This study compares externalizing behavior disorders in overweight and normal-weight boys. The statistical population includes all the male students of elementary schools in Mashhad, who were selected using the cluster sampling method, six districts, and among the schools in this district, two boys' schools and a total of 222 students were selected as the research sample. Children's Behavior Checklist (CBCL) was used as a tool in this study. The results showed that, in general, there is a significant difference in externalizing behavior disorders between overweight and normal-weight boys (P<0.05), which is seen in conduct disorder and oppositional defiant disorder. In comparison, these two groups had no significant difference in attention deficit hyperactivity disorder (P<0.05). According to the results of the research, informing and changing the attitude of parents in preventing the occurrence of obesity and overweight and ultimately behavioral problems seems necessary, and since the deviation from normal weight is related to inappropriate and risky behaviors, early interventions and appropriate planning in this field is practical and necessary during the sensitive period of childhood.
