The purpose of the study is to investigate the effect of obesity on children's developmental trajectories of cognitive functions (sustained attention, memory, logical thinking and executive functions) of the obese and normal Egyptian school-age children and to investigate if the BMI can be used as a predictor of cognitive performance in later adolescence and adulthood. This study is a cross-sectional prospective design. A sample of 463 healthy children of both sexes, of age ranged from 6-12 years, from elementary schools in Upper Egypt was recruited. Descriptive statistical analysis revealed that the obese children made more errors than their normal-weight counterparts. Based on study's results, the obese children had lower cognitive performance than their normal-weight counterparts and the BMI can be used as a predictor for the future cognitive functions in executive functions and memory domains but not sustained attention and logical thinking.]]>APA.,20032003Badawi, N.E.S., A.A.
