Journal Article 2016 05 21 Introduction: Studies have shown that overweight and obesity are associated with poor executive function and cognitive abilities. This can be due to changes in the structure and function of the brain, the aim of the study was to investigate executive functions, particularly inhibition control system and problem - solving in groups of overweight and obese children compared with normal weight children. Method: design study is causal- comparative.  41 primary school students, in 7 to 12 year age, Of the population of primary school of Tehran were selected as samples available in 1395. 21 students with excess weight and 20 students with normal weight were measured in Strop test, the Tower of London tools and BMI. Results: The results of T-test showed significant differences in the ability in inhibitory system function between two groups Conclusion: According to the findings, it seems the obese children and adolescents have poorer inhibition control system than normal weight peers.  This deficiency can reduce the other cognitive abilities in long term and have an impact on children's academic and social success.
