueron menores en todos los grupos tras la intervención. Las asociaciones entre las puntuaciones iniciales y finales del BIS-11c y los tratamientos presentaron una correlación positiva (r > 0,9). [...](AU)
Introduction: The Barratt Impulsiveness Scale (BIS) is a self-administered instrument designed to assess the personality/behavioural construct of impulsiveness. Impulsiveness has been associated with several psychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD). This study assesses the progression of impulsive behaviour in children with ADHD after an 8-week dietary intervention with the Mediterranean diet and/or omega-3 fatty acid supplementation, by using a version of the 11-item BIS adapted for children (BIS-11c). Methods: This cross-sectional study includes 60 children with ADHD from the region of Madrid, Spain. Participants were divided into 4 groups, with one control group (G1) and 3 intervention groups (Mediterranean diet [G2]; omega-3 supplementation [G3]; and Mediterranean diet plus omega-3 supplementation [G4]). A personalised Mediterranean diet was designed for members of groups 2 and 4. The BIS-11c was administered to determine the level of impulsiveness, and the KIDMED test was used to assess adherence to the Mediterranean diet. Results: The supplementation group showed a fairly significant decrease in the total BIS-11c (P = .049). Total cognitive score slightly decreased in the diet and supplementation groups. Only the control group showed a considerable decrease in the total motor score. Total nonplanning scores were lower in all groups after the intervention. Baseline and final BIS-11c scores were positively correlated with treatments (r > 0.9). Conclusion: An intake of 550 mg EPA fatty acid and 225 mg DHA fatty acid per day for 8 weeks is associated with less marked impulsive behaviour in children with ADHD. A Mediterranean diet may improve BIS scores, although our results are not conclusive in this population. (AU)
