These results suggest that children who were overweight or obese had a reduced ability to mobilise the cognitive effort required to inhibit involuntary responses and to switch between different mental operations. A developmental trajectory would provide important insights into the relationship between executive functioning pattern and the risk of being overweight or obese.

This study researched the relationship between overweight/obesity and psychological problems in children, emphasizing the interactive effects of gender, body dissatisfaction (BD) and socioeconomic status (SES). A total of 515 children with a mean age of 8.5 from Reus (Spain) were measured for weight and height and answered the Figure Rating Scale. Parents completed the Child Behavior Checklist. Children with obesity showed the greatest BD, were significantly more withdrawn/depressed (12.9% versus 3.2%) and had more aggressive behavior (9.7% versus 1.6%) than normal weight children (p = .04). The overweight and overweight/obese groups showed more somatic complaints than normal weight children (17.3% and 19.4% versus 9.4%; p = .007). The internalizing dimension, together with BD, was significantly related to the overweight/obese condition. Specifically, children with somatic complaints had a 2.64-fold increased probability of being overweight/obese. However, BD and SES did not mediate the relationship between internalizing problems and obesity. The study results support the relationship between obesity and internalizing problems in childhood.Keywords: Psychopathology; obesity; emotional problems; children. Asociación entre el sobrepeso y la obesidad con los problemas psicológicos en escolaresResumen: El presente estudio investiga la relación entre sobrepeso/obesidad y problemas psicológicos en escolares, evaluando la interacción del género, insatisfacción corporal (IC) y nivel socioeconómico (NSE). Un total de 515 niños de 8.5 años (Reus, España) fueron pesados, medidos y respondieron la Figure Rating Scale. Los padres completaron el Child Behaviour Checklist. Los niños obesos presentaron más IC, mostraron significativamente más retraimiento/depresión (12.9% versus 3.2%) y conducta agresiva (9.7% versus 1.6%) que de los de peso normal (p = .04). Los niños con sobrepeso y sobrepeso/obesidad presentaron más quejas somáticas que los de peso normal (17.3% y 19.4% versus 9.4%; p = .007). La dimensión de problemas interiorizados, junto a la IC, estuvo significativamente relacionada con el sobrepeso/obesidad. Específicamente, los niños con quejas somáticas tuvieron 2.64 veces mayor probabilidad de ser obesos. No obstante, la IC y el NSE no mediaron la relación entre problemas internalizados y obesidad. Los resultados apoyan la relación entre obesidad y los problemas interiorizados en edades tempranas.
