CPA) and then compared according to their BMI using non-parametric statistical methods (Mann-Whitney test). Separate comparisons were made for girls and boys. Results indicated significant differences in performance amongst the groups of girls in all the motor and perceptual activities, and in the social relationships component of the social-emotional factor. These differences seemed to penalize motor activities, perceptual skills, and social relationships in overweight and obese girls compared to normal weight girls. In the case of boys, there were significant differences in laterality and visual-motor coordination (favoring overweight boys). Differences in respiratory control were also found, but in this case, penalizing obese boys compared to normal weight boys. Knowledge of possible psychomotor limitations in obese children could allow psychologists and healthcare professionals to design more focused interventions.
